    Time and again, floods around the world illustrate the devastating impact they can have on societies. Furthermore, the expectation that the flood damages can increase over time with climate, land-use change and social growth in flood prone-areas has raised the public and other stakeholders' (governments, international organization, re-insurance companies and emergency responders) awareness for the need to manage risks in order to mitigate their causes and consequences. In this light, the choice of appropriate measures, the assessment of the costs and effects of such measures, and their prioritization are crucial for decision makers. As a result, a priori flood risk assessment has become a key part of flood management practices with the aim of minimizing the total costs related to the risk management cycle. In this context, The EU Flood Directive 2007/60 requires the delineation of flood risk maps on the bases of most appropriate and advanced tools, with particular attention on limiting required economic efforts. The main aim of these risk maps is to provide the required knowledge for the development of flood risk management plans (FRMPs) by considering both costs and benefits of alternatives and results from consultation with all interested parties. In this context, this research project developed a free and open-source (FOSS) GIS software, called FloodRisk, to operatively support stakeholders in their compliance with the FRMPs. FloodRisk aims to facilitate the development of risk maps and the evaluation and management of current and future flood risk for multi-purpose applications. This new approach overcomes the limits of the expert-drive qualitative (EDQ) approach currently adopted in several European countries, such as Italy, which does not permit a suitable evaluation of the effectiveness of risk mitigation strategies, because the vulnerability component cannot be properly assessed. Moreover, FloodRisk is also able to involve the citizens in the flood

  5. A free and open source QGIS plugin for flood risk analysis: FloodRisk

    Science.gov (United States)

    Albano, Raffaele; Sole, Aurelia; Mancusi, Leonardo

    2016-04-01

    An analysis of global statistics shows a substantial increase in flood damage over the past few decades. Moreover, it is expected that flood risk will continue to rise due to the combined effect of increasing numbers of people and economic assets in risk-prone areas and the effects of climate change. In order to increase the resilience of European economies and societies, the improvement of risk assessment and management has been pursued in the last years. This results in a wide range of flood analysis models of different complexities with substantial differences in underlying components needed for its implementation, as geographical, hydrological and social differences demand specific approaches in the different countries. At present, it is emerging the need of promote the creation of open, transparent, reliable and extensible tools for a comprehensive, context-specific and applicable flood risk analysis. In this context, the free and open-source Quantum GIS (QGIS) plugin "FloodRisk" is a good starting point to address this objective. The vision of the developers of this free and open source software (FOSS) is to combine the main features of state-of-the-art science, collaboration, transparency and interoperability in an initiative to assess and communicate flood risk worldwide and to assist authorities to facilitate the quality and fairness of flood risk management at multiple scales. Among the scientific community, this type of activity can be labelled as "participatory research", intended as adopting a set of techniques that "are interactive and collaborative" and reproducible, "providing a meaningful research experience that both promotes learning and generates knowledge and research data through a process of guided discovery"' (Albano et al., 2015). Moreover, this FOSS geospatial approach can lowering the financial barriers to understanding risks at national and sub-national levels through a spatio-temporal domain and can provide better and more complete

    Peng, Szu-Hsien

    2018-02-26

    To evaluate flood-prone areas, correlation analysis of flooding factors for the quantitative evaluation of hazard degree was determined to assist in further disaster prevention management. This study used flood-prone areas in 35 villages over eight townships (Changhua, Huatan, Yuanlin, Xiushui, Puyan, Hemei, Dacun, and Erlin) in Changhua County as research samples. Linear combination was used to evaluate flood-prone environmental indices, and an expert questionnaire was designed by using the analytic hierarchy process and the Delphi method to determine the weights of factors. These factors were then used to calculate the eigenvector of a pairwise comparison matrix to obtain the weights for the risk assessment criteria. Through collection of disaster cases, with particular focus on specifically protected areas where flooding has occurred or is likely to occur, public adaptation and response capabilities were evaluated by using an interview questionnaire that contains the items of perceived disaster risk, resource acquisition capability, adaptation capability, and environment understanding and disaster prevention education. Overlays in a geographic information system were used to analyze the flood-risk degree in villages and to construct a distribution map that contains flood-prone environment indices. The results can assist local governments in understanding the risk degree of various administrative areas to aid them in developing effective mitigation plans.

  8. Uncertainty and Sensitivity of Direct Economic Flood Damages: the FloodRisk Free and Open-Source Software

    Science.gov (United States)

    Albano, R.; Sole, A.; Mancusi, L.; Cantisani, A.; Perrone, A.

    2017-12-01

    The considerable increase of flood damages in the the past decades has shifted in Europe the attention from protection against floods to managing flood risks. In this context, the expected damages assessment represents a crucial information within the overall flood risk management process. The present paper proposes an open source software, called FloodRisk, that is able to operatively support stakeholders in the decision making processes with a what-if approach by carrying out the rapid assessment of the flood consequences, in terms of direct economic damage and loss of human lives. The evaluation of the damage scenarios, trough the use of the GIS software proposed here, is essential for cost-benefit or multi-criteria analysis of risk mitigation alternatives. However, considering that quantitative assessment of flood damages scenarios is characterized by intrinsic uncertainty, a scheme has been developed to identify and quantify the role of the input parameters in the total uncertainty of flood loss model application in urban areas with mild terrain and complex topography. By the concept of parallel models, the contribution of different module and input parameters to the total uncertainty is quantified. The results of the present case study have exhibited a high epistemic uncertainty on the damage estimation module and, in particular, on the type and form of the utilized damage functions, which have been adapted and transferred from different geographic and socio-economic contexts because there aren't depth-damage functions that are specifically developed for Italy. Considering that uncertainty and sensitivity depend considerably on local characteristics, the epistemic uncertainty associated with the risk estimate is reduced by introducing additional information into the risk analysis. In the light of the obtained results, it is evident the need to produce and disseminate (open) data to develop micro-scale vulnerability curves. Moreover, the urgent need to push

    CERN Document Server

    Kleinknecht, Konrad

    2015-01-01

    Der Ausstieg aus der Nutzung der Kernenergie in Deutschland wurde im Sommer 2011 im Eiltempo beschlossen. Jetzt zeigt sich, dass es keinen realistischen Plan für den Umbau der Energieversorgung in der vorgesehenen Frist von zehn Jahren gibt. Für die Umstellung unserer gesamten Stromversorgung und damit unserer Wirtschaft ist der Zeitraum zu kurz. Es fehlt eine belastbare empirische Begründung, die Fragen der Versorgungssicherheit, der Finanzierbarkeit, der Auswirkungen auf die wirtschaftliche Entwicklung und die soziale Gerechtigkeit behandeln müsste. Somit droht diese Wende an ihren Widersprüchen zu scheitern. Konrad Kleinknecht versucht in seinem Buch, die Probleme zu benennen und Antworten zu finden. Für ihn stellen sich die folgenden Fragen: Welche Möglichkeit haben wir, mit Windkraft und Solarenergie einen Teil der Stromversorgung zu ersetzen? Welche Stromquellen bieten gesicherte Leistung? Können wir auf Kohlekraftwerke verzichten? Brauchen wir neue Stromtrassen? Wie lässt sich Strom speichern?...

  1. Zusammenarbeit aus Sicht eines outgesourcten Instandhalters

    Science.gov (United States)

    Grüßer, Stefan; Loeven, Heinz-Wilhelm

    Dauerhafter Unternehmenserfolg ist nur mit einer fortschrittlichen Instandhaltung zu erzielen. Durch den enormen Kostendruck infolge der Globalisierung und die Innovationssprünge auf der technischen Seite wird auch die Frage nach der modernen Organisationsform für die Instandhaltung gestellt. Eine Möglichkeit der Kostenoptimierung ist das Outsourcing von Instandhaltungsleistungen. Hierbei ist es unerlässlich, dass sich die Mitarbeiter zum Dienstleister entwickeln. In diesem Beitrag wird die Entwicklung der InfraServ Knapsack von einer internen Instandhaltungsabteilung hin zu einem Industriellen Dienstleister beschrieben und Aspekte der Zusammenarbeit mit externen Kunden aus der Sicht des outgesourcten Instandhalters geschildert. Es werden die wichtigen Entwicklungsschritte zur Dienstleistungsorientierung der früheren Eigeninstandhaltung aufgezeigt. Dieser Beitrag ist nicht als "Königsweg“ zu verstehen, er soll vielmehr anhand der Erfahrungen einer outgesourcten Eigeninstandhaltung Anregungen für die Entwicklung der eigenen Instandhaltungsorganisation liefern.

    Full Text Available In der Urologie hat die Zertrümmerung von schmerzhaften Nierensteinen mittels extrakorporaler Stoßwellen die nicht-invasive Therapie von Nierensteinen revolutioniert. Dieses erfolgversprechende Konzept wurde vor über 15 Jahren in der Orthopädie aufgegriffen. Dabei wurde versucht, die verzögerte Knochenbruchheilung durch Stimulation der Knochenenden mit Hilfe fokussierter extrakorporaler Stoßwellen zu beschleunigen. Im folgenden wurde dieses Verfahren erfolgreich zur Behandlung von Knochenbruchheilungsstörungen, der Tendinitis calcarea, der Epicondylitis radialis humeri und der Fasciitis plantaris eingesetzt. Dabei ist – anders als bei der Nierensteinzertrümmerung – nicht die Zerstörung von Hartgewebe für den Wirkmechanismus verantwortlich. Lange Zeit waren die Kenntnisse sowohl über die Wirkmechanismen extrakorporaler Stoßwellen am Knochen, als auch über mögliche unerwünschte Nebenwirkungen nur eingeschränkt verfügbar. In den letzten Jahren sind jedoch viele neue Studien publiziert worden. Die vorliegende Arbeit faßt den entsprechenden gegenwärtigen Kenntnisstand über die Wirkung extrakorporaler Stoßwellen auf den Knochen aus tier- und zellkulturexperimentellen Grundlagenuntersuchungen zusammen. Insbesondere in bezug auf mögliche unerwünschte Nebenwirkungen der ESWT haben die bisher durchgeführten Untersuchungen wertvolle Hinweise ergeben. Darüber hinaus konnten in jüngster Zeit erste Ergebnisse bezüglich der molekularen Wirkweise extrakorporaler Stoßwellen am Stütz- und Bewegungsapparat vorgelegt werden, die ein komplexes Bild der tatsächlichen Vorgänge erahnen lassen. Durch eine Intensivierung der tierexperimentellen Grundlagenforschung zur ESWT wird es möglich sein, in naher Zukunft eine breit abgesicherte, experimentell-wissenschaftliche Grundlage zum Einsatz extrakorporaler Stoßwellen am Stütz- und Bewegungsapparat zu erarbeiten.

    2002-04-01

    The textbook discusses the available options for power and heat generation from biomass as well as the limits of biomass-based power supply. The main obstacle apart from the high cost is a lack of knowledge, which the book intends to remedy. It addresses students of agriculture, forestry, environmental engineering, heating systems engineering and apprentice chimney sweepers, but it will also be useful to all other interested readers. [German] Biomasse kann aufgrund seiner vielfaeltigen Erscheinungs- und Umwandlungsformen sowohl als Brennstoff zur Waerme- und Stromgewinnung oder als Treibstoff eingesetzt werden. Die energetische Nutzung von Biomasse birgt zudem nicht zu verachtende Vorteile. Zum einen wegen des Beitrags zum Klimaschutz aufgrund der CO{sub 2}-Neutralitaet oder einfach, weil Biomasse immer wieder nachwaechst und von fossilen Ressourcen unabhaengig macht. All den bisher erschlossenen Moeglichkeiten der energetischen Nutzung von Biomasse moechte dieses Lehrbuch Rechnung tragen. Es zeigt aber auch die Grenzen auf, die mit der Energieversorgung durch Bioenergie einhergehen. Hohe Kosten und ein erhebliches Informationsdefizit behinderten bisher eine verstaerkte Nutzung dieses Energietraeges. Letzterem soll dieses Lehrbuch entgegenwirken. Das vorliegende Lehrbuch wurde fuer die Aus- und Weiterbildung erstellt. Es richtet sich vor allem an angehende Land- und Forstwirte, Umwelttechniker, Heizungsbauer und Schornsteinfeger, ist aber auch fuer all diejenigen interessant, die das Thema ''Energie aus Biomasse'' verstehen und ueberblicken moechten.

    Full Text Available 2004 erwarb die Universitätsbibliothek in Thorn einen kleinen Bestand, das Privatarchiv der Familie Szwojnicki, die bis zum Zweiten Weltkrieg ihre Landgüter in Borkłojnie in der Republik Litauen inne hatte. Die von den nacheinander folgenden Familienvertretern gesammelten Materialien, die sich bis zum heutigen Tag bewährten, erlauben die wichtigsten Schicksale dieser Familie wiederherzustellen. Die Szwojnickis waren eine Familie der Landesbeamten. Im 19. Jahrhundert waren ihre Landgüter in Borkłojnie ein Hort, wo die polnischen Truppen während des Januaraufstandes unterstützt, geschützt und versorgt wurden. Die Landgüter wurden von 1897 bis zum Ende des Zweiten Weltkrieges von Zygmunt Szwojnicki verwaltet. In der Zwischenkriegszeit bemühte er sich aktiv um die Bewahrung der nationalen Identität der in der Republik Litauen lebenden Polen. 1946 wurde er zusammen mit anderen Polen in den polnischen Staat umgesiedelt. Das ganze Familienarchiv Szwojnickis ist einer der kleineren Archivbestände, die in der Universitätsbibliothek in Thorn aufbewahrt werden. Dazu gehörten insgesamt 12 Inventareinheiten. Das älteste Dokument in diesem Bestand stammt aus dem Jahr 1531, das jüngste aus dem Jahr 1946. Die erhaltenen Archivalien entstanden also innerhalb von über 400 Jahren. Sie schildern die Schicksale der Familie Szwojnicki und ihrer Landgüter in Borkłojnie. Der Archivbestand der Familie Szwojnicki ist ein typisches Beispiel von Familienakten des nicht so wohlhabenden polnischen Adels, der die Gebiete Litauens bewohnte. Es bewährten sich vor allem die Urkunden, die von den Ansprüchen der Familie auf den Adelstitel sowie auf die Landgüter zeugen, darüber hinaus: Matrikelakten, Testamente, Finanzurkunden sowie biografische Materialien in Bezug auf den letzten Eigentümer Zygmunt Szwojnicki.

  14. The Yeast Plasma Membrane ATP Binding Cassette (ABC) Transporter Aus1

    Marek, Magdalena; Milles, Sigrid; Schreiber, Gabriele; Daleke, David L.; Dittmar, Gunnar; Herrmann, Andreas; Müller, Peter; Pomorski, Thomas Günther

    2011-01-01

    The ATP binding cassette (ABC) transporter Aus1 is expressed under anaerobic growth conditions at the plasma membrane of the yeast Saccharomyces cerevisiae and is required for sterol uptake. These observations suggest that Aus1 promotes the translocation of sterols across membranes, but the precise transport mechanism has yet to be identified. In this study, an extraction and purification procedure was developed to characterize the Aus1 transporter. The detergent-solubilized protein was able to bind and hydrolyze ATP. Mutagenesis of the conserved lysine to methionine in the Walker A motif abolished ATP hydrolysis. Likewise, ATP hydrolysis was inhibited by classical inhibitors of ABC transporters. Upon reconstitution into proteoliposomes, the ATPase activity of Aus1 was specifically stimulated by phosphatidylserine (PS) in a stereoselective manner. We also found that Aus1-dependent sterol uptake, but not Aus1 expression and trafficking to the plasma membrane, was affected by changes in cellular PS levels. These results suggest a direct interaction between Aus1 and PS that is critical for the activity of the transporter. PMID:21521689

    Full Text Available DNA fingerprinting and genetic diversity of 94 Aus (6 BRRI released Aus variety and 88 local Aus landraces genotypes were carried out to protect the Aus landraces from biopiracy. A total of 91 microsatellite markers were tested for screening the genotypes. Among 91 amplified products, 56% have polymorphic bands giving 195 alleles. The number of alleles per locus ranged from four (RM25 and RM147 to twenty seven (RM519, where average allele number was 9.76. The Polymorphism Information Contents (PIC lied between 0.455 (RM5 to 0.934 (RM519. Most robust marker was found RM519 since it provided the highest PIC value (0.934. Pair-wise genetic dissimilarity co-efficient showed the lowest genetic dissimilarity was found BRRI dhan42 and BRRI dhan43 and the highest genetic dissimilarity was found local landraces each other. Here it is shown that most Aus landraces is recognized to have broad genetic base. Thus it is recommended to use these landraces for future breeding program or include new and untouched local landraces to incorporate new genes and broaden genetic base.

    Traditional varieties and landraces belonging to the aus-type group of rice (Oryza sativa L.) are known to be highly tolerant to environmental stresses, such as drought and heat, and are therefore recognized as a valuable genetic resource for crop improvement. Using two aus-type (Dular, N22) and two drought intolerant irrigated varieties (IR64, IR74) an untargeted metabolomics analysis was conducted to identify drought-responsive metabolites associated with tolerance. The superior drought tolerance of Dular and N22 compared with the irrigated varieties was confirmed by phenotyping plants grown to maturity after imposing severe drought stress in a dry-down treatment. Dular and N22 did not show a significant reduction in grain yield compared to well-watered control plants, whereas the intolerant varieties showed a significant reduction in both, total spikelet number and grain yield. The metabolomics analysis was conducted with shoot and root samples of plants at the tillering stage at the end of the dry-down treatment. The data revealed an overall higher accumulation of N-rich metabolites (amino acids and nucleotide-related metabolites allantoin and uridine) in shoots of the tolerant varieties. In roots, the aus-type varieties were characterised by a higher reduction of metabolites representative of glycolysis and the TCA cycle, such as malate, glyceric acid and glyceric acid-3-phosphate. On the other hand, the oligosaccharide raffinose showed a higher fold increase in both, shoots and roots of the sensitive genotypes. The data further showed that, for certain drought-responsive metabolites, differences between the contrasting rice varieties were already evident under well-watered control conditions. The drought tolerance-related metabolites identified in the aus-type varieties provide a valuable set of protective compounds and an entry point for assessing genetic diversity in the underlying pathways for developing drought tolerant rice and other crops.

  9. FRAX (Aus) and falls risk: Association in men and women.

    Holloway, Kara L; Kotowicz, Mark A; Lane, Stephen E; Brennan, Sharon L; Pasco, Julie A

    2015-07-01

    The WHO fracture risk prediction tool (FRAX®) utilises clinical risk factors to estimate the probability of fracture over a 10-year period. Although falls increase fracture risk, they have not been incorporated into FRAX. It is currently unclear if FRAX captures falls risk and whether addition of falls would improve fracture prediction. We aimed to investigate the association of falls risk and Australian-specific FRAX. Clinical risk factors were documented for 735 men and 602 women (age 40-90 yr) assessed at follow-up (2006-2010 and 2000-2003, respectively) of the Geelong Osteoporosis Study. FRAX scores with and without BMD were calculated. A falls risk score was determined at the time of BMD assessment and self-reported incident falls were documented from questionnaires returned one year later. Multivariable analyses were performed to determine: (i) cross-sectional association between FRAX scores and falls risk score (Elderly Falls Screening Test, EFST) and (ii) prospective relationship between FRAX and time to a fall. There was an association between FRAX (hip with BMD) and EFST scores (β = 0.07, p risk of incident falls increased with increasing FRAX (hip with BMD) score (unadjusted HR 1.04, 95% CI 1.02, 1.07). After adjustment for age and sex, the relationship became non-significant (1.01, 95% CI 0.97, 1.05). There is a weak positive correlation between FRAX and falls risk score, that is likely explained by the inclusion of age and sex in the FRAX model. These data suggest that FRAX score may not be a robust surrogate for falls risk and that inclusion of falls in fracture risk assessment should be further explored. Copyright © 2015 Elsevier Inc.

    The US 3M Company is the producer of the 'Scotchply' glass fibre prepreg which results in materials that can withstand higher dynamic loads than conventional glass fibre reinforced plastics. The new materials are used, e.g., for leaf spring construction. The fatigue characteristics of GFRP leaf springs were discussed at the DGM 'Verbundwerkstoffe und Werkstoffverbunde' conference at Kaiserslauter in September 1997. This contribution presents tools for the engineer for calculation of leaf springs in consideration of the expected loads. [German] Bereits frueher konnte nachgewiesen werden, dass mit Glasgarngelegen verstaerkte Kunststoffe dynamisch hoeher beansprucht werden koennen als gleichartige Konstruktionen mit Glasgewebeverstaerkung. Dieser Vorteil wird in der industriellen Praxis genutzt, um den breiten Einsatzbereich von Blattfedern aus Stahl durch solche aus Faserverbundwerkstoffen zu erweitern. Mit Glasfasern verstaerkte Kunststoffe (GFK) sind seit Jahren Stand der Technik. Die Verarbeitung als Gelegeprepreg hat sich oekonomisch und oekologisch als eine guenstige Technologie bewaehrt. Die Prepregs werden im Wickelverfahren in die endgueltige Form gebracht oder zu Platten verpresst, aus denen die gewuenschten Werkstuecke mechanisch herausgearbeitet werden.

    Rice is a vital staple crop for Bangladesh and surrounding countries, with interannual variation in yields depending on climatic conditions. We compared Bangladesh yield of aus rice, one of the main varieties grown, from official agricultural statistics with Vegetation Health (VH) Indices [Vegetation Condition Index (VCI), Temperature Condition Index (TCI) and Vegetation Health Index (VHI)] computed from Advanced Very High Resolution Radiometer (AVHRR) data covering a period of 15 years (1991-2005). A strong correlation was found between aus rice yield and VCI and VHI during the critical period of aus rice development that occurs during March-April (weeks 8-13 of the year), several months in advance of the rice harvest. Stepwise principal component regression (PCR) was used to construct a model to predict yield as a function of critical-period VHI. The model reduced the yield prediction error variance by 62% compared with a prediction of average yield for each year. Remote sensing is a valuable tool for estimating rice yields well in advance of harvest and at a low cost.

  14. AUS, Neutron Transport and Gamma Transport System for Fission Reactors and Fusion Reactors

    International Nuclear Information System (INIS)

    1990-01-01

    1 - Description of program or function: AUS is a neutronics code system which may be used for calculations of a wide range of fission reactors, fusion blankets and other neutron applications. The present version, AUS98, has a nuclear cross section library based on ENDF/B-VI and includes modules which provide for reactor lattice calculations, one-dimensional transport calculations, multi-dimensional diffusion calculations, cell and whole reactor burnup calculations, and flexible editing of results. Calculations of multi-region resonance shielding, coupled neutron and photon transport, energy deposition, fission product inventory and neutron diffusion are combined within the one code system. The major changes from the previous release, AUS87, are the inclusion of a cross-section library based on ENDF/B-VI, the addition of the POW3D multi-dimensional diffusion module, the addition of the MICBURN module for controlling whole reactor burnup calculations, and changes to the system as a consequence of moving from IBM mainframe computers to UNIX workstations. 2 - Method of solution: AUS98 is a modular system in which the modules are complete programs linked by a path given in the input stream. A simple path is simply a sequence of modules, but the path is actually pre-processed and compiled using the Fortran 77 compiler. This provides for complex module linking if required. Some of the modules included in AUS98 are: MIRANDA Cross-section generation in a multi-region resonance subgroup calculation and preliminary group condensation. ANAUSN One-dimensional discrete ordinates calculation. ICPP Isotropic collision probability calculation in one dimension and for rod clusters. POW3D Multi-dimensional neutron diffusion calculation including feedback-free kinetics. AUSIDD One-dimensional diffusion calculation. EDITAR Reaction-rate editing and group collapsing following a transport calculation. CHAR Lattice and global burnup calculation. MICBURN Control of global burnup

    Full Text Available Sich selbst und den Anderen zu kennen setzt immer eine asymmetrische Position voraus. Die Person ist darauf gestellt, diese Leistung aus einer Position durchzuführen, die keine klare Orientierung ermöglicht und unsere derzeitigen Dispositionen beträchtlich übersteigt. Dem Menschen wird schließlich immer so viel gezeigt, damit er weiß und sieht, aber nicht so klar, damit er auch versteht. Die Art und Weise, in welcher eine Person mit sich selbst, mit dem Zorn, der Frustration, den Leidenschaften, der Sprache umgeht, vermittelt Informationen über individuelle Regungen der Seele, über Bewältigungsmechanismen. Man kann sie für eine gewisse Hilfestellung der Sprache selbst halten. Aber das Verständnis dieser Hilfestellung und des Ratschlags nur im Verhältnis zu sich selbst wäre zu eng. Wir wollen oder bekommen oft Ratschläge, die andere betreffen, aber wir müssen sie „aus sich selbst“ lösen. Und gerade aus sich selbst sollen wir fragen und sprechen. Im Augenblick, wenn diese Tiefe des Sprechens und Hörens erreicht wird, eröffnet sich die Möglichkeit, mit sich selbst und mit dem Anderen zu sein. Es ist jedoch zugleich ein Augenblick des Kampfes, der sich am Hintergrund des Gehörten konstituiert, das am Anfang oft als etwas Unverständliches erscheint oder das durch Vorstellungen und Schmerzen gestört wird. Die Antwort auf diesen Kampf ist die Kunst der Unterscheidung.

    In the AUS neutronics code system, the burnup module CHAR solves the nuclide depletion equations by an analytic technique in a number of spatial zones. CHAR is usually used as one component of a lattice burnup calculation but contains features which also make it suitable for some global burnup calculations. BURNMAC is a simple accounting module based on the assumption that cross sections for a rector zone depend only on irradiation. BURNMAC is used as one component of a global calculation in which burnup is achieved by interpolation in the cross sections produced from a previous lattice calculation

    For the application of our method for the sequential extraction of heavy metals from microsamples presented in part 1 (`Sequentielle Schwermetallextraktion von Mikroproben` - `Sequential Extraction of Heavy Metals from Micro Samples`) an investigation was carried out to evaluate airborne dust fallout and street sediments at two urban sites where different heavy metal immission rates occur due to traffic influence. In the street sediments the total concentrations of zinc, copper and lead was three to fivefold higher in the silt and clay fraction (<63 {mu}m) than in the particle size fraction (<1,12 mm), but showed nearly the same mobilisation behaviour. The dust samples showed equal mobilisation behaviour as the street sediments for copper and lead, while zinc was considerably more mobile in the dust samples: In extraction steps I-IV (I: mobile fraction; II: easily deliverable fraction; III: fraction bound to manganese oxides; IV: fraction bound organic to matter) zinc, copper and lead in street sediments, as well as copper and lead in dust samples, were dissolved to 40-70%, whereas about 80% of zinc in the dust samples was already dissolved in extraction step I.

  4. EDITAR: a module for reaction rate editing and cross-section averaging within the AUS neutronics code system

    International Nuclear Information System (INIS)

    Robinson, G.S.

    1986-03-01

    The EDITAR module of the AUS neutronics code system edits one and two-dimensional flux data pools produced by other AUS modules to form reaction rates for materials and their constituent nuclides, and to average cross sections over space and energy. The module includes a Bsub(L) flux calculation for application to cell leakage. The STATUS data pool of the AUS system is used to enable the 'unsmearing' of fluxes and nuclide editing with minimal user input. The module distinguishes between neutron and photon groups, and printed reaction rates are formed accordingly. Bilinear weighting may be used to obtain material reactivity worths and to average cross sections. Bilinear weighting is at present restricted to diffusion theory leakage estimates made using mesh-average fluxes

    Full Text Available RESUMO Objetivo: identificar fatores associados à ausência de expectativa de suporte para o cuidado aos idosos da comunidade. Método: foram utilizados parte dos dados do estudo multicêntrico "Fragilidade em Idosos Brasileiros", pesquisa quantitativa, epidemiológica e transversal desenvolvida no período de 2008 a 2009. Foram realizadas análises de comparação e regressão dos dados de 671 idosos. Resultados: a avaliação da expectativa de suporte para o cuidado aos idosos mostrou-se um bom indicador de risco para ausência de expectativa de suporte em mulheres, idosos que residiam sozinhos e com percepção ruim da própria saúde. Conclusão: conclui-se que é preciso refletir sobre o sistema de suporte oferecido aos idosos no Brasil, visto que o perfil destes que estão em risco é cada vez maior na população. Ressalta-se também a importância da inserção de métodos subjetivos para avaliação da percepção dos idosos sobre suporte para o cuidado.

    The Herdorf sewage system is presented as an example of heat recovery from compressed air of the activation stage. Consumption of externally supplied fuel (heating oil) was minimised, and full-scale power generation from sewage gas provided additional income. The key element of the heat recovery system is the air cooler with a matched double-shell heat exchanger. Temperatures and water volumes on the heating water side can be varied in order to ensure optimum heat supply to the air cooler at any time. The heat is used in the internal heating system to heat up the raw sludge in the fermentation process. [German] Die Waermerueckgewinnung aus der Druckluft von Belebungsanlagen kann einen wesentlichen Beitrag zum Waermehaushalt von Klaeranlagen liefern, wie hier am Beispiel der Klaeranlage Herdorf erlaeutert wurde. Hierdurch konnte zum einen der Einsatz von Fremdbrennstoffen (Heizoel) auf ein Minimum reduziert und zum anderen konnten zusaetzliche Ertraege aus der vollstaendigen Verstromung des Faulgases erzielt werden. Kernstueck der Waermerueckgewinnungsanlage bildet der Luftkuehler und der darauf abgestimmte Doppelmantelrohr-Waermeuebertrager. Von wesentlicher Bedeutung ist hierbei, dass auf der Heizkreiswasserseite mit variablen Heizwassermengen und korrespondierenden Temperaturen gefahren werden kann, um zu jedem Zeitpunkt die optimale Waerme durch den Luftkuehler bedarfsorientiert abgreifen zu koennen. Die Waerme dient zur Einspeisung in das Betriebs-Heizungssystem und damit zur Rohschlamm-Aufheizung im Faulungsprozess. (orig.)

    Excepting nuclear power, there are just two strategies to reduce global warming, i.e. either by saving energy or by using renewables, supported by public funding and guaranteed rates. The options of solar, wind, and hydroelectric power are limited in our climate and their potential is nearly completely exploited in some regions already. Biomass is an interesting option. Its introduction should be speeded up as it takes about 50 - 60 years for a new technology to be fully accepted. [German] Soll der Treibhauseffekt eingedaemmt werden, ohne in grossem Umfang auf Kernenergie zurueckzugreifen, bleiben nur zwei Moeglichkeiten: Energiesparen und verstaerkter Einsatz regenerativer Energiequellen. Finanzielle Foerderung aus oeffentlichen Mitteln und Garantiepreise bei der Stromerzeugung sollen den Weg gangbar machen. Sonne, Wind und Wasser eignen sich leider hierzulande nur begrenzt, teilweise ist ihr Potenzial schon weitgehend ausgeschoepft. Eine wichtige Ergaenzung des Angebots duerfte deshalb die Biomasse sein. Letztlich ist sie eine Speicherform von Sonnenenergie: Durch Photosynthese erzeugen Pflanzen aus Kohlendioxid und Wasser ihre eigenen Energietraeger, die Kohlenhydrate. Weil beim Verbrennen nur das aufgenommene Kohlendioxid wieder frei wird, zeigt die energetische Nutzung von Biomasse eine weitgehend ausgeglichene Klimabilanz. Doch Eile ist geboten. Die Nutzung von Kohle und Erdoel benoetigte 50 bis 60 Jahre, um sich zu etablieren; Experten halten das fuer einen typischen Zeitraum (den auch die Kernenergie noch nicht durchschritten hat). Sich erneuernde Energiequellen stehen noch am Anfang dieser Einfuehrungsphase. (orig.)

