    Whilst policy makers have tended to adopt an 'information-deficit model' to bolster levels of flood-risk preparedness primarily though communication strategies promoting awareness, the assumed causal relation between awareness and preparedness is empirically weak. As such, there is a growing interest amongst scholars and policy makers alike to better understand why at-risk individuals are underprepared. In this vein, empirical studies, typically employing quantitative methods, have tended to focus on exploring the extent to which flood-risk preparedness levels vary depending not only on socio-demographic variables, but also (and increasingly so) the perceptual factors that influence flood risk preparedness. This study builds upon and extends this body of research by offering a more solution-focused approach that seeks to identify how pathways to flood-risk preparedness can be opened up. Specifically, through application of a qualitative methodology, we seek to explore how the factors that negatively influence flood-risk preparedness can be addressed to foster a shift towards greater levels of mitigation behaviour. In doing so, we focus our analysis on an urban community in Ireland that is identified as 'at risk' of flash flooding and is currently undergoing significant flood relief works. In this regard, the case study offers an interesting laboratory to explore how attitudes towards flood-risk preparedness at the individual level are being influenced within the context of a flood relief scheme that is only partially constructed. In order to redress the dearth of theoretically informed qualitative studies in this field, we draw on Protection Motivation Theory (PMT) to help guide our analysis and make sense of our results. Our findings demonstrate that flood-risk preparedness can be undermined by low levels of efficacy amongst individuals in terms of the preparedness measures available to them and their own personal capacity to implement them. We also elucidate that

  7. Improving flood risk mapping in Italy: the FloodRisk open-source software

    2017-04-01

    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

  8. 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

  9. Anthropogenic impact on flood-risk: a large-scale assessment for planning controlled inundation strategies along the River Po

    Science.gov (United States)

    Domeneghetti, Alessio; Castellarin, Attilio; Brath, Armando

    2013-04-01

    The European Flood Directive (2007/60/EC) has fostered the development of innovative and sustainable approaches and methodologies for flood-risk mitigation and management. Furthermore, concerning flood-risk mitigation, the increasing awareness of how the anthropogenic pressures (e.g. demographic and land-use dynamics, uncontrolled urban and industrial expansion on flood-prone area) could strongly increase potential flood damages and losses has triggered a paradigm shift from "defending the territory against flooding" (e.g. by means of levee system strengthening and heightening) to "living with floods" (e.g. promoting compatible land-uses or adopting controlled flooding strategies of areas located outside the main embankments). The assessment of how socio-economic dynamics may influence flood-risk represents a fundamental skill that should be considered for planning a sustainable industrial and urban development of flood-prone areas, reducing their vulnerability and therefore minimizing socio-economic and ecological losses due to large flood events. These aspects, which are of fundamental importance for Institutions and public bodies in charge of Flood Directive requirements, need to be considered through a holistic approach at river basin scale. This study focuses on the evaluation of large-scale flood-risk mitigation strategies for the middle-lower reach of River Po (~350km), the longest Italian river and the largest in terms of streamflow. Due to the social and economical importance of the Po River floodplain (almost 40% of the total national gross product results from this area), our study aims at investigating the potential of combining simplified vulnerability indices with a quasi-2D model for the definition of sustainable and robust flood-risk mitigation strategies. Referring to past (1954) and recent (2006) land-use data sets (e.g. CORINE) we propose simplified vulnerability indices for assessing potential flood-risk of industrial and urbanized flood prone

  15. 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

    Flood management is adopting a more risk-based approach, whereby flood risk is the product of the probability and consequences of flooding. Two-dimensional flood inundation modeling is a widely used tool to aid flood-risk management. The aim of this study is to develop a flood inundation model that uses historical flow data to produce flood-risk maps, which will help to identify flood protection measures in the rural areas of Sri Lanka. The LISFLOOD-FP model was developed at the basin scale using available historical data, and also through coupling with a hydrological modelling system, to map the inundation extent and depth. Results from the flood inundation model were evaluated using Synthetic Aperture Radar (SAR) images to assess product accuracy. The impacts of flooding on agriculture and livelihoods were analyzed to assess the flood risks. It was identified that most of the areas under paddy cultivation that were located near the middle and downstream part of the river basin are more susceptible to flood risks. This paper also proposes potential countermeasures for future natural disasters to prevent and mitigate possible damages.

  1. AUS98 - The 1998 version of the AUS modular neutronic code system

    Energy Technology Data Exchange (ETDEWEB)

    Robinson, G.S.; Harrington, B.V

    1998-07-01

    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 AUS publications are the inclusion of a cross-section library based on ENDF/B-VI, the addition of the MICBURN module for controlling whole reactor burnup calculations, and changes to the system as a consequence of moving from IBM main-frame computers to UNIX workstations This report gives details of all system aspects of AUS and all modules except the POW3D multi-dimensional diffusion module refs., tabs.

  3. Calculation of reactivity coefficients using AUS

    International Nuclear Information System (INIS)

    Harrington, B.V.

    1992-01-01

    The DIDO class High-Flux Australia Reactor (HIFAR) at the Australian Nuclear Science and Technology Organization (ANSTO) achieved initial criticality in 1958. For the first 10 yr of operation, fuel management and safety arguments were based on parameters measured during the commissioning period of the reactor augmented by additional measurements where these were thought necessary, chiefly as a consequence of changes in the type of reactor fuel element or disposition of irradiation rigs. In the early 1970s, development of the modular neutronics code AUS began, and in the intervening years, a transition from experimental to calculated data has occurred. This has been partly the result of the difficulty of gaining reactor time for experimental purposes but, perhaps more importantly, partly the result of the realization of the difficulty of obtaining adequate accuracy in measurements of space and energy-dependent data. Experience in using the code and extensive benchmark testing has led to great confidence in the correctness of calculations to the point where the reactor can be almost entirely operated and managed with the use of calculated data. This paper briefly describes the present status of the AUS code modules and specific problems that have been addressed with them

  4. 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.

    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?...

    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.

    Full Text Available This paper reports on the findings of a pilot study examining teacher perceptions of the efficacy of the Kids Hope Aus. program. Kids Hope Aus. is an early intervention and prevention program for children at risk of social and academic disengagement. The program emphasises the significance of developing a child’s social skills to build resilience and enhance the child’s social engagement and general academic achievement within the school setting. The intervention incorporates an adult/child-mentoring framework that serves to ameliorate the effects of specific risk factors that place children at greater risk of vulnerability. The evaluation involved 188 teachers drawn from rural and metropolitan districts in the State of Victoria, Australia, of children who participated in the Kids Hope Aus. program. The findings of the study provide preliminary data that identifies the Kids Hope Aus. program as a cogent intervention framework for fostering greater social inclusion and academic enhancement for young children that can be easily disseminated in regular school communities.  Keywords:  mentoring, at-risk children, Kids Hope Aus., early intervention and prevention.

    The development of descriptive and explanatory models of complex system like ecosystems requires a certain methodological procedure which has been generated during the last 30 years. Essentially it is related to mathematical modeling thought it is not only the application of mathematical approaches and tools. Also aspects of philosophy of science and epistemology with regard to 'reality' and 'truth' must be taken into account. Only in a constructive perspective it is acceptable that also 'soft' data are used for modeling. System models in this way are strategies for generating hypotheses. In this paper it is attempted to present this issue by using simple models. (orig.) [German] Die Entwicklung von Beschreibungs- und Erklaerungsmodellen komplexer realer Systeme, wie es beispielsweise Oekosysteme sind, erfordert ein bestimmtes methodisches Vorgehen, das in den letzten 30 Jahren aufgebaut wurde. Im Wesentlichen handelt es sich um die mathematisch-systemische Modellierung. Dabei muss beachtet werden, dass es sich nicht nur um die Anwendung bestimmter mathematischer Ansaetze und Techniken handelt, sondern dass auch wissenschaftstheoretische und erkenntnistheoretische Aspekte zum Thema 'Wirklichkeit' und 'Wahrheit' mitbedacht werden muessen. Nur unter einer konstruktivistischen Perspektive ist es ohne weiteres akzeptabel, auch 'weiche' Daten zur Modellierung zu nutzen. Systemmodelle sind daher eine Strategie zur Hypothesengenerierung. Anhand von einfachen Modellen wird versucht, diesen Bereich in Grundzuegen darzustellen. (orig.)

    The Bethesda System for Reporting Thyroid Cytopathology category of atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) includes fine-needle aspiration (FNA) specimens that cannot straightforwardly be classified as benign or malignant. To determine whether morphological subcategorization based on atypia qualifiers and molecular testing could improve malignancy risk stratification of AUS/FLUS patients, this study assessed the correlation between these qualifiers and the molecular alterations commonly harbored by thyroid neoplasms. A total of 162 AUS/FLUS cases were subcategorized by atypia qualifiers (Hürthle cell changes, architectural atypia, and cytologic atypia [CyA]) and were tested for BRAF, N-H-KRAS, RET/PTC, and paired box 8 (PAX8)/peroxisome proliferator activated receptor γ (PPARg) mutations. CyA was observed more frequently in mutation-positive AUS/FLUS (14 of 37 [37.84%]) than mutation-negative AUS/FLUS (20 of 125 [16.00%]; P < .0084), and it specifically harbored the BRAFV600E point mutation. Malignancy was confirmed in the available follow-up. Conversely, although RAS was the most frequent mutation identified in AUS/FLUS FNA specimens (26 of 37 cases [70.27%]; P < .0001), it was distributed across various AUS/FLUS subcategories and was not significantly associated with a specific atypia qualifier or malignant outcome according to the available follow-up. Rearrangements of both RET/PTC (n = 1) and PAX8/PPARg (n = 3) were rarely retrieved in the FNA samples. BRAF and RAS mutations are associated with different AUS/FLUS qualifiers and hence have different risks of malignancy. Consequently, a hybrid molecular and morphological subcategorization system could improve the malignancy risk stratification of thyroid FNA samples diagnosed as AUS/FLUS.

    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. A Multi-Layer Fusion-Based Facial Expression Recognition Approach with Optimal Weighted AUs

    Full Text Available Affective computing is an increasingly important outgrowth of Artificial Intelligence, which is intended to deal with rich and subjective human communication. In view of the complexity of affective expression, discriminative feature extraction and corresponding high-performance classifier selection are still a big challenge. Specific features/classifiers display different performance in different datasets. There has currently been no consensus in the literature that any expression feature or classifier is always good in all cases. Although the recently updated deep learning algorithm, which uses learning deep feature instead of manual construction, appears in the expression recognition research, the limitation of training samples is still an obstacle of practical application. In this paper, we aim to find an effective solution based on a fusion and association learning strategy with typical manual features and classifiers. Taking these typical features and classifiers in facial expression area as a basis, we fully analyse their fusion performance. Meanwhile, to emphasize the major attributions of affective computing, we select facial expression relative Action Units (AUs as basic components. In addition, we employ association rules to mine the relationships between AUs and facial expressions. Based on a comprehensive analysis from different perspectives, we propose a novel facial expression recognition approach that uses multiple features and multiple classifiers embedded into a stacking framework based on AUs. Extensive experiments on two public datasets show that our proposed multi-layer fusion system based on optimal AUs weighting has gained dramatic improvements on facial expression recognition in comparison to an individual feature/classifier and some state-of-the-art methods, including the recent deep learning based expression recognition one.

    Full Text Available 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.

    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.

    Highlights: • Experimental data on AuSe were obtained from T = (400 to 700) K. • Superionic conductor AgI was used as the solid electrolyte. • EMF accuracy was improved by advanced cell design. -- Abstract: The numerical values on the standard thermodynamic functions of AuSe were determined by the electromotive force (EMF) method in a solid-state galvanic cell with a superionic conductor AgI as the solid electrolyte. According to the experimental data on the EMF vs. temperature, the analytical equations for Gibbs free energy, enthalpy and entropy were obtained for the single stable polymorphic form of AuSe. The temperature-dependent relationships of Gibbs free energy of formation of AuSe and the standard thermodynamic functions of compounds within the temperature range (400 to 700) K were also evaluated. No α–β transformation was identified in the gold saturation and β-form is a metastable modification of AuSe

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.

  19. 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

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.

    Full Text Available Mit dem vorliegenden Sammelband Geschlechterverhältnisse – Naturverhältnisse wird nach dem innovativen Beitrag der feministischen Debatte für umweltsoziologisches Denken gefragt und nach Überschneidungen, Grenzen und Zwischenräumen zwischen „Geschlecht“ und „Natur“ gesucht. In ihm wird der lobenswerte Versuch unternommen, einen Zusammenhang zwischen Geschlechter- und Naturverhältnissen herzustellen „die in der Umweltsoziologie bislang stark vernachlässigte feministische Diskussion und Geschlechterforschung einzubeziehen und als genderbezogene Perspektive zu etablieren“. (S. 9 Das Buch enthält Beiträge von 15 Autorinnen, die unterschiedliche Natur- und Geschlechtsverhältnisse facettenreich, überwiegend kreativ und theoretisch anspruchsvoll betrachten. Das Buch enthält Zugänge aus der allgemeinen Soziologie, den Sprach- und Kulturwissenschaften, aus politik- und naturwissenschaftlichen Zusammenhängen. Den ausdrücklich formulierten Anspruch, von multi- zu einer inter-disziplinären Durchdringung zu gelangen, erfüllt es nur in Ansätzen (besonders mit der Einleitung und den theoretischen Problemexplikationen. Das zustande gekommene „Nach-, Zusammen- und Querdenken“ über Begriffe, Theorien und neuere Forschungsansätze (von Foucault über Butler bis zu Donna Haraway belegt die Notwendigkeit, die naturwissenschaftlichen Annahmen „immanent zu dekonstruieren“. Sehr aufschlussreich sind in diesem Zusammenhang die Beiträge von Irmgard Schultz, Elvira Scheich, aber auch von Mary Mellor und besonders von Paula-Irene Villa, die interessante und kreative Gedanken zur Klärung des Verhältnisses von Natur, Kultur und Geschlecht anbieten. Deutlich wurde, dass weiterhin ein kontroverses Ringen um angemessene konzeptionelle Fassungen von Geschlechts- und Naturverhältnissen und die Integration von Gender als zentraler analytischer Querschnitts-Kategorie nötig sind.