    The Audi AG is one of the worldwide leading car manufacturers of the premium class. One of the main aims of the technical development department at Audi is the use of novel and innovative materials. The Audi AG has intensively worked on the development and introduction of ceramic brake discs for several car types. These brake discs are made of a short carbon fiber reinforced silicon carbide ceramic, a so called CMC-material (ceramic matrix composite). This material is produced in a very complex process by silicon melt infiltration of carbon preforms. The advantages of these innovative and powerful brake discs out of C/SiC-ceramic are the low weight and thus the reduction of the unsprung rotating masses, the low wear rate during completed service life, the temperature and fading stability and the corrosion resistance. The complete braking system and its periphery had to be reengineered and adjusted because of the specific material properties. (Abstract Copyright [2007], Wiley Periodicals, Inc.)

Der Facettenreichtum der Aufsatzthemen entspricht dem im Titelkompositum „Unrechtserfahrungen“ ausgedrückten Spannungsverhältnis: Zum einen wird anhand von konkret erlebten Einzelschicksalen und von Darstellungen in der Literatur die Erfahrung von Ungerechtigkeit und Unrecht problematisiert. Zum anderen wird die rechtliche Begrifflichkeit genauer untersucht. Die Autorinnen kommen aus den Bereichen Philologie, Rechts- und Geschichtswissenschaft. Entsprechend bietet der Band eine vielfältige und insgesamt ergiebige Gesamtschau auf die Unrechtserfahrungen von Frauen in Vergangenheit und Gegenwart.This collected volume of eight essays tackles the experience of injustice specific to women. It was born out of an interdisciplinary colloquium during the winter semester of 2004/2005 at the Cornelia Goethe Center for Women’s Studies and the Study of Gender Relations (CGC. The richly varied themes of the essays correspond to the tension expressed in the composite word in the title “unjust-experience”: For one, the volume problematizes the experience of inequality and injustice through individual concrete experience and through literary presentations. In addition, it examines legal terminology in detail. The authors come from the wide-ranging areas of philology, law, and history. Accordingly, the volume offers a diverse and altogether rich overview of women’s experiences of injustice in the past and the present.

    The ATP binding cassette (ABC) transporter Aus1 is expressed under anaerobic growth conditions at the plasma membrane of the yeast Saccharomyces cerevisiae and is required for sterol uptake. These observations suggest that Aus1 promotes the translocation of sterols across membranes, but the precise transport mechanism has yet to be identified. In this study, an extraction and purification procedure was developed to characterize the Aus1 transporter. The detergent-solubilized protein was able to bind and hydrolyze ATP. Mutagenesis of the conserved lysine to methionine in the Walker A motif abolished ATP hydrolysis. Likewise, ATP hydrolysis was inhibited by classical inhibitors of ABC transporters. Upon reconstitution into proteoliposomes, the ATPase activity of Aus1 was specifically stimulated by phosphatidylserine (PS) in a stereoselective manner. We also found that Aus1-dependent sterol uptake, but not Aus1 expression and trafficking to the plasma membrane, was affected by changes in cellular PS levels. These results suggest a direct interaction between Aus1 and PS that is critical for the activity of the transporter.

    Full Text Available Das Institut für die Geschichte der deutschen Juden in Hamburg führt im Rahmen des Projekts "NS-Raubgut in der Bibliothek des IGdJ" umfangreiche Recherchen in seinen Buchbeständen durch. Die Untersuchung fügt sich in die Reihe von Forschungsvorhaben, die in der Folge der "Washingtoner Konferenz über Vermögenswerte aus der Zeit des Holocaust" (1998 und der ein Jahr später verabschiedeten "Erklärung der Bundesregierung, der Länder und der kommunalen Spitzenverbände zur Auffindung und zur Rückgabe NS-verfolgungsbedingt entzogenen Kulturgutes, insbesondere aus jüdischem Besitz" in diversen deutschen Bibliotheken, Museen, Archiven und anderen kulturellen Einrichtungen durchgeführt werden. Zurzeit befinden sich in der Bibliothek des IGdJ rund 50.000 Bände. Im Grunde ist bei allen Werken, die vor 1945 erschienen sind, eine Provenienz aus NS-Raub- bzw. NS-Beutegutbeständen möglich. Eine systematische Erfassung und Bearbeitung dieses rund 6.000 bis 9.000 Bände umfassenden Bestandes ist bislang nicht erfolgt. Da die Institutsbibliothek als jüdische Sammlung konzipiert und aufgebaut wurde, verstärkt sich diese Vermutung. Weil das Institut erst 1966 gegründet wurde, handelt es sich wahrscheinlich um "NS-Raubgut aus zweiter Hand“. Eine weitere Aufgabenstellung ergibt sich aus der Tatsache, dass in den Anfangsjahren der Bibliothek keine Zugangsjournale geführt wurden. Somit können in vielen Fällen nur die Bücher selbst Hinweise auf ihre Herkunft geben, weshalb als erste Maßnahme die eingehende Buchautopsie anhand des Zettelkatalogs durchgeführt wird. Der systematischen Suche nach NS-verfolgungsbedingt entzogenem Kulturgut folgt die Dokumentation und Bekanntgabe der Ergebnisse mit dem Ziel der Restitution an die Vorbesitzer oder deren Erben.

    The EU is planning to drop the threshold value for nickel in drinking water down to 20 {mu}g/l (present German threshold value: 50 {mu}g/l). Since ICP-MS-screenings of spot checks of water cookers were striking with respect to nickel, emissions of electrical water cookers have been investigated systematically within this study. As a result, water cookers with open heating coils are emitting relevant amounts of nickel into the water while it is brought to the boil. Investigation of eight preused water cookers with open heating coils revealed that the boiled water contained more than 50 {mu}g Ni/l in one case, more than 20 {mu}g Ni/l in two cases and, between 10 and 20 {mu}g Ni/l in two more cases, respectively. Removing of the lime by the aid of citric acid is increasing the nickel concentrations by a factor of up to 50 (max. 640 {mu}g/l). A new device was checked in a long-term test. During standard use with tapwater, Ni concentrations fall below the detection limit of 5 {mu}g Ni/l (120 cooking events). However, after removing of the lime, 5 times of cooking were necessary in order to diminish the Ni concentrations below the limit of 20 {mu}g/l. In the case of dionized water Ni concentrations below the limit of 20 {mu}g/l. In the case of deionized water Ni concentrations remained between 94 und 190 {mu}g/l. Health risk assessment: The intake of nickel with beverages made from hot water out of these cookers is in the range of 26 {mu}g/day. Considering an alltogether dietary nickel intake of 130-170 (900) {mu}g/day, this is not beyond the scope. However, according to the fact that nickel allergies (dermatitis) are very frequent (up to 13% of the population), this source should be limited or closed. (orig.) [Deutsch] Aus Anlass der geplanten Absenkung des Trinkwassergrenzwertes fuer Nickel auf 20 {mu}g/l sowie aufgrund von Auffaelligkeiten bei Stichprobenuntersuchungen wurde das Nickel-Emissionsverhalten von elektrischen Wassererhitzern betrachtet.

    Doleski, Oliver D.

    Die traditionelle Energieversorgung befindet sich in einer Zäsur. Das seit Jahrzehnten bewährte und stabile Geschäftsmodell einer zuverlässig planbaren, zentralen Energieerzeugung mit anschließender unidirektionaler Verteilung geriet spätestens seit der Energiewende des Jahres 2011 immer mehr unter Druck. Angesichts fortschreitender Digitalisierung und Dezentralisierung einerseits und gestiegener Erwartungshaltung der Kunden gegenüber "ihrem" Versorger andererseits sieht sich die Energiebranche heute einem epochalen Transformationsprozess gegenübergestellt. Bei diesem entwickeln sich aus den monopolistischen Versorgern des 19. und 20. Jahrhunderts (Utility 1.0), über die liberalisierten Energieversorgungsunternehmen (Utility 2.0) und Energiedienstleistungsunternehmen (Utility 3.0) heutiger Prägung, die digitalen Energiedienstleistungsunternehmen (Utility 4.0) von morgen. Oliver D. Doleski beschränkt sich in seinem Beitrag nicht auf die reine Beschreibung dieses Veränderungsprozesses an sich. Vielmehr werden darüber hinaus sowohl die mit dieser Entwicklung verbundenen übergeordneten Ziele als auch die wesentlichen Anforderungen an erfolgreiche Utilities 4.0 skizziert. Das Kapitel endet mit einem prägnanten Überblick profitabler Betätigungsfelder, die zur Sicherung der ökonomischen Zukunft von Energiekonzernen, Regionalversorgern und Stadtwerken beitragen können.

    In Germany, households account for about 30 percent of the total end use energy consumption. In fact, if heating and water heating are taken into account, the total amounts to more than 80 percent. This shows the necessity of making heating more energy-efficient and ecological. Heat pumps are an interesting solution. The contribution investigates their efficiency in real conditions, both in new and older buildings, and also goes into the possibility of optimization during installation, control and operation. The contribution is based on the long-term heat pump monitoring projects of Fraunhofer Institut fuer Solare Energiesysteme ISE of Freiburg. [German] In den deutschen Haushalten werden rund 30 % der Endenergie verbraucht. Obwohl der Bedarf fuer die Heizung oftmals unterschaetzt wird, entfallen in den Haushalten auf die Bereiche Raumwaerme und Warmwasser tatsaechlich mehr als 80 % des Energieverbrauches. Angesichts des fortschreitenden Klimawandels sowie der Ressourcenknappheit ist es dringend notwendig, die notwendige Heizenergie moeglichst effizient und oekologisch bereitzustellen. Die Waermepumpentechnologie ist in der Lage diesen Anforderungen gerecht zu werden. Wie effizient allerdings sind die Waermepumpenanlagen unter realen Bedingungen sowohl bei Neubauten als auch bei Bestandsgebaeuden?

    Rice is a dominant food crop of Bangladesh accounting about 75 percent of agricultural land use for rice cultivation and currently Bangladesh is the world's fourth largest rice producing country. Rice provides about two-third of total calorie supply and about one-half of the agricultural GDP and one-sixth of the national income in Bangladesh. Aus is one of the main rice varieties in Bangladesh. Crop production, especially rice, the main food staple, is the most susceptible to climate change and variability. Any change in climate will, thus, increase uncertainty regarding rice production as climate is major cause year-to-year variability in rice productivity. This paper shows the application of remote sensing data for estimating Aus rice yield in Bangladesh using official statistics of rice yield with real time acquired satellite data from Advanced Very High Resolution Radiometer (AVHRR) sensor and Principal Component Regression (PCR) method was used to construct a model. The simulated result was compared with official agricultural statistics showing that the error of estimation of Aus rice yield was less than 10%. Remote sensing, therefore, is a valuable tool for estimating crop yields well in advance of harvest, and at a low cost.

    The high-resolution computed tomography (HRCT) technique is an essential component in diagnosing interstitial lung disease (ILD) as it provides important and specialized information and a much greater accuracy than chest X-rays. It contributes to a narrowing down of the differential diagnoses and is also important for planning further invasive investigations, e.g. bronchoscopy, bronchoalveolar lavage, transbronchial lung biopsy and surgical lung biopsy, if needed. An accurate diagnosis of ILD is based on a multidisciplinary discussion involving pulmonologists, radiologists and pathologists experienced in the diagnosis of ILD. The therapy approaches of five different entities of ILD are shown as examples. In hypersensitivity pneumonitis the mainstay of treatment is complete avoidance of exposure to the provoking antigen. In cryptogenic organizing pneumonia most patients recover with corticosteroid therapy with prednisolone over a period of 6 months to 1 year. In cases of sarcoidosis therapy depends on organ involvement and functional impairment but there is no durable benefit to routine treatment of patients with acute pulmonary sarcoidosis, even among those with stage II or III chest radiographs. In general, patients with severe or progressive disease will require treatment. In idiopathic pulmonary fibrosis (IPF) a confident radiological diagnosis of definitive usual interstitial pneumonia (UIP) obviates the need for surgical lung biopsy. Other etiologies of a HRCT pattern of UIP, such as domestic and occupational environmental exposure, connective tissue disease and drug toxicity must be ruled out. In IPF antifibrotic therapy with pirfenidone (approval since 2011) or the triple tyrosine kinase inhibitor nintendanib (pending approval in 2015) can reduce disease progression but therapy with acetylcysteine alone or in combination with prednisolone and azathioprine failed to meet efficacy endpoints.

    In 1993, the U.S.A. and the CIS signed Start 2 (the Strategic Arms Reduction Treaty) in which they committed themselves the reduce their nuclear weapon arsenals to a fraction of that of 1991. For forty-five years the antagonism between the superpowers had been a dominating factor in world history, determining large areas of social life. When Start 2 will have been completed in 2003, some 200 t of weapon grade plutonium and some 2000 t of highly enriched uranium (Heu) will arise from dismantling nuclear weapons. In the absence of the ideological ballast of the debate about Communism versus Capitalism of the past few decades there is a chance of the grave worldwide problem of safe disposal and utilization of this former nuclear weapon material being solved. Under the heading of `swords turned into plowshares`, plutonium and uranium could be used for peaceful electricity generation. (orig.) [Deutsch] 1993 unterzeichneten die USA und GUS das Start-2-Abkommen (Strategic Arms Reduction Treaty), in dem sie sich zur Verringerung der Anzahl ihrer Nuklearwaffen auf einen Bruchteil des Bestandes von 1991 verpflichten. 45 Jahre lang stellte die Auseinandersetzung der Supermaechte einen dominierenden Faktor der Weltpolitik dar und bestimmte weite Teile des gesellschaftlichen Lebens. Mit der geplanten Erfuellung von Start 2 im Jahr 2003 werden ca. 200 t waffengraediges Plutonium und ca. 2000 t highly enriched uranium (Heu) aus der Demontage der Kernwaffen anfallen. Ohne den ideologischen Ballast der vergangenen jahrezehntelangen Auseinandersetzung zwischen `Kommunismus` und `Kapitalismus` besteht die Chance, das gravierende weltweite Problem der sicheren Entsorgung und Verwertung dieses ehemaligen Kernwaffenmaterials zu loesen. Unter dem Motto `Schwerter zu Pflugscharen` koennte das Plutonium und Uran zur friedlichen Elektrizitaetserzeugung genutzt werden. (orig.)

    The Technical University of Ilmenau, the company Verbundwerkstoff- und Kunststoffanwendungstechnik Schoenbrunn, the Institute for Aerospace and Light-weight construction of Dresden University with its approved testing facilities for plastics and the Institute for Construction Engineering in Berlin and several other institutions co-operated since 1996 in developing a concept for a series of long-term heat storage tanks up to 6,000 cubic metres storage volume made of plastic (GFK components) with a combined thermal insulation. A model tank (sandwich body with proportional thermal insulation layer and selected mixed laminates) with a volume of 1.5 cubic metres was built and installed in November 1996. The tank has been continuously operated at various test levels. The experiment proves the longevity of the materials used. (orig.) [Deutsch] In Zusammenarbeit der TU Ilmenau mit der Fa.

    Full Text Available O presente estudo buscou conhecer, por meio de uma abordagem qualitativa, quais as possíveis razões para a ausência paterna na vida dos filhos após o rompimento conjugal. Para tanto, foram entrevistados pais que participaram do serviço de mediação familiar e tiveram acordo homologado judicialmente em um Núcleo de Práticas Judiciárias Gratuitas. A pesquisa foi realizada utilizando a técnica de entrevistas semidirigidas de questões abertas, e os resultados analisados por meio da análise de conteúdo temática. Os pais relataram terem se sentido vítimas de um golpe - o golpe da barriga - que teve por objetivo mantêlos em um relacionamento em vias de dissolução. Assim, apresentaram dificuldades em estabelecer um vínculo afetivo com esse filho, visto que amá-lo seria assumir a efetividade de tal golpe. Ademais, foram identificadas semelhanças na história familiar dos participantes que envolviam a paternidade, as quais, por não terem sido problematizadas, não se tornaram objeto de reflexão, o que levou à repetição. Por fim, entende-se que o estudo aponta a importância do cuidado com relação aos efeitos da dissolução conjugal no que tange ao exercício dos papéis parentais, em especial, à paternidade.

    In 1996 the two large heat storage tanks in Hamburg-Bramfeld (4,750 cubic metres) and Friedrichshafen-Wiggenhausen (12,000 cubic metres) were built out of concrete with an inner stainless steel lining. This was a big step towards economic efficiency. The research project ``Tight sealing of pit water storage tanks made out of pre-stressed concrete`` was launched by the BMBF in order to show that the concrete construction will not only bear loads but also ensure sealing. Building costs for underground hot water storage tanks could then be reduced by at least 25%. The first results of this research project are presented. The paper also contains recommendations for the further development of heat storage tanks built with pre-stressed concrete. (orig.)

Mit dem Bau dieser beiden Grossspeicher konnte ein richtungsweisender Schritt hin zur Wirtschaftlichkeit gemacht werden, wie man es in Studien vor 15 Jahren nicht fuer moeglich hielt. Mit dem BMBF - Forschungsvorhaben `Dichte Heisswasser - Waermespeicher aus Hochleistungsbeton` soll gezeigt werden, dass das Betontragwerk nicht nur Lasten abtragen sondern auch die Funktion der Abdichtung uebernehmen kann. Damit sollen die Baukosten fuer unterirdische Heisswasser-Waermespeicher um mindestens 25% gesenkt werden.

    It is becoming generally accepted that world-class mineral deposits have a footprint on a scale of the lithosphere. For this reason, Australia has embarked on the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) to map the conductivity of the mid to lower crust and the lithospheric mantle. AusLAMP is a collaborative project between Geoscience Australia, State and Territory Geological Surveys and Universities. The project aims to collect long-period magnetotelluric data across the Australian continent on a nominal 0.5x0.5° ( 55x55 km) grid. To date, more than 450 sites have been acquired including all sites for the state of Victoria, two-thirds of sites in South Australia and Tasmania, and approximately 25 stations in Western Australia. Progress is ramping up with acquisition to turn to the state of New South Wales, the remainder of South Australia and also acquisition in northern Australia. To support this increasing acquisition activity, additional instruments have been purchased to add to those already in Australia. 3D inversion results are now available for AusLAMP Victoria. In collaboration with the National Computational Infrastructure (NCI), the 3D ModEM codes were optimised for use on the NCI's supercomputer, speeding up large-scale inversions by an order of magnitude. The results of these inversions indicate anomalously conductive lithospheric mantle associated with the central region of Victoria which contains significant mineral deposits and prospectivity, and also anomalous resistive lithosphere associated with the southern extension of the dynamically supported Australian Alps and the Newer Volcanics Province. Modelled conductivities are also consistent with mantle xenolith data from central Victoria. Within the crust, the dominant trend of the data is along elongate north-eastern corridors of conductive material. These results shed new questions on the geological history of this region and the lithospheric architecture of the

    Material stream analysis can serve as a basis for decisions on which materials should be kept in circulation, and in what quantity, and which materials it is better to remove from the recycling system and dispose of as waste. Wastes destined for disposal are mostly transferred to waste treatment plants and landfills. The role of thermal treatment as part of the disposal system is to destroy or decompose organic pollutants contained in the waste, concentrate and remove inorganic pollutants, make the heat arising during the treatment process available for use as energy, and make the greatest possible physical use of the treatment residues. The present paper reviews the current regulations for the promotion of recycling and investigates selected material streams and the fate of these materials. In connection with the residue quality of household waste incineration slag as a thermal waste treatment product it also considers the influence of waste management measures on wastes destined for disposal. [Deutsch] Stoffstrombetrachtungen koennen als Grundlage fuer Entscheidungen dienen, welche Stoffe in welchem Umfang im Kreislauf verbleiben oder wieder integriert werden sollten und welche besser als Abfall zur Beseitigung aus dem Kreislaufsystem auszuschleusen sind. Fuer Abfaelle zur Beseitigung wird diese Aufgabe i.d.R. von thermischen Abfallbehandlungsanlagen und Deponien uebernommen. Im Rahmen der Entsorgung kommt der thermischen Behandlung dabei die Aufgabe zu, die im Abfall zur Beseitigung enthaltenen organischen Schadstoffe zu zerstoeren oder abzubauen, anorganische Schadstoffe aufzukonzentrieren und auszuschleusen, die bei dem Behandlungsprozess entstehende Waerme einer weitgehenden Energienutzung zuzufuehren und die Rueckstaende aus der Behandlung so weit wie moeglich stofflich zu verwerten.

Objetivo: Analisar a quantidade (duração e intensidade de atividade física em seus diferentes domínios (trabalho, deslocamento, atividade doméstica e tempo livre como discriminador da ausência de hipertensão arterial em adultos do sexo masculino. Métodos: Estudo transversal realizado na cidade de Lauro de Freitas, Bahia, Brasil com amostra constituída por 220 indivíduos do sexo masculino com idade superior a 18 anos. Foram construídas diversas curvas Receiver Operating Characteristic (ROC e comparadas às áreas sobre as mesmas entre a quantidade de atividade física em seus diferentes domínios e a ausência de hipertensão arterial. Verificou-se também a sensibilidade e especificidade para a quantidade de atividade física necessária para prevenção de hipertensão arterial. Foi utilizado o intervalo de confiança a 95%. Resultados: Entre os diferentes domínios de atividade física analisados encontrou-se maior significância estatística nas áreas sob a curva ROC para a atividade física no trabalho e no tempo livre. A caminhada não foi boa discriminadora para a ausência de hipertensão arterial em nenhum dos domínios analisados. Observou-se também que 180 min/semana de atividade física moderada, acumulada nos diferentes domínios foi o melhor ponto de corte para discriminar a ausência de hipertensão arterial. Conclusão: A prática da atividade física, principalmente de intensidade moderada, com duração de pelo menos 180 min/semana deve ser sugerida para indivíduos do sexo masculino visando contribuir para a prevenção da hipertensão arterial.

Verwertung oder Nicht-Verwertung der Reststoffe aus der Kohleverbrennung kann zu einer Differenz bei den Stromerzeugungskosten von 15% fuehren. Die Parameter Brennstoffe, Feuerungstechnik, Rauchgasreinigungstechnik, Produktverwertung sind je nach Standort individuell zu bewerten. Das Spannungsfeld liegt zwischen hochwertigen Brennstoffen und Produkten, fuer die in der Anlagentechnik auch entsprechende Investitionen erforderlich sind (z.B. Staubfeuerung mit Kalkstein- oder Ammoniakalischer Waesche) oder einfacheren Verfahren mit zum Teil geringeren Investitionskosten (z.B. Rauchgasreinigung mittels Trocken- oder Halbtrockenverfahren).

    Full Text Available To date, the historiography of reparations after World War I has a predominant focus on cash. The article proposes considering non-cash contributions a constitutive part of the Treaty of Versailles and investigating their impact on the post-World War I order. Contemporary debates on the supply of building materials to northern France illustrate the expectations on the German side that were raised by the promise of such deliveries in kind: Policymakers hoped that deliveries in kind would reduce the overall sum of reparations; smart entrepreneurs hoped for lucrative business, for instance from the sale of prefabricated houses; and trade unions saw new prospects for German workers and German building materials. Though deliveries in kind to the areas undergoing reconstruction in northern France were in practice small, the related debates disclose new perspectives on the post-war history. This example serves as a case in point for the potential of applying theoretical considerations about the social dimension of materiality to the context of the Treaty of Versailles and its consequences. Die Geschichtsschreibung der Reparationen nach dem Ersten Weltkrieg handelt bislang vor allem von Geld. Dieser Aufsatz plädiert dafür, auch die Sachlieferungen als einen wesentlichen Bestandteil des Versailler Vertrags zu interpretieren. Exemplarisch wird erprobt, wie sich theoretische Überlegungen zur sozialen Dimension von Dingen auf die Geschichte des Versailler Vertrags und seiner Folgen anwenden lassen. Anhand der zeitgenössischen Diskussionen über geplante Lieferungen von Baumaterial nach Nordfrankreich lässt sich nachvollziehen, dass man auf deutscher Seite mit diesen Reparationsleistungen durchaus Erwartungen verknüpfte: Aus Sicht der Politik sollten Sachlieferungen dazu beitragen, die Gesamtsumme der Reparationen zu mindern. Findige Unternehmen hofften schon 1919 auf einträgliche Geschäfte, etwa durch den Verkauf von Fertighäusern. Auch die

Die Ursache einer nicht-traumatischen intrazerebralen Blutung ist in ueber 60% der Faelle eine Hypertonie, weniger haeufig die Folgen des Alkoholismus, Gefaessfehlbildungen oder die Amyloidangiopathie.

    The B 2 Σ - - X 2 Π 3/2 (0,0) bands of a cold molecular beam sample of gold monoxide, AuO, and gold monosulfide, AuS, have been recorded at high resolution both field free and in the presence of a static electric field. The observed electric field induced splittings and shifts were analyzed to produce permanent electric dipole moments, μ→ el , of 2.94±0.06 D and 2.22±0.05 D for the X 2 Π 3/2 (v = 0) states of AuO and AuS, respectively. A molecular orbital correlation diagram is used to rationalize the trend in ground state μ→ el values for AuX (X = F, Cl, O, and S) molecules. The experimentally determined μ→ el are compared to those computed at the coupled-cluster singles and doubles (CCSD) level augmented with a perturbative inclusion of triple excitations (CCSD(T)) level of theory.

    Since the mid-eighties, Messrs. Max Aicher Umwelttechnik GmbH at Hammerau, Germany have been investigating sewage sludge pyrolysis. Laboratory experiments and semi-industrial investigations led to the construction of a combined sludge drying and conversion plant (``Aicher sludge recycling process``), in which the organic sludge fraction is converted into recyclable or combustible oils. Carbon is obtained as a by-product in solid form as conversion coke which can be utilized. Apart from sewage sludge, also industrial sludges with high organic fractions can be processed, e.g. sludges and sewage sludges from petroleum processing. (orig.)

    CuMed beinhaltet interaktive, fallbasierte Kleingruppenseminare, Fertigkeiten- und Kommunikationstraining, Problem-orientiertes Lernen, studentische Fallbearbeitungen und -präsentationen sowie Unterricht am Krankenbett. Die Dozenten werden didaktisch geschult. Das vorangegangene traditionelle Curriculum basierte dagegen auf Vorlesungen und lediglich zwei Wochenstunden praktischen Unterrichts am Krankenbett. Ziel: Die vorliegende Arbeit analysiert den Beitrag didaktischer Merkmale des traditionellen und Reformcurriculums sowie der aktiven Mitarbeit der Studierenden zum Lernerfolg aus Sicht der Studierenden. Methode: Differenzierte studentische Evaluationen der chirurgischen Lehrveranstaltungen zwischen 1999 and 2008 wurden mittels Korrelations- und Regressionsanalysen untersucht.Ergebnisse: Das Engagement der Dozenten, ihre Fähigkeit, Interesse zu wecken und Kompliziertes verständlich zu erklären, der Beitrag des Unterrichts zum Lernzuwachs, die Unterrichtsqualität und besonders die geförderte Mitarbeit wurden in HeiCuMed signifikant besser bewertet als im traditionellen Curriculum. Die Abhängigkeit des subjektiven Lernzuwachses von der didaktischen Qualität war hingegen in beiden Curricula gleich. Die geförderte studentische Mitarbeit erwies sich als wichtig für den subjektiven Lernzuwachs in den Seminaren und Praktika von HeiCuMed und für die evaluierte Qualität der Praktika aber nicht für den Lernzuwachs im traditionellen Curriculum. Schlussfolgerung: Die Ergebnisse stehen im Einklang mit psychologisch-pädagogischen Erkenntnissen, dass integrative Lehrmethoden mehr zum Lehr- und Lernerfolg beitragen als der passive Wissenstransfer durch die traditionelle Vorlesung, und belegen die wichtige Bedeutung der didaktischen Kompetenz für den Lehrerfolg.

  8. Risk energy transition. Ways out of the impasse; Risiko Energiewende. Wege aus der Sackgasse

    The exit of the use of nuclear energy in Germany, it was decided in the summer of 2011 in a rush. Now it is becoming obvious that there is no realistic plan for the conversion of energy supply in the envisaged deadline of ten years. For the conversion of our entire power supply and therefore our economy the period is too short. It lacks a robust empirical reason that have to deal with the issues of security of supply, the affordability, the impact on economic development and social justice. Thus, this treansition threatens to fail at their contradictions. Konrad Kleinknecht tries in his book, to name the problems and to find answers. For him, arise the following questions: What are our opportunity to replace with wind and solar power to replace a part of the power supply? What power sources provide secured capacity? Can we dispense with coal-fired plants? Do we need new power lines? How power may be stored? How real is the risk of blackouts in windless nights? Will the power prices continue to rise? Can be avoided the major risks of the energy transition with a fundamental reform of the Renewable Energies Act (EEG)? The power supply must serve the common good and benefit the industrial site Germany. A blackout would be a disaster for the whole country, it must be avoided at all events. How can we manage this, the author present in his evocative book. [German] Der Ausstieg aus der Nutzung der Kernenergie in Deutschland wurde im Sommer 2011 im Eiltempo beschlossen. Jetzt zeigt sich, dass es keinen realistischen Plan fuer den Umbau der Energieversorgung in der vorgesehenen Frist von zehn Jahren gibt. Fuer die Umstellung unserer gesamten Stromversorgung und damit unserer Wirtschaft ist der Zeitraum zu kurz. Es fehlt eine belastbare empirische Begruendung, die Fragen der Versorgungssicherheit, der Finanzierbarkeit, der Auswirkungen auf die wirtschaftliche Entwicklung und die soziale Gerechtigkeit behandeln muesste. Somit droht diese Wende an ihren Widerspruechen zu

    Abstract Atypia/follicular lesion of undetermined significance (AUS/FLUS) is a new category in the Bethesda System for Reporting Thyroid Cytopathology (BSRTC) for which repeat fine-needle aspiration cytology (FNAC) is recommended. The aim of this study was to identify specific ultrasonography and clinical predictors of malignancy in a subset of thyroid nodules associated with cytology diagnoses of AUS/FLUS. Between January 2011 and December 2102, 5440 patients underwent thyroid surgery at our institution. Of these, 213 patients were diagnosed AUS/FLUS at the preoperative cytopathology diagnosis. The frequency of FNAC and ultrasonography images was compared between patients with cancerous and benign tumors based on their final pathology. Of the 213 patients, 158 (74.2%) were diagnosed with thyroid carcinoma in their final pathology reports. In univariate and multivariate analyses, the frequency of FNAC was not significantly correlated with the cancer diagnosis. Hypoechogenicity (odds ratio 2.521, P = 0.007) and microcalcification (odds ratio 3.247, P = 0.005) were statistically correlated with cancer risk. Although AUS/FLUS in cytopathology is recommended for repeating FNAC in BSRTC, we proposed that thyroid nodules with ultrasonography findings that suggest the possibility of cancer should undergo thyroidectomy with diagnostic intent.

    If one would like to get the heating load of a building by using peripheral generated electrical energy from photovoltaics or small wind power, one must deal with both the specific building, as well as the heating load, the heating temperature limit and the differentiation of specific heating period for the building. Here, a ground source heat pump with an intelligent energy storage system seems to be the first choice. [German] Moechte man mit dezentral erzeugter elektrischer Energie aus Photovoltaik oder Kleinst-Windkraft die Heizlast eines Gebaeudes besorgen, muss man sich sowohl mit dem spezifischen Gebaeude, als auch mit der Heizlast, der Heizgrenztemperatur und der Differenzierung der spezifischen Heizperiode fuer das Gebaeude auseinandersetzen. Dabei scheint eine erdgekoppelte Waermepumpe mit einem intelligenten Speichersystem die erste Wahl.