    Purpose: The determination of the arterial input function (AIF) is necessary for absolute quantification of the regional cerebral blood volume and blood flow using dynamic susceptibility contrast MRI. The suitability of different vessels (ICA-internal carotid artery, MCA-middle cerebral artery) for AIF determination was compared in this study. Methods: A standard 1.5 T MR system and a simultaneous dual FLASH sequence (TR/TE1/TE2/{alpha}=32/15/25/10 ) were used to follow a bolus of contrast agent. Slice I was chosen to cut the ICA perpendicularly. Slice II included the MCA. Seventeen data sets from ten subjects were evaluated. Results: The number of AIF-relevant pixels, the area under the AIF and the maximum concentration were all lower when the AIF was determined from the MCA compared to the ICA. Additionally, the mean transit time (MTT) and the time to maximum concentration (TTM) were longer in the MCA, complicating the computerized identification of AIF-relevant pixels. Data from one subject, who was examined five times, demonstrated that the intraindividual variance of the measured parameters was markedly lower than the interpersonal variance. Conclusions: It appears to be advantageous to measure the AIF in the ICA rather than the MCA. (orig.) [Deutsch] Ziel: Die Bestimmung der arteriellen Inputfunktion (AIF) ist notwendig fuer die absolute Quantifizierung haemodynamischer Parameter mit der dynamischen suszeptibilitaetsgewichteten Magnetresonanztomographie (DSC-MRT). Es wurde untersucht, ob sich die Arteria cerebri media (ACM) ebenso zur Bestimmung der AIF eignet wie die dem Standardverfahren zugrundeliegende Arteria carotis interna (ACI). Methoden: Es wurden ein Standard-1,5 T-MR-Tomograph und eine simultaneous dual FLASH Sequenz (TR/TE1/TE2/{alpha}=32 ms/15 ms/25 ms/10 ) verwendet, welche die simultane Akquisition von zwei Schichten ermoeglicht. Die Positionierung der zwei Bildgebungsschichten wurde so gewaehlt, dass die ACI senkrecht geschnitten wurde und

    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. In einem Werkstattbericht werden erste Ergebnisse vorgestellt. The Institute of the History of the German Jews (Institut für die Geschichte der deutschenJuden, IGdJ is currently conducting a

    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.)

    The utilization of waste heat has been practised in cement works for many years. However, the clinker cooler exhaust air is being used for the first time in India to generate steam for a seawater desalination plant. The plant installed at the Gujarat cement works of Larsen and Toubro contributes to the production of 2040 m{sup 3}/day of demineralized water from seawater. Hot exhaust air from the clinker cooler at about 270 C is cooled to about 170 C in a waste heat recovery steam generator (WHRSG). The plant has now been in operation for more than three years and contributes to the production of water in an area in which water is a precious commodity. The plant was installed in an existing cement works, so a number of factors, such as operation of the clinker cooler, configuration and installation of the equipment, machinery and gas ducts, had to be taken into account during the design of the waste heat boiler. State-of-the-art techniques, such as pinch point analysis, finite element analysis and computational fluid dynamics, were used in the design. (orig.)

Mittels Fallbeispielen zur religiösen Bildung am religiösen Markt (= religiöse Institutionen außerhalb des Schulraums wird in diesem Beitrag aufgezeigt, dass der islamische Religionsunterricht im Gegensatz zu den religiösen Institutionen keine Monopolkirche sein darf, in der vorwiegend eine Art Volksfrömmigkeit vermittelt wird. Opportunities and Challenges of Religious Education in Schools – A Muslim Perspective This contribution is based on the argument that the role of Islamic religious education at schools should be reconceived in relation to the growing presence of origin-oriented religious institutions in Europe. In addition to the origin-oriented religious institutions in Europe, this paper aims to present the importance of Islamic religious education from the perspective of contextualized Islam. Based on case studies for religious education in the religious market (outside the education area this paper shows that the Islamic religious education cannot offer Church`s monopoly and act like origin-oriented religious institutions to mediate popular piety.

  14. Die Energiebranche am Beginn der digitalen Transformation: aus Versorgern werden Utilities 4.0

    Science.gov (United States)

    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.

    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.

    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 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.) [Deutsch] Im Jahre 1996 wurden die beiden grossen Waermespeicher in Hamburg-Bramfeld mit einem Volumen von 4.750 m{sup 3} und in Friedrichshafen-Wiggenhausen mit 12.000 m{sup 3} aus Beton mit innenliegender Edelstahlauskleidung fertiggestellt. 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. Es werden die ersten Ergebnisse dieses Forschungsvorhabens mitgeteilt und Empfehlungen fuer die weitere Entwicklung von Waermespeichern aus Hochleistungsbeton gegeben. (orig.)

    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. Nachfolgend sollen insbesondere die Regelungen zur Unterstuetzung der Kreislaufwirtschaft, ausgewaehlte Stofffluesse und der Verbleib dieser Stoffe und Materialien und der

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.

    Full Text Available Franz Rosenzweig gilt als Existenzphilosoph, weil er das Thema des Todes ins Zentrum der Argumentation in seinem philosophisch-theologischen Hauptwerk Der Stern der Erlösung gestellt hat. Die Religion wird dort als der Ort verstanden, an dem der Tod nicht mehr wie im a-religiösen Leben aus dem Leben herausgedrängt werden muss. Wenn Religion Liebe ist, dann ist der Tod so Teil des Lebens wie er Teil der Liebe zwischen zwei Liebenden ist: als bejahter Bestandteil ihres gemeinsamen Lebens.

    The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) collaborative project is a program designed to deploy long period magnetotelluric (MT) stations across the Australian continent at a nominal resolution of 0.5x0.5° (approximately 50 by 50 km). The program brings together Federal and State government geological surveys with universities to acquire these MT data sites. The aim is to use these data to produce a 3D model of the conductivity of Australia to lithospheric depths. To date, the entire state of Victoria has been imaged, along with a large portion of South Australia, and smaller regions in Queensland and New South Wales. A pool of instruments are used for these data collection tranches, with standards for acquisition parameters, processing and modelling developed to ensure consistent data acquisition. We will provide an update on the program, including current deployments, plus an overview of data collected so far. Finally, we will discuss the future acquisition plans of the AusLAMP project.

    In this contribution, important procedures for testing of adhesive bondings are presented. The strain-shear test with thick joined parts represents the basic online test procedure. An optimized test procedure and an extended data evaluation are described. By application of the finite element method an identification procedure has been developed, in order to get adhesive bonding layer properties for modelling of complex components which cannot be determined by such basic procedures. The new tool for materials testing has been applied to a silicon sealing substance for joined parts made of steel and aluminium. (orig.)

    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.) [Deutsch] In der Bundesrepublik Deutschland beschaeftigt sich die Max Aicher Umwelttechnik GmbH in Hammerau seit Mitte der Achtzigerjahre mit der Niedertemperaturkonvertierung (Pyrolyse) von Klaerschlamm. Versuche im Labor- und im halbtechnischen Massstab fuehrten zur Realisierung einer betriebstechnischen Anlage mit den Komponenten Schlammtrocknung und Konvertierung. Ziel des Aicher-Schlamm-Recycling-Verfahrens ist die Umwandlung der organischen Schlammfraktion in stofflich und energetisch verwertbare Oele. Bei der Umwandlung entsteht fixer Kohlenstoff, der im festen Rueckstand (Konversionskoks) angereichert wird. Neben dem gewonnenen Oel ist auch der produzierte Koks verwertbar. Einsatzstoffe fuer das Verfahren sind neben Klaerschlamm aus der kommunalen Abwasserreinigung vor allem industrielle Schlaemme mit hohen organischen Anteilen z.B.

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.

    With a district heat-network supply of appr. 9.500 GWh in the year 1997, the district heat share of the total low temperature potential of Austria amounted to barely 10%. 85% of this falls to the 8 cities with more than 50.000 inhabitants, to include the capital, Vienna. Next to the favourable climatic conditions, also the small district heat share is involved in the cause of an almost disappearingly small cold production from district heat in Austria. Further reasons for the small share of the district cold through district heat are that a large part of the offices and administration buildings, but also hotels, were built during the time of the monarchy, which means the 2nd half of the 19th century. Aside from rather high ceilinged rooms, these objects also have comparatively small window surfaces and thick brick walls with large storage effect, so that cooling becomes only necessary for a few hours in the year or for special occasions. Also the hydraulically generated electricity of over 70% of the yearly quantity of Austria, may be named as a reason. At the time of the snow melting in Austria's mountains, there are days, even weeks, where hydraulic power generation exceeds the demand in Austria and the calorific power plants - even the CHP's run on low power - if at all. (orig.) [German] Mit einer Fernwaerme-Netzeinspeisung von ca. 9.500 GWh hat im Jahre 1997 der Fernwaermeanteil am gesamten Niedertemperaturpotential Oesterreichs nur knapp 10% betragen. Davon entfallen 85% auf die 8 Staedte mit mehr als 50.000 Einwohnern, einschliesslich der Bundeshauptstadt Wien. Neben den guenstigen klimatischen Bedingungen ist also auch der geringe Fernwaermeanteil an den Ursachen einer nahezu verschwindend kleinen Kaelteproduktion aus Fernwaerme in Oesterreich beteiligt. Weitere Gruende fuer den geringen Anteil der Fernkaelte durch Fernwaerme sind, dass ein Grossteil der Buero- und Verwaltungsgebaeude, aber auch der Hotels, noch aus der Zeit der Monarchie, und zwar

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.

    Fischer, Martin R.

    2013-11-01

    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

As the majority of patients without other malformations are asymptomatic, it is hard to estimate the prevalence of these anomalies. Our goal was to report a case of a 28-year-old patient, male, referred to thorax X-ray due to high fever state (39ºC, nonresponder to medication. The X-ray suggested azygos vein dilatation. The interview about cardiovascular symptoms revealed thoracic pain during both physical exercises and at rest, and occasional dyspnea during sleep related to the period of intensification of physical exercises. Computadorized tomography with and without contrast did not solve the case, what explain the request of an angiotomography, that showed absence of thoracic inferior vena cava.

    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

    In two auxiliary cooling circuits of large power plant Heilbronn the recirculated cooling water has been treated with ozone since 1995 in order to abate mucilage-forming microbiology and to minimize corrosion - especially to eliminate pitting corrosion. It could be shown that the application of ozone in cooling circuits also of power plants has a number of advantages. Compared to other alternatives, ozone is the most effective microbiocide without environmental-relevant effects. As in this case ozone has been generated from the atmospheric air and electricity, no requirements regarding transport and storage are to be met. The ozone generator can be installed at any place. (orig.) [Deutsch] In zwei Nebenkuehlkreislaeufen des Grosskraftwerks Heilbronn wird das Rueckkuehlwasser seit November 1995 mit Ozon zur Bekaempfung schleimbildender Mikrobiologie und zur Minimierung der Korrosion - insbesondere zur Eliminierung der Lochkorrosion - behandelt. Es konnte gezeigt werden, dass die Anwendung von Ozon in Kuehlkreislaeufen auch im Kraftwerk eine Reihe von Vorteilen mit sich bringt. Ozon ist im Vergleich zu anderen Alternativen das wirkungsvollste Mikrobiozid ohne umweltrelevante Folgeprodukte. Da hier das Ozon aus atmosphaerischer Luft und Elektrizitaet erzeugt wurde, entfaellt jede Transportanforderung und Lagerhaltung. Der Ozongenerator ist ueberall installierbar. (orig.)

    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.

    A process was developed to purify the wastewater of a flue gas purification process of a wood combustion plant. The water treatment process consists of a filtration with saw-dust and a reverse-osmosis process. A pilot plant has been developed and the performance has been tested. (SR) [Deutsch] Im Auftrag der Firma Wilhelm Mende GmbH, Gittelde/Harz, fuehrt das Institut fuer Siedlungswasserwirtschaft und Abfalltechnik der Universitaet Hannover im Fruehjahr 1996 am Waschwasser der dortigen Rauchgasreinigungsanlage eine Bestandsaufnahme durch, um die Ursachen fuer die Betriebsstoerungen herauszufinden. Bei den Untersuchungen wurde festgestellt, dass die Waschwasserreinigung nur unzureichend funktionierte und einige konzeptionelle Fehler aufwies. Aufbauend auf den Voruntersuchungen wurde ein kombiniertes Verfahren aus herkoemmlicher Filtration und einer Umkehrosmose entwickelt, mit dem es moeglich sein sollte, die Belastung des Waschwassers auf einem fuer die Systemstabilitaet ausreichenden Niveau zu halten. Das Konzept wurde in Pilotversuchen im Fruehherbst 1996 erfolgreich geprueft. Die grosstechnische Anlage wird derzeit von der Fa. Amafilter installiert und getestet. Betriebsergebnisse liegen z.Zt. noch nicht vor. Die wissenschaftliche Inbetriebnahmebegleitung erfolgt durch das Institut und wird von der Deutschen Bundesstiftung Umwelt gefoerdert. (orig.)

    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

    Sitting time questionnaires have largely been validated in small convenience samples. The validity of this multi-context sitting questionnaire against an accurate measure of sitting time is reported in a large demographically diverse sample allowing assessment of validity in varied demographic subgroups. A subgroup of participants of the third wave of the Australian Diabetes, Obesity, and Lifestyle (AusDiab3) study wore activPAL3™ monitors (7 days, 24 hours/day protocol) and reported their sitting time for work, travel, television viewing, leisure computer use and "other" purposes, on weekdays and weekend days (n = 700, age 36-89 years, 45% men). Correlations (Pearson's r; Spearman's ρ) of the self-report measures (the composite total, contextual measures and items) with monitor-assessed sitting time were assessed in the whole sample and separately in socio-demographic subgroups. Agreement was assessed using Bland-Altman plots. The composite total had a correlation with monitor-assessed sitting time of r = 0.46 (95% confidence interval [CI]: 0.40, 0.52); this correlation did not vary significantly between demographic subgroups (all >0.4). The contextual measure most strongly correlated with monitor-assessed sitting time was work (ρ = 0.25, 95 % CI: 0.17, 0.31), followed by television viewing (ρ = 0.16, 95 % CI: 0.09, 0.24). Agreement of the composite total with monitored sitting time was poor, with a positive bias (B = 0.53, SE 0.04, p < 0.001) and wide limits of agreement (±4.32 h). This multi-context questionnaire provides a total sitting time measure that ranks participants well for the purposes of assessing health associations but has limited accuracy relative to activPAL-assessed sitting time. Findings did not differ in demographic subgroups.