    MIRANDA is the cross-section generation module of the AUS neutronics code system used to prepare multigroup cross-section data which are pertinent to a particular study from a general purpose multigroup library of cross sections. Libraries have been prepared from ENDF/B which are suitable for thermal and fast fission reactors and for fusion blanket studies. The libraries include temperature dependent data, resonance cross sections represented by subgroup parameters and may contain photon as well as neutron data. The MIRANDA module includes a multiregion resonance calculation in slab, cylinder or cluster geometry, a homogeneous B L flux solution, and a group condensation facility. This report documents the modifications to an earlier version of MIRANDA and provides a complete user's manual

    On March 2, 2004, the Heinz Maier-Leibnitz research neutron source (FRM-II) generated neutrons for the first time. This marked the most important step on the way to using FRM-II for scientific purposes. On this occasion, this unique research facility in the world was dedicated in a ceremony attended by approximately 1000 representatives of politics, industry, and science. The keynote speaker, Federal Minister of the Interior Otto Schily; Bavarian Minister President Edmund Stoiber; Professor Claus Weyrich (Member of the Executive Board of Siemens AG); Dr. Thomas Goppel (Bavarian State Minister for Science, Research, and Arts); Professor Wolfgang A. Herman (President of the Technical University of Munich); Hannelore Gabor (2nd Mayor of the host municipality of Garching); and Professor Winfried Petry (Scientific Director of FRM-II) underlined the great importance of FRM-II for science, research, medicine, and technology. FRM-II will not only fill the 'neutron gap', but create extremely brilliant working conditions thanks to its considerably higher neutron flux compared to that of its predecessor, the legendary Atomic Egg. After the first conceptual design studies starting in 1980, the ground breaking ceremony in August 1996, and the third partial permit issued at Easter of 2003, a unique tool is now available for modern science and for medical and technical applications.

    Zusammenarbeit in Teams ist eine wichtige Voraussetzung für qualitativ hochwertige Versorgung im Gesundheitswesen. In diesem Zusammenhang spielen auch Führungskompetenzen von Ärztinnen und Ärzten im klinischen Alltag eine wichtige Rolle. Bisher wurde die Entwicklung von Führungskompetenzen in medizinischen Curricula in der Aus- und Weiterbildung von Ärztinnen und Ärzten jedoch kaum systematisch abgebildet. Die Entwicklung adäquater und effektiver Trainingsmethoden für die Vermittlung von Führungskompetenzen ist daher wünschenswert. Ziel: Das Review soll vorliegende Ergebnisse der Literatur zu Trainings von Führungskompetenzen in der Medizin zusammenfassen und integrieren, um zukünftige Forschung und Trainingsentwicklung anzuregen. Methode: Die Datenbanken PubMED, ERIC, PsycArticles, PsycINFO, PSYNDEX und dem Academic search complete durch EBSCOhost wurden auf Deutsch und Englisch nach Trainings von Führungskompetenzen in der Medizin durchsucht. Relevante Artikel wurden identifiziert und die Studienergebnisse hinsichtlich des zugrundeliegenden Führungsverständnisses, der Zielgruppe und Teilnehmeranzahl, der zeitlichen Ressourcen, sowie der Inhalte und Methoden des Trainings, des Evaluationsdesigns und der berichteten Trainingseffekte zusammengefasst. Ergebnisse: Auf acht Studien trafen alle Einschluss- und kein Ausschlusskriterium zu. Die Trainings selbst sowie die thematisierten Führungskompetenzen differenzieren jedoch stark voneinander. Die Trainingsdesigns beinhalten im Schwerpunkt die theoretische Auseinandersetzung mit dem Thema Führung sowie die Diskussion von Fallstudien aus der Praxis. Die Dauer der Trainings reicht von mehrstündigen bis hin zu mehrjährigen Veranstaltungen. Die selbst eingeschätzte Reaktion der Teilnehmer auf alle Trainings war positiv; es fand jedoch bisher keine systematische Überprüfung des Trainingserfolgs in Bezug auf konkrete Verhaltensänderungen der Teilnehmer statt.Schlussfolgerungen: Es bedarf weiterer Forschung, um die

    The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) is an Australian initiative to map the Australian continental lithosphere using magnetotelluric (MT) stations to obtain a resistivity model of the subsurface. It is a joint project between Geoscience Australia, state surveys, and Universities. We present new MT 3D inversion results of the largest coherent array of the AusLAMP MT deployments to date covering two-thirds of South Australia, funded largely by the Geological Survey of South Australia with additional funding by Geoscience Australia and The University of Adelaide. The model extends across the South Australian Gawler Craton, including the Eucla Basin to the west of the craton and the Flinders Ranges and Curnamona Province to the east. The MT array covers parts of the Australian lithosphere, which has been largely unexplored with seismic tomography methods and provide a unique insight into the tectonic evolution of the continent. We incorporate 284 long-period (10s-10,000s) MT stations separated roughly every half degree latitude and longitude across an area spanning 1200 km x 800 km, south of latitude -28.5 degrees and from longitude 129 degrees to 141 degrees. We invert 24 discrete periods of the impedance tenor between 7 s and 13,000 s, and 22 different periods of the tipper data between 7s-8000 s period. The results show a heterogeneous lower crust and mantle lithosphere with a primarily resistive mantle (>1000 Ωm) lithosphere in the central and western part of the Gawler Craton and Eucla Domain. The model shows a generally NS oriented electric LAB offset from deeper cratonic lithosphere in the west to a shallow lithosphere along the eastern margin of the Gawler Craton extending further east towards the Proterozoic and Phanerozoic eastern part of Australia. The lower crust is generally resistive with elongated lower crustal conductivity anomalies, which are associated with major translithospheric shear zones likely existent

    Due to high costs core recovery in many wells is strongly restricted. To determine thermal conductivity in these cases measurements on cuttings are necessary, since in situ measurements are expensive and protracted, too. Therefore cores from three hydrogeothermal wells of the north-east part of the German sedimentary basin were grinded to compare the results of measurements on cuttings with known values of thermal conductivity from the original cores. By a suitable model of the two-phase-system cuttings-water it is possible to calculate the thermal conductivity of the rock-matrix. On the basis of this value and a suitable rock-model an average thermal conductivity for the water saturated rock can be estimated. Certainly all influences of the texture (anisotropy, grain bond) and of the characteristics of the porespace (porosity, internal surface, saturation, permeability) are lost with measurements on cuttings. Therefore for the different systems cuttings-water and rock-porefluid as well as for different rock types different models are necessary. (orig.) [Deutsch] In vielen Bohrungen werden aus Kostengruenden keine Kerne gezogen. Fuer die Ermittlung der Waermeleitfaehigkeit koennen deshalb nur in-situ-Messungen, die ebenfalls zeit- und kostenintensiv sind, oder Messungen am Bohrklein herangezogen werden. Es wurden daher Kerne aus drei Hydrogeothermalbohrungen des nordostdeutschen Beckens aufgemahlen, um so vergleichende Messungen am `Bohrklein` aus Kernen mit bekannter Waermeleitfaehigkeit durzhzufuehren. Durch eine geeignete Modellvorstellung des Zwei-Phasen-Systems Bohrklein/Wasser laesst sich die Waermeleitfaehigkeit der Gesteinsmatrix bestimmen und aus dieser durch ein Gesteinsmodell auch eine mittlere Waermeleitfaehigkeit des wassergesaettigten Festgesteins berechnen. Klar ist, dass bei Messungen am Bohrklein Einfluesse, die durch Gefuege (Anisotropie, Kornbindung) und Porenraumeigenschaften (Porositaet, Saettigung, Permeabilitaet) hervorgerufen werden

    Biogas contains after the production of up to 55% CO{sub 2}. In order to use biogas as a fuel or to feed it into the natural gas network, it must be purified before. Adsorption and scrubbing processes are primarily used technically. Membrane processes offer the advantage of continuous operation and a simple modular and flexible system design, which imply relatively low investment costs and low energy needs. Moreover, membrane systems can be started up and shut down quickly without any problems. Ceramic membranes are characterised by high stability (thermal, chemical, mechanical) and very high flows in comparison to polymeric membranes. [German] Biogas enthaelt nach der Erzeugung bis zu 55 % CO{sub 2}. Um Biogas als Kraftstoff zu nutzen oder in das Erdgasnetz einspeisen zu koennen, muss es zuvor gereinigt werden.

Membranverfahren bieten den Vorteil eines kontinuierlichen Betriebes sowie einer einfachen, modularen und flexiblen Anlagenkonzeption, die vergleichsweise niedrige Investitionskosten und einen geringen Energiebedarf bedeuten. Darueber hinaus koennen Membrananlagen schnell an- und abgefahren werden und voellig ohne Probleme abgeschaltet werden. Keramische Membranen zeichnen sich gegenueber Polymermembranen durch hohe Stabilitaet (thermisch, chemisch, mechanisch) und sehr hohe Fluesse aus.

A working group comprising representatives of the insular works and the propane-air producers for peak demand have critically examined the quality requirements in the field of product, operation, application and management of the gas supply on the basis of a well-defined performance commission. The evaluation of the enquiry at the member plants showed that, especially concerning the gas quality, network management, operational security and the organisational procedures, a demand for an efficient quality management exists. For a long-term execution of the service commission a certification according to ISO 9000-Series is recommended. (orig.) [Deutsch] In den Energieversorgungsunternehmen bestehen erhebliche Bedenken ueber die Nuetzlichkeit von Qualitaetssicherungssystemen. Deren richtige Anwendung schafft jedoch Kostentransparenz, steigert die Wirtschaftlichkeit und foerdert die Kundenzufriedenheit. Eine Arbeitsgruppe aus Vertretern der Inselwerke und der Propan-Luft-Spitzendeckung hat sich bei definiertem Leistungsauftrag mit den Qualitaetsanforderungen in den Bereichen Produkt, Betrieb, Anwendung und Management der Gasversorgung auseinandergesetzt. Die Auswertung der Umfrage bei den Mitgliedwerken zeigte, dass besonders bei der Gasqualitaet, der Netzbewirtschaftung, der Betriebssicherheit und der betrieblichen Ablauforganisation ein Bedarf an effizienter Qualitaetsbewirtschaftung besteht. Zur langfristigen Erfuellung des Dienstleistungsauftrages empfiehlt sich die Zertifizierung nach der ISO-9000er-Reihe. (orig.)

    Coatings of cubic boron nitride (cBN), the second hardest of all known materials, were prepared using a sputter process. A new coating design, based on a special B-C-N layer system, allows to deposit thick (> 2 {mu}m) cBN films, however so far only on silicon substrates. The properties of the coatings are quite similar to those of bulk cBN. Promising experiments were performed with respect to a transfer of this application relevant layer system to cemented carbide and steel substrates. First measurements of the mechanical and tribological properties confirmed the outstanding properties and the high potential of such cBN based coating systems. (orig.) [German] Schichten aus kubischem Bornitrid (cBN), dem nach Diamant zweithaertesten aller bekannten Materialien, wurden mit einem Sputter-Prozess hergestellt. Ein neuartiger Schichtaufbau, der auf einem speziellen B-C-N-Schichtsystem basiert, ermoeglicht die Abscheidung von cBN-Schichten mit ueber 2 {mu}m Dicke, allerdings bisher nur auf Siliciumsubstraten. Die Eigenschaften der Schichten sind denen von massivem cBN sehr aehnlich. Es wurden vielversprechende Experimente zur Uebertragung dieses fuer Werkzeugbeschichtungen und vielfaeltige andere Anwendungen interessanten Schichtsystems auf Werkzeugsubstrate durchgefuehrt. Erste Untersuchungen der mechanisch-tribologischen Eigenschaften der auf Hartmetall- und Stahlsubstraten abgeschiedenen Schichten belegen das aussergewoehnlich hohe Potential der cBN-basierten Schichtsysteme.

    We examined the associations of objectively measured sedentary time and physical activity with continuous indexes of metabolic risk in Australian adults without known diabetes. An accelerometer was used to derive the percentage of monitoring time spent sedentary and in light-intensity and moderate-to-vigorous-intensity activity, as well as mean activity intensity, in 169 Australian Diabetes, Obesity and Lifestyle Study (AusDiab) participants (mean age 53.4 years). Associations with waist circumference, triglycerides, HDL cholesterol, resting blood pressure, fasting plasma glucose, and a clustered metabolic risk score were examined. Independent of time spent in moderate-to-vigorous-intensity activity, there were significant associations of sedentary time, light-intensity time, and mean activity intensity with waist circumference and clustered metabolic risk. Independent of waist circumference, moderate-to-vigorous-intensity activity time was significantly beneficially associated with triglycerides. These findings highlight the importance of decreasing sedentary time, as well as increasing time spent in physical activity, for metabolic health.

    Sedentary behaviors, particularly television viewing (TV) time, are associated with adverse health outcomes in adults, independent of physical activity levels. These associations are stronger and more consistent for women than for men. Multivariate regression models examined the sociodemographic correlates of 2 categories of TV time (≥ 2 hours/day and ≥ 4 hours/day); in a large, population-based sample of Australian adults (4950 men, 6001 women; mean age 48.1 years, range 25-91) who participated in the 1999/2000 Australian Diabetes, Obesity, and Lifestyle (AusDiab) study. Some 46% of men and 40% of women watched ≥ 2 hours TV/day; 9% and 6% respectively watched ≥ 4 hours/day. For both men and women, ≥ 2 hours TV/day was associated with less than tertiary education, living outside of state capital cities, and having no paid employment. For women, mid and older age (45-64 and 65+) were also significant correlates of ≥ 2 hours TV/day. Similar patterns of association were observed in those viewing ≥ 4 hours/day. Prolonged TV time is associated with indices of social disadvantage and older age. These findings can inform the understanding of potential contextual influences and guide preventive initiatives.

    Abstract Background: The TBscore, based on simple signs and symptoms, was introduced to predict unsuccessful outcome in tuberculosis patients on treatment. A recent inter-observer variation study showed profound variation in some variables. Further, some variables depend on a physician assessing...... them, making the score less applicable. The aim of the present study was to simplify the TBscore. Methods: Inter-observer variation assessment and exploratory factor analysis were combined to develop a simplified score, the TBscore II. To validate TBscore II we assessed the association between start...

  19. Der II. Hauptsatz der Wärmelehre

    Science.gov (United States)

    Heintze, Joachim

    Wir haben in (4.44) den II. Hauptsatz als empirische Tatsache folgendermaßen formuliert: (i) Wärmeenergie geht von selbst nur von einem wärmeren Körper auf einen kälteren über, niemals in der umgekehrten Richtung. Nun werden wir beweisen, dass sich aus diesem Prinzip folgende äquivalente Formulierungen für den II. Hauptsatz ableiten lassen: (ii) Es ist unmöglich, ein Perpetuum mobile zweiter Art zu bauen, d. h. eine Maschine, die fortlaufend Wärmeenergie vollständig in mechanische Arbeit umsetzen kann. Eine Wärmekraftmaschine, die einen Kreisprozess mit der höchsten Temperatur Tw und der niedrigsten Temperatur Tk durchläuft, hat höchstens den Carnotschen Wirkungsgrad c = (Tw - Tk)/Tw. Wenn in der Maschine nur reversible Prozesse ablaufen, die gesamte Wärmezufuhr bei der Temperatur Tw erfolgt und ausschließlich bei der Temperatur Tw gekühlt wird, ist ihr Wirkungsgrad = C. Es gibt keine Wärmekraftmaschine, die eine bessere Ausnutzung der Wärmeenergie ermöglicht. (iv) In jedem thermodynamischen System existiert die Zustandsgröße Entropie, definiert durch ihr Differential dS = (dQrev)/T . Entropie kann erzeugt, aber nicht vernichtet werden. Bei Zustandsänderungen, die in einem abgeschlossenen System ablaufen, nimmt die Entropie entweder zu (irreversible Prozesse), oder sie bleibt konstant (reversible Prozesse). Im Anschluss an (iii) werden wir zur Definition der thermodynamischen Temperatur und bei der Diskussion von (iv) zu einem tieferen Verständnis der Entropie gelangen. Es zeigt sich, dass die Entropie das eigentliche Bindeglied zwischen Mechanik und Wärmelehre darstellt. Am Ende des Kapitels werden wir einige Anwendungen des II. Hauptsatzes betrachten.

    Full Text Available Was bedeutet das Attribut „Quality-TV“ eigentlich für das Publikum? Nach welchen Kriterien beurteilen Zuschauerinnen und Zuschauer, ob eine Serie Qualitätsfernsehen ist oder nicht? Im Bereich der rezipientenorientierten Qualitätsforschung bezüglich Fernsehserien sind bislang fast ausschließlich qualitativ erhobene Modelle bedeutsam, am bekanntesten sicherlich die bereits 1996 von Robert J. Thompson vorgeschlagenen 12 Kriterien. Die vorliegende Untersuchung widmet sich nun der Frage, ob diese Qualitätskriterien tatsächlich die „richtigen“ sind. Sind sie für die Zuschauer/innen von Serien bedeutsam für die Einschätzung, ob ein Programm „Quality-TV“ ist oder nicht? Bislang fehlt eine empirische Fundierung der einzelnen Merkmale. Ebenso ungeklärt ist bislang, ob es eine Rangfolge dieser Merkmale gibt. Welche sind bedeutsamer, welche weniger wichtig für die Wahrnehmung einer Serie als Qualitätsprodukt? Die Studie hat Thompsons Vorschlag (unter Bezugnahme auf weitere Studien zum Thema (z.B. Cardwell 2007; Feuer 2007; Dreher 2010; Blanchett 2011; Kumpf 2011 operationalisiert und in einer standardisierten Befragung der Nutzer von 13 Onlineforen zu Qualitätsserien (n=1382 getestet. Auf Basis dieser Befragung kann statistisch nachgewiesen werden, welche Merkmale von den Zuschauer/innen als besonders wichtig angesehen werden und wie diese zu Qualitätsfaktoren zusammengefasst werden können, die das Phänomen „Quality-TV“ aus Zuschauersicht tatsächlich beschreiben können.

    The Y2K problem has many facets due mainly to two reasons: The extremely wide use of microcomputers, and the complexity of automation in modern industrial plants. For the past two years, Siemens AG has been checking the Y2K conformity of its products. The result of these investigations is this: All automation equipment, almost without exception, is in conformity with the year 2000 requirements as it works without the date function causing the errors. A few occasional malfunctions were discovered in older computer-supported operating and monitoring stations and in process computer applications. However, malfunctions are not going to cause failures of the system but only make its use more difficult. (orig.) [German] Ursache des Jahr-2000-Problems ist die Unfaehigkeit gewisser aelterer Software, das Jahresdatum 2000 beim Uebergang der letzten beiden Ziffern von '99' auf '00' richtig zu verarbeiten. Potenziell betroffen sind alle Geraete und Systeme, die in irgendeiner Form Rechner oder Mikrorechner enthalten. Das Jahr-2000-Problem ist sehr vielschichtig. Dies resultiert im Wesentlichen aus zwei Gruenden: Der extrem weiten Verbreitung von Mikrorechnern und der Komplexitaet der Automatisierung moderner Industrieanlagen. Die Siemens AG ueberprueft seit zwei Jahren die 2000-Jahr-Konformitaet ihrer Produkte. Ergebnis der Untersuchungen ist: Automatisierungsgeraete sind fast ausnahmslos Jahr-2000 konform, da sie ohne die fehlerverursachenden Datumsfunktionen auskommen. Vereinzelte Fehlfunktionen wurden in aelteren rechnergestuetzten Bedien- und Beobachtungssystemen sowie in Prozessrechneranwendungen gefunden. Fehlfunktionen fuehren jedoch meist nicht zum Versagen des Systems, sondern erschweren nur dessen Nutzung. In den sicherheitsrelevanten Bereichen der Kernkraftwerke werden ausschliesslich die vom Jahr-2000-Problem nicht betroffenen Automatisierungsgeraete eingesetzt. (orig.)

    Knittings based on ceramic filament yarns can be used to clean polluted air and exhaust gas efficiently up to temperatures of 1000 C. They provide interesting properties for the filtration of Diesel particles as well as for catalysis and adsorption of toxic gas components. The special knitting technology can handle any brittle fibers, producing elastic structures, which are thermochoc-resistent and can therefore even be used for preturbo applications. The first part of this paper, published in MTZ 56 (1995) 2 deals with the basic properties of this cleaning medium. This second part concentrates on Diesel particulate trop applications. These new trap and catalyst concepts are under development by Buck/Bondorf with TTM/Niederrohrdorf. Basic research is delegated to ETH Zuerich and Universitaet by Gillet/Edenkoben and, with focus on preturbo-applications by MTU/Friedrichshafen. (orig.) [Deutsch] Gestricke aus keramischen Endlosfasern sind bis zu Temperaturen um 1000 C fuer die Abluft- und Abgasreinigung einsetzbar. Sie eignen sich fuer die Filtration von Dieselpartikeln, insbesondere deren Feinstfraktionen ebenso wie fuer die Katalyse und fuer die Adsorption gasfoermiger Schadstoffkomponenten. Die Strukturen sind volumenelastisch, unempfindlich gegen Thermoschock und daher auch im motornahen Bereich risikoarm einsetzbar. In einem ersten Teilbeitrag in der Februarausgabe der MTZ wurden grundlegende Erkenntnisse dieses Abgasreinigungsmediums beschrieben. Der vorliegende zweite Teil beschreibt Anwendungen mit Schwerpunkt Dieselpartikelfilter. Diese neue Fasertechnik wird bei Buck, Bondorf, zusammen mit TTM, Niderrohrdorf, entwickelt.

Es wurde eine mittlere korporale Belastung mit Blei von 41,5 {mu}g/l Blut (95% K.I.: 39,6-43,6) und eine mittlere innere Exposition mit Cadmium von 0,417 {mu}g/gKr (95% K.I.: 0,390-0,447) festgestellt. Somit unterschied sich die innere Belastung mit Blei und Cadmium nicht oder nur geringfuegig von der der Allgemeinbevoelkerung. Von der gemessenen korporalen Belastung ging keine gesundheitliche Gefaehrdung aus. Frauen aus der schwermetallbelasteten Region Hettstedt hatten im Vergleich zu Frauen aus den beiden anderen Regionen keine erhoehten Blutbleikonzentrationen. Die Blutbleikonzentration, die v.a. die aktuelle Exposition gegenueber Blei reflektiert, wurde bei Frauen im 6. Lebensjahrzehnt von individuellen Verhaltensweisen wie dem Rauchen sowie von der Distanz des Wohngebietes zu den Hettstedter Huettengebieten beeinflusst. Ausserdem fuehrte eine erhoehte Bleikonzentration im Trinkwasser sowie die Freisetzung von Blei aus den Knochen nach der Menopause zu einer erhoehten Blutbleikonzentration. Im Vergleich zu Frauen aus den Kontrollregionen wiesen Frauen aus Hettstedt eine deutlich erhoehte Cadmiumexkretion mit dem Urin auf. Die Cadmiumkonzentration im Urin spiegelt v.a. die kumulative, lebenslange Exposition gegenueber Cadmium wider. (orig.)

    In the present study, the amount of polycyclic aromatic hydrocarbons (PAH) in contaminated soil material, which may be available for absorption in the gastrointestinal tract, is estimated by means of evaluating the PAH mobilization by synthetic gastric and intestinal juice in an in vitro test system. Five contaminated soil materials from a former landfill site are analysed in this gastrointestinal model for the PAH of the U.S.EPA-standard. For quantification, an HPLC method with reversed-phase chromatography and on line fluorescence detection is used. The PAH concentration of the contaminated soil materials ranged from 37 {mu}g/g up to 196 {mu}g/g in total. The mobilization of the PAH in the gastrointestinal model ranged from 0.3% up to 1.3% when gastrointestinal juice was used alone. In the presence of whole milk powder, however, the mobilization was enhanced to values from 10.8% up to 14.5%. Since the soil material was taken from different parts of the contaminated area, and since the mobilization of the PAH from the different materials shows only minor differences, the mobilization data evaluated may be considered as representative for the whole contaminated area. Compared to other contaminated soil materials, especially those from gas work areas or coke plants, the mobilization rate of PAH by the gastrointestinal model from the soil materials used in this study is low. The health risk caused, by ingestion of this soil material, as far as PAH are concerned, is actually smaller than the risk calculated from the total content of PAH of the contaminated soil. (orig.)

    The described processing technique consisting of topped thermal hydrolysis and downstream fermentation is particularly suitable for wet, low-structure organic waste. High turnover rates at short treatment times permit to minimize residues effectively, yield a fair amount of biogas and allow compact design because of low fermenter volumes, which has a positive impact on investment cost.

    Full Text Available The assumption this article is based on is that guilt is perhaps the most important theme in Alois Hotschnig’s writing. This article therefore aims at analyzing Hotschnig’s focus on the theme of guilt in his novels. Three examples of Hotschnig’s prose work serve as case studies: his debut Aus, and the two novels Leonardos Hände, and Ludwigs Zimmer. Since guilt seems to be a very important topic in the Austrian literary tradition, this article also tries to establish whether and how Hotschnig takes up this grand Austrian tradition of writing about guilt.

    Sedentary behaviour is associated with increased risk for all-cause and cardiovascular mortality. Plasma fibrinogen and C reactive protein (CRP)-key inflammatory and/or haemostatic markers-may contribute to this association; however, few studies have examined their relationships with sedentary behaviours. We examined associations of overall sitting and TV viewing time with fibrinogen and high-sensitivity CRP (hsCRP). Plasma fibrinogen and hsCRP were measured in 3086 Australian adults (mean age: 55±12 years) who participated in the 2004-2005 AusDiab (Australian Diabetes, Obesity and Lifestyle) study. Multiple linear regression analyses examined cross-sectional associations of self-reported overall sitting and TV viewing time (h/day) with plasma fibrinogen and hsCRP, adjusting for sociodemographic, behavioural and medical treatments and conditions as potential covariates. Overall sitting time and TV viewing time were positively associated with plasma fibrinogen (sitting: β: 0.02 g/L, 95% CI (0.01 to 0.02); TV time: 0.03 g/L (0.02 to 0.05)) and hsCRP (sitting: 2.4% (1.2% to 3.6%); TV time: 4.5% (1.7% to 7.4%)). Associations were independent of leisure-time physical activity, but after adjusting for waist circumference, they remained for fibrinogen, but for hsCRP were attenuated to the null. Interactions were observed for gender×TV (p=0.011) with fibrinogen (associations in women only) and for waist circumference×TV (p=0.084) with hsCRP (associations in low-risk only). Overall sitting time was positively associated with plasma fibrinogen and hsCRP in men and women; associations of TV viewing time with fibrinogen were observed in women only. Abdominal adiposity-mediated associations for hsCRP but not for fibrinogen. Prospective and intervention studies are needed to establish likely causality and elucidate potential mechanisms.

    The intraplate deformation of the north-south trending Neoproterozoic Ikara-Flinders Ranges in South Australia, Australia, draws interest due to its high heat flow, elevated seismicity and the presence of diamondiferous kimberlites and mineral deposits. To the west lies the highly prospective Archean-Paleoproterozoic Gawler Craton, boasting the world's largest IOCG-U deposit, Olympic Dam. The Paleo-Mesoproterozoic Curnamona Province lies to the east, thought to have once been connected to the Gawler Craton and host to the world-class Broken Hill Ag-Pb-Zn deposit. A total of 162 long-period (10 s - 10,000 s) magnetotelluric (MT) stations from the Australia-wide AusLAMP (Australian Lithospheric Architecture Magnetotelluric Project) dataset were used to image the electrical resistivity beneath the Ikara-Flinders Ranges and adjacent Curnamona Province. The most recent acquisition extends this survey region northward to an area predominantly covered with Paleo-Mesozoic sedimentary basins including the most significant on-shore oil and gas region in Australia, the Cooper Basin. The resultant model from 3D inversions using ModEM software shows a relatively resistive Ikara-Flinders Ranges, with two parallel arcuate conductors (the WNAC and ENAC) at 20 to 80 km depth in the Nackara Arc. These conductors correlate well with locations of diamondiferous kimberlites which suggests that the conductors may have derived from the ascent of carbon-rich kimberlite-hosting magma and volatiles up large lithospheric scale structures. The conductors appear to have no correlation with regions of intraplate seismicity within the Ikara-Flinders Ranges which may mean that enhanced pore fluid pressure is not the main cause for the seismicity as was recently proposed. A large conductor covering most of the Curnamona Province (the CC) extends over depths of 10-40 km. The Curnamona Province's most recent tectonothermal activity is from Delamerian reworking during the Cambrian at its margins but

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

Métodos: um total de 840 amostras de fala foi analisado neste estudo. As amostras foram julgadas por três juízas experientes por consenso quanto aos aspectos hipernasalidade e fricativa faríngea. Os julgamentos foram distribuídos em quatro grupos: G1: 255 amostras de fala julgadas como representativas de hipernasalidade; G2: 130 amostras julgadas como representativas do uso de fricativa faríngea e hipernasalidade; G3: 280 amostras julgadas como representativas de fala normal em falantes com história de fissura labiopalatina; G4: 175 amostras julgadas como representativas de fala normal em falantes sem história de fissura labiopalatina. Para análise dos dados foi utilizando o teste Kruskal-Wallis e quando houve diferença estatisticamente significante foi aplicado o teste Dunn's para comparar os grupos aos pares. Resultados: os julgamentos aferidos por consenso pelas três juízas permitiram a identificação de amostras representativas do uso de fricativa faríngea e da presença e ausência de hipernasalidade. Foram estabelecidos valores de nasalância (média e desvio padrão para cada grupo e observou-se que houve diferença estatisticamente significante entre os grupos com alteração de fala (G1 e G2 e aqueles sem alteração (G3 e G4. A diferença entre o grupo com hipernasalidade (G1 e o grupo com FF (G2 não foi significante. Conclusão: o uso de FF não influenciou significantemente os valores de nasalância para a amostra estudada.

    Full Text Available Ao observar a iconografia na obra impressa desses dois artistas de contextos diversos, é possível estabelecer uma aproximação. Ambos praticaram repetições e variações temáticas/cromáticas. Uma exposição ocorrida no Louisiana Museum of Modern Art (Dinamarca colocou lado a lado os dois artistas. O curador da exposição, Poul Erik Tøjner, afirma que ambos compartilham uma consciência retórica sobre os meios e fins da arte. A retórica de Munch, ancorada no Simbolismo, vai além da reiteração de um pensamento sobre o fantasma da ausência, muitas vezes materializado em mancha, sombra e duplo. Warhol, ao emergir nos anos 1960 em Nova York, escolheu a serigrafia - um meio utilizado na publicidade - para "pintar" os seus ícones - estrelas de Hollywood, quase todas de destino trágico. As suas imagens - Marilyns, cadeiras elétricas, latas de sopa Campbell, etc. - tematizam não a presença desses seres e objetos, e sim sua ausência.

    After implementation of the EU Internal Gas Market Directive in Germany, marketers from EU member states are increasingly interested in entering the German natural gas market. In addition to the legal and competition aspects arising analogous to the internal market in electrity, as e.g. third party access to pipelines, management of physical transactions and use-of-pipeline pricing, natural gas trading of suppliers from EU member states in the German market has to be reviewed also from the angle of section 3 of the EnWG (German act for reform of the energy industry law), in which provisions are set forth governing and defining the case of energy supply to third parties, marketers being obliged to apply for a licence. The legal requirements and the various aspects to be considered are explained in detail. (Orig./CB) [German] Nach Ablauf der Umsetzungsfrist der Gas-Binnenmarktrichtlinie interessieren sich nunmehr auch GVU aus anderen Mitgliedstaaten fuer Gaslieferungen an Abnehmer in der Bundesrepublik.

    The authors present a method developed at the Institute of Chemical Engineering and Steam Boiler Technology (IVD) of Stuttgart University for quasi-continuous online measurement of tar concentrations in gases from biomass gasification. The method is compared with other methods in terms of time requirements, accuracy, and cost: Gravimetry, wet chemical analysis, solid phase amino-adsorption (SPA), and online process gas chromatography. The measurements were carried out on the fluidized-bed combustion system of the IVD. Wood was gasified at 800 degrees centigrade with a fuel/air ratio of 0.25. The measured tar concentrations differed widely, i.e. between 0.8 and 6.8 g per cubic metre. (orig.)