    Marginal flow and gap flow through a highly staggered cascade consisting of slightly convex profiles were investigated in two steps. Cascades without gap were investigated in the first step and cascades with gap in the second. In the first step, a slightly staggered cascade of identical geometry was used for comparison. In the second step, an external rotor cascade of 9C7/32,5C50 profiles with a division ratio t/l = 1.0 and a staggering angle of {lambda} = 50 was used. At a Reynolds number Re{sub j} = 3.5 x 10{sup 5} and gap widths of s/l = 0.0, 0.01 and 0.3, flows, wakes and pressure distributions were measured and diagrams made. The measurements were evaluated by mass averaging and with the aid of the pulse method. In addition to the averaged results of a standard investigation, the dissertation comprises extensive data on 3D flow near the blade ends and at the side wall as a function of blade angles and gap widths between blades and side wall. This was the first time that marginal flow and gap flow of strongly staggered cascades with slightly convex profiles were investigated in a cascade wind tunnel. The findings are therefore quite new and deviate strongly from the results of earlier investigations on strongly convex profiles. The findings were compared with the results of compressor investigations, and good agreement was found.

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.)

    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 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.)

    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.

    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.

In the course of 37 test series strain controlled fatigue curves to crack initiation and stress-strain-curves under monotonic and cyclic loading were determined. All experimental data, hysteresis loops and determined cyclic properties are available in a database. A correlation between the mechanical properties from tensile tests and the properties from strain controlled cyclic experiments seems to be possible.

    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.

    In the general population, excessive sedentary behaviour is associated with increased all-cause mortality. Few studies have examined this relationship in people with cardiovascular disease (CVD). Using a sample of people with CVD who were excluded from an analysis of the Australian Diabetes, Obesity and Lifestyle (AusDiab) study, we examined the relationship between sedentary behaviour and 13-year all-cause mortality. In the original AusDiab study, television viewing time was used as a marker of sedentary behaviour in 609 adults (≥45 years of age) with CVD. During 6,291 person-years of follow-up (median follow-up 13 years), there were 294 deaths (48% of sample). Using the time scale of attained age, the Cox proportional hazards model predicting all-cause mortality adjusted for sex, self-rated general health, leisure-time physical activity, smoking status, education, household income, body mass index, lipid levels, blood pressure, and diabetes mellitus was used. Compared with a TV viewing time of 4hours per day. Sedentary behaviour was associated with increased risk of all-cause mortality in people with CVD, independent of physical activity and other confounders. In addition to the promotion of regular physical activity, cardiac rehabilitation efforts which also focus on reducing sedentary behaviour may be beneficial. Copyright © 2016.

OBJETIVO: Analisar o comportamento da flexibilidade corporal - global, por articulação e por movimento - em mulheres adultas jovens nas diferentes fases do CM. MÉTODOS: Estudou-se uma amostra de 15 mulheres. O grupo experimental (GE foi constituído de alunas eumenorréicas, enquanto o grupo controle (GC incluía alunas em uso regular havia pelo menos um mês de anticoncepcional oral (AO.

CONCLUSÃO: Os dados obtidos não corroboram a impressão empírica de que a flexibilidade varia durante as fases do CM. Não se pode, contudo, afastar a hipótese de que a ausência de variações tenha ocorrido devido a alguma característica da amostra ou por limitações do Flexiteste em identificar mínimas varia

    Full Text Available O artigo propõe uma reflexão sobre o Cinema no Amazonas, apresentando aspectos da produção audiovisual desde o início do século XX à contemporaneidade, dando ênfase a produção de cineastas locais. Propomos a configuração de um “ecossistema comunicacional” a partir da relação entre contexto histórico, artistas, meio ambiente, políticas públicas, estéticas e ideologias. A abordagem teórico-metodológica parte da ideia de sociologia das ausências e emergências, de Boaventura de Sousa Santos, em diálogo com autores amazônicos, como João de Jesus Paes Loureiro, e de teóricos da cultura e do audiovisual. Além da pesquisa bibliográfica foi realizado um estudo de campo para mapear a situação do setor audiovisual regional. Percebe-se que, por diversos fatores ao longo da história, o cinema amazonense é um segmento que se mantém praticamente imperceptível ou ignorado, pois além de estar apartado do sistema industrial de produção, distribuição e exibição, ainda não conquistou o reconhecimento do público regional.   PALAVRAS-CHAVE: Ecossistemas comunicacionais; Sociologia das emergências; cinema no Amazonas; Imaginário.     ABSTRACT This paper proposes a reflection on the Cinema in the Amazon, presenting aspects of audiovisual production since the beginning of the twentieth century to the contemporary, emphasizing the production of local filmmakers.

    Using the example of primary energy consumption for methanol production from cellulose-rich biomass, it is shown that process chain analysis with mathematical modelling of the technical systems enables calculations of eco-inventories as a function of the relevant process parameters. Optimisation of process chains with regard to ecological indicators or cost necessitates mathematical modelling because of the many different parameters and parameter combinations involved. (orig) [Deutsch] Am Beispiel des Primaerenergieaufwands bei der Methanolgewinnung aus zellulosealtiger Biomasse wurde gezeigt, dass die Prozesskettenanalyse mit Abbildung der technischen Systeme in mathematischen Modellen die Berechnung von Oekoinventaren in Abhaengigkeit der relevanten Prozessparameter erlaubt. Die Optimierung von Prozessketten hinsichtlich oekologischer Indikatoren oder Kosten ist wegen der Vielzahl an unterschiedlichen Parametern und deren Kombinationsmoeglichkeiten nur mit Hilfe mathematischer Modelle moeglich.

    Full Text Available In der gegenwärtigen Flüchtlingskrise zeigt sich auf eklatante Weise das Informationsdefizit, das die gegenseitige mediale Wahrnehmung der europäischen und afrikanischen Länder bestimmt. Während in Deutschland und Europa Fluchtursachen und -motive zumeist junger afrikanischer Migranten falsch eingeschätzt und innerkontinentale Migrationsprozesse in Afrika nur marginal in europäischen Medien thematisiert werden, nehmen auch viele Menschen in afrikanischen Ländern nur Ausschnitte aus der Realität des Lebens in Deutschland bzw. Europa wahr. Hieran hat auch die mangelnde Medienberichterstattung in afrikanischen Ländern über Hintergründe und Folgen der Flüchtlingsbewegungen erheblichen Anteil. Der Werkstattbericht bietet auf Grundlage von zwei deutsch-afrikanischen Konferenzen, Literatursichtung und eigenen Studien eine Einschätzung der Berichterstattung auf beiden Kontinenten.