Untersucht wurden dabei eine gravimetrische Methode, die nasschemische Bestimmung, das Solid-Phase-Amino Adsorptionsverfahren (SPA), sowie die Online Analyse mittels Prozess-Gaschromatograph. Die Messungen wurden an der Wirbelschichtvergasungsanlage des IVD durchgefuehrt. Vergast wurde Holz bei 800 C und einer Luftzahl von 0.25.

    entwickelten Transfertechnik fuer monokristalline Siliciumfilme, die auf der Bildung einer Trennschicht mittels elektrochemischer Aetzverfahren beruht. Dieses Verfahren wurde seit einer Anpassung des Arbeitsplanes im Jahr 2000 im Vorhaben verfolgt und konnte die damaligen hohen Erwartungen sogar noch uebertreffen. Es wird in einem Anschlussvorhaben weiterentwickelt, um unter anderem belastbare Fakten zu Fragen der industriellen Anwendbarkeit zu sammeln. Die direkte Herstellung effizienter polykristalliner Siliciumsolarzellen auf Glassubstraten bei Temperaturen zwischen 400 und 600 C erwies sich als aeusserst schwierig und vermutlich unmoeglich. Zum ersten Mal konnte eine umfassende Analyse der grundsaetzlichen Begrenzungen fuer pn-Solarzellen aus Silicium mit Korngroessen im Bereich von (1-100) {mu}m vorgelegt werden. Der Durchgang von Korngrenzen durch den pn-Uebergang begrenzt in diesem Korngroessenbereich die erreichbare Ausgangsspannung prinzipiell auf inakzeptabel niedrige Werte. Die thermokatalytische Abscheidung (hot-wire CVD) nanokristalliner Si-Filme (nc-Si) fuer den Einsatz in gestapelten, mikromorphen Solarzellen konnte dahingehend optimiert werden, dass Schichten mit ausschliesslicher <110>-Textur erzielt wurden. Solche Schichten zeigen stabile elektronische Eigenschaften; Veraenderungen durch die Aufnahme von atmosphaerischem Sauerstoff, Wasser usw. koennen damit vermieden werden. Der Einsatz in Solarzellen scheint jedoch der geringen Abscheiderate wegen wenig sinnvoll. Hier zeigte sich, dass Schichten guter elektronischer Qualitaet in hot-wire CVD aehnlich niedrige Abscheideraten erfordern wie in plasmagestuetzten Verfahren. Weitere Ergebnisse in den Bereichen Ionenunterstuetzte Abscheidung (IAD), Laserkristallisation und Si-Hetero-Solarzellen koennen als spin-off fuer andere Anwendungen genutzt werden. (orig.)

    This report describes a computer program package that aids in assessing the impact of floods on risk from nuclear power plants. The package consists of two distinct computer programs: ESP and NOAH. The ESP program improves the efficiency of a flood analysis by screening accident sequences and identifying accident sequences that are potentially significant contributors to risk in the event of a flood. Input to ESP includes accident sequences from an existing risk assessment and flood screening criteria. The NOAH program provides detailed qualitative analysis of the plant systems identified by ESP. NOAH performs a qualitative flood simulation of the fault tree

    Full Text Available Currently, a shift from classical flood protection as engineering task towards integrated flood risk management concepts can be observed. In this context, a more consequent consideration of extreme events which exceed the design event of flood protection structures and failure scenarios such as dike breaches have to be investigated. Therefore, this study aims to enhance existing methods for hazard and risk assessment for extreme events and is divided into three parts. In the first part, a regionalization approach for flood peak discharges was further developed and substantiated, especially regarding recurrence intervals of 200 to 10 000 years and a large number of small ungauged catchments. Model comparisons show that more confidence in such flood estimates for ungauged areas and very long recurrence intervals may be given as implied by statistical analysis alone. The hydraulic simulation in the second part is oriented towards hazard mapping and risk analyses covering the whole spectrum of relevant flood events. As the hydrodynamic simulation is directly coupled with a GIS, the results can be easily processed as local inundation depths for spatial risk analyses. For this, a new GIS-based software tool was developed, being presented in the third part, which enables estimations of the direct flood damage to single buildings or areas based on different established stage-damage functions. Furthermore, a new multifactorial approach for damage estimation is presented, aiming at the improvement of damage estimation on local scale by considering factors like building quality, contamination and precautionary measures. The methods and results from this study form the base for comprehensive risk analyses and flood management strategies.

    Full Text Available In Italy, the commemorative culture regarding World War II has a rather multi-faceted appearance. This seems to be the consequence of the variety of military and civil groups involved in the Italian front as well as in the political post-war scene. The case of the fallen combatants (partigiani who belonged to the Resistance is emblematic. Despite any historical truth, their commemoration has been considered as a left-wing issue. Following the dynamics of the political debate, fallen partisans were remembered in a strongly familiar dimension (1950s, as heroic rebels (1960s-1980s or as epic founders of the Italian Republic (partially up the 1990s. This case study of the Central Italian province of Ancona shows how both the sepulchral and the commemorative culture of the members of the Resistenza is closely linked to this general development.

  10. Theoretical and experimental studies on the improvement of the time structure of the extracted electron beam from the stretcher ring ELSA; Theoretische und experimentelle Untersuchungen zur Verbesserung der Zeitstruktur des extrahierten Elektronenstrahls aus dem Stretcherring ELSA

    The Electron Stretcher Accelerator ELSA of Bonn University is the first electron-pulse-stretcher-ring in the GeV-range. It delivers an external electron beam in the energy range from 500 MeV to 3.5 GeV, with a current between 10 pA and 100 nA, depending on the demands of the experiments. A synchrotron is used to preaccelerate the electrons to energies between 500 MeV and 1.8 GeV. In this energy-range, ELSA is used in the pure stretcher-mode, whereas for higher energies it is used as a post accelerator. For beam extraction, a third-integer resonance, driven by sextupoles, is applied. The problems, delimiting the duty-factor of the extracted beam in the pure stretcher-mode, have been investigated and solved. In this mode, duty-factors - measured by coincidence methods - of up to 55% have been reached, which are of the order of the theoretical limit for the applied extraction method of about 60%. (orig.) [Deutsch] Ziel dieser Arbeit war es, die Phaenomene, die das Tastverhaeltnis des aus ELSA extrahierten Strahles beeinflussen, zu verstehen. Aus dem gewonnenen Verstaendnis heraus sollten Massnahmen getroffen werden, um das Tastverhaeltnis zu verbessern. Die Effekte, die ein gutes Tastverhaeltnis in der Vergangenheit verhindert haben, waren in der Hauptsache ein Stromrippel in den Netzgeraeten der Hauptmagnete sowie die Extraktion aus dem Synchrotron, die nur eine schlechte Fuellung von ELSA erlaubte. Der Rippel wurde durch den Einbau von Filtern in die Netzgeraete behoben. Bei den gegenwaertigen Extraktionszeiten von 20 msec spielt der Rippel nur noch eine geringe Rolle. Die Extraktion aus dem Synchrotron wurde modifiziert, so dass ohne Beschaffung neuer Komponenten eine Verbesserung der ELSA-Fuellung von 40% auf maximal 75% moeglich wurde. Durch eine Reihe von Massnahmen konnte der Wert des Tastverhaeltnisses von 6%-7% kurz nach der Inbetriebnahme auf heute 50%-55% gesteigert werden. Die Extraktion kann durch ein einfaches Modell beschrieben werden, dass alle

    Full Text Available Die Psychotherapeutin Michaela Huber hat auf knapp sechshundert Seiten ein gleichermaßen sensibles wie engagiertes „Standardwerk“ der Traumabehandlung geschrieben. Die Zuerkennung dieser Auszeichnung durch das Österreichische Netzwerk für Traumatherapie erfolgt zu Recht. Vom Standpunkt der so genannten empathischen Abstinenz aus vermittelt Huber auf anspruchsvolle, doch durchweg gut verständliche Weise, wie ein Trauma entsteht und wirkt, was man sich unter einer Traumabehandlung vorzustellen hat und worauf es ankommt, wenn die komplexe Dynamik zwischen Täter, Täterin, Opfern und Überlebenden zwischenmenschlicher Gewalt durchbrochen werden soll. Geschrieben hat sie für Betroffene und deren Angehörige, für Fachkolleginnen und -kollegen sowie für alle in irgendeiner Form an der Thematik Interessierten. All jenen, die sich etwa aus philosophischer, kultur-, literatur-, geschichtswissenschaftlicher und/oder geschlechtertheoretischer Perspektive mit dem Phänomen des Traumas beschäftigen, seien die in zwei Teilbänden versammelten Erfahrungen, Erkenntnisse und Ergebnisse der jüngsten Psychotraumatologie als Grundlagenlektüre nahe gelegt.The psychotherapist Michela Huber has written an almost 600 page “standard work” of trauma therapy that is as sensitive as it is engaged. The deserved distinction was awarded by the Austrian Network for Trauma Therapy. From the standpoint of so-called empathetic abstinence, Huber explains in a demanding yet understandable manner how trauma occurs and what its effects are, what one can expect of trauma therapy and what needs to take place if the complex dynamic of interpersonal violence between perpetrator, victim, and survivor is to be broken. She wrote for victims and their families, for colleagues, and for all those who are interested in the subject in any form. The two-volume collection of the experiences, incite, and results of the most recent psychotraumatology is a strongly recommended read

    The organ- and tumour-related specific characteristics of prostate carcinoma (PC) are presented in an overview under various aspects. It is the key for understanding pathological changes, including PC, to consider the subdivision of the prostate into anatomically and functionally distinguishable zones, especially the transitional zone (TZ) and the peripheral zone (PZ). The pseudoneoplastic hyperplasia of the TZ, combined with inflammatory consequences and age-related changes, forms a differential diagnostic challenge to both clinico-radiological diagnosis and macroscopic and microscopic examination. High-degree prostatic intra-epithelial neoplasia (PIN III) and atypical adenomatous hyperplasia (AAH) are presented as precursor lesions of PC with varying significance and assessment. Moreover, there are discussed the following characteristic features of PC: localisation types, focality, volume, progression, double-graduation according to Gleason, tumour stage, and prognosis. The most important prognosis factors of PC (category I) include the categories of the TNM system, such as stage, surgical marginal situation, degree and also the preoperative PSA level as a (poor) substitute for the tumour volume. Potential prognosis parameters (category II) show the tumour volume and the DNS ploidy, while there continues to exist a large number of non-established parameters (category III). The prognostic validity of the pathological examinations depends, on the one hand, on the tissue extent (needle biopsy, transurethral resection (TURP), so-called simple prostatectomy, radical prostatectomy (RPE)) and the prostate zones covered. On the other hand, the prognostic certainty also depends on the tumour-adequate macroscopic and microscopic assessment of an RPE that can only be a partial or complete handling in transversal large-area sections.

    2002-01-01

    Full Text Available Este ensaio é uma introdução à obra de Cristopher Boorse, filósofo da medicina que criou, nos anos 70, a Teoria Bioestatística da Saúde (TBS. Em primeiro lugar, examinamos o argumento e a estrutura da TBS, destacando seus elementos epistemológicos fundamentais e principalmente as justificativas lógicas e teóricas de sua definição da saúde como ausência de doença. Em segundo lugar, discutimos as numerosas críticas recebidas por Boorse em duas décadas de circulação dos seus textos, buscando estabelecer a pertinência e atualidade dessas críticas. Em seguida, identificamos problemas e pontos fortes da teoria boorseana, retomando as principais críticas dirigidas ao autor, bem como suas tentativas de resposta. Por fim, levantamos algumas questões que podem propiciar uma continuidade e um enriquecimento do debate em torno do conceito de saúde a fim de explorar sua aplicabilidade para uma teoria geral da saúde-doença-cuidado, cada vez mais necessária neste momento em que se pretende uma maior articulação entre abordagens biológicas e ecossociais dos fenômenos da saúde e da doença.

    In the present work a concept of probabilistic safety-analysis for the dismantling of slender concrete-structures by tilting is developed. Based on requirements, that define a regular dismantling process, models describing characteristic limit-states of the building are derived. The connection of these limit-states allows rating the whole process. Uncertainties in the model-input are caught by using stochastic variables. Uncertainties in the model itself are caught by using inferior and superior modelling. With the help of two concluding examples it is shown, how the obtained probability of failure can be used to enhance objectiveness of safety-considerations. The numeric simulation is based on a Monte-Carlo method. (orig.)

    In the ultrasonic testing of large, thick-walled components made of ductile iron partial acoustic paths of several meters are needed. Considered here are cylindrical components such as the body of CASTOR containers with diameters 2-3 m, a height of up to 6 m and a wall thickness of 500 mm. So far, an automated technique for this is not available, therefore such components are checked in a complex and lengthy process by manual ultrasonic testing. The development and design of the testing by means of simulations and the realization as a mobile testing device are topics of this paper. Measurements on a reference body with test reflectors in different depths are presented and discussed. [German] Bei der Ultraschall-Pruefung von grossen, dickwandigen Bauteilen aus Gusseisen mit Kugelgraphit werden teilweise Schallwege von mehreren Metern noetig. Betrachtet werden hier zylinderfoermige Bauteile, wie die Koerper von CASTOR-Behaeltern, mit Durchmessern zwischen 2 und 3 m, einer Hoehe von bis zu 6 m und Wanddicken von ca. 500 mm. Bisher ist eine automatisierte Technik hierfuer nicht verfuegbar, daher werden derartige Bauteile in einem aufwaendigen und langwierigen Prozess mittels manueller Schallung geprueft. Zur Erhoehung der Nachweissicherheit und zur Steigerung der Effizienz im Pruefablauf sollen nun senkrecht zur Achse des zylinderfoermigen Bauteils liegende unzulaessige Anzeigen im gesamten Mantelvolumen durch eine teilautomatisierte Pruefung ausgeschlossen werden. Die Entwicklung und Auslegung der Prueftechnik mittels Simulationen und die Realisierung als mobile Pruefvorrichtung sind Themen dieses Beitrags. Messungen an einem Referenzkoerper mit Testreflektoren in verschiedenen Tiefen werden vorgestellt und diskutiert.

    The present paper reports a study of photoinduced crystallization in thermally evaporated Se 92.7 S 7.3 films. The photoinduced crystallization was achieved by shining white light (from 25 mW/cm 2 tungsten lamp) at room temperature for different exposure times up to 5.184 Ms. The analysis of X-ray diffraction (XRD) patterns indicated that the grain size (D), the strain (ζ) and the dislocation density (δ) are photoaging dependent. The capacitance-voltage data confirmed that the relative permittivity of the films is equal to ∼10.31. Room temperature current density voltage characteristics of Au/Se 92.7 S 7.3 /Au films showed Ohmic conduction in the lower voltage range ∼<1 V, and space charge limited conductivity (SCLC) in the relatively high-voltage range. The SCLC was controlled by an exponential distribution of traps above the valence band. The temperature dependence of the current density in accordance with the theory for the exponential trap distributions allowed the calculation of some essential parameters such as; trap concentration, characteristic temperature, and the trap density

    Full Text Available The study focuses on Bronislav Wellek, Adolph Donath, Camill Hoffmann, Oskar Wiener and Otto Hauser and their translations and articles on modern Czech literature published in the German journal Aus fremden Zungen (1891–1910. This fortnightly established by Joseph Kürschner dealt exclusively with foreign literature. Its openness to all kinds of literary currents and little-known minor literatures was unique within the system of German literary journals. A comparison indicates the key role played by mediators. The primary requirement for their activity was multilingualism, and it turns out that in the case of all the figures under consideration, language did not necessarily have the nationally symbolic significance ascribed by politics, and their identity basically did not depend on their use of one language or another. The progress and success of this mediation was not just decided by the literary standard of the translation, but all five translators were concerned to improve the standard of translation, as well as to change the approach to translation in general. The choice of text and its succeeded publication was determined by the involvement of the mediators in the Czech and German literary context. Hence Bronislav Wellek focused primarily on translations and interpretations of poetry by Jaroslav Vrchlický and J. S. Machar, whom he knew personally and who also introduced him to their own literary and intellectual circles. It was thanks to Vrchlický that he printed his translations in Eduard Albert’s anthologies Poesie aus Böhmen (1893–1895. Machar was responsible for other translations, e.g. Hilbert’s drama Vina, which Hermann Bahr was to help promote in the German-language sphere. Between 1896 and 1898, Adolph Donath attempted to build up his position as mediator between the Moderní revue circle and some representatives of Viennese modernism (e.g. Karl Kraus, Peter Altenberg and Felix Rappaport.

    Mine water treatment is costly, difficult, and requires extensive surface installations. The author explains the development of geochemical ('active') barriers of low-cost materials. The materials investigated were industrial residues (red sludge, fly ash, tinder residues, porous concrete residues), natural materials (bark, zeolite, bentonite, hydroxyl apatite), and commercial products (GEH, Ratio Pur MF-S). Investigations focused on density, specific surface, grain size, and acid neutralization capacity. In the final stage, experiments were made on heavy metal removal from a model water. [German] Einen grossen Anteil an der Schwermetallbelastung in Fluessen haben toxische Abwaesser aus Bergbaugebieten (Grubenwaesser). Die Moeglichkeit der Behandlung sind sehr aufwendig, kostenintensiv und nur 'ueber Tage' durchfuehrbar. Die vorliegende Arbeit erlaeutert die Behandlung von Grubenwaessern mit geochemischen ('aktiven') Barrieren. Es werden aktive Barrieren entwickelt, die in einen Schacht eingebracht werden koennen, um eine Schwermetallausbreitung zu unterbinden. In diesem Zusammenhang werden kostenguenstige Materialien untersucht, die Schadstoffe durch chemische und/oder physikalische Mechanismen aus Wasser entfernen koennen. Untersucht wurden industrielle Reststoffe (Rotschlamm, Flugasche, Zunderrueckstaende, Porenbetonabfall), natuerliche Materialien (Baumrinde, Zeolith, Bentonit, Hydroxylapatit) und kommerzielle Produkte (GEH, Ratio Pur MF-S). Die Materialien werden hinsichtlich der Dichte, der spezifischen Oberflaeche, der Korngroesse und der Saeureneutralisationskapazitaet charakterisiert. Anschliessend wurden Versuche zur Schwermetallentfernung aus einem Modellwasser durchgefuehrt. (orig.)

Embora associada a consequências negativas, pois muitas patologias físicas e mentais são desencadeadas por exposição crônica a estressores, esta resposta é indispensável para sobrevivencia do indivíduo e é extremamente adaptativa quando ativada de forma aguda. Na parte I desta revisão foram abordados os conceitos de homestase e alostase e os sistemas fisiológicos ativados durante a resposta ao estresse. Na parte II serão discutidos fatores que modulam a resposta ao estresse tais como sexo, temperamento, períodos críticos do desenvolvimento e a presença ou ausência de suporte social. A interação entre os fatores genéticos e ambientais gera os perfis da resposta psicofisiológica que caracterizam os fenótipos de susceptibilidade e resiliência frente aos estressores e sua relação com uma patologia mental cada vez mais presente na sociedade moderna, o transtorno de estresse pós-traumático.

    Full Text Available There is a growing recognition of the dangers of electoral violence. Yet, the theoretical foundation for systematic research and for adequate policy is still underdeveloped. This article aims to develop the theoretical understandings of strategies to manage and prevent electoral violence. This is accomplished by integrating research conducted within the two academic discourses on democratization and conflict management and also by drawing on the experiences from the conflict-ridden province KwaZulu-Natal in South Africa. The five strategies identified are monitoring, mediation, legal measures, law enforcement and self-regulating practices. In the article, the functions and mechanisms of the strategies are discussed. In addition, we analyse the limitations and usefulness of each of the strategies in turn and also provide suggestions on how to improve electoral security.Gewaltsame Auseinandersetzungen bei Wahlen werden zunehmend als Gefahr erkannt. Dennoch sind die theoretischen Grundlagen systematischer Forschungen zu diesem Phänomen, die zu angemessenen politischen Handlungsweisen beitragen könnten, immer noch ungenügend entwickelt. Dieser Beitrag zielt darauf ab, einen theoretischen Hintergrund für Strategien zum Umgang mit Gewalt bei Wahlen und zur Prävention zu entwickeln. Zu diesem Zweck kombinieren die Autorinnen Ergebnisse zweier Forschungsbereiche – der Demokratisierungsforschung und der Forschung zum Konfliktmanagement – und ziehen außerdem Erfahrungen aus der konfliktbeladenen südafrikanischen Provinz KwaZulu-Natal heran. Sie identifizieren fünf Strategien: Monitoring, Mediation, gesetzliche Maßnahmen, Sanktionierung und Selbsthilfepraktiken. Die Autorinnen diskutieren die Wirkungsweisen und Erfolgsaussichten, aber auch die Grenzen dieser Strategien und machen einige konkrete Vorschläge zur Erhöhung der Sicherheit bei Wahlen.

    The article describes the main results of the European Hot-Dry-Rock Project Soultz of the last 2 years. After a series of successful stimulation experiments and single-well hydraulic tests in the first deep well GPK1 (3590 m) in the previous project period the second deep well GPK2 (3876 m) was drilled during the winter 1994/95 in order to complete the doublet-system. Through the second well successfully penetrated the southern wing of the fracture system created in GPK1 the hydraulic connection was poor and a massive stimulation test had to be performed in GPK2 too. During this test a fracture system of about 1 km{sup 2} in size was stimulated in the depth range below 3200 m. This fracture system overlaps and penetrates the fracture system of borehole GPK1. (orig./AKF) [Deutsch] Der Artikel beschreibt die wesentlichen Ergebnisse des Hot-Dry-Rock Projekts Soultz der letzten beiden Jahre. Nach den erfolgreichen Einbohrloch-Tests in der Bohrung GPK1 in der vorangehenden Projektphase, bei denen ein ca. 1,5 km{sup 2} grosses kuenstliches Risssystem geschaffen wurde, aus dem infolge eines hydraulischen Anschlusses an grossraeumige permeable Stoerungszonen beachtliche Produktionsraten erzielt werden konnten, wurde im Winter 1994/95 die zweite Tiefbohrung GPK2 abgeteuft, um das Dublettensystem zu komplettieren. Trotz des erfolgreichen Abteufens der zweiten Bohrung in den Suedfluegel des bestehenden Risssystems, erwies sich der hydraulische Anschluss zunaechst als unzureichend, so dass ein massiver Stimulationstest in der neuen Bohrung angesetzt werden musste. Bei diesem Test wurden im Teufenbereich unterhalb 3200 m ein ca. 1 km{sup 2} grosses Risssystem erzeugt, das das Risssystem der Bohrung GPK1 ueberlappt und teilweise durchdringt. (orig./AKF)

  16. Was uns nicht umbringt, macht uns härter? Resilienzförderung bei armen Kindern aus Sicht des Capability-Ansatzes

    Directory of Open Access Journals (Sweden)

    Gutwald Rebecca

    2015-07-01

    Full Text Available Resilienz wird in der Psychologie und Sozialpädagogik häufig als positiv angesehen. In der Armutsbekämpfung ist diese Sichtweise durchaus nachvollziehbar, insbesondere in der Prävention von Kinderarmut: wenn Resilienz das ist, was ein Kind in die Lage versetzt, die Risiken und negativen Folgen von Armut besser zu bewältigen, scheint es sinnvoll, diese Fähigkeit bei Kindern zu fördern. Mein Beitrag befürwortet diesen Befund, plädiert aber dafür, dass die Resilienzdebatte der Untermauerung durch Argumente aus der praktischen Philosophie bedarf, da das, was häufig als Resilienz bezeichnet wird, nicht immer positiv zu bewerten ist. Ziel meines Beitrags ist es, den Resilienzdiskurs im Rahmen der Kinderarmutsbekämpfung in einer normativen Theorie zu verankern: im Capability Ansatz von Amartya Sen. Resilienz wird damit, so meine These, zu einem fundamental normativen Begriff. Mein Beitrag gliedert sich in drei Teile: Zuerst wird auf die Grundideen des CA und die Stellung von Kindheit darin eingegangen. Im zweiten Teil wird der Resilienzbegriff im Kontext von Kinderarmutsprävention charakterisiert. Der dritte Teil widmet sich den Verbindungslinien zwischen der Resilienzdiskussion und dem CA. Leitgedanke ist dabei, dass der CA die menschliche Handlungsfähigkeit als normativ grundlegend auszeichnet. Auf dieser Basis lässt sich überzeugend beurteilen, warum Armut bei Kindern höchst problematisch ist und welches Ziel in der Resilienzförderung verfolgt werden soll. Wie ich argumentieren werde, ist die Bereitstellung von capabilities auch die gerechtigkeitstheoretische Basis von Resilienzförderung in der Praxis. Der Beitrag schließt mit Impulsen, welche, so meine Hoffnung, für eine weitere Diskussion der Normativität von Resilienz dienlich sein können.

    Flash pyrolysis is a medium-temperature process (around 475 C) in which biomass is heated up rapidly in the absence of oxygen. The pyrolysis products are cooled down rapidly, condensing into a reddish-brown liquid with around half the calorific value of a conventional heating oil. In contrast to conventional charcoal production, flash pyrolysis is a modern process whose process parameters enure high liquid yields. Modern fluidized-bed reactors for flash pyrolysis of biomass tend to have high heating rates and short times of residue. In the `Hamburg process`, fluidized-bed reactors are used successfully for pyrolysis of plastics. A flash pyrolysis plant for biomass treatment was constructed in cooperation with Hamburg University with funds provided by the `Bundesstiftung Umwelt`. This contribution describes the first series of experiments, mass balances and oil analyses using beech wood as material to be pyrolyzed. (orig./SR) [Deutsch] Flash-Pyrolyse ist ein Mitteltemperatur-Prozess (ca. 475 C), in dem Biomasse unter Sauerstoffausschluss sehr schnell erhitzt wird. Die entstehenden Pyrolyseprodukte werden schnell abgekuehlt und kondensieren zu einer roetlich-braunen Fluessigkeit, die etwa die Haelfte des Heizwertes eines konventionellen Heizoeles besitzt. Flash-Pyrolyse ist, im Gegensatz zur konventionellen Holzverkohlung, ein modernes Verfahren, dessen spezielle Verfahrensparameter hohe Fluessigausbeuten ermoeglichen. Hohe Aufheizraten, verbunden mit kurzen Verweilzeiten, werden mit stationaeren Wirbelbettreaktoren erzielt die gegenwaertig vorwiegend fuer die Flash-Pyrolyse von Biomasse eingesetzt werden. Im `Hamburger Verfahren` haben sich Wirbelbettreaktoren im Bereich der Kunststoffpyrolyse bewaehrt. Daher wurde in Zusammenarbeit mit der Universitaet Hamburg und finanzieller Foerderung der Bundesstiftung Umwelt eine Flash-Pyrolyseanlage fuer Biomasse gebaut: In dieser Arbeit werden erste Versuchsreihen, Massenbilanzen und Oelanalysen aus der Pyrolyse von

Foi possível encontrar uma marca específica para a ausência de sementes, utilizando o iniciador UBC 443, que poderá futuramente ser utilizado para o desenvolvimento de marcadores SCAR, possibilitando a criação de um teste de identificação rápida e precoce de apirenia em videira. A análise fAFLP proporcionou a visualização de um dendrograma com grupos específicos de cultivares com sementes, sem sementes e porta enxertos.Seedless has been an important characteristic of table grapes required by consumers. The objective was to identify molecular markers associated to seedless, by RAPD and fAFLP techniques with young leaves samples of 19 cultivars. Thirty primers were used for RAPD analysis, producing a total of 337 polymorphic bands. It was also to find a specific mark for seedless, using UBC 443 primer. This mark would be transformed in a scar marker, making possible the early identification of seedless grape possible. The fAFLP analysis provided a visualization of a dendrogram with specific groups, separated in three different cultivars: with seeds, without seeds and the rootstocks.

    Full Text Available Iron(II, cobalt(II, nickel (II, copper (II, zinc(II and cadmium(II complexes of the type ML2Cl2, where M is a metal and L is the Schiff base N-(2-thienylmethylenemethanamine (TNAM formed by the condensation of 2-thiophenecarboxaldehyde and methylamine, were prepared and characterized by elemental analysis as well as magnetic and spectroscopic measurements. The elemental analyses suggest the stoichiometry to be 1:2 (metal:ligand. Magnetic susceptibility data coupled with electronic, ESR and Mössbauer spectra suggest a distorted octahedral structure for the Fe(II, Co(II and Ni(II complexes, a square-planar geometry for the Cu(II compound and a tetrahedral geometry for the Zn(II and Cd(II complexes. The infrared and NMR spectra of the complexes agree with co-ordination to the central metal atom through nitrogen and sulphur atoms. Conductance measurements suggest the non-electrolytic nature of the complexes, except for the Cu(II, Zn(II and Cd(II complexes, which are 1:2 electrolytes. The Schiff base and its metal chelates were screened for their biological activity against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa and the metal chelates were found to possess better antibacterial activity than that of the uncomplexed Schiff base.

    In an attempt to restore the competitive power of hazardous-waste incineration within the present legal framework, plant operators have in some cases lowered disposal prices below the break-even point; in this respect there is no further room for improvement. One approach towards a new marketable solution could be to use rotary kilns not only for disposal but also as production plants. This could be achieved by means of input control and loading materials. If, for example, the slag remaining after combustion could be made to meet building material specifications, thus providing a marketable product, then rotary kilns would be able to serve as production plants for a secondary raw material. If it should prove possible in the course of manufacturing campaigns to develop slags from hazardous-waste incineration plants to a marketable product, then operators will thus have complied to the demand of the Law on Recycling and Waste Management for waste avoidance and that of the Emission Control Law for residue recycling. Targeted use of suitable loading materials for quality improvement could enable operators of hazardous-waste incineration plants to secure a new strategic position on the market as building material manufacturers and utilise existing plant capacities. [Deutsch] Um die Sonderabfallverbrennung im Rahmen der rechtlichen Vorgaben wieder konkurrenzfaehig zu machen, haben die Anlagenbetreiber die Entsorgungspreise teilweise unter die Grenze der Kostendeckung zurueckgenommen; hier besteht kein Spielraum mehr. Ein neuer, marktgerechter Ansatz koennte sich dann ergeben, wenn die Drehrohroefen statt als Beseitigungsaggregate durch Inputsteuerung und Zuschlaege eventuell auch als Produktionsanlagen einzusetzen waeren. Wenn z.B. die Schlacke, als Rueckstand aus der Verbrennung, als ein im Baustoffmarkt absetzbares Produkt nach Qualitaetskriterien gezielt hergestellt wuerde, koennte der Drehrohrofen als Produktionsanlage fuer einen Sekundaerrohstoff betrieben werden

    An operational contrail detection algorithm is applied to day and night overpasses of the Advanced Very High Resolution Radiometer (AVHRR). From the classification results the daytime and nighttime coverage by linear shaped contrails over Western Europa is derived. The annual daytime average for the analyzed region of 0.75% shows a strong annual cycle with 1.0% coverage during winter and 0.4% during summer. The day/night ratio reaches the factor 3. Using the radiance contrasts in the 11 {mu}m channel for contrail and adjacent pixels an average visible optical depth for the observed contrails of 0.1 is derived. This leads to an annual mean top of atmosphere radiative forcing by contrails over Central Europe in the range of 0.03 W/m{sup 2} to 0.08 W/m{sup 2}, which is about one magnitude smaller than prior studies suggest. The highest annual mean contrail forcing exceeds 0.12 W/m{sup 2} over Northeastern France, Belgium, Great Britain and Hungary. (orig.) [German] Ein operationelles Kondensstreifen-Erkennungsverfahren wird auf Tag- und Nacht-Ueberfluege des Advanced Very High Resolution Radiometer (AVHRR) angewandt. Aus den Klassifizierungsergebnissen wird die mittaegliche und naechtliche Bedeckung durch linienhafte Kondensstreifen ueber Westeuropa abgeleitet. Das Jahresmittel der Bedeckung am Tag betraegt 0,75% und zeigt einen ausgepraegten Jahresgang mit 1% im Winter und 0,4% im Sommer, sowie einen starken Tag/Nacht-Unterschied mit einer Amplitude von 3. Mit Hilfe von Strahldichtekontrasten im 11 {mu}m Kanal zwischen Kondensstreifen und benachbarten Pixeln wird fuer die erkannten Kondensstreifen eine durchschnittliche optische Dicke im sichtbaren Spektralbereich von 0,1 abgeschaetzt. Daraus ergibt sich am Oberrand der Atmosphaere ein mittlerer auf Kondensstreifen zurueckzufuehrender Strahlungsantrieb zwischen 0,03 W/m{sup 2} und 0,08 W/m{sup 2}, was eine Groessenordnung unter den Ergebnissen bisheriger Studien liegt.