    2003-07-01

    Component current treatment is a comparatively new idea in sewage treatment, and there are some open questions. Using bibliographic searches, laboratory experiments, own and external investigations of current projects and simulations, the author attempts to answer the following questions: Can urine be used as a fertiliser? Is it practicable? What is its value as a fertiliser? Can it replace mineral fertilisers? Will there be hygiene problems? Do pharmaceutical residues in urine present a problem? How well can the residual sewage be treated, without the urine fraction? How should large volumes of urine be collected in densely populated areas? Can urine be concentrated without a significant loss of nutrients? What technologies should be used? How will separation of urine affect conventional sewage treatment in urban agglomerations? Are there advantages, e.g. in terms of relieving the groundwater burden or cost savings? (orig.) [German] Die Teilstrombehandlung in der Abwasserwirtschaft ist eine relativ neue Idee und neben offensichtlichen Vorteilen gibt es zahlreiche ungeklaerte Fragen. Anhand von Literaturrecherchen, Laborversuchen, eigenen und externen Untersuchungen an laufenden Projekten sowie Simulationen soll diese Arbeit einen Beitrag zur Beantwortung der folgenden Fragen leisten: - Ist die Duengung mit Gelbwasser praktikabel? Wie ist der Duengewert von Gelbwasser? Laesst sich damit Mineralduenger ersetzen? - Ist die Duengung mit Gelbwasser aus hygienischer Sicht problematisch? - Besteht bei der Nutzung von Gelbwasser als Duengemittel eine Gefaehrdung aufgrund von pharmazeutischen Rueckstaenden im Urin? - Wie gut laesst sich das restliche Abwasser ohne Gelbwasser reinigen? - Wie geht man in dicht besiedelten Gebieten mit grossen gesammelten Gelbwasservolumina um?

The electrostatic pre-separation of dust can reduce the dust loading of the catalyst significantly. An influence of the catalytic exhaust gas after-treatment on the dust composition based on the present investigations could not be clearly proven, but a dramatic impact, however, can be excluded from the studies. [German] Die verstaerkte Nutzung von fester Biomasse in Kleinfeuerungsanlagen zur Erzeugung von Waerme aus regenerativen Energiequellen geht leider mit einem erhoehten Ausstoss an luftgetragenen Schadstoffen einher. Die Minderung ist einerseits durch den Einsatz hochwertiger moderner Feuerungen nach dem neusten Stand der Technik moeglich. Andererseits werden derzeit mehrere vielversprechende Verfahrensansaetze zur Nachruestung von Kleinfeuerungen entwickelt, die eine effektive Emissionsminderung durch die nachtraegliche Behandlung des Abgases erlauben sollen. Die im Rahmen dieses Projektes erarbeitete Uebersicht der am Markt verfuegbaren oder in aktuellen Forschungsprojekten in der Entwicklung befindlichen sekundaeren Emissionsminderungstechniken an Biomasse-Kleinfeuerungsanlagen zeigt, dass weiterhin erheblicher Forschungsbedarf zur nachhaltigen Waermeerzeugung aus biogenen Festbrennstoffen besteht.

    Introduction: There are many problems in the radiological diagnosis of aseptic loosening in total hip arthroplasty. Computed tomography (CT) and magnetic resonance tomography (MRT) are not usable for metallic implants (stainless steel, cobalt alloy, titanium alloy). Material and Methods: From April 1993 to December 1993 15 CFRP non-cemented hip prostheses have been implanted. In a prospective clinical study plane radiographs, CT and MRT have been analysed. Results: Three stems were revised (1 femoral fracture, 1 severe thigh pain, 1 aseptic loosening). CFRP are not visible in plane radiographs. There was a complete (two-third of the cases) or nearly complete (one-third of the cases) small sclerotic interface between the prosthesis and the bone, these were apparent in CT and MRT in stable implant cases and did not have any clinical correlations. Discussion: The small sclerotic interface is quite different in comparison to so called `Reactive lines`. In one case of aseptic loosening there was an interposition of soft tissue between prothesis and bone in MRT and CT. CFRP inaugurates new diagnostic possibilities in aseptic loosening of hip prosthesis and in tumour surgery too. (orig.) [Deutsch] Einleitung: Die Diagnostik der aseptischen Endoprothesenlockerung bereitet mitunter im Routineroentgenbild erhebliche Probleme. Bei den zumeist verwendeten Implantaten (Material: rostfreier Stahl, Titan- oder Kobaltbasislegierungen) sind Magnetresonanztomographie (MRT) und Computertomographie (CT) wegen grenzschichtnaher Artefakte nicht einsetzbar.

    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.

    Emerging evidence suggests that psychosocial stress may influence weight gain. The relationship between stress and weight change and whether this was influenced by demographic and behavioral factors was explored. A total of 5,118 participants of AusDiab were prospectively followed from 2000 to 2005. The relationship between stress at baseline and BMI change was assessed using linear regression. Among those who maintained/gained weight, individuals with high levels of perceived stress at baseline experienced a 0.20 kg/m(2) (95% CI: 0.07-0.33) greater mean change in BMI compared with those with low stress. Additionally, individuals who experienced 2 or ≥3 stressful life events had a 0.13 kg/m(2) (0.00-0.26) and 0.26 kg/m(2) (0.14-0.38) greater increase in BMI compared with people with none. These relationships differed by age, smoking, and baseline BMI. Further, those with multiple sources of stressors were at the greatest risk of weight gain. Psychosocial stress, including both perceived stress and life events stress, was positively associated with weight gain but not weight loss. These associations varied by age, smoking, obesity, and multiple sources of stressors. Future treatment and interventions for overweight and obese people should consider the psychosocial factors that may influence weight gain. Copyright © 2013 The Obesity Society.

    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.) [Deutsch] In der vorliegenden Arbeit wird ein Konzept zur probabilistischen Sicherheitsanalyse des Fallrichtungsabbruchs turmartiger Bauwerke aus Stahlbeton entwickelt. Ausgehend von einem definierten Anforderungsprofil an den ordnungsgemaessen Ablauf eines Fallrichtungsabbruchs werden Modellvorstellungen herausgearbeitet, die einzelne Bauwerksgrenzzustaende abbilden, welche sich zur Beurteilung des Gesamtvorgangs eignen. Unsicherheiten in den Eingangsgroessen werden durch deren Auffassung als Wahrschlichkeitsdichten erfasst. Unsicherheiten in den Modellbildungen werden durch den jeweiligen Einsatz unterschaetzender und ueberschaetzender Betrachtungen, sogenannter Minoranten und Majoranten, beruecksichtigt. Anhand zweier Beispiele wird abschliessend demonstriert, wie die erhaltene operative Versagenswahrscheinlichkeit zur Objektivierung von Sicherheitsbetrachtungen herangezogen werden kann. Dabei beruht die numerische Umsetzung auf einer Monte-Carlo Simulation. (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.