    Nanostructured thin films of crystalline TiO{sub 2} for applications in photovoltaics were studied. The fabrication of the thin films is based on a hybrid approach. The anorganic metal oxide prepared via a sol-gel synthesis is structurated by the template properties of the applied organic block-copolymer. Via the film epitaxy by means of centrifugal coating first hybrid films (polymer-nanocomposite films) were fabricated, which were changed by calcination into crystalline TiO{sub 2} films with taylored morphology. The successful development of novel preparation approaches to the adaption to consisting conditions in the application field of photovoltaics contains a route to the fine-tuning of the morphology as well as the fabrication of hierarchical morphologies in different configurations. The structural study of the single nanostructurated TiO{sub 2} films up to the functional multilayer arrangement as photovoltaic demonstration cell was performed with conventionally imaging methods, as for instance scanning force microscopy and electron microscopy as well as the special small-angle X-ray scattering method under rigid incident angle (GISAXS). [German] Es wurden nanostrukturierte duenne Filme aus kristallinem TiO{sub 2} fuer Anwendungen in der Photovoltaik untersucht. Die Herstellung der duennen Filme basiert auf einem Hybridansatz. Das ueber eine Sol-Gel-Synthese bereitgestellte anorganische Metalloxid wird durch die Template-Eigenschaften des eingesetzten organischen Block-Copolymers strukturiert. Ueber die Filmaufbringung mittels Schleuderbeschichtung wurden zunaechst Hybridfilme (Polymer-Nanokompositfilme) hergestellt, die durch Kalzinierung in kristalline TiO{sub 2}-Filme mit massgeschneiderter Morphologie umgewandelt werden. Die erfolgreiche Entwicklung von neuartigen Praeparationsansaetzen zur Adaption an bestehende Gegebenheiten im Anwendungsgebiet der Photovoltaik beinhaltet eine Route zur Feineinstellung der Morphologie sowie die Herstellung von

    Hydraulic in-situ remediation technologies have recently become more and more important for removing underground contamination especially in urban districts. To enhance the traditional pump-and-treat, substances such as surfactants can be used which not only dissolve but also mobilize the contaminants. For this method to be cost effective, an optimized waste water treatment is essential. On the one hand the contaminants are to be removed from the extracted ground water and on the other hand the surfactants are to be recycled for re-use in the remediation procedure. So far adsorption of contaminants on activated carbon has been applied to reach this goals. In the frame of this diploma thesis however, more efficient and more economical alternatives to the adsorption method were to be investigated. For this, three different separating techniques to treat water-surfactant-contaminant mixtures containing polycyclic aromatic hydrocarbons (PAH) as model substances were examined: a membrane technique by using an entrainer on the permeate side, the so called pertraction, the solvent extraction with petroleum ether as a solvent and the adsorption with other adsorbents. (orig.) [German] Hydraulische in-situ Sanierungsverfahren erfahren derzeit im Rahmen der Altlastenbearbeitung eine zunehmende Bedeutung zur Beseitigung von Untergrundkontaminationen, vor allem in innerstaedtischen Bereichen. Um die traditionelle 'pump and treat'-Methode zu optimieren, koennen Hilfsstoffe wie Loesungsvermittler, z.B. Tenside, eingesetzt werden, die eine sowohl solubilisierende als auch mobilisierende Wirkung auf die Schadstoffe haben. Um dieses Verfahren kosteneffektiv zu gestalten, ist eine optimierte Abwasseraufbereitung gefordert. Dabei sind zum einen die Schadstoffe aus dem extrahierten Grundwasser abzutrennen und zum anderen die Tenside fuer das Verfahren zurueckzugewinnen. Zum bisher dafuer angewandten Adsorptionsverfahren unter Einsatz von Aktivkohle sollten im Rahmen dieser

    A probable evolutionary sequence of H II regions based on six distinct types of observed objects is suggested. Two examples which may deviate from this idealized sequence, are discussed. Even though a size-mean density relation of H II regions can be used as a rough indication of whether a nebula is very young or evolved, it is argued that such a relation is not likely to be useful for the quantitative assignment of ages to H II regions. Evolved H II regions appear to fit into one of four structural types: rings, core-halos, smooth structures, and irregular or filamentary structures. Examples of each type are given with their derived physical parameters. The energy balance in these nebulae is considered. The mass of ionized gas in evolved H II regions is in general too large to trace the nebula back to single compact H II regions. Finally, the morphological type of the Galaxy is considered from its H II region content. 2 tables, 2 figs., 29 refs

    1980-01-01

    The upgrade of Sandia National Laboratories particle beam fusion accelerator, PBFA I, to PBFA II presents several interesting and challenging pulsed power design problems. PBFA II requires increasing the PBFA I output parameters from 2 MV, 30 TW, 1 MJ to 4 MV, 100 TW, 3.5 MJ with the constraint of using much of the same PBFA I hardware. The increased PBFA II output will be obtained by doubling the number of modules (from 36 to 72), increasing the primary energy storage (from 4 MJ to 15 MJ), lowering the pulse forming line (PFL) output impedance, and adding a voltage doubling network

    2017-01-01

    Set to begin data taking at the end of 2018, the Belle II experiment is the next-generation B-factory experiment hosted at KEK in Tsukuba, Japan. The experiment represents the cumulative effort from the collaboration of experimental and detector physics, computing, and software development. Taking everything learned from the previous Belle experiment, which ran from 1998 to 2010, Belle II aims to probe deeper than ever before into the field of heavy quark physics. By achieving an integrated luminosity of 50 ab−1 and accumulating 50 times more data than the previous experiment across its lifetime, along with a rewritten analysis framework, the Belle II experiment will push the high precision frontier of high energy physics. This paper will give an overview of the key components and development activities that make the Belle II experiment possible.

    OptiComp is currently completing a 32-bit, fully programmable digital optical computer (DOC II) that is designed to operate in a UNIX environment running RISC microcode. OptiComp's DOC II architecture is focused toward parallel microcode implementation where data is input in a dual rail format. By exploiting the physical principals inherent to optics (speed and low power consumption), an architectural balance of optical interconnects and software code efficiency can be achieved including high fan-in and fan-out. OptiComp's DOC II program is jointly sponsored by the Office of Naval Research (ONR), the Strategic Defense Initiative Office (SDIO), NASA space station group and Rome Laboratory (USAF). This paper not only describes the motivational basis behind DOC II but also provides an optical overview and architectural summary of the device that allows the emulation of any digital instruction set.

    The content of molecular nitrogen in the natural gas deposits of the Northwest-German basin can show values of up to 100 volume percent (nitrogen province) and therefore carry a high exploration risk. Analysis of the generation of the gas from carboniferous clay stone by means of open pyrolysis shows that the nitrogen generation potential is relatively high when compared to coal (according to TOC standards). This analysis enabled the determination of generation graphs for nitrogen, partly also for methane, from Namur clay stones of a maturity between 2.81 and 3.86 volume percent. (orig.).

    Valves made of silicon nitrice ceramics have advantages over metal valves owing to their low density, high wear resistance, low thermal conductivity and high termperature resistance. Reciprocating piston engines with ceramic valves have a lower fuel consumption, lower noise, and lower exhaust emissions. On the other hand, ceramic materials have the disadvantage of being brittele, i.e. mechanical stress concentrations at crack tips cannot be removed by plastic deformation. In order to ensure safe application in piston engines, all ceramic valves must therefore be tested by nondestructive methods in order to detect and replace defective valves. [German] Ventile aus Siliciumnitrid-Keramik haben infolge ihrer geringen Dichte, hohen Verschleissfestigkeit, niedrigen Waermeleitfaehigkeit und hohen Temperaturfestigkeit gegenueber Ventilen aus metallischen Werkstoffen ganz entscheidende Vorteile. So haben Hubkolbenmotoren mit Keramikventilen einen deutlich geringeren Treibstoffbedarf und zeigen bei einem erheblich reduzierten Geraeuschpegel eine schadstoffaermere Abgasentwicklung. Diesen Vorteilen steht die allen keramischen Werkstoffen gemeinsame Eigenschaft der Sproedigkeit gegenueber. So koennen mechanische Spannungskonzentrationen an Rissspitzen nicht durch plastische Verformung abgebaut werden. Fuer den sicheren Einsatz im Hubkolbenmotor muessen daher die Keramikventile einer zerstoerungsfreien Bewertung unterzogen werden, um fehlerhafte Ventile zu erkennen und auszuscheiden. (orig.)

    This report (`Organic Trace Compounds as Emissions of Incineration Plants and their Toxicological and Ecotoxicological Classification - Part 1: Organic Emissions`) describes the reaction pathways in the flame chemistry of organic materials. Possible organic products of incomplete combustion formed at the trace level in various processes are summarized. The emissions of organic compounds from municipal waste incineration plants are named in detail and compared to those of other combustion processes, like e.g. the combustion of coal, sewage sludge or fuels. Quantitative figures are given if available. (orig.) [Deutsch] Im vorliegenden Arbeitsbericht (`Organische Spurenstoffe als Emissionen aus Verbrennungsanlagen und deren humantoxikologische und oekotoxikologische Einordnung - Teil 1: Organische Emissionen`) werden die grundlegenden chemischen Prozesse bei der unvollstaendigen Verbrennung von organischem Material beschrieben und die dabei als Spurenstoffe entstehenden Substanzklassen benannt. Im Tabellenteil werden die Emissionen von organischen Verbindungen aus Abfallverbrennungsanlagen qualitativ und quantitativ mit den Emissionen bei anderen thermischen Prozessen - z.B. Verbrennung von Kohle, Klaerschlamm oder Treibstoffen - verglichen. Dabei wurde auf groesstmoegliche stoffliche Differenzierung und vollstaendige Erfassung der Emissionen geachtet. (orig.)

    High alloyed superaustenitic steels and NiCrMo alloys are recommended in consequence of the results of extensive laboratory corrosion experiments under the strong corrosive conditions with up to 360 g chloride content at temperatures up to 85 C. Because results of laboratory corrosion tests are only of limited relevance to the behaviour in practice, field tests were carried out with immersion of welded materials and of heat exchanger tubes under operating conditions of an evaporation plant for waste water from flue gas desulphurization of a coal-fired power plant. Different kinds of high alloy superaustenitic steels and NiCrMo alloys were studied as TIG-welded specimens in immersion tests. (orig.) [German] Hochlegierte Sonderedelstaehle und NiCrMo-Legierungen empfehlen sich aufgrund der Ergebnisse umfassender Laboruntersuchungen unter den stark korrosiven Bedingungen fuer Eindampfanlagen fuer Abwasser aus der Nassreinigung von Rauchgasen von Grossfeuerungsanlagen mit bis zu 360 g/l Chloridgehalt und Temperaturen bis zu 85 C. Weil aber Ergebnisse von Laborpruefungen nur begrenzte Aussagefaehigkeit fuer das Verhalten unter Praxisbedingungen haben, wurden Feldversuche mit der Auslagerung geschweisster Werkstoffe und von Waermetauscherrohren unter Betriebsbedingungen einer Eindampfanlage fuer Abwasser aus der Rauchgasentschwefelung eines kohlebefeuerten Kraftwerks durchgefuehrt.

    For collecting biomass waste, about 65,000 households in the Bad Duerkheim district were given ten bags each of the compostable BASF plastic material Ecovio {sup registered} FS. The biomass waste collected in the Ecovio {sup registered} bags were composted in a composting plant. After the compost process, no residues of the Ecovio {sup registered} bags were found in the rotting, i.e. they are completely degradable. Neither the compost quality nor the working processes in the composting plant were affected, and there was no bigger volume of sorting residues. 90% of the users stated that they were satisfied with the new biomass waste bags. (orig.) [German] Fuer die Entsorgung des Bioabfalls erhielten rund 65.000 Haushalte aus dem Landkreis Bad Duerkheim je zehn Biomuelltuten aus dem kompostierbaren BASF-Kunststoff Ecovio {sup registered} FS. Die in diesen Ecovio {sup registered} -Tueten gesammelten Bioabfaelle wurden im Biokompostwerk zu Kompost verarbeitet. Nach dem Kompostierungsprozess konnten keine Reste der Ecovio {sup registered} -Folien mehr in der Rotte gefunden werden, und sie wurden vollstaendig biologisch abgebaut. Durch den Einsatz dieser Tueten wurden weder die Kompostqualitaet noch die Arbeitsablaeufe im Biokompostwerk beeintraechtigt. Eine Erhoehung der Sortierreste war nicht festzustellen. Im Rahmen einer Kundenbefragung aeusserten sich rund 90% zufrieden mit dem Einsatz dieser Biomuelltueten. (orig.)

    The photophysical and photochemical properties of photocatalysts capable of working under solar-light-irradiation are of great interest. An especially promising application is the development of low-cost `Advanced Oxidation Procedures` (AOP). The aim of this endeavor is the detoxification of hazardous chemicals in wastewaters, which cannot be treated by conventional techniques. The mineralization of the most (highly) toxic chemicals to CO{sub 2}, H{sub 2}O and simple inorganic compounds is favored by thermodynamics, however various difficulties such as kinetic barriers and hindered diffusion exist in systems for heterogeneous photocatalysis. In that respect, Ruthenium(II)-tris-bipyridine ([Ru(bpy){sub 3}]{sup 2+}) and TiO{sub 2} - codoped photocatalysts offer several advantages. The photoreactive centers consist of supramolecular units of [Ru(bpy){sub 3}]{sup 2+} and TiO{sub 2} - nanocrystals. Pollutants, such as our model compound 2,4-Dimethylaniline, diffuse through the framework of zeolite Y and undergo oxidative degradation at the reactive centers of the photocatalysts in the presence of H{sub 2}O{sub 2}. Under the aspect of application, the size of the zeolite Y-particles (diameter: 1x10{sup -6} m in average) permits their easy handling in filtration and recyling operations. (orig.) [Deutsch] Die photophysikalischen und -chemischen Eigenschaften von Katalysatoren, die das Licht der Sonne als kostenguenstige Energiequelle ausnutzen, treten immer staerker in den Vordergrund des Interesses.

Die Mineralisation der meisten (hoch)giftigen Chemikalien zu CO{sub 2}, H{sub 2}O und einfachen anorganischen Verbindungen ist zwar thermodynamisch beguenstigt, es treten jedoch sowohl kinetische Hemmschwellen als auch Diffusionshindernisse in der heterogenen Photokatalyse auf.

    Self-assembled monolayers (SAMs) of butanethiolate (C4) on single crystalline Au(111) surfaces were prepared by adsorption from solution. The thermally activated desorption behaviour of the C4 molecules from the gold substrate was examined by qualitative thermal desorption measurements (TDM), through this a desorption temperature T{sub Des}=473 K could be determined. With this knowledge, it was possible to produce samples of very good surface quality, by thermal treatment T{sub Sample}Au-S bond of the thiolate. The energy of the other resonance state agreed well with an interface state reported before for SAMs of an other alkanethiol on Au(111) in a densely packed phase. Furthermore the 2PPE data indicated that the high quality of the ex situ prepared SAMs supported the formation of image potential states. The reversible photo- and thermally activated isomerization of the molecular switch 3-(4-(4-Hexyl-phenylazo)-phenoxy)-propane-1-thiol (ABT), deposited by self-assembly from solution on Au(111), was examined using laser-based photoelectron spectroscopy. Differences in the molecular dipole moment characteristic for the trans and the cis isomer of ABT were observed via changes in the sample work function, accessible by detection of the threshold energy for photoemission.

    Main topic of the project was the manufacturing of highly efficient GaAs-solar cells and the fabrication of concentrator cells. During this process significant progress was made with the material preparation, the solar cell technology and the material and process characterisation. This succeeded in the following efficiencies: - GaAs solar cell made by MOVPE technology: 22.9% on 4 cm{sup 2} (AM1.5g) - GaAs solar cell made by LPE-ER process: 22.8% on 4 cm{sup 2} (AM1.5g) - GaAs concentrator solar cell made by LPE-ER process: 24.9% at C=100xAM1.5d - GaAs concentrator module with fresnel lenses: Module efficiency 20.1% (under irradiation of 793 W/m{sup 2}). Another main focus was the epitaxy of GaAs on Si substrate. Two different approaches were investigated. Together with the cooperation partner ASE, Heilbronn a selective growth technology was developed that led to a decreased crack formation. By a simultanous optimization of the other epitaxy and process parameters, the efficiency was increased up to 16.6% AM0 on 1 cm{sup 2} solar cells. Furthermore a hybrid epitaxy was investigated. A GaAs layer was deposited onto a Si substrate using MOVPE. The solar cell structure was grown with a low temperature LPE. Unexpected difficulties appeared with this process, so that fundamental experiments needed to be done with the LPE technology. So far, no solar cells could be manufactured with this method. In addition, work was performed on GaInP solar cells on GaAs substrate. An efficiency of 15.7% (AM0) was acchieved. (orig.) [Deutsch] Gegenstand des Projekts war die Herstellung hocheffizienter GaAs-Solarzellen und die Fertigung von Konzentratorsolarzellen.

    The operation of an APPLE II based undulator beamline with all its polarization states (linear horizontal and vertical, circular and elliptical, and continous variation of the linear vector) requires an effective description allowing an automated calculation of gap and shift parameter as function of energy and operation mode. The extension of the linear polarization range from 0 to 180 deg. requires 4 shiftable magnet arrrays, permitting use of the APU (adjustable phase undulator) concept. Studies for a pure fixed gap APPLE II for the SLS revealed surprising symmetries between circular and linear polarization modes allowing for simplified operation. A semi-analytical model covering all types of APPLE II and its implementation will be presented

    Full Text Available It is a century since the army of Victor Manuel invaded Rome and put an end to Vatican I. In this article we try to understand Vatican II linking it to the previous circumtances and binding it to its doctrinal and pastoral character. Vatican II omitted many subjects that seemed important, e. g. not giving any dogmatic definitions. Contrasting with the Tridentine and Vatican I, that were mostly doctrinal, Vatican II was pastoral. But it was also doctrinal as were the two previous also pastoral. The Constitution "Dei Verbum" brings forth the intentions that led John XXIII to summon the Council in 5-8-1962. The world looked confused and agitated. What could the Church do?

    The Russian-American Gallium solar neutrino Experiment (SAGE) began the second phase of operation (SAGE II) in September of 1992. Monthly measurements of the integral flux of solar neutrinos have been made with 55 tonnes of gallium. The K-peak results of the first nine runs of SAGE II give a capture rate of 66 -13 +18 (stat) -7 +5 (sys) SNU. Combined with the SAGE I result of 73 -16 +18 (stat) -7 5 (sys) SNU, the capture rate is 69 -11 +11 (stat) -7 +5 (sys) SNU. This represents only 52%--56% of the capture rate predicted by different Standard Solar Models

O Vaticano II implica uma transição de uma Igreja clerical a uma Igreja Povo de Deus, povo de batizados. A passagem de uma Igreja juridicista e legalista a uma Igreja Mistério de comunhão em Cristo. Mudar de uma Igreja triunfalista e ligada ao poder mundano a uma Igreja vivificada pela força renovadora do Espírito. A Igreja está a caminho rumo ao Reino de Deus juntamente com todos os cristãos e com toda a humanidade. A recepção do Vaticano II supõe uma conversão pastoral: voltar ao Evangelho e abrir-se aos novos sinais dos tempos seguindo o Espírito que inspirou João XXIII. ABSTRACT: You cannot understand the Ecclesiology of Vatican II without knowing the life, the pastoral style and the charisma of John XXIII, who convened the Council and opened the way toward a new ecclesial setting that ended centuries of a church of Christendom. The Vatican II involves a transition from a clerical Church to a “People (baptized people of God” Church. The Vatican II implies the passage from a juridical and legalistic Church to a Church as the Mystery of the communion in Christ. The Vatican II implies the change from a triumphalistic Church and connected to worldly power to a Church vivified by the renewing force of the Spirit. The Church is on its way toward the Kingdom of God together with all Christians and all mankind. The reception of the Vatican II supposes a pastoral conversion: a return to the Gospel and openness to new signs of the times following the Spirit that inspired John XXIII.

    Full Text Available O preparo do solo, o qual influencia o manejo dos resíduos culturais e a rugosidade superficial, associado ao tipo de cultura utilizada, é um dos fatores que afetam a suscetibilidade do solo à erosão hídrica. Utilizando chuvas simuladas na intensidade constante de 64 mm h-1, com durações suficientes para que o escoamento superficial atingisse taxa constante de descarga, foram avaliados, em Eldorado do Sul (RS, de 1992 a 1994, em condições de campo, os seguintes tratamentos de preparo do solo: semeadura direta, na presença e na ausência dos resíduos recém-colhidos de milho e trigo; escarificação, na presença e na ausência dos resíduos recém-colhidos de milho e trigo + milho logo após a colheita do trigo; e aração + gradagem, na presença e ausência dos resíduos recém-colhidos de milho e trigo + milho logo após a colheita do trigo. Utilizou-se um solo podzólico vermelho-amarelo franco-arenoso e declividade média de 0,066 m m-1. As perdas de solo e água foram fortemente influenciadas pela rugosidade e cobertura superficiais. Na semeadura direta e aração + gradagem, a manutenção dos resíduos culturais na superfície reduziu as perdas de solo em relação à sua remoção manual quase completa. A semeadura direta com os resíduos culturais foi o tratamento mais eficaz na redução da erosão e a aração + gradagem, sem os resíduos, o menos eficaz. A escarificação com os resíduos culturais na superfície apresentou maior perda de solo do que a semeadura direta e aração + gradagem também com os resíduos na superfície. Em geral, as perdas de água por escoamento superficial seguiram o mesmo comportamento das perdas de solo.

    If we apply the multistep method of W. Gear for the integration of a system of ordinary differential equations to the nonlinear heat conduction equation in the implementation EPISODE, this results in memory problems due to the band structure of the Jacobian, because EPISODE uses a LU-decomposition with pivoting. The report describes measures which suit this method to the actual conditions. If we use the storage scheme for sparse matrices from Liebau, Rudolphi, only the nonzero elements of the Jacobian are stored. In case of a linear problem, this matrix only has to be computed once. The BI-CGSTAB-method, an iterative method, replaces the LU-decomposition resp. the solution of the linear (and possibly non-symmetric) system of equations resulting from the corrector step. If {tau} is the time step length and h the space step length, this BICG-variant has good convergence properties for a moderate ratio of {tau}/h{sup 2}. The report also includes a short description of the program INSTATCP developed in Borland Delphi 4/Object Pascal. Two applications from the field of fire protection and thermal insulation in buildings (fire insulated steel column and vertically perforated brick) show that the modifications of the Gear method work effectively. (orig.) [German] Wird das Mehrschnittverfahren von W.

Durch die Verwendung des Speicherschemas fuer Sparse-Matrizen aus Liebau, Rudolphi werden nur die Nichtnullelemente der Jacobi-Matrix gespeichert. Liegt insbesondere ein lineares Problem vor, so braucht diese Matrix nur einmal berechnet zu werden. Das BI-CGSTAB-Verfahren, also

  15. BeII** revisited

    International Nuclear Information System (INIS)

    Fischer, C.F.

    1982-01-01

    Doubly excited 1s2snl and 1s2pnl quartet states of BeII** are readily populated in beam-foil experiments and line-rich spectra have been obtained covering 600 to 5500 A wavelength range. In spite of several theoretical calculations a substantial number of observed lines have not been identified. The quartet system in BeII is an intersting one from a theoretical point of view. Three electron systems are simple enough that a fairly high level of accuracy is attainable without the calculations becoming horrendous. The important correlation effects are between the outer two electrons and, to a good approximation, the three-electrons system may be treated as a two-electron system outside a 1s-core. The multi-configuration Hartree-Fock (MCHF) method has been used successfully in a number of studies. Programs are under development that take into account the non-orthogonality of orbitals in the initial and final state, and allow for some non-orthogonal orbitals in a wavefunction expansion. LS dependent relativistic effects are also included. A study of BeII** was undertaken to evaluate the MCHF techniques being developed and to assit in the identification of observed lines. Most of the earlier calculations concentrated on the lower-lying levels. In this work particular attention was given to the more highly-excited states, though calculations for lower-lying states had to be repeated in order to predict life-times

  16. What is LAMPF II

    International Nuclear Information System (INIS)

    1982-08-01

    The present conception of LAMPF II is a high-intensity 16-GeV synchrotron injected by the LAMPF 800-MeV H - beam. The proton beam will be used to make secondary beams of neutrinos, muons, pions, kaons, antiprotons, and hyperons more intense than those of any existing or proposed accelerator. For example, by taking maximum advantage of a thick target, modern beam optics, and the LAMPF II proton beam, it will be possible to make a negative muon beam with nearly 100% duty factor and nearly 100 times the flux of the existing Stopped Muon Channel (SMC). Because the unique features of the proposed machine are most applicable to beams of the same momentum as LAMPF (that is, < 2 GeV/c), it may be possible to use most of the experimental areas and some of the auxiliary equipment, including spectrometers, with the new accelerator. The complete facility will provide improved technology for many areas of physics already available at LAMPF and will allow expansion of medium-energy physics to include kaons, antiprotons, and hyperons. When LAMPF II comes on line in 1990 LAMPF will have been operational for 18 years and a major upgrade such as this proposal will be reasonable and prudent

  18. Average [O II] nebular emission associated with Mg II absorbers: dependence on Fe II absorption

    Science.gov (United States)

    Joshi, Ravi; Srianand, Raghunathan; Petitjean, Patrick; Noterdaeme, Pasquier

    2018-05-01

    We investigate the effect of Fe II equivalent width (W2600) and fibre size on the average luminosity of [O II] λλ3727, 3729 nebular emission associated with Mg II absorbers (at 0.55 ≤ z ≤ 1.3) in the composite spectra of quasars obtained with 3 and 2 arcsec fibres in the Sloan Digital Sky Survey. We confirm the presence of strong correlations between [O II] luminosity (L_{[O II]}) and equivalent width (W2796) and redshift of Mg II absorbers. However, we show L_{[O II]} and average luminosity surface density suffer from fibre size effects. More importantly, for a given fibre size, the average L_{[O II]} strongly depends on the equivalent width of Fe II absorption lines and found to be higher for Mg II absorbers with R ≡W2600/W2796 ≥ 0.5. In fact, we show the observed strong correlations of L_{[O II]} with W2796 and z of Mg II absorbers are mainly driven by such systems. Direct [O II] detections also confirm the link between L_{[O II]} and R. Therefore, one has to pay attention to the fibre losses and dependence of redshift evolution of Mg II absorbers on W2600 before using them as a luminosity unbiased probe of global star formation rate density. We show that the [O II] nebular emission detected in the stacked spectrum is not dominated by few direct detections (i.e. detections ≥3σ significant level). On an average, the systems with R ≥ 0.5 and W2796 ≥ 2 Å are more reddened, showing colour excess E(B - V) ˜ 0.02, with respect to the systems with R < 0.5 and most likely trace the high H I column density systems.

    Full Text Available Complexes of Mn(II, Co(II, Ni(II, Pd(II and Pt(II were synthesized with the macrocyclic ligand, i.e., 2,3,9,10-tetraketo-1,4,8,11-tetraazacycoletradecane. The ligand was prepared by the [2 + 2] condensation of diethyloxalate and 1,3-diamino propane and characterized by elemental analysis, mass, IR and 1H NMR spectral studies. All the complexes were characterized by elemental analysis, molar conductance, magnetic susceptibility measurements, IR, electronic and electron paramagnetic resonance spectral studies. The molar conductance measurements of Mn(II, Co(II and Ni(II complexes in DMF correspond to non electrolyte nature, whereas Pd(II and Pt(II complexes are 1:2 electrolyte. On the basis of spectral studies an octahedral geometry has been assigned for Mn(II, Co(II and Ni(II complexes, whereas square planar geometry assigned for Pd(II and Pt(II. In vitro the ligand and its metal complexes were evaluated against plant pathogenic fungi (Fusarium odum, Aspergillus niger and Rhizoctonia bataticola and some compounds found to be more active as commercially available fungicide like Chlorothalonil.

    From the present report 'Untersuchungen zur Radionuklidfreisetzung und zum Korrosionsverhalten von bestrahltem Kernbrennstoff aus Forschungsreaktoren unter Endlagerbedingungen' with the code number FKZ 9108 carried out in the time periode 01.06.1998 till 30.11.2001 the following results can be withdrawn: U/Al-RR-fuel elements corroded slowly in granite water (Grimsel-West) at 90 C under anaerobic conditions. For a complete dissolution of the fuel element a time period of 10{sup 3} years is assumed according to present conservative results. In salt brines, especially in magnesium chloride rich brines the corrosion rate is high. Addition of GGG40 (basic material of the fuel element container with iron as main element) had an acceleration effect. A complete dissolution of the fuel is achieved within a couple of months. Under aerobic and under anaerobic conditions the bulk of released radionuclides were fixed by the corrosion products formed (secondary phases). The actinides were mobilised by variation of the ionic strength of the leaching solution. This process can be explained by phase conversion reactions within the secondary phases. Secondary phases formed by corrosion of a non-irradiated U/Al-RR-fuel element, were analysed and hydrotalcites were identified as phase components. This result justifies the assumption, that hydrotalcites are components of the corrosion products from irradiated fuels. To clarify the questions which bindings exist between radionuclides and secondary phases, sorption experiments were performed. The sorption experiments were performed in salt brines and in granite water using repository relevant radionuclides and minerals which are considered to represent thermodynamic final components of the secondary phases. Pu sorbed as cationic species quantitatively and the binding is covalent. In granite water the same behaviour was found for Am. (orig.)