    Several studies have suggested that dairy food may reduce the risk of obesity and metabolic abnormalities but few have been able to conclusively demonstrate that it reduces the risk of diabetes. The aim of the present analysis was to investigate if dairy food intake independently reduces the risk of diabetes. The Australian Diabetes Obesity and Lifestyle Study (AusDiab) is a national, population-based, prospective survey conducted over 5 years. Baseline measurements included a 121-item FFQ, anthropometrics and an oral glucose tolerance test. Forty-two randomly selected clusters across Australia. Adults aged ≥25 years who participated in the baseline survey and returned to follow-up 5 years later. A total of 5582 participants with complete data were eligible for analysis, 209 of whom had incident diabetes. Compared with men in the first tertile of dairy food intake, men in the third tertile had a significantly reduced risk of developing diabetes after adjustment for age, sex, total energy intake, family history of diabetes, education, physical activity, smoking status, fasting serum TAG and HDL cholesterol, systolic blood pressure, waist circumference and hip circumference (OR = 0·53, 95 % CI 0·29, 0·96; P = 0·033). A similar non-significant association was observed in women. Dietary patterns that incorporate high intakes of dairy food may reduce the risk of diabetes among men. Further investigation into the relationship between dairy food intake and diabetes needs to be undertaken to fully understand the potential mechanism of this observation.

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

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

    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.

O experimento foi conduzido no Centro Experimental da Palma, Pelotas, RS. Foram utilizadas quatro linhas quase-isogênicas: F6-SG e F6-SZ, no ano de 2000 e F7-SG e F7-SZ no ano 2001, com cinco repetições. O caráter "stay-green" permitiu maior deposição de reservas na semente na fase próxima do ponto de maturidade fisiológica. A duração do período de enchimento da semente esteve associada ao acúmulo de matéria seca na semente, promovendo um maior peso médio da semente. Assim, o progresso do caráter taxa de enchimento da semente poderá ser obtido por meio de seleções de plantas com maior peso médio da semente.

    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.

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)

    The article presents a comprehensive, comparative analysis of various national schemes existing or being negotiated in EC member states for (negotiated) third-party access to power distribution systems and use-of-system pricing for power transmission transactions in the deregulated EU internal market in electricity, in order to elaborate and discuss aspects of improvement of the current German TPA scheme adopted by the industrial associations involved. The countries referred to for reasons of comparison are England and Wales, Norway, Sweden and Finnland, as well as Austria, which adopted a concept tailored rather to Austrian conditions than to the framework defined by the EU Internal Market Directive. (orig./CB) [German] In Deutschland wurde die Binnenmarktrichtlinie fuer Elektrizitaet bereits fruehzeitig mit einer Energierechtsreform im April 1998 und einer Kartellrechtsreform zum Januar 1999 umgesetzt. Der Diskussionsstand zum Zeitpunkt des Abfassens dieses Beitrags liess darauf schliessen, dass mit der neuen Verbaendevereinbarung ein Schritt in Richtung hoeherer Netznutzungstransparenz gelingt, fundamentale Bedenken aber bestehen bleiben. Aus diesen Grund erscheint eine Analyse von Ineffizienzen im deutschen Netzzugangssystem sinnvoll. Um das deutsche System nicht an theoretischen Modellen sondern an den Massstaeben praktikabler (weitgehend effizienter) Netzzugangsregimes zu messen, wird ein Vergleich mit Laendern mit laengerer Liberalisierungserfahrung herangezogen (England und Wales, Norwegen, Schweden, Finnland). Die Perspektive wird ergaenzt um das oesterreichische Konzept, das sich eher defensiv an die Vorgaben der Binnenmarktrichtlinie fuer Elektrizitaet anlehnt. Ein institutioneller und oekonomischer Vergleich der ausgewaehlten Netzzugangs- und Regulierungssysteme zeigt, dass der ordnungsrechtliche Rahmen fuer die Stromuebertragung und -verteilung im Zuge der Liberalisierung in den einzelnen Laendern im Prinzip unabhaengig von der Versorgungsstruktur

    Heating systems which are equipped with high- efficiency boilers save energy because the energy content of the flue gases is utilized through flue gas condensation. Stainless steel is an important high-efficiency boiler material. The chromium and nickel concentrations of acid condensates from high- efficiency systems in waste water were analyzed. Stainless-steel samples were immersed in a model condensate over a period of 10 weeks. Fresh model condensates were prepared after one week and three weeks to measure metal dissolution as a function of time. The longer the samples were immersed the more did the nickel concentrations in the model concentrate decrease. Without exception, the concentrations were clearly below the maximum permissible values laid down in leaflet M 251 which is issued by Abwassertechnische Vereinigung e.V. The expected inadmissibly high nickel concentrations did not occur in the acid condensates. (orig.)

    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

    The development of ice covers on large rivers can result in ice jamming and extensive flooding. Decision makers require up-to-date information on river ice development to identify and mitigate potential hazards. Satellite based monitoring services offer an ideal method to collect information on river ice repeatedly and consistently throughout the ice season. Recently launched satellites, such RADARSAT-2, provide a number of improved capabilities, such as higher spatial resolution and multiple polarization modes, which could potentially enhance river ice monitoring services. A major motivation for this research was to improve the satellite-based river ice monitoring service currently delivered to a variety of end users under C-CORE’s Polar View initiative, by evaluating the potential of dual-polarized SAR data for improved river ice classification. A project was initiated to evaluate the utility of dual-pol (HH and HV) SAR data for river ice monitoring, and aims to develop a new river ice classification algorithm with test sites in Canada and Russia. EO data and field data were collected from 2005 to 2008, and were correlated by date and location to identify river ice training sites. Field data include annotated maps, aerial and field photographs, aerial video, ice observer reports and emails from end users in the field. Dual-pol SAR data combined with field data were used to develop a quadratic discriminant classifier algorithm based on image backscatter values and texture measures derived from the Grey Level Co-occurrence Matrix (GLCM). A sequential forward selection algorithm was employed to select the set of variables used in the classification algorithm. The results of this analysis indicate an improved separability of ice classes resulting from the incorporation of both the HV channel and GLCM texture measures. The differentiation of ice types was further improved by using a region-based approach, rather than pixel-based classification. Validation of the resulting dual-pol, region-based classification algorithm with ground-truth data showed an overall classification accuracy in excess of 90%. EO-based monitoring has significant potential to guide aerial and field reconnaissance missions to cover specific river sections instead of relying on a systematic coverage, which might miss critical developments. Likewise, EO-based observations can be gathered on days where flights or field visits are not possible (e.g. night-time), or acquired over expanded areas beyond typical flight paths or areas of field reconnaissance. The enhanced ability to track ice front progress and characterize critical ice types makes EO-based monitoring a powerful tool for decision makers concerned with mitigating ice-related flood risk. This work is supported by the Canadian Space Agency under the Earth Observation Application Development Program (EOADP). The data came from the European Space Agency, under the GMES project.

  10. Flood-risk mapping: contributions towards an enhanced assessment of extreme events and associated risks

    2006-01-01

    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.