    Full Text Available A persistência da veia cava superior esquerda com ausência da veia cava superior direita é uma anomalia rara, com menos de 150 casos descritos na literatura. A não-obliteração e regressão da veia cardinal anterior esquerda durante o desenvolvimento embriológico promove uma variação sistêmica de retorno venoso ao coração, com persistência da veia cava superior esquerda. Sua incidência varia de 0,3% em pacientes sem alterações cardíacas congênitas concomitantes a 4,3% naqueles com cardiopatias. Na maioria das vezes coexiste a veia cava superior direita, porém se houver regressão e degeneração da veia cardinal anterior direita, implicará a sua ausência e a drenagem venosa para o coração será feita pela veia cava superior esquerda ao átrio direito, através do seio coronariano. Mostramos um caso de um paciente submetido a radiografia de tórax e tomografia computadorizada para avaliação de doença pulmonar obstrutiva crônica, tendo como achado a persistência da veia cava superior esquerda com ausência da direita, sem qualquer cardiopatia associada e com a drenagem cardíaca sendo feita, através do seio coronariano, para o átrio direito.Persistent left superior vena cava with absent right superior vena cava is a rare anomaly, with less than 150 cases reported in the literature. Congenitally persistent left superior vena cava is the most common variant of systemic venous return to the heart, resulting embryologically from failure of the left anterior cardinal vein to become obliterated. Its incidence varies from 0.3% in patients with otherwise normal heart to 4.3% in patients with congenital heart disease. In the majority of the patients, a right superior vena cava is present as well, but rarely the right anterior cardinal vein degenerates resulting in the absence of the normal right superior vena cava. The blood from the right side is carried by the persistent left superior vena cava to the right atrium through the

    The purpose of this study was to evaluate the effects of a computerized procedure system, the Computerized Procedure Manual II (COPMA-II), on the performance and mental workload of licensed reactor operators. To evaluate COPMA-II, eight teams of two operators were trained to operate a scaled pressurized water reactor facility (SPWRF) with traditional paper procedures and with COPMA-II. Following training, each team operated the SPWRF under normal operating conditions with both paper procedures and COPMA-II. The teams then performed one of two accident scenarios with paper procedures, but performed the remaining accident scenario with COPMA-II. Performance measures and subjective estimates of mental workload were recorded for each performance trial. The most important finding of the study was that the operators committed only half as many errors during the accident scenarios with COPMA-II as they committed with paper procedures. However, time to initiate a procedure was fastest for paper procedures for accident scenario trials. For performance under normal operating conditions, there was no difference in time to initiate or to complete a procedure, or in the number of errors committed with paper procedures and with COPMA-II. There were no consistent differences in the mental workload ratings operators recorded for trials with paper procedures and COPMA-II

    In the field of turbo-compressors, the following problems must be solved in order to extend the range of operation: (a) Prevention of rotating stall at part load; (b) Extension of the permissible operating range at part load; (c) Extension of the operation range of radial and side channel compressors in higher vacuum below p{sub s}=50kPa. (c) can be achieved by changing the flow pattern in the rotor and in the region of interaction between the blade wheel and guide wheel of radial compressors or by actively influencing transient flow, e.g. by coupling radial compressor stages with a side channel compressor stage as final stage. The contribution goes into detail about the latter solution. [German] Fuer den Turboverdichterbau sind gegenwaertig folgende Probleme zur Erweiterung der Betriebsbereiche dringend zu loesen: (a) Vermeiden oder beseitigen von Rotating Stall im Teillastbereich,(b) Erweiterung des zulaessigen Arbeitsbereiches im Teillastgebiet, (c) Erschliessung des Arbeitsbereichs von Radial- und Seitenkanalverdichtern im hoeheren Vakuumbereich unterhalb von p{sub s}=50 kPa. Die Erweiterung des zulaessigen Arbeitsbereichs im Teillastgebiet kann durch Veraenderung der Stroemungsstruktur im Laufrad und im Interaktionsbereich zwischen Lauf- und Leitrad von Radialverdichtern oder durch die aktive Beeinflussung der instationaeren Stroemung z.B. durch Kopplung von Radialverdichterstufen mit einer Seitenkanalverdichterstufe als Endstufe erfolgen. Seitenkanalverdichter verfuegen ueber stabile Kennlinien im gesamten Betriebsbereich. Im Kombinationsbetrieb einer Radialverdichterstufe mit nach- oder vorgeschalteter Seitenkanalverdichterstufe praegte die Seitenkanalverdichterstufe dem Kombinationsverdichter ihr stabiles Kennlinienverhalten auf, so dass sich eine stabile Gesamtkennlinie ergibt. Eine Pumpgrenze tritt nicht mehr auf, so dass der Betrieb von Verdichterkombinationen aus Radial- und Seitenkanalstufe im gesamten Kennlinienbereich moeglich ist. Die

    The objective of the several RTNS-II irradation programs is to maximize information gained from the small test volume available in this unique irradiation facility for application in the fusion materials program. While this facility provides the highest 14 MeV neutron flux available, the flux is generally too low and the irradiation volume too small for testing of engineering materials. Emphasis, therefore, is on identifying damage mechanisms of high energy neutrons and correlating them quantitatively with effects produced by fission neutrons. The information gained will be used to evaluate and calibrate damage and correlation models under development. The scope of the program includes in-situ experiments, postirradiation experiments, irradiation temperatures ranging from 4 0 K to 1,000 0 K, and fluences ranging from 3 x 10 16 to about 3 x 10 19 n/cm 2

    Belle II is a next generation B factory experiment that will collect 50 times more data than its predecessor, Belle. The higher luminosity at the SuperKEKB accelerator leads to higher background levels and requires a major upgrade of the detector. As a consequence, the simulation, reconstruction, and analysis software must also be upgraded substantially. Most of the software has been redesigned from scratch, taking into account the experience from Belle and other experiments and utilizing new technologies. The large amount of experimental and simulated data requires a high level of reliability and reproducibility, even in parallel environments. Several technologies, tools, and organizational measures are employed to evaluate and monitor the performance of the software during development. (paper)

  20. Inside ISIS II

    1981-01-01

    ISIS stands for Identification of Secondaries by Ionization Sampling. It was a drift chamber with an active volume of about 40 m3 built by Oxford University as a particle identifier for the European Hybrid Spectrometer (EHS). The photo shows the electrostatic grading structure and the central anode-wire plane, with Roger Giles standing just under it (Annual Report 1981 p. 57, Fig. 4). ISIS-II differed from the prototype ISIS-I only in the depth of the track (4 m instead of 1 m) thus extending the momentum range for particle identification to 50 GeV/c. See Nucl. Instr. and Meth. 224 (1984) 396, and Nucl. Instr. and Meth. 258 (1987) 26.

    The PEP-II Asymmetric B-factory consists of two independent storage rings, one located atop the other in the 2200m-circumference PEP tunnel. The high-energy ring, which stores a 9-GeV electron beam, is an upgrade of the existing PEP collider. It re-utilizes all of the PEP magnets and incorporates a state-of-the-art copper vacuum chamber and a new RF system capable of supporting a one-amp stored beam. The low-energy ring, which stores 3.1-GeV positrons, is new construction. Injection is achieved by extracting electrons and positrons at collision energies from the SLC and transporting them each in a dedicated bypass line. The low-emittance SLC beams will be used for the injection process.

    Between 1966 and 1985, 32 patients with stage II (21 A,11 B) testicular seminoma were treated with postorchiectomy irradiation to the retroperitoneal and ipsilateral iliac nodes; 28 received elective mediastinal-supraclavicular irradiation. The median follow-up was 8 1/2 years; 29 patients were followed up for over 3 years and 24 for over 5 years. Twenty-eight patients remain alive and well and four have die, two of a second primary cancer. Two patients developed recurrent seminoma in the mediastinum; these patients showed a variant lymphangiographic pattern. Both remain well after further irradiation or irradiation plus chemotherapy. A third patient developed nonseminomatous ''recurrence'' in the radiation field and is well after chemotherapy

    The SkyTrough DSP will advance the state-of-the-art in parabolic troughs for utility applications, with a larger aperture, higher operating temperature, and lower cost. The goal of this project was to develop a parabolic trough collector that enables solar electricity generation in the 2020 marketplace for a 216MWe nameplate baseload power plant. This plant requires an LCOE of 9¢/kWhe, given a capacity factor of 75%, a fossil fuel limit of 15%, a fossil fuel cost of $6.75/MMBtu, $25.00/kWht thermal storage cost, and a domestic installation corresponding to Daggett, CA. The result of our optimization was a trough design of larger aperture and operating temperature than has been fielded in large, utility scale parabolic trough applications: 7.6m width x 150m SCA length (1,118m2 aperture), with four 90mm diameter × 4.7m receivers per mirror module and an operating temperature of 500°C. The results from physical modeling in the System Advisory Model indicate that, for a capacity factor of 75%: The LCOE will be 8.87¢/kWhe. SkyFuel examined the design of almost every parabolic trough component from a perspective of load and performance at aperture areas from 500 to 2,900m2. Aperture-dependent design was combined with fixed quotations for similar parts from the commercialized SkyTrough product, and established an installed cost of $130/m2 in 2020. This project was conducted in two phases. Phase I was a preliminary design, culminating in an optimum trough size and further improvement of an advanced polymeric reflective material. This phase was completed in October of 2011. Phase II has been the detailed engineering design and component testing, which culminated in the fabrication and testing of a single mirror module. Phase II is complete, and this document presents a summary of the comprehensive work.

    Full Text Available Article in German, Abstracts in English and German.When Humboldt in 1853 reread his 1804 notebook of his travel from Mexico City to Veracruz, he criticized his “old Neptunistic follies” in a marginal note. Scholars have doubted that he was still a Neptunist in 1804, but this text and Humboldt’s later remark prove it.Curiously, these few pages were omitted from his South American notebooks when they were rebound in 9 volumes at the end of his life. Together with the Berlin State Library autograph collection, these missing pages were relocated during World War II, and for decades they were considered lost. Actually, they are well preserved in the Krakau University Library, where I found them recently. They form a valuable addition to Margot Faak’s edition of Humboldt’s Latin American diaries.This paper discusses the manuscript, showing the development of Humboldt’s opinions in some disciplines he was concerned with. Some of these developments represent paradigmatic changes in natural history, especially in geology.

  6. Lifetime assessment of thick-walled components made of nickel-base alloys under near-service loading conditions; Lebensdauerbewertung dickwandiger Bauteile aus Nickelbasislegierungen unter betriebsnahen Beanspruchungen

    Until 2050 the renewable energies should provide 80% of the power in Germany according to Renewable Energy law. Due to that reason the conventional power plants are not used for base load, but rather for the supply of average and peak load. The change of the operating mode leads to shorter times at stationary temperatures and the number of faster start-ups/shut-downs of the power plants will increase. As a result of this the components are exposed to an interacting load of creep and fatigue which reduces the lifetimes. The aim of this thesis is the development and verification of a lifetime assessment procedure for components made of the nickel-base alloys Alloy 617 mod. and Alloy 263 under creep fatigue loading conditions based on numerical phenomenological models and on the approaches of different standards/recommendations. The focus lies on two components of the high temperature material test rig II (HWT II), a header made of Alloy 617 mod. and Alloy 263 as well as a formed part made of Alloy 617 mod. For the basis characterization of the HWT II melts, specimens of the Alloy 617 mod. and Alloy 263 are tested in uniaxial tensile tests, (creep-)fatigue tests, creep tests and charpy tests in a temperature range between 20 C and 725 C. From the comparisons of the test results and the material specifications respectively the results of the projects COORETEC DE4, MARCKO DE2 and MARCKO700 no deviations were obvious for both materials with the exception of the creep test results with Alloy 617 mod. material. The creep tests with Alloy 617 mod. material of the HWT II melt show differences regarding the deformation and damage behavior. In addition to the basis characterization tests some complex lab tests for the characterization of the material behavior under creep-fatigue and multiaxial loading conditions were conducted. The developments of the microstructure, the precipitations as well as the structure of dislocations are investigated in the light optical microscope

    Biosorption of Pb(II), Cu(II), Cd(II) and Zn(II) from binary metal solutions onto the algae Gelidium sesquipedale, an algal industrial waste and a waste-based composite material was investigated at pH 5.3, in a batch system. Binary Pb(II)/Cu(II), Pb(II)/Cd(II) and Pb(II)/Zn(II) solutions have been tested. For the same equilibrium concentrations of both metal ions (1 mmol l(-1)), approximately 66, 85 and 86% of the total uptake capacity of the biosorbents is taken by lead ions in the systems Pb(II)/Cu(II), Pb(II)/Cd(II) and Pb(II)/Zn(II), respectively. Two-metal results were fitted to a discrete and a continuous model, showing the inhibition of the primary metal biosorption by the co-cation. The model parameters suggest that Cd(II) and Zn(II) have the same decreasing effect on the Pb(II) uptake capacity. The uptake of Pb(II) was highly sensitive to the presence of Cu(II). From the discrete model it was possible to obtain the Langmuir affinity constant for Pb(II) biosorption. The presence of the co-cations decreases the apparent affinity of Pb(II). The experimental results were successfully fitted by the continuous model, at different pH values, for each biosorbent. The following sequence for the equilibrium affinity constants was found: Pb>Cu>Cd approximately Zn.

    It is well known that RTO (regenerative thermal oxidation) systems can purify hydrocarbons effectively and efficiently. A number of experiments carried out in Germany and Austria showed that RTO systems are also suited for purification of composter waste air. The positive results show how the specified limiting values can be achieved. [German] Aus zahlreichen Anwendungen in der Industrie ist bekannt gewesen, dass RTOs (regenerativ thermische Oxidation) in der Lage sind, Kohlenwasserstoffe effektiv und effizient zu reinigen.

    In this diploma thesis two methods are presented, by which {tau} leptons shall be studied in the future data of the ATLAS experiment. The first part is formed by the determination of misidentification rates of jets from QCD 2-jet events as {tau} particles. The second part is the development of a method for the determination of the {tau} reconstruction and identification efficiency relatively to the {mu} efficiency. In this connection invariant masses from Z{yields}ll events are determined, the masses from Z{yields}{tau}{tau} events compared with those from Z{yields}ee and Z{yields}{mu}{mu}, {tau} efficiencies averaged over all ranges and in different {eta} ranges calculated as well as a mehtod for the determination of {tau} efficiencies in different transverse-momentum ranges presented. Furthermore an improved estimation of the QCD background is performed and the behaviour of the {tau} efficiency under regardment of the trigger studied. [German] In dieser Diplomarbeit werden zwei Methoden vorgestellt, mit denen {tau}-Leptonen in den zukuenftigen Daten des ATLAS-Experiments untersucht werden sollen. Den ersten Teil bildet die Bestimmung von Missidentifikationsraten von Jets aus QCD-2-Jet-Ereignissen als {tau}-Leptonen. Der zweite Teil ist die Entwicklung einer Methode zur Bestimmung der {tau}-Rekonstruktions und -Identifikationseffizienz relativ zur {mu}-Effizienz. In diesem Zusammenhang werden invariante Massen aus Z {yields} ll-Ereignissen bestimmt, die Massen aus Z {yields} {tau}{tau}-Ereignissen mit denen aus Z {yields} ee und Z {yields} {mu}{mu} verglichen, {tau}-Effizienzen gemittelt ueber alle Bereiche und in verschiedenen {eta}-Bereichen berechnet sowie eine Moeglichkeit zur Bestimmung von {tau}-Effizienzen in unterschiedlichen Transversalimpulsbereichen vorgestellt. Des Weiteren wird eine verbesserte Abschaetzung des QCD-Untergrunds vorgenommen und das Verhalten der {tau}-Effizienz unter Beruecksichtigung des Triggers untersucht. (orig.)

    Jaundice and colic pain of the right upper quadrant are the main symptoms of biliary diseases. Gallstone-related diseases often lead to hospital admission. The evaluation of a patient with biliary symptoms requires a combination of history taking, physical examination, laboratory analysis, and imaging modalities. A high-quality magnetic resonance imaging (MRI) or computed tomography (CT) scan is usually sufficient to evaluate a patient with painless jaundice. Ultrasonography is helpful as an initial screening test to guide the diagnostic work-up. Invasive methods (e.g., ERCP) are mainly used for palliation of patients with incurable disease. (orig.) [German] Erkrankungen der Gallenwege manifestieren sich mit den beiden Kardinalsymptomen Ikterus und kolikartigen rechtsseitigen Oberbauchschmerzen. Die durch Gallensteine verursachten Beschwerden und Erkrankungen zaehlen zu den haeufigsten gastroenterologischen Krankheitsbildern, die eine Klinikaufnahme erfordern. Die Abklaerung eines Patienten mit biliaeren Symptomen erfolgt durch eine Kombination von Anamnese, Medikamentenanamnese, koerperlicher Untersuchung, Laboranalysen und bildgebenden Verfahren. Bei Patienten mit malignen Tumoren im Bereich der ableitenden Gallenwege reichen in vielen Faellen Computertomographie (CT) oder Magnetresonanztomographie (MRT) zur Abklaerung des schmerzlosen Ikterus aus, um Therapieentscheidungen fuer den Patienten zu faellen. Der Ultraschall ist fuer die Planung der weiteren Diagnostik oft entscheidend. Der Stellenwert invasiver Methoden, wie z. B. der endoskopischen retrograden Cholangio-Pankreatikographie (ERCP), liegt vornehmlich in der Intervention, insbesondere zur Palliation bei Patienten, deren Erkrankung nicht mehr heilbar ist.

[German] In der vorliegenden Arbeit wird in Form einer Systemanalyse untersucht, inwiefern eine Kombination der drei Bereiche energetische Biomassenutzung, Kraft-Waerme-Kopplung (KWK) und CO{sub 2}-Sequestrierung (CCS - Carbon Capture and Storage) grundsaetzlich moeglich und sinnvoll ist. Unter dem Begriff CO{sub 2}-Sequestrierung wird in dieser Arbeit die Prozesskette aus CO{sub 2}-Abscheidung, CO{sub 2}-Transport und CO{sub 2}-Speicherung verstanden. Waehrend die Nutzung von Biomasse in Heizkraftwerken bereits gaengige Praxis darstellt, befindet sich die CO{sub 2}-Sequestrierung (auf Basis fossiler Energietraeger) im Forschungs und Entwicklungsstadium. Eine Kombination von CCS mit Biomasse ist bislang wenig, eine Kombination mit Heizkraftwerken gar nicht untersucht worden. Die beiden Techniken der energetischen Biomassenutzung und der KWK stellen in den Planungen der deutschen Bundesregierung feste Groessen im Energiesystem der Zukunft dar: Nach dem Leitszenario des Bundesumweltministeriums soll die Stromerzeugung aus Biomasse bis 2020 gegenueber 2008 nahezu verdoppelt werden. Gleichzeitig soll die in KWK erzeugte Waerme verdreifacht werden [vgl. Nitsch und Wenzel, 2009, S. 10]1. Parallel dazu soll die CCS-Technologie bis 2030 in der Haelfte aller deutschen Kohlekraftwerke eingesetzt werden [vgl. Krassuki et al., 2009, S. 17]. Auch die Kombination aus Biomasse und CCS stellt fuer die deutsche Bundespolitik eine perspektivisch denkbare Option dar [vgl. Bundestag, 2008b, S. 4]. Darueber hinaus werden der CCS-Technologie zukuenftig sehr gute Exportchancen fuer die deutsche Wirtschaft eingeraeumt [vgl. Bundesregierung, 2010, S. 20]. Die Kombination von Biomasse-Heizkraftwerken mit CCS bietet ueber die CO{sub 2}-Neutralitaet hinaus die interessante Moeglichkeit, als zukuenftiges Klimaschutzinstrument

Os participantes compararam pesos colocados sobre as palmas das mãos e, conforme a condição experimental, podiam movimentar ou não os braços, bem como visualizar ou não suas mãos e os estímulos. Os resultados mostraram que a precisão e a sensibilidade foram influenciadas pelo movimento e, em menor grau, pela visão. Em geral, o movimento leva à maior precisão e mais sensibilidade, e a contribuição da visão ocorreu nas condições sem movimento. O nível de confiança não foi influenciado pelo movimento, mas foi influenciado pela visão, sobretudo nas condições sem movimento. O nível de confiança foi congruente à precisão dos julgamentos somente na ausência de visão, sugerindo um conhecimento implícito da precisão.

Hierzu werden die Daten mit human-/oekotoxikologischen Kenngroessen, Grenz- und Orientierungswerten sowie mit der Hintergrundbelastung verglichen und die inhalative Zusatzbelastung wird berechnet. Diese liegt fuer alle Stoffe im Bereich von 10{sup -9} bis 10{sup -1} Prozent. Eine Ausnahme bilden die Phthalsaeureester mit einem Spitzenwert fuer die Zusatzbelastung von 6,5%. Wenn vorhanden, werden die Emissionsdaten von anderen Verbrennungsprozessen mit in die Einordnung aufgenommen. Von vielen Substanzklassen wird bei einer Abfallverbrennungsanlage, die die Grenzwerte der 17. BImSchV einhaelt, weniger an die Umgebungsluft abgegeben als bei anderen industriellen Prozessen oder z.B. bei der Verbrennung von Kohle oder Holz. (orig.)

    The production of silage is now standard and an important basis for a successful milk and beef production. Silage is also needed in agricultural biogas plants as a substrate for energy production. This publication is intended to serve agriculture as a source of information and guidance document for the construction and operation of silos and the administration as an orientating work aid. The factors influencing the accumulation of silage seepage and the possibilities of prevention in silage and silage management are presented and evaluated from environmental and legal perspective. [German] Die Produktion von Silage ist heute Standard und eine wichtige Grundlage fuer eine erfolgreiche Milch- und Rindfleischerzeugung. Silage wird auch in landwirtschaftlichen Biogasanlagen als Substrat zur Energieerzeugung benoetigt.

Die Einflussgroessen auf den Anfall an Sickersaeften und die Moeglichkeiten der Vermeidung bei der Silierung und dem Silagemanagement werden dargestellt und aus umwelt- und rechtlicher Sicht bewertet.

  19. Solar Type II Radio Bursts and IP Type II Events

    We have examined radio data from the WAVES experiment on the Wind spacecraft in conjunction with ground-based data in order to investigate the relationship between the shocks responsible for metric type II radio bursts and the shocks in front of coronal mass ejections (CMEs). The bow shocks of fast, large CMEs are strong interplanetary (IP) shocks, and the associated radio emissions often consist of single broad bands starting below approx. 4 MHz; such emissions were previously called IP type II events. In contrast, metric type II bursts are usually narrowbanded and display two harmonically related bands. In addition to displaying complete dynamic spectra for a number of events, we also analyze the 135 WAVES 1 - 14 MHz slow-drift time periods in 2001-2003. We find that most of the periods contain multiple phenomena, which we divide into three groups: metric type II extensions, IP type II events, and blobs and bands. About half of the WAVES listings include probable extensions of metric type II radio bursts, but in more than half of these events, there were also other slow-drift features. In the 3 yr study period, there were 31 IP type II events; these were associated with the very fastest CMEs. The most common form of activity in the WAVES events, blobs and bands in the frequency range between 1 and 8 MHz, fall below an envelope consistent with the early signatures of an IP type II event. However, most of this activity lasts only a few tens of minutes, whereas IP type II events last for many hours. In this study we find many examples in the radio data of two shock-like phenomena with different characteristics that occur simultaneously in the metric and decametric/hectometric bands, and no clear example of a metric type II burst that extends continuously down in frequency to become an IP type II event. The simplest interpretation is that metric type II bursts, unlike IP type II events, are not caused by shocks driven in front of CMEs.

Some intermediate complexes have been isolated by temperature arrest technique (pyrolysis) and characterised. Configurational and conformational changes have been studied by elemental analyses, IR and electronic spectra, magnetic moment data (in the case of Ni(II) and Cu(II) complexes) and thermal analysis. E a * , ΔH, and ΔS for the decomposition reaction of these complexes are evaluated and the stability of the complexes with respect to activation energy has also been compared. The linear correlation has been found between E a * and ΔS for the decomposition of the complexes. (author)

  2. Dust in H II regions

    International Nuclear Information System (INIS)

    Isobe, S.

    1977-01-01

    Several pieces of evidence indicate that H II regions may contain dust: 1) the continuum light scattered by dust grains (O'Dell and Hubbard, 1965), 2) thermal radiation from dust grains at infrared wavelengths (Ney and Allen, 1969), 3) the abnormal helium abundance in some H II regions (Peimbert and Costero, 1969), etc. Although observations of the scattered continuum suggest that the H II region cores may be dust-free, dust grains and gas must be well mixed in view of the infrared observations. This difficulty may be solved by introducing globules with sizes approximately 0.001 pc. These globules and the molecular clouds adjacent to H II regions are the main sources supplying dust to H II regions. (Auth.)

    BEPC II-an upgrade project of the Beijing Electron Positron Collider (BEPC) is a factory type of e + e - collider. The fundamental requirements for its injector linac are the beam energy of 1.89 GeV for on-energy injection and a 40 mA positron beam current at the linac end with a low beam emittance of 1.6 μm and a low energy spread of ±0.5% so as to guarantee a higher injection rate (≥50 mA/min) to the storage ring. Since the positron flux is proportional to the primary electron beam power on the target, the authors will increase the electron gun current from 4A to 10A by using a new electron gun system and increase the primary electron energy from 120 MeV to 240 MeV. The positron source itself is an extremely important system for producing more positrons, including a positron converter target chamber, a 12kA flux modulator, the 7m focusing module with DC power supplies and the support. The new positron production linac from the electron gun to the positron source has been installed into the tunnel. In what follows, the authors will emphasize the positron source design, manufacture and tests. (authors)

    The quest for the mysterious missing mass of the universe has become one of the big challenges of today's particle physics and cosmology. Astronomical observations show that only 1% of the matter of the universe is luminous. Moreover there is now convincing evidence that 85% of all gravitationally observable matter in the universe is of a new exotic kind, different from the 'ordinary' matter surrounding us. In a series of three lectures we discuss past, recent and future efforts made world-wide to detect and/or decipher the nature of Dark Matter. In Lecture I we review our present knowledge of the Dark Matter content of the Universe and how experimenters search for it's candidates; In Lecture II we discuss so-called 'direct detection' techniques which allow to search for scattering of galactic dark matter particles with detectors in deep-underground laboratories; we discuss the interpretation of experimental results and the challenges posed by different backgrounds; In Lecture III we take a look at the 'indirect detection' of the annihilation of dark matter candidates in astrophysical objects, such as our sun or the center of the Milky Way; In addition we will have a look at efforts to produce Dark Matter particles directly at accelerators and we shall close with a look at alternative nonparticle searches and future prospects.

    This issue assembles a selection of articles publicly available on the website Ciudades para un Futuro más Sostenible (CF+S: http://habitat.aq.upm.es. This selection was originally used as a printed companion guide to the public lecture series on ‘‘Sustainability in the Architecture and Urban Project’’, held on March 2004 and organized by the Madrid School of Architecture within the Initiative for a more Sustainable Architecture and Urbanism (IAU+S. The compilation an overall vision on sustainability presents to average audience. The basic criterion to select these articles was therefore a pedagogical one, including those simpler and clearer papers dealing with all main topics in CF+S. However, due to space limitations, many excellent articles available on the website are unfortunately not included within this selection. CF+S was created in 1996 as a partnership between the Spanish Ministry of Works and Madrid School of Architecture. The objective was to translate into Spanish and publish the experiences selected at the International Award for Best Practices in Improving the Living Environment, organized by United Nations after the Istanbul Conference on Human Settlements (Habitat II. CF+S aims to gather documents concerning any kind of actions and experiences both on the territory and the city actually improving people’s living conditions according to the sustainability concept in its strongest sense. It also offers papers, reports and theoretical reflections on the state of and the possible alternatives to urban development nowadays.

  7. Crystal Structure of Rat Carnitine Palmitoyltransferase II (CPT-II)

    2006-01-01

    Carnitine palmitoyltransferase II (CPT-II) has a crucial role in the {beta}-oxidation of long-chain fatty acids in mitochondria. We report here the crystal structure of rat CPT-II at 1.9 Angstroms resolution. The overall structure shares strong similarity to those of short- and medium-chain carnitine acyltransferases, although detailed structural differences in the active site region have a significant impact on the substrate selectivity of CPT-II. Three aliphatic chains, possibly from a detergent that is used for the crystallization, were found in the structure. Two of them are located in the carnitine and CoA binding sites, respectively. The third aliphatic chain may mimic the long-chain acyl group in the substrate of CPT-II. The binding site for this aliphatic chain does not exist in the short- and medium-chain carnitine acyltransferases, due to conformational differences among the enzymes. A unique insert in CPT-II is positioned on the surface of the enzyme, with a highly hydrophobic surface. It is likely that this surface patch mediates the association of CPT-II with the inner membrane of the mitochondria.

    The Options Study has been conducted for the purpose of evaluating the potential of alternative integrated nuclear fuel cycle options to favorably address the issues associated with a continuing or expanding use of nuclear power in the United States. The study produced information that can be used to inform decisions identifying potential directions for research and development on such fuel cycle options. An integrated nuclear fuel cycle option is defined in this study as including all aspects of the entire nuclear fuel cycle, from obtaining natural resources for fuel to the ultimate disposal of used nuclear fuel (UNF) or radioactive wastes. Issues such as nuclear waste management, especially the increasing inventory of used nuclear fuel, the current uncertainty about used fuel disposal, and the risk of nuclear weapons proliferation have contributed to the reluctance to expand the use of nuclear power, even though it is recognized that nuclear power is a safe and reliable method of producing electricity. In this Options Study, current, evolutionary, and revolutionary nuclear energy options were all considered, including the use of uranium and thorium, and both once-through and recycle approaches. Available information has been collected and reviewed in order to evaluate the ability of an option to clearly address the challenges associated with the current implementation and potential expansion of commercial nuclear power in the United States. This Options Study is a comprehensive consideration and review of fuel cycle and technology options, including those for disposal, and is not constrained by any limitations that may be imposed by economics, technical maturity, past policy, or speculated future conditions. This Phase II report is intended to be used in conjunction with the Phase I report, and much information in that report is not repeated here, although some information has been updated to reflect recent developments. The focus in this Options Study was to

    The dynamics of a stiffnite are here inferred. A stiffnite is a sheet-shaped, gravity-driven submarine sediment flow, with a fabric made up of marine ooze. To infer stiffnite dynamics, order of magnitude estimations are used. Field deposits and experiments on materials taken from the literature are also used. Stiffnites can be tens or hundreds of kilometers wide, and a few centimeters/ meters thick. They move on the sea slopes over hundreds of kilometers, reaching submarine velocities as high as 100 m/s. Hard grain friction favors grain fragmentation and formation of triboelectrically electrified particles and triboplasma (i.e., ions + electrons. Marine lipids favor isolation of electrical charges. At first, two basic assumptions are introduced, and checked a posteriori: (a in a flowing stiffnite, magnetic dipole moments develop, with the magnetization proportional to the shear rate. I have named those dipoles as Ambigua. (b Ambigua are ‘vertically frozen’ along stiffnite streamlines. From (a and (b, it follows that: (i Ambigua create a magnetic field (at peak, >1 T. (ii Lorentz forces sort stiffnite particles into two superimposed sheets. The lower sheet, L+, has a sandy granulometry and a net positive electrical charge density. The upper sheet, L–, has a silty muddy granulometry and a net negative electrical charge density; the grains of sheet L– become finer upwards. (iii Faraday forces push ferromagnetic grains towards the base of a stiffnite, so that a peak of magnetic susceptibility characterizes a stiffnite deposit. (iv Stiffnites harden considerably during their motion, due to magnetic confinement. Stiffnite deposits and inferred stiffnite characteristics are compatible with a stable flow behavior against bending, pinch, or other macro instabilities. In the present report, a consistent hypothesis about the nature of Ambigua is provided.

    The Rotating Target Neutron Source II facility (RTNS-II) operated for over nine years. Its purpose was to provide high intensities of 14 MeV neutrons for materials studies in the fusion energy program. For the period from 1982-1987, the facility was supported by both the US (Department of Energy) and Japan (Ministry of Education, Culture, and Science). RTNS-II contains two accelerator-based neutron sources which use the T(d,n) 4 He reaction. In this paper, we will summarize the operational history of RTNS-II. Typical operating parameters are given. In addition, a brief description of the experimental program is presented. The current status and future options for the facility are discussed. 7 refs., 5 tabs

    friedlichen Nutzung der Kernenergie in Deutschland an beruecksichtigt. Bereits 1957 wird in einem Memorandum der Deutschen Atomkommission der Hinweis auf die Notwendigkeit der sicheren Beseitigung der radioaktiven Abfaelle formuliert. Der Gesetzgeber hat diese Anregung aufgegriffen und schon im Atomgesetz vom 23.12.1959 Vorschriften zur schadlosen Verwertung radioaktiver Stoffe angelegt. Von der Bundesrepublik wurde in Zusammenhang mit dem Nuklearen Entsorgungszentrum auch nach einem geeigneten Endlagerstandort gesucht. Nach einer intensiven Standortsuche durch die Bundesregierung und das Land Niedersachsen benannte die Niedersaechsische Landesregierung 1977 Gorleben als Standort. Vorausgegangen war ein 3-stufiges Auswahlverfahren, in dem mehr als 140 Standorte betrachtet wurden. Die Arbeiten zur Erkundung des Standortes Gorleben begannen 1979 und wurden am 01.10.2000 zur Klaerung von konzeptionellen und sicherheitstechnischen Zweifeln der Bundesregierung unterbrochen. Vom BMU wird die Verfuegbarkeit eines (Hochaktiv-)Endlagers im Jahr 2030 angestrebt. Aus technischer Sicht ist eine Inbetriebnahme eines Endlagers fuer waermeentwickelnde Abfaelle in Gorleben ab dem Jahr 2025 noch erreichbar, sofern sich der Salzstock nach zuegigem Abschluss der Erkundungsarbeiten als geeignet erweist. Auf die absehbaren Problemfelder wird hingewiesen. Ein weiteres Projekt der Bundesregierung ist die Nutzung der Schachtanlage Konrad als Endlager fuer schwach- und mittelradioaktive Abfaelle. Der Planfeststellungsbeschluss wurde nach gut 20 Jahren im Mai 2002 erteilt und ist zurzeit noch beklagt. Aus den dargestellten Angaben zum erwarteten Abfallvolumen der nicht-waermeentwickelnden EVU-Abfaelle in Verbindung mit dem moeglichen Beginn des Einlagerungsbetriebs Konrad 2013 werden detaillierte Ergebnisse vorgestellt.

    Full Text Available Este trabalho objetivou verificar se o ultrassom de baixa potência (US previne a ocorrência de osteopenia em tíbias de ratos sob ausência de carga. Foram utilizados 45 Rattus novergicus albinus, Wistar adultos, machos, distribuídos em cinco grupos iguais: C - animais-controle livres em gaiolas por 21 dias; S - animais suspensos pela cauda por 21 dias; ST - suspensos pela cauda por 21 dias e concomitantemente tratados com US; S→C - suspensos por 21 dias e depois permanecendo livres em gaiolas por mais 21 dias; S→CT - suspensos por 21 dias e depois permanecendo livres em gaiolas por mais 21 dias e concomitantemente tratados com US. O tratamento foi realizado com US de 1,5MHz, ciclo de trabalho 1:4, 30mW/cm², na tíbia direita, por 15 sessões de 20 minutos cada, cinco sessões por semana. Ainda vivos, os animais foram submetidos a exame de densitometria óssea para verificação da densidade mineral óssea (DMO e do conteúdo mineral ósseo (CMO. Após a eutanásia dos animais, as tíbias foram desarticuladas, dissecadas e submetidas a ensaio mecânico destrutivo para análise da força máxima (Fmáx e da rigidez (R. Foram avaliados também o comprimento (L e o diâmetro (D no ponto médio da tíbia. O grupo S apresentou valores de DMO, CMO, Fmáx, R, L e D menores em relação ao grupo C, demonstrando que a suspensão pela cauda é prejudicial a estas variáveis. O tratamento dos animais suspensos com o US, grupo ST, elevou os valores de CMO e DMO em relação aos do grupo S, igualando-os aos do grupo C. A Fmáx, R e L do grupo ST aumentou em relação ao grupo S e também em relação ao grupo C (p0,05. Os resultados obtidos neste estudo permitem concluir que o US de baixa potência contribuiu na prevenção e reversão da ocorrência da osteopenia nos animais submetidos à suspensão pela cauda, demonstrando que a ausência do estímulo mecânico causada pela impossibilidade da deambulação pode ser minimizada pela ação mec

    Full Text Available O objetivo do presente estudo foi avaliar o efeito de diferentes concentrações de NaCl nas fases de multiplicação e enraizamento in vitro do abacaxizeiro cultivar MD Gold. Brotos de abacaxizeiro foram inoculados em meio MS, na ausência e presença dos fitorreguladores ácido naftalenoacético (ANA e 6-benzilaminopurina (BAP e também de diferentes concentrações de NaCl (Controle - 0; 50; 100 e 150 mM. Mensalmente, os brotos foram subcultivados e foram analisados altura média, número de folhas vivas e mortas, taxas de brotação e enraizamento. Durante a multiplicação e na ausência de ANA e BAP, o NaCl provocou significativa redução no crescimento e desenvolvimento de brotos de abacaxizeiro, expresso pela altura e pelo número de folhas, nas doses mais elevadas, contrariamente, na presença dos fitorreguladores. Durante os 60 dias iniciais, ocorreu aumento na produção de folhas. Contudo, aos 90 dias, observou-se decréscimo na média de folhas vivas nos brotos tratados com sal. O cultivo in vitro de abacaxizeiro em presença de sal é mais eficiente na presença de ANA e BAP, garantindo a manutenção do crescimento, aumentando o número de folhas, produzindo novas gemas e acelerando o processo de enraizamento.To assess the effects of salt on the pineapple MD Gold during the multiplication and rooting phases in vitro, this study evaluated its performance in different concentrations of NaCl in the absence or presence of growth regulators.

    Full Text Available Num experimento conduzido em São Simão (SP durante três anos consecutivos, em um latossolo roxo de textura média, anteriormente sob vegetação de cerrado, estudou-se o efeito da aplicação de fosfato-de-araxá, hiperfosfato, termofosfato (Yoorin e superfosfato triplo em presença e ausência de calagem, sobre o crescimento, produtividade e absorção de nutrientes pela soja cultivar Santa-Rosa. Os dados evidenciaram a importância dos nutrientes acompanhantes de fósforo dos adubos fosfatados, especialmente do cálcio, sobre o crescimento, produção de grãos e absorção de fósforo pela parte aérea da soja. Na presença de calagem, não houve diferença marcante entre os adubos sobre a produtividade e absorção do fósforo. Na sua ausência, os adubos menos solúveis, aplicados em maiores quantidades e, portanto, levando grandes quantidades de cálcio, mostraram efeitos residuais melhores que os fosfatados mais solúveis. A produtividade com a aplicação dos fosfatos menos solúveis no terceiro ano de plantio sem calagem mostrou boa correlação com a absorção de cálcio, magnésio, fósforo e com a relação Ca/Mn das folhas.One experiment was conducted during three successive growing seasons in São Simão, State of São Paulo, Brazil, to test the effect of different phosphates and liming on the uptake of phosphorus by soybeans.

    Full Text Available [english] A great number of learning objects is available for graduate and continuing medical education. Nevertheless, it is not known how well the range of available learning objects covers the needs of the various medical fields. To get an idea of this, the content of two catalogs of learning objects (LRSMed and KELDAmed was compared with the study regulations of the medical faculty of the University of Duisburg-Essen on the one hand and with the 2006 directory of certified medical specialists on the other hand. Spearman’s rank correlation coefficient was used as concordance measure in addition to a qualitative assessment. Correlation coefficients of 0.495 (LRSMed and 0.510 (KELDAmed show a relevant concordance with study regulations, while correlation coefficients of 0.300 and –0.182 reveal a worse concordance with continuing medical education. Therefore, the offers for graduate medical education correspond well with the medical fields, based on number of hours per semester per course. The absolute number of 1,822 learning objects from LRSMed and 1,769 from KELDAmed is excellent as well. The gap for continuing medical education can now be closed by means of funding from professional organizations and medical faculties and through healthcare policies. The quality of the learning objects offered by LRSMed and KELDAmed remains unknown, as there is yet no reliable and valid approach for assessing their quality.

    The author discusses aspects of international harmonization of laws and regulations in this field and describes such activities at the European level and within the EU, and under WTO agreements. (orig./CB) [German] Zur Verwirklichung des Binnenmarktes fuer Lebensmittel kommen nach dem EG-Vertrag Massnahmen der Rechtsangleichung in Betracht (Art. 100a Abs. 1 EGV). Insoweit beruht die Freiheit des Lebensmittelverkehrs im Binnenmarkt auf der gemeinschaftsweiten Harmonisierung der nationalen lebensmittelrechtlichen Regelungen. Ausserhalb dieses harmonisierten Bereichs gewaehrleistet die unmittelbar im EG-Vertrag in Art. 30 verankerte Warenverkehrsfreiheit den freien Verkehr mit Lebensmitteln im gesamten Gebiet der Gemeinschaft. Insoweit folgt aus der Cassis de Dijon-Rechtsprechung des Gerichtshofes der Europaeischen Gemeinschaften (EuGH) das Prinzip der gegenseitigen Anerkennung: Lebensmittel, die in einem anderen Mitgliedstaat rechtmaessig hergestellt oder dort rechtmaessig in Verkehr gebracht worden sind, duerfen grundsaetzlich in jedem anderen Mitgliedsstaat vermarktet werden. Dabei stellt der Schutz der Verbraucher eine vom EuGH bereits in die Gewaehrleistung des freien Warenverkehrs in Art. 30 EGV hineingelesene ('immanente') Schranke dar. Daneben darf der freie Warenverkehr gemaess Art. 36 EGV ausdruecklich auch zum Schutz der menschlichen Gesundheit eingeschraenkt werden. In dem auf der Grundlage des Art. 100a Abs. 1 EGV harmonisierten Bereich des Warenverkehrs soll ein hohes Niveau des Gesundheits- und Verbraucherschutzes verwirklicht werden (vgl. Art. 100a Abs. 3 EGV). Art. 100a EGV wird auch die Kompetenzgrundlage fuer zwei sich ergaenzende EG-Richtlinien ueber die ionisierende Bestrahlung von Lebensmitteln sein, deren Entwuerfe gegenwaertig auf der Ebene der Europaeischen Gemeinschaft beraten werden.

    Co-combustion plants, in which fuel is partly substituted by waste materials, are subject to the 17th BImSchV (Nuisance Control Ordinance) provided that the thermal fraction of 25% is not exceeded. Emission limits are calculated proportionately on the basis of limiting values for emissions from coal power stations (13th BImSchV) and waste incinerators (17th BImSchV). Compared to coal, waste has higher concentrations of heavy metals and halogens, which results in enhanced emissions of heavy metal compounds and chlorides with the flue gas and gasification gas. Plant operators intending to opt for co-combustion must check if the existing flue gas purification system is efficient enough to meet the specifications of the 17th BImSchV. In general, thermodynamic modelling is the most common method of evaluation and optimisation for high-temperature processes of this kind. (orig./SR) [Deutsch] Da bei der Mitverbrennung ein Teil des Brennstoffes durch den Reststoff substituiert wird, unterliegen diese Anlagen der Anteilsregelung nach 17. BImSchV, sofern ein thermischer Anteil von 25% nicht ueberschritten wird. Emissionsgrenzwerte werden anteilig aus den z.B. fuer Kohlekraftwerke gueltigen Grenzwerten nach TA Luft oder 13. BImSchV und denen fuer Abfaelle u.ae. nach 17 BImSchV ermittelt. Der hier betrachtete Reststoff Muell beinhaltet im Vergleich zur Kohle hohe Konzentrationen an Schwermetallen und Halogenen. Dies laesst eine erhoehte Emission von Schwermetallverbindungen und Chloriden mit dem Rauchgas bzw. Vergasungsgas erwarten. Es muss in jedem Fall ueberprueft werden, ob die vorhandene Rauchgasreinigung ausreicht, wenn bei der Mitverbrennung/-vergasung die Emissionsgrenzwerte der 17. BImSchV zur Anwendung kommen. Als Bewertungs- und Optimierungsmethode fuer derartige Hochtemperaturprozesse setzt sich die thermodynamische Modellierung zunehmend durch. (orig./SR)

    2018-04-26

    We discuss injection of 800 MeV proton beam from PIP-II into the production target for Mu2e-II, assuming a targeting and μ production scenario similar to mu2e. The incoming beam trajectory must be modified from the mu2e parameters to match the focusing fields. Adding a vertical deflection at injection enables the injected beam to reach the target. Other differences from the mu2e system must be considered, including changes in the target structure, the radiation shielding and beam dump/absorber. H- beam should be stripped to p+. Other variations are discussed.

    When introducing the amendment to the Act on Renewable Energies (EEG) in August 2004, the legislator changed the remuneration conditions for the production of renewable energy thoroughly, in order to promote especially the energetic utilization of renewable primary products and to create an incentive for the employment of novel technologies. The introduction of the additional bonus payment for power which is exclusively generated from agricultural primary products and residuals has drastically increased the use of energy-generating crops and, as a consequence of a changed substrate situation, the application of novel techniques in the fields of substrate management, plant charging and fermentation. At the same time, the changed general conditions triggered a real boom for the construction of new biogas plants, so that both their number and their size have drastically increased since. The rapid increase in the number of biogas plants that are fuelled on the basis of renewable primary products poses quite a considerable risk for the expansion of the biogas production and utilization in the long run due to a lack of practical experience in many fields. In order to minimize these insecurities, safe information about the state-of-the art technology, the modes of operation and issues concerning the economic efficiency of such plants are urgently required. It is for these reasons that the Fachagentur Nachwachsende Rohstoffe (FNR) promotes a nationwide measurement program for the evaluation of new-type biomass-biogas plants, in order to gain, free from any corporate interests, a fundamental scientific overview over the function, the performance and the weak points of new-type biomass-biogas plants concerned. The information thus gained is also meant to help optimizing the operation of biogas plants with regard to their energy yield, product quality and process stability. (orig.)

    Visual extinction of H II regions in nine nearby galaxies as derived from the ratio of the radio continuum emission to H-alpha emission is systematically larger than visual extinction deduced from the Balmer lines alone, if one assumes a value Av/E(B-V) 3. An optically-limited sample of about 30 extragalactic H II regions has a mean extinction of 1.7 m in the visual while about 1.2 m is not seen in the reddening of the Balmer lines. Both reddening and extinction decreases with increasing galactic radius, at least for M33 and M101

    Room air quality is highly important in Germany as people living here will spend 90 percent of their lives inside rooms. Air quality is defined to a large extent via the nose. This research project, in continuation of AiF 10525, involved investigations of materials and components of space HVAC systems with varying air temperatures, humidities and air flow rates for a subjective assessment of the air quality. The main goals were the definition of laws for identification of odorants and the derivation of laws for calculating pollutant-level-dependent ambient air rates for mechanically ventilated rooms. The experiments showed that both adsorption and desorption had a significant part in the addition of odorangs, causing deviations between theoretical and experimental values of felt air quality. The temperature and the relative humidity had an effect as well. Most measurements were made near the olfactory threshold, so that a number of participants were unable to complete the test. Later investigations will rely on analytical methods in addition to test persons. (orig.) [German] Das Thema der Luftqualitaet in Innenraeumen hat in Deutschland grosse Bedeutung, da sich die Bevoelkerung zu 90 Prozent ihres Lebens in Innenraeumen aufhaelt. Die Behaglichkeit der Atemluft wird in grossem Masse durch die mit der Nase wahrgenommenen Bestandteile der Luft beeinflusst. In Fortsetzung zum Forschungsvorhaben AiF 10525 wurden in diesem Forschungsvorhaben Untersuchungen mit Materialien und Komponenten aus RLT-Anlagen unter Veraenderung von Lufttemperatur, Luftfeuchte und Luftgeschwindigkeit zur subjektiven Beurteilung der Luftqualitaet durchgefuehrt. Die Hauptziele dieser Untersuchungen waren das Auffinden der Gesetzmaessigkeiten zur Wahrnehmung von Geruchsstoffen und das Ableiten von Rechenregeln zur Bestimmung verunreinigungslastabhaengiger Aussenluftraten fuer maschinell belueftete Raeume.

    Because of the increasing number of wind energy plants, environmental protection gets into a conflict of aims. On the one hand the change of the `Stromeinspeisungsgesetz` (law arranging the insertion of privately produced electricity into the public system) and the improved support for wind energy plants is to appreciate for the reasons of a reduction of CO{sub 2} and other harmful substances. But on the other hand wind energy plants have negative environmental effects onto the sites they are built on, as for example disturbances of the birds their breeding nest and feeding habitat, injury or death following collision with a blade or tower or simply disturbances of the landscape view. To avoid possible conflicts and increase the acceptance of wind energy plants, for the district of Soest a concept on a strategic level was developed, in which sites were determined as optimal, restrictional or excluding the construction of wind energy plants. This concept may not only help to avoid conflicts but may also play an active part in the promotion of wind energy plants by defining the sites suitable for wind energy plants and making them public. All in all the procedure of approval was simplified and therefore accelerated with the invention of this concept. (orig.) [Deutsch] Durch die zunehmende Anzahl von Windkraftanlagen geraet der Umweltschutz in einen Zielkonflikt. Einerseits ist die Aenderung des Stromeinspeisungsgesetzes und die verbesserte Foerderung fuer Windkraftanlagen aus Gruenden der CO{sub 2} und Schadstoffemissionseinsparungen sehr zu begruessen.

    Full Text Available Im Rahmen eines Seminars an der HTW Chur wurden Möglichkeiten und Grenzen von Bibliothekspolitik in der Schweiz erläutert. Ausgehend von wenigen Fällen, bei denen es zu Protesten oder anderen Aktivitäten gekommen ist, wurden Akteurinnen und Akteure und ihr Einfluss untersucht, mögliche politische Instrumente analysiert und diskutiert, wie sich Bibliotheken aktiv beteiligen können. Im Ergebnis stellte sich heraus, dass Netzwerke in die Gesellschaft und die Politik von grosser Bedeutung sind. Im Falle eines Konflikts (Budgetkürzung, geplante Schliessung etc. kann sich dieses Netzwerk mit Hilfe der geeigneten politischen Instrumente für die Bibliothek einsetzen. Die Mobilisierung der Bevölkerung, die in den untersuchten Fällen klar auf der Seite der Bibliotheksanliegen war, ist dabei ein entscheidender Erfolgsfaktor.

    Full Text Available Heterotopia are spatial challenges to social order. They are energized not only by real spatial conditions but also by established ascriptions. The example of Venice displays the entanglement and efficacy of the interplay between a specific spatial order and venerable images. The aesthetic realization of the image of the city in Rilke’s New Poems (“Venice Morning” (1908, “The Courtesan” (1907 and in Madonna’s music video “Like a Virgin” (1984 accentuates the manner in which city space is related to the female body and proves once more the importance of using a conscious approach to Foucault’s concept of heterotopia.

    The temperature in the interior of the earth increases with the depth. But for a long time, the geothermal energy only could be used at selected locations. Therefore, almost all major geothermal power plants are located at volcanic regions. The potential of the geothermal energy is not exhausted. Currently, many new power plants are developed. Although there is no volcanic activity in Germany, also some pilot plants develop the hot surface. The deep geothermal energy sometimes is difficult to be controlled. Before drilling experts rarely know how productive the subsoil is. Also, the drillings may trigger small earthquakes.

    This report documents the history of the major buildings in Sandia National Laboratories` Technical Area II. It was prepared in support of the Department of Energy`s compliance with Section 106 of the National Historic Preservation Act. Technical Area II was designed and constructed in 1948 specifically for the final assembly of the non-nuclear components of nuclear weapons, and was the primary site conducting such assembly until 1952. Both the architecture and location of the oldest buildings in the area reflect their original purpose. Assembly activities continued in Area II from 1952 to 1957, but the major responsibility for this work shifted to other sites in the Atomic Energy Commission`s integrated contractor complex. Gradually, additional buildings were constructed and the original buildings were modified. After 1960, the Area`s primary purpose was the research and testing of high-explosive components for nuclear weapons. In 1994, Sandia constructed new facilities for work on high-explosive components outside of the original Area II diamond-shaped parcel. Most of the buildings in the area are vacant and Sandia has no plans to use them. They are proposed for decontamination and demolition as funding becomes available.

    Since its inception almost 8 years ago, NASA's Short-term Prediction Research and Transition (SPoRT) Center has integrated NASA data into the National Weather Service's decision support system (DSS) the Advanced Weather Interactive Processing System (AWIPS). SPoRT has, in some instances, had to shape and transform data sets into various formats and manipulate configurations to visualize them in AWIPS. With the advent of the next generation of DSS, AWIPS II, developers will be able to develop their own plugins to handle any type of data. Raytheon is developing AWIPS II to be a more extensible package written mainly in Java, and built around a Service Oriented Architecture. A plugin architecture will allow users to install their own code modules, and (if all the rules have been properly followed) they will work hand-in-hand with AWIPS II as if it were originally built in. Users can bring in new datasets with existing plugins, tweak plugins to handle a nuance or desired new functionality, or create an entirely new visualization layout for a new dataset. SPoRT is developing plugins to ensure its existing NASA data will be ready for AWIPS II when it is delivered, and to prepare for the future of new instruments on upcoming satellites.

    Fermions--elementary particles such as electrons--are classified as Dirac, Majorana or Weyl. Majorana and Weyl fermions had not been observed experimentally until the recent discovery of condensed matter systems such as topological superconductors and semimetals, in which they arise as low-energy excitations. Here we propose the existence of a previously overlooked type of Weyl fermion that emerges at the boundary between electron and hole pockets in a new phase of matter. This particle was missed by Weyl because it breaks the stringent Lorentz symmetry in high-energy physics. Lorentz invariance, however, is not present in condensed matter physics, and by generalizing the Dirac equation, we find the new type of Weyl fermion. In particular, whereas Weyl semimetals--materials hosting Weyl fermions--were previously thought to have standard Weyl points with a point-like Fermi surface (which we refer to as type-I), we discover a type-II Weyl point, which is still a protected crossing, but appears at the contact of electron and hole pockets in type-II Weyl semimetals. We predict that WTe2 is an example of a topological semimetal hosting the new particle as a low-energy excitation around such a type-II Weyl point. The existence of type-II Weyl points in WTe2 means that many of its physical properties are very different to those of standard Weyl semimetals with point-like Fermi surfaces.

    2008-01-01

    The present study is targeted on solar photocatalytic removal of metal ions from wastewater. Photoreductive deposition and dark adsorption of metal ions Cu(II), Ni(II), Pb(II) and Zn(II), using solar energy irradiated TiO 2 , has been investigated. Citric acid has been used as a hole scavenger. Modeling of metal species has been performed and speciation is used as a tool for discussing the photodeposition trends. Ninety-seven percent reductive deposition was obtained for copper. The deposition values of other metals were significantly low [nickel (36.4%), zinc (22.2%) and lead (41.4%)], indicating that the photocatalytic treatment process, using solar energy, was more suitable for wastewater containing Cu(II) ions. In absence of citric acid, the decreasing order deposition was Cu(II) > Ni(II) > Pb(II) > Zn(II), which proves the theoretical thermodynamic predictions about the metals

    1979-01-01

    Within the frame of this study the pepsinogen II concentration could be determined for the first time with a radioimmunoassay in the plasma. In our normal study group the mean value was 13.91 ng/ml with a variation between 4.08 and 36.19 ng/ml. With increasing patient age a continuous increase of this concentration could be observed. The mean value of 14.99 ng/ml for male patients was by 4.75 ng/ml higher than the mean value of 10.24 ng/ml for female patients. The 24 hour profiles represented for the pepsinogen plasma concentration daily physiologic fluctuations and a stabilisation at night. The effects of meals could not be defined unambiguously. In stimulation tests Pentagastrin provoked in 4 of 9 test persons an increase of the concentration of up to 70% of the basic value. In short-term stress-tests the Pg II concentrations found in the test subjects presented an increase or a decrease. In investigations before or after the same patient underwent an operative procedure, an expressive Pg II decrease (up to 33.74 ng/ml) could be detected. Patients with a total resection of the stomach had only a very low Pg II concentration (less than 3.1 ng/ml). In patients with gastric pathologies a significant difference of the confidence limits was found for the Pg II concentration between superficial gastritis (m = 16.04 ng/ml) and atrophic gastritis (m = 27.38 ng/ml). Compared with various gastric diseases the normal patient group presents a significant difference with reference to the atrophic gastritis or the cancerous stomach. The mean values found in atrophic gastritis or the cancerous stomach. The mean values found in atrophic gastritis and in gastric carcinoma are close to each other and are increased, compared to those measured in the normal patient group. (orig./MG) [de

    Full Text Available Mn(II, Fe(II, Co(II, Ni(II, Cu(II, Zn(II, and Cd(II complex of N-thiophenoyl -N′-phenylthiocarbohydrazide (H2 TPTH have been synthesized and characterized by elemental analysis, magnetic susceptibility measurements, infrared, NMR, electronic, and ESR spectral studies. The complexes were found to have compositions [Mn(H TPTH2], [Co(TPTH (H2O2], [Ni(TPTH (H2O2], [Cu(TPTH], [Zn(H TPTH], [Cd(H TPTH2], and [Fe(H TPTH2(EtOH]. The magnetic and electronic spectral studies suggest square planar geometry for [Cu(TPTH], tetrahedral geometry for [Zn(TPTH] and [Cd(H TPTH2], and octahedral geometry for rest of the complexes. The infrared spectral studies of the 1 : 1 deprotonated complexes suggest bonding through enolic oxygen, thiolato sulfur, and both the hydrazinic nitrogens. Thus, H2TPTH acts as a binegative tetradentate ligand. H2 TPTH and its metal complexes have been screened against several bacteria and fungi.

    The adsorption of Pb(II), Cu(II), Cd(II), Zn(II), Ni(II), Fe(II) and As(V) onto bacterially produced metal sulfide (BPMS) material was investigated using a batch equilibrium method. It was found that the sulfide material had adsorptive properties comparable with those of other adsorbents with respect to the specific uptake of a range of metals and, the levels to which dissolved metal concentrations in solution can be reduced. The percentage of adsorption increased with increasing pH and adsorbent dose, but decreased with increasing initial dissolved metal concentration. The pH of the solution was the most important parameter controlling adsorption of Cd(II), Cu(II), Fe(II), Ni(II), Pb(II), Zn(II), and As(V) by BPMS. The adsorption data were successfully modeled using the Langmuir adsorption isotherm. Desorption experiments showed that the reversibility of adsorption was low, suggesting high-affinity adsorption governed by chemisorption. The mechanism of adsorption for the divalent metals was thought to be the formation of strong, inner-sphere complexes involving surface hydroxyl groups. However, the mechanism for the adsorption of As(V) by BPMS appears to be distinct from that of surface hydroxyl exchange. These results have important implications to the management of metal sulfide sludge produced by bacterial sulfate reduction.

    We present an analysis of observed trends and correlations between a large range of spectral and photometric parameters of more than 100 type II supernovae (SNe II), during the photospheric phase. We define a common epoch for all SNe of 50 days post-explosion, where the majority of the sample is likely to be under similar physical conditions. Several correlation matrices are produced to search for interesting trends between more than 30 distinct light-curve and spectral properties that characterize the diversity of SNe II. Overall, SNe with higher expansion velocities are brighter, have more rapidly declining light curves, shorter plateau durations, and higher 56Ni masses. Using a larger sample than previous studies, we argue that “Pd”—the plateau duration from the transition of the initial to “plateau” decline rates to the end of the “plateau”—is a better indicator of the hydrogen envelope mass than the traditionally used optically thick phase duration (OPTd: explosion epoch to end of plateau). This argument is supported by the fact that Pd also correlates with s 3, the light-curve decline rate at late times: lower Pd values correlate with larger s 3 decline rates. Large s 3 decline rates are likely related to lower envelope masses, which enables gamma-ray escape. We also find a significant anticorrelation between Pd and s 2 (the plateau decline rate), confirming the long standing hypothesis that faster declining SNe II (SNe IIL) are the result of explosions with lower hydrogen envelope masses and therefore have shorter Pd values. This paper includes data gathered with the 6.5 m Magellan Telescopes located at Las Campanas Observatory, Chile; and the Gemini Observatory, Cerro Pachon, Chile (Gemini Program GS- 2008B-Q-56). Based on observations collected at the European Organisation for Astronomical Research in the Southern Hemisphere, Chile (ESO Programs 076.A-0156, 078.D-0048, 080.A-0516, and 082.A-0526).

    Full Text Available The complexes of Mn(II, Co(II, Ni(II, Cu(II and Zn(II with 3,4,5-trimethoxybenzoic acid anion of the formula: M(C10H11O52·nH2O, where n = 6 for Ni(II, n = 1 for Mn(II, Co(II, Cu(II, and n = 0 for Zn, have been synthesized and characterized by elemental analysis, IR spectroscopy, X–ray diffraction measurements, thermogravimetry and magnetic studies. They are crystalline compounds characterized by various symmetry. They decompose in various ways when heated in air to 1273 K. At first, they dehydrate in one step and form anhydrous salts. The final products of decomposition are oxides of the respective metals (Mn2O3, Co3O4, NiO, CuO, ZnO. The solubilities of the analysed complexes in water at 293 K are in the orders of 10-2 – 10-4 mol dm-3. The magnetic susceptibilities of the Mn(II, Co(II, Ni(II and Cu(II complexes were measured over the range of 76–303 K and the magnetic moments were calculated. The results show that the 3,4,5-trimethoxybenzoates of Mn(II, Co(II and Ni(II are high-spin complexes but that of Cu(II forms a dimer [Cu2(C10H11O54(H2O2]. The carboxylate groups bind as monodentate or bidentate chelating or bridging ligands.

  4. TAF(II)250: a transcription toolbox.

    2001-08-01

    Activation of RNA-polymerase-II-dependent transcription involves conversion of signals provided by gene-specific activator proteins into the synthesis of messenger RNA. This conversion requires dynamic structural changes in chromatin and assembly of general transcription factors (GTFs) and RNA polymerase II at core promoter sequence elements surrounding the transcription start site of genes. One hallmark of transcriptional activation is the interaction of DNA-bound activators with coactivators such as the TATA-box binding protein (TBP)-associated factors (TAF(II)s) within the GTF TFIID. TAF(II)250 possesses a variety of activities that are likely to contribute to the initial steps of RNA polymerase II transcription. TAF(II)250 is a scaffold for assembly of other TAF(II)s and TBP into TFIID, TAF(II)250 binds activators to recruit TFIID to particular promoters, TAF(II)250 regulates binding of TBP to DNA, TAF(II)250 binds core promoter initiator elements, TAF(II)250 binds acetylated lysine residues in core histones, and TAF(II)250 possesses protein kinase, ubiquitin-activating/conjugating and acetylase activities that modify histones and GTFs. We speculate that these activities achieve two goals--(1) they aid in positioning and stabilizing TFIID at particular promoters, and (2) they alter chromatin structure at the promoter to allow assembly of GTFs--and we propose a model for how TAF(II)250 converts activation signals into active transcription.

    The Belle II experiment at the SuperKEKB collider in Japan is designed to indirectly probe new physics using approximately 50 times the data recorded by its predecessor. An accurate determination of the decay-point position of subatomic particles such as beauty and charm hadrons as well as a precise measurement of low-momentum charged particles will play a key role in this pursuit. These will be accomplished by an inner tracking device comprising two layers of pixelated silicon detector and four layers of silicon vertex detector based on double-sided microstrip sensors. We describe herein the design, prototyping and construction efforts of the Belle-II silicon vertex detector.

    2016-07-01

    The GERDA experiment is designed to search for neutrinoless double beta (0νββ) decay of {sup 76}Ge. In Phase I of the experiment a background index (BI) of 10{sup -2} cts/(keV.kg.yr) was reached. No signal has been found and a lower limit on the half-life of 2.1.10{sup 25} yr (at 90% C.L.) is extracted. The aim of Phase II is to double the Ge mass and further reduce the BI by an order of magnitude to explore half-lives of about 10{sup 26} yr. Thirty new Broad Energy Germanium (BEGe) detectors have been produced. These detectors are distinct for their improved energy resolution and enhanced pulse shape discrimination of signal from background events. Further background reduction will be reached by an active veto to read out argon scintillation light. The Phase II commissioning showed that two of the major background components, external γ-rays from {sup 214}Bi and {sup 208}Tl decays, can be suppressed up to two orders of magnitude. This talk presents the current status of the GERDA Phase II upgrade.

    The Gossamer Albatross II is seen here during a test flight at NASA's Dryden Flight Research Center, Edwards, California. The original Gossamer Albatross is best known for completing the first completely human powered flight across the English Channel on June 12, 1979. The Albatross II was the backup craft for the Channel flight. It was fitted with a small battery-powered electric motor and flight instruments for the NASA research program in low-speed flight. NASA completed its flight testing of the Gossamer Albatross II and began analysis of the results in April, 1980. During the six week program, 17 actual data gathering flights and 10 other flights were flown here as part of the joint NASA Langley/Dryden flight research program. The lightweight craft, carrying a miniaturized instrumentation system, was flown in three configurations; using human power, with a small electric motor, and towed with the propeller removed. Results from the program contributed to data on the unusual aerodynamic, performance, stability, and control characteristics of large, lightweight aircraft that fly at slow speeds for application to future high altitude aircraft. The Albatross' design and research data contributed to numerous later high altitude projects, including the Pathfinder.

  17. Light echoes - Type II supernovae

    International Nuclear Information System (INIS)

    Schaefer, B.E.

    1987-01-01

    Type II supernovae (SNs) light curves show a remarkable range of shapes. Data have been collected for the 12 Type II SNs that have light curve information for more than four months past maximum. Contrary to previous reports, it is found that (1) the decay rate after 100 days past maximum varies by almost an order of magnitude and (2) the light curve shapes are not bimodally distributed, but actually form a continuum. In addition, it is found that the extinctions to the SNs are related to the light curve shapes. This implies that the absorbing dust is local to the SNs. The dust is likely to be part of a circumstellar shell emitted by the SN progenitor that Dwek (1983) has used to explain infrared echoes. The optical depth of the shell can get quite large. In such cases, it is found that the photons scattered and delayed by reflection off dust grains will dominate the light curve several months after peak brightness. This light echo offers a straightforward explanation of the diversity of Type II SN light curves. 22 references

    Full Text Available The purpose of this study was to determine the concentrations of heavy metals (Cd, Pb, Cu, Mn, and Zn in different organs (liver, kidney, muscle, lung, skin, and feathers of buzzards (Buteo buteo, utilized as a “biological indicator” for environmental contamination, from different areas of Sicily and to investigate the relationships between birds sex, age, and weight and metal levels in these samples. All samples of common buzzards were collected at the “Recovery Center of Wild Fauna” of Palermo, through the Zooprophilactic Institute. Potentiometric stripping analysis (PSA was used to determine the content of Cd(II, Cu(II, Mn(II, Pb(II, and Zn(II in bird tissues. For toxic metals, the highest levels of Pb were in liver and those of Cd in lung; Zn levels were higher than Cu and Mn in all tissues analyzed. The concentrations in liver, lung, kidney, and muscle could be considered as an indicative of chronic exposure to metals while the presence of metals in skin could be consequential to storing and elimination processes. The found concentrations of metals in the studied matrices required a highly sensitive method for their determination and a simple sample preparation procedure, and the proposed method was well suited for this purpose.

    The coordination characteristic of new N4-morpholinyl isatin-3-thiosemicarbazone (HL) towards Co(II), Ni(II), Cu(II), Zn(II) and Pd(II) has been studies. The structures of the complexes were described by elemental analyses, molar conductivity, magnetic, thermal and spectral (IR, UV-Vis, 1H and 13C NMR and ESR) studies. On the basis of analytical and spectral studies the ligand behaves as monobasic tridentate ONS donor forming two five membered rings towards cobalt, copper and palladium and afforded complexes of the kind [M(L)X], (Mdbnd Co, Cu or Pd; Xdbnd Cl, Br or OAc). Whereas the ligand bound to NiCl2 as neutral tridentate ONS donor and with ZnCl2 as neutral bidentate NS donor. The newly synthesized thiosemicarbazone ligand and some of its complexes were examined for antimicrobial activity against 2 gram negative bacterial strains (Escherichia coli Pseudomonas and aeruginosa), 2 gram positive bacterial strains (Streptococcus pneumoniae and Staphylococcus aureus)} and two Pathogenic fungi (Aspergillus fumigatus and Candida albicans). All metal complexes possess higher antimicrobial activity comparing with the free thiosemicarbazone ligand. The high potent activities of the complexes may arise from the coordination and chelation, which tends to make metal complexes act as more controlling and potent antimicrobial agents, thus hindering the growing of the microorganisms. The antimicrobial results also show that copper bromide complex is better antimicrobial agent as compared to the Schiff base and its metal complexes.

    Full Text Available Background: Heavy metals have been recognized as harmful environmental pollutant known to produce highly toxic effects on different organs and systems of both humans and animals. The aim of this paper is to evaluate the adsorption potential of chitosan for the removal of Pb(II, Fe(II and Cu(II ions from aqueous solutions. Methods: This study was conducted in laboratory scale. In this paper chitosan has been used as an adsorbent for the removal of Pb(II, Fe(II and Cu(II from aqueous solution. In batch tests, the effects of parameters like pH solution (1.0-8.0, initial metal concentrations (100-1000 mgL-1, contact time (5.0-150 min and adsorbent dose (1.0-7.0 g on the adsorption process were studied. Results: The results showed that the adsorption of Pb(II, Fe(II and Cu(II ions on chitosan strongly depends on pH. The experimental isothermal data were analyzed using the Langmuir and Freundlich equations and it was found that the removal process followed the Langmuir isotherm and maximum adsorption capacity for the adsorption of Pb(II, Fe(II and Cu(II ions by the chitosan were 55.5mg g−1, 71.4 mg g−1 and 59 mg g−1, respectively, under equilibrium conditions at 25±1 ºC. The adsorption process was found to be well described by the pseudo-second-order rate model. Conclusion: The obtained results showed that chitosan is a readily, available, economic adsorbent and was found suitable for removing Pb(II, Fe(II and Cu(II ions from aqueous solution.

Performance loss is only temporary, if the operating conditions aren't fulfilled. (orig.) [German] Bei kommunalen Klaeranlagen mit anaerober Schlammbehandlung faellt bei der Entwaesserung des stabilisierten Schlammes stark ammoniumhaltiges Prozesswasser an. Die Mitbehandlung dieses Teilstroms aus der Schlammbehandlung in der Hauptstrombiologie der Klaeranlage kann zu einer Erhoehung der Stickstoffbelastung von bis zu 20% fuehren. Eine separate Behandlung von Prozesswaessern kann die Stickstoff-Ablaufwerte verbessern und schafft Reserven in der Hauptstrombiologie. Die autotrophe Denitrifikation nach vorangegangener Teilnitritation in Tropfkoerpern ist ein neuartiges Verfahren zur Behandlung hoch ammoniumhaltiger Abwaesser. Hierzu werden in einem ersten Tropfkoerper etwa 60% des Ammoniums zu Nitrit umgewandelt, wobei die Nitratation gehemmt wird. In einem zweiten geschlossenen Tropfkoerper wird das Ammonium unter anoxischen Bedingungen, mit Nitrit als Elektronenakzeptor, zu molekularem Stickstoff oxidiert. Dieses Verfahren wurde erstmals im grosstechnischen Betrieb auf der Klaeranlage Sindelfingen realisiert. Die Untersuchungen zeigten, dass bereits wenige mg/l Ammoniak im ersten Reaktor ausreichten, um die Nitratation zu hemmen. Da die Nitratation nach einem Anstieg und dem darauffolgenden Abfallen der Ammoniakkonzentration zunahm, fand offensichtlich eine Adaption der Biomasse an die hoeheren Ammoniakgehalte statt. Deshalb sollte die Ammoniakkonzentration moeglichst konstant gehalten und groessere Schwankungen ueber eine laengere Zeit vermieden werden. Nur mit der thermischen Abtoetung der Mikroorganismen und dem erneuten Einfahren des Prozesses konnte nach einer Adaption wieder eine vollstaendige Nitratationshemmung bei geringen Ammoniakkonzentrationen gewaehrleistet werden.

    tartarugas provenientes do litoral do estado de São Paulo, Brasil, sendo 18 sem fibropapilomas e 27 acometidas. Dados de biometria das tartarugas, quantidade, localização e tamanho dos tumores foram anotados. Foi realizado o cálculo da área de fibropapilomas por animal e foram estipulados 4 grupos de acordo com o grau de acometimento e sua ausência. O objetivo foi realizar uma comparação entre os hemogramas das tartarugas marinhas classificadas nos 4 grupos. Animais de grau grave apresentaram o menor valor para hematócrito. Para dosagem de hemoglobina, observou-se que o maior valor foi para o grupo de tartarugas sem fibropapilomas e o menor para o de grau grave. Os valores de linfócitos e comprimento curvilíneo da carapaça beiraram a significância estatística.

    Herein we report a detailed investigation of the complexation properties of the macrocyclic decadentate receptor N,N'-Bis[(6-carboxy-2-pyridil)methyl]-4,13-diaza-18-crown-6 (H(2)bp18c6) toward different divalent metal ions [Zn(II), Cd(II), Pb(II), Sr(II), and Ca(II)] in aqueous solution. We have found that this ligand is especially suited for the complexation of large metal ions such as Sr(II) and Pb(II), which results in very high Pb(II)/Ca(II) and Pb(II)/Zn(II) selectivities (in fact, higher than those found for ligands widely used for the treatment of lead poisoning such as ethylenediaminetetraacetic acid (edta)), as well as in the highest Sr(II)/Ca(II) selectivity reported so far. These results have been rationalized on the basis of the structure of the complexes. X-ray crystal diffraction, (1)H and (13)C NMR spectroscopy, as well as theoretical calculations at the density functional theory (B3LYP) level have been performed. Our results indicate that for large metal ions such as Pb(II) and Sr(II) the most stable conformation is Δ(δλδ)(δλδ), while for Ca(II) our calculations predict the Δ(λδλ)(λδλ) form being the most stable one. The selectivity that bp18c6(2-) shows for Sr(II) over Ca(II) can be attributed to a better fit between the large Sr(II) ions and the relatively large crown fragment of the ligand. The X-ray crystal structure of the Pb(II) complex shows that the Δ(δλδ)(δλδ) conformation observed in solution is also maintained in the solid state. The Pb(II) ion is endocyclically coordinated, being directly bound to the 10 donor atoms of the ligand. The bond distances to the donor atoms of the pendant arms (2.55-2.60 Å) are substantially shorter than those between the metal ion and the donor atoms of the crown moiety (2.92-3.04 Å). This is a typical situation observed for the so-called hemidirected compounds, in which the Pb(II) lone pair is stereochemically active. The X-ray structures of the Zn(II) and Cd(II) complexes show that

    NSLS-II, the new 3rd generation light source at BNL was designed for a brightness of 1022 photons s-1mm-2mrad-2 (0.1%BW)-1. It was constructed between 2009 and 2014. The storage ring was commissioned in April 2014 which was followed by insertion device and beamline commissioning in the fall of 2014. All ambitious design parameters of the facility have already been achieved except for commissioning the full beam intensity of 500mA which requires more RF installation. This paper reports on the results of commissioning.

    A reference design for the 32-GeV LAMPF II proton accelerator is proposed. This design consists of a 30-Hz rapid-cycling synchrotron with a dc stretcher. A superiodicity 5 design with dispersion-free straight sections is suggested for both machines. Beam-dynamics calculations are partially complete and rf requirements are given. Apertures are calculated for 2 x 10 13 protons per pulse (100 μA average current). No significant problems are observed at any time in the cycle in a longitudinal beam-dynamics simulation including space charge

  2. Pep for PEP-II

    The major B-factory project at the Stanford Linear Accelerator Center have(SLAC) is well underway and moving along smartly, en route to commencement of operations in September 1998. Called PEP-II, the new facility is a joint venture of three California laboratories: Lawrence Berkeley Laboratory (LBL), Lawrence Livermore Laboratory (LLNL) and SLAC. Housed at SLAC in the tunnels and buildings built for the original PEP electron-positron collider in the late 1970s, it involves no conventional civil engineering. In fact, PEP-II is a recycling project in more ways than one: for example, most of the original PEP magnets have been renovated for reuse in the PEP-II high-energy ring. While some of them require substantial rework (to change their length, for instance), many of them merely require repainting and remeasuring. The work of building the hardware is divided up among the three laboratories. LBL is primarily responsible for the low-energy ring; LLNL is building most of the interaction region, the complicated part where the high and low energy rings come together; and SLAC is responsible for the rest. Proposed by President Clinton as a ''presidential initiative'' (December 1993, page 2), the project was given a four-year funding profile. The total cost of $177 million, excluding the BaBar detector (September, page 16), was planned by the US government to be entirely provided during the present administration, the last increment coming in the final quarter of 1997. Happily, the first two increments have been forthcoming as planned and the third is faring well in US Congress. The PEP-II design is based on two intersecting storage rings, one carrying 9 GeV electrons and the other 3.1 GeV positrons, operating with high beam currents (a few amperes) to produce a luminosity of 3 x 10 33 per sq cm per s. The asymmetry in the energies of the colliding particles means that the centre-ofmass of the electron-positron annihilation system moves rapidly in the

This facility will complete construction in June 1998. The high energy ring, completed in May 1997, has had 3 months of commissioning and successfully stored 0.75 A of electrons. The success of the high energy ring testing validates not only its ring components, but also the injection system, the RF system and the control system all of which are common to the two rings

    The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S) events in its decade of operation. Super-KEKB, an upgrade of KEKB is under construction, to increase the luminosity by two orders of magnitude during a three-year shutdown, with an ultimate goal of 8E35 /cm^2 /s luminosity. To exploit the increased luminosity, an upgrade of the Belle detector has been proposed. A new international collaboration Belle-II, is being formed. The Technical Design Report presents physics motivation, basic methods of the accelerator upgrade, as well as key improvements of the detector.

    In this study, poly(glycidyl methacrylate-methyl methacrylate-divinylbenzene) was synthesized in the form of microspheres, and then functionalized by 2-aminobenzothiazole ligand. The sorption properties of these functionalized microspheres were investigated for separation, preconcentration and determination of Al(III), Fe(II), Co(II), Cu(II), Cd(II) and Pb(II) ions using flame atomic absorption spectrometry. The optimum pH values for quantitative sorption were 2 - 4, 5 - 8, 6 - 8, 4 - 6, 2 - 6 and 2 - 3 for Al(III), Fe(II), Co(II), Cu(II), Cd(II) and Pb(II), respectively, and also the highest sorption capacity of the functionalized microspheres was found to be for Cu(II) with the value of 1.87 mmol g -1 . The detection limits (3σ; N = 6) obtained for the studied metals in the optimal conditions were observed in the range of 0.26 - 2.20 μg L -1 . The proposed method was successfully applied to different beverage samples for the determination of Al(III), Fe(II), Co(II), Cu(II), Cd(II) and Pb(II) ions, with the relative standard deviation of <3.7%.

    By means of isolated hepatocytes from rainbow trout (Oncorhyuchus myskiss), the reference substances 4-chloro-aniline, 2,4-dichlorophenol, dinitro-o-cresol and 4-nitrophenol, the pesticides atrazine and disulfotone, the ichthyotherapeutic malachite green, and landfill leachates were studied for their toxic effect. As new endpoints, ultrastructural and enzyme-biochemical parameters were established, which are suitable as a sensitive test system for acute, subacute, and sublethal pollutant effects. In comparison with conventional toxicity tests, ultrastructural and biochemical studies represent the currently most sensitive methods for demonstrating the (eco-) toxicological potential of pollutants. In all experiments, clear time-effect and dose-effect relationships could be made out. Isolated hepatocytes from the liver of rainbow trout reacted more sensitively than the permanent cell lines R1 and RTG-2 investigated in parallel. In cytotoxicity tests with the fibrocytic fish cell lines R1 and RTG-2 from the liver or gonad of rainbow trout, cytotoxicity data for various organic pollutants and organic and inorganic heavy metal compounds were acquired. The results form the basis of a concept for assessing the ecotoxicological potential of environmental pollutants by means of multi-stage cell tests, which is described in the paper. (orig./VHE) [Deutsch] Mit isolierten Hepatocyten aus Regenbogenforellen (oncorhyuchus myskiss) wurden die Referenzsubstanzen 4-Chloranilin, 2,4-Dichlorphenol, Dinitro-o-kresol und 4-Nitrophenol, die Pestizide Atrazin und Disulfoton, das Fischtherapeutikum Malachitgruen sowie Deponiesickerwaesser auf toxische Wirkungen untersucht. Als neuer Endpunkt wurden ultrastrukturelle und enzymbiochemische Parameter ermittelt, die sich als empfindliches Nachweissystem fuer akute, subakute und subletale Schadstoffwirkungen eignen. Im Vergleich mit konventionellen Toxizitaetstests stellen ultrastrukturelle und biochemischen Studien die derzeit empfindlichsten

    As originally designed and operated, EBR-II successfully demonstrated the concept of a sodium-cooled fast breeder power plant with a closed fuel reprocessing cycle (mini-nuclear park). Subsequent operation has been as an irradiation facility, a role which will continue into the foreseeable future. Since the beginning of operation in 1961, operating experience of EBR-II has been very satisfactory. Most of the components and systems have performed well. In particular, the mechanical performance of heat-removal systems has been excellent. A review of the operating experience reveals that all the original design objectives have been successfully demonstrated. To date, no failures or incidents resulting in serious in-core or out-of-core consequences have occurred. No water-to-sodium leaks have been detected over the life of the plant. At the present time, the facility is operating very well and continuously except for short shutdowns required by maintenance, refueling, modification, and minor repair. A plant factor of 76.9% was achieved for the calendar year 1976

    The spectrum of singly ionized iron (Fe II) has been recorded using high-resolution Fourier transform (FT) and grating spectroscopy over the wavelength range 900 A to 5.5 {mu}m. The spectra were observed in high-current continuous and pulsed hollow cathode discharges using FT spectrometers at the Kitt Peak National Observatory, Tucson, AZ and Imperial College, London and with the 10.7 m Normal Incidence Spectrograph at the National Institute of Standards and Technology. Roughly 12,900 lines were classified using 1027 energy levels of Fe II that were optimized to measured wavenumbers. The wavenumber uncertainties of lines in the FT spectra range from 10{sup -4} cm{sup -1} for strong lines around 4 {mu}m to 0.05 cm{sup -1} for weaker lines around 1500 A. The wavelength uncertainty of lines in the grating spectra is 0.005 A. The ionization energy of (130,655.4 {+-} 0.4) cm{sup -1} was estimated from the 3d{sup 6}({sup 5}D)5g and 3d{sup 6}({sup 5}D)6h levels.

    The Brookhaven National Laboratory. Accelerator Test Facility (BNL ATF) is currently undergoing a major upgrade (ATF-II). Together with a new location and much improved facilities, the ATF will see an upgrade in its major capabilities: electron beam energy and quality and CO2 laser power. The electron beam energy will be increased in stages, first to 100-150 MeV followed by a further increase to 500 MeV. Combined with the planned increase in CO2 laser power (from 1-100 TW), the ATF-II will be a powerful tool for Advanced Accelerator research. A high-brightness electron beam, produced by a photocathode gun, will be accelerated and optionally delivered to multiple beamlines. Besides the energy range (up to a possible 500 MeV in the final stage) the electron beam can be tailored to each experiment with options such as: small transverse beam size (<10 um), short bunch length (<100 fsec) and, combined short and small bunch options. This report gives a detailed overview of the ATFII capabilities and beamlines configuration.

    The invariant chain (Ii) is the critical third chain required for the MHC class II heterodimer to be properly guided through the cell, loaded with peptide, and expressed on the surface of antigen presenting cells. Here, we report the isolation of the nurse shark Ii gene, and the comparative analysis of Ii splice variants, expression, genomic organization, predicted structure, and function throughout vertebrate evolution. Alternative splicing to yield Ii with and without the putative protease-protective, thyroglobulin-like domain is as ancient as the MHC-based adaptive immune system, as our analyses in shark and lizard further show conservation of this mechanism in all vertebrate classes except bony fish. Remarkable coordinate expression of Ii and class II was found in shark tissues. Conserved Ii residues and cathepsin L orthologs suggest their long co-evolution in the antigen presentation pathway, and genomic analyses suggest 450 million years of conserved Ii exon/intron structure. Other than an extended linker preceding the thyroglobulin-like domain in cartilaginous fish, the Ii gene and protein are predicted to have largely similar physiology from shark to man. Duplicated Ii genes found only in teleosts appear to have become sub-functionalized, as one form is predicted to play the same role as that mediated by Ii mRNA alternative splicing in all other vertebrate classes. No Ii homologs or potential ancestors of any of the functional Ii domains were found in the jawless fish or lower chordates. Copyright © 2011 Elsevier Ltd. All rights reserved.

  17. Chelation of Cu(II, Zn(II, and Fe(II by Tannin Constituents of Selected Edible Nuts

    2009-12-01

    Full Text Available The tannin fractions isolated from hazelnuts, walnuts and almonds were characterised by colorimetric assays and by an SE-HPLC technique. The complexation of Cu(II and Zn(II was determined by the reaction with tetramethylmurexide, whereas for Fe(II, ferrozine was employed. The walnut tannins exhibited a significantly weaker reaction with the vanillin/HCl reagent than hazelnut and almond tannins, but the protein precipitation capacity of the walnut fraction was high. The SE-HPLC chromatogram of the tannin fraction from hazelnuts revealed the presence of oligomers with higher molecular weights compared to that of almonds. Copper ions were most effectively chelated by the constituents of the tannin fractions of hazelnuts, walnuts and almonds. At a 0.2 mg/assay addition level, the walnut tannins complexed almost 100% Cu(II. The Fe(II complexation capacities of the tannin fractions of walnuts and hazelnuts were weaker in comparison to that of the almond tannin fraction, which at a 2.5 mg/assay addition level, bound Fe(II by ~90%. The capacity to chelate Zn(II was quite varied for the different nut tannin fractions: almond tannins bound as much as 84% Zn(II, whereas the value for walnut tannins was only 8.7%; and for hazelnut tannins, no Zn(II chelation took place at the levels tested.

    Five new tetrametallic supramolecules of the motif [{(TL)(2)M(dpp)}(2)Ru(BL)PtCl(2)](6+) and three new trimetallic light absorbers [{(TL)(2)M(dpp)}(2)Ru(BL)](6+) (TL = bpy = 2,2'-bipyridine or phen = 1,10-phenanthroline; M = Ru(II) or Os(II); BL = dpp = 2,3-bis(2-pyridyl)pyrazine, dpq = 2,3-bis(2-pyridyl)quinoxaline, or bpm = 2,2'-bipyrimidine) were synthesized and their redox, spectroscopic, and photophysical properties investigated. The tetrametallic complexes couple a Pt(II)-based reactive metal center to Ru and/or Os light absorbers through two different polyazine BL to provide structural diversity and interesting resultant properties. The redox potential of the M(II/III) couple is modulated by M variation, with the terminal Ru(II/III) occurring at 1.58-1.61 V and terminal Os(II/III) couples at 1.07-1.18 V versus Ag/AgCl. [{(TL)(2)M(dpp)}(2)Ru(BL)](PF(6))(6) display terminal M(dπ)-based highest occupied molecular orbitals (HOMOs) with the dpp(π*)-based lowest unoccupied molecular orbital (LUMO) energy relatively unaffected by the nature of BL. The coupling of Pt to the BL results in orbital inversion with localization of the LUMO on the remote BL in the tetrametallic complexes, providing a lowest energy charge separated (CS) state with an oxidized terminal Ru or Os and spatially separated reduced BL. The complexes [{(TL)(2)M(dpp)}(2)Ru(BL)](6+) and [{(TL)(2)M(dpp)}(2)Ru(BL)PtCl(2)](6+) efficiently absorb light throughout the UV and visible regions with intense metal-to-ligand charge transfer (MLCT) transitions in the visible at about 540 nm (M = Ru) and 560 nm (M = Os) (ε ≈ 33,000-42,000 M(-1) cm(-1)) and direct excitation to the spin-forbidden (3)MLCT excited state in the Os complexes about 720 nm. All the trimetallic and tetrametallic Ru-based supramolecular systems emit from the terminal Ru(dπ)→dpp(π*) (3)MLCT state, λ(max)(em) ≈ 750 nm. The tetrametallic systems display complex excited state dynamics with quenching of the (3)MLCT emission at

    Zwilsky, Klaus M.

    1978-09-01

    This plan describes a general program for the effective utilization of this resource by the fusion materials community. Because its flux is low relative to levels expected in commercial fusion reactors, the RINS-II is not expected to produce data of direct engineering significance (with some exceptions). Rather, it will be used chiefly to aid in the development of models of high energy neutron effects. Such models are needed in projecting engineering data obtained in high flux fission reactors to the fusion environment. Fission reactors, because of their relatively soft neutron spectra, cannot produce the high ratio of transmutations to displacements (except in an important special case) or the high energy recoil atoms appropriate to fusion reactors utilizing the D-T reaction.

    Thousands of drums of radioactive/hazardous/mixed waste are currently stored at DOE sites throughout US; they are stored in warehouse facilities on an interim basis, pending final disposition. Recent emphasis on anticipated decommissioning of facilities indicates that many more drums of waste will be generated, requiring additional storage. Federal and state regulations dictate that hazardous waste covered by RCRA be inspected periodically for container degradation and to verify inventories. All known DOE waste storage facilities are currently inspected manually. A system to perform robotic inspection of waste drums is under development by the SRTC Robotics Group of WSRC; it is called the Stored Waste Autonomous Mobile Inspector (SWAMI). The first version, SWAMI I, was developed by the Savannah River Technology Center (SRTC) as a proof of principle system for autonomous inspection of drums in a warehouse. SWAMI I was based on the Transitions Research Corporation (TRC) HelpMate mobile robot. TRC modified the Helpmate to navigate in aisles of drums. SRTC added subsystems to SWAMI I to determine its position in open areas, read bar code labels on the drums up to three levels high, capture images of the drums and perform a radiation survey of the floor in the aisles. The radiation survey was based on SRTC patented technology first implemented on the Semi-Intelligent Mobile Observing Navigator (SIMON). The radiation survey is not essential for the inspection of drums, but is an option that can increase the utility and effectiveness of SWAMI in warehouses with radioactive and/or mixed waste. All the sensors on SWAMI I were fixed on the vehicle. From the success of SWAMI I, a second version, SWAMI II, was developed; it will be evaluated at Fernald and tested with two other mobile robots. Intent is to transfer the technology developed for SWAMI I and II to industry so that it can supply additional units for purchase for drum inspection

    Evaluating the primary data from ARGE ELBE, LAU Halle/Saale and the Environmental Specimen Banking (Umweltprobenbank) as well from publications from the Czech Republic (CHMU) the concentrations of the following low volatile chlorinated hydrocarbons were established for surface water, sediment, breams and eels from the rivers Elbe, Schwarze Elster, Mulde and Saale partly from 1989 till 1999: DDT and its metabolites DDE and DDD, partly as 2,4'- and 4,4' isomers; HCH ({alpha}-, {beta}-, {gamma}- and {delta} isomers); chlorinated benzenes with 1-6 Cl atoms and octachlorostyrene. The data evaluated were drawn up into tables - comprehensive in a separate supplement, in short versions within the text - and consolidated into graphs. Aim of the paper was a cause-oriented monitoring. The by far most important emission sources, found from the distance and time profiles as well as from special assessments of the substance patterns, were chemical plants. (orig.) [German] Durch Auswertung von Primaerdaten der ARGE ELBE, des LAU Halle/Saale und der Umweltprobenbank sowie von Publikationen aus Tschechien (CHMU) wurden fuer Oberflaechenwasser, Sediment, Brassen/Bleien und Aale aus der Elbe, Schwarzen Elster, Mulde und Saale fuer die Jahre von z.T. 1989 bis 1999 die Konzentrationen der folgenden schwerfluechtigen Kohlenwasserstoffe (SCKW) ermittelt: DDT und seine Metabolite DDE und DDD, z.T. als 2,4'- und 4,4'-Isomere; HCH ({alpha}-, {beta}-, {gamma}- und {delta}-Isomere); chlorierte Benzole mit 1-6 Cl-Atomen und Octachlorstyrol. Die ausgewerteten Daten wurden zu Tabellen - ausfuehrlich in einem gesonderten Tabellenanhang und verkuerzt im Textteil - zusammengestellt sowie zu Grafiken verdichtet. Ziel der Arbeit war ein ursachenorientiertes Monitoring. Als mit Abstand wesentlichste Emissionsquellen konnten anhand von Streckenprofilen und Zeitrastern sowie durch spezielle Auswertungen der Stoffmusterverteilungen Chemibetriebe ermittelt werden.

    Major histocompatibility complex class II (MHC-II) molecules sample peptides from the extracellular space, allowing the immune system to detect the presence of foreign microbes from this compartment. To be able to predict the immune response to given pathogens, a number of methods have been...... developed to predict peptide-MHC binding. However, few methods other than the pioneering TEPITOPE/ProPred method have been developed for MHC-II. Despite recent progress in method development, the predictive performance for MHC-II remains significantly lower than what can be obtained for MHC-I. One reason...

    Complexes of Mg(II), Ca(II), Ba(II) and Sr(II) with paracetamol drug were synthesized and characterized by elemental analysis, conductivity, UV–Vis, IR, and 1H NMR spectroscopy and thermal analysis, as well as screened for antimicrobial activity. The IR spectral data suggested that the ligand behaves as paracetamol behaves as a neutral bidentate ligand coordinated to the metal ions via the lone pair of electrons of nitrogen and carbonyl-O atoms of the amide group. From the microanalytical dat...

    The health of the environment is worsening every day. Monitoring of potentially toxic elements and remediation of environmental pollution are necessary. Therefore, the research and development of simple, inexpensive, portable and effective sensors is important. Electrochemistry is a useful component of the field of environment monitoring. The present study focuses on evaluating and comparing three types of electrodes (PIGE, PIGE/MWCNT/HNO3 and PIGE/MWCNT/EDTA/HNO3) employed for the simultaneous electrochemical determination of four potentially toxic elements: Cd(II), Pb(II), Cu(II) and Hg(II). Cyclic voltammograms were measured in an acetate buffer. The LOD, LOQ, the standard and relative precisions of the method and a prediction intervals were calculated (according to the technical procedure DIN 32 645) for the three electrodes and for each measured element. The LOD for PIGE/CNT/HNO3 (the electrode with narrowest calculated prediction intervals) was 2.98 × 10(-7) mol L(-1) for Cd(II), 4.83 × 10(-7) mol L(-1) for Pb(II), 3.81 × 10(-7) mol L(-1) for Cu(II), 6.79 × 10(-7) mol L(-1) for Hg(II). One of the benefits of this study was the determination of the amount of Hg(II) in the mixture of other elements.

    For the design of cost-effective coastal defence a precise estimate is needed of the 1/10 000 per year storm surge. A more precise estimate requires more observations. Therefore, the three greatest storm surges that hit the northern part of the Holland Coast in the 18th century are reconstructed.

    Full Text Available For the design of cost-effective coastal defence a precise estimate is needed of the 1/10 000 per year storm surge. A more precise estimate requires more observations. Therefore, the three greatest storm surges that hit the northern part of the Holland Coast in the 18th century are reconstructed. The reconstructions are based on paintings, drawings, written records and shell deposits that have recently appeared. The storm-surge levels of these storms have been estimated using numerical modelling of the coastal processes. Here we show how these reconstructions can be used in combination with extreme value statistics to give a more confident estimate of low probability events.

    Objective: To investigate the clinical significance of changes of serum insulin-like growth factor II (IGF-II) levels in patients with chronic heart failure. Methods: Serum IGF-II levels were measured with RIA in 132 cases of chronic heart failure and 45 controls. Results: Serum IGF-II levels were significantly higher in patients with chronic heart failure than those in the controls (t=0.033, P<0.001). IGF-II levels were highest in grade IV CHF patients (vs grade II t=3.963, P<0.01; vs grade III, t=3.578, P<0.01). In the twelve patients died in hospital, the serum IGF-II levels were significantly higher than those patients recovered (t=7.141, P<0.01). Conclusion: Serum IGF-II levels were increased in CHF patients and were highest in the most severe cases. (authors)