  11. Eliciting knowledge on soft flood-risk management strategies in the Ukrainian Tisza river basin

    This paper focuses on a participatory knowledge elicitation process (KnETs) to explore decision-making criteria regarding ‘soft' techniques for flood risk management in the Ukrainian Tisza river basin. Communities in this region are faced with frequent floods and limited governmental budgets to cope with flood impacts. To identify the potential for soft flood protection measures as opposed to traditional technical solutions, we explored the decision-making heuristics of village council heads and the conditions under which they do or do not prepare for a flood event. Tacit knowledge, which is often unconscious and therefore difficult to describe, is complex to uncover through conventional interview techniques. To address this issue, a participatory process has been designed to reveal this knowledge without losing its connection to the context in which it is applied. That is, the KnETs process has been designed to understand context-relevant adaptive strategies and the reasons they are chosen in a natural resource management context. The process can be adapted to explore the contextual specificities of many situations ranging from flood and drought risk management to livelihood choices and the adaptation options considered in each set of circumstances. This interdisciplinary approach integrates ethnographic methods from the social sciences domain with classical computer science knowledge engineering techniques to address current bottlenecks (related to time and resource requirements) in both areas of research. This provides a participatory process, from knowledge elicitation to knowledge representation, verification and validation, providing a greater clarity of local data and thus possibly a greater understanding of social vulnerability and adaptive behaviour in flood situations.

    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

    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.

[German] Hydraulische in-situ Sanierungsverfahren erfahren derzeit im Rahmen der Altlastenbearbeitung eine zunehmende Bedeutung zur Beseitigung von Untergrundkontaminationen, vor allem in innerstaedtischen Bereichen.

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.

    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).

    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.

    Full Text Available Mit dem vorliegenden Sammelband Geschlechterverhältnisse – Naturverhältnisse wird nach dem innovativen Beitrag der feministischen Debatte für umweltsoziologisches Denken gefragt und nach Überschneidungen, Grenzen und Zwischenräumen zwischen „Geschlecht“ und „Natur“ gesucht. In ihm wird der lobenswerte Versuch unternommen, einen Zusammenhang zwischen Geschlechter- und Naturverhältnissen herzustellen „die in der Umweltsoziologie bislang stark vernachlässigte feministische Diskussion und Geschlechterforschung einzubeziehen und als genderbezogene Perspektive zu etablieren“. (S. 9 Das Buch enthält Beiträge von 15 Autorinnen, die unterschiedliche Natur- und Geschlechtsverhältnisse facettenreich, überwiegend kreativ und theoretisch anspruchsvoll betrachten. Das Buch enthält Zugänge aus der allgemeinen Soziologie, den Sprach- und Kulturwissenschaften, aus politik- und naturwissenschaftlichen Zusammenhängen. Den ausdrücklich formulierten Anspruch, von multi- zu einer inter-disziplinären Durchdringung zu gelangen, erfüllt es nur in Ansätzen (besonders mit der Einleitung und den theoretischen Problemexplikationen. Das zustande gekommene „Nach-, Zusammen- und Querdenken“ über Begriffe, Theorien und neuere Forschungsansätze (von Foucault über Butler bis zu Donna Haraway belegt die Notwendigkeit, die naturwissenschaftlichen Annahmen „immanent zu dekonstruieren“. Sehr aufschlussreich sind in diesem Zusammenhang die Beiträge von Irmgard Schultz, Elvira Scheich, aber auch von Mary Mellor und besonders von Paula-Irene Villa, die interessante und kreative Gedanken zur Klärung des Verhältnisses von Natur, Kultur und Geschlecht anbieten. Deutlich wurde, dass weiterhin ein kontroverses Ringen um angemessene konzeptionelle Fassungen von Geschlechts- und Naturverhältnissen und die Integration von Gender als zentraler analytischer Querschnitts-Kategorie nötig sind.

    Full Text Available ResumoA crescente exposição a estressores na vida cotidiana aumentou significativamente a investigação da resposta ao estresse nas duas últimas décadas. 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.

    Acute gastrointestinal bleeding in patients with liver cirrhosis is associated with a high mortality. Ileal varices and collaterals from ectopic vessels are extremely rare, encountered in less than 5% of the cirrhotic patients. The diagnosis is frequently delayed because the regular diagnostic methods such as gastroscopy or colonoscopy are unsuccessful in accurate the source of bleeding in the majority of the cases. We report an unusual case of massive and uncontrollable lower intestinal bleeding from ileal varices with right ovarian vein anastomosis in a 56 year-old female patient with liver cirrhosis and previous history of abdominal and pelvic surgery. The accurate angiographic and computed tomography diagnosis allowed fast decompression of the portal venous system using a transjugular intrahepatic portosystemic shunt. (orig.) [German] Akute gastrointestinale Blutungen sind bei Leberzirrhosepatienten mit einer hohen Mortalitaet verbunden. Ileale Varizen und Kollateralen aus anderen ektopen Gefaessen des Darms sind extrem selten und treten bei weniger als 5% aller Zirrhosepatienten auf. Die Diagnosestellung erfolgt oft verspaetet, da die ueblichen diagnostischen Untersuchungsmethoden wie Gastroskopie oder Koloskopie in den meisten Faellen die Blutungsquelle nicht ausreichend darstellen. Wir berichten ueber einen ungewoehnlichen Fall von massiver und unkontrollierbarer unterer gastroinstestinaler (GI-)Blutung aus ilealen Varizen mit Verbindung zur rechten V. ovarica einer 56-jaehrigen Frau, bei der anamnestisch eine Leberzirrhose und abdominelle Operationen sowie Operationen im Bereich des Beckens bekannt waren.

    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.). [Deutsch] Die Gehalte an molekularem Stickstoff (N{sub 2}) in Erdgaslagerstaetten des Nordwestdeutschen Beckens koennen Werte von nahezu 100 Vol.-% (Stickstoffprovinz) erreichen und stellen somit ein hohes Explorationsrisiko dar.

    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.)

    This study describes smart Cu(II)-aptamer complexes based gold nanoplatform for tumor micro-environment triggered programmable prodrug release, in demand photodynamic therapy and aggregation induced photothermal ablation of hepatocellular carcinoma. The nanoplatform is consist of monodispersed gold nanoparticle (GNP) that is binding to HCC cell specific targeting aptamers (TLS11a) through Au-S bond; the aptamer is labeled with Ce6 at the 5'end and coordinated with Cu(II) through (GA) 10 repeating bases to load AQ4N at the 3' end. In normal physiological conditions, the fluorescence and ROS generation ability of Ce6 are quenched by GNPs via RET; but in cancerous cells, the fluorescence and the ROS generation of Ce6 could be recovered by cleavage of Au-S bond through high level of intracellular GSH for real-time imaging and in demand PDT. Meanwhile, the prodrug AQ4N release could be triggered by acid-cleavage of coordination bonds, then accompanied by a release of Cu(II) that would induce the electrostatic aggregation of GNPs for photo-thermal ablation; furthermore, the significantly enhanced chemotherapy efficiency could be achieved by PDT produced hypoxia to convert AQ4N into AQ4. In summary, here described nanoplatform with tumor cell specific responsive properties and programmable PDT/PTT/chemotherapy functions, might be an interesting synergistic strategy for HCC treatment.

    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.

    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.

    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.

    thus play an important role in practice.p bKurzfassung:/b In der tibetischen Gesundheitslehre Sowa Rigpa wird Gesundheit und Wohlbefinden als Resultat einer Balance der drei Körperprinzipien rLung, Tripa und Beken angesehen. Das Verhältnis dieser drei Energien ist bei jedem Menschen individuell und bestimmt seinen Konstitutionstyp. Ist z. B. das bewegende Prinzip rLung (dt. Windenergie im Überschuss vorhanden, kommt es zu so genannten „Windstörungen“, häufig gekennzeichnet durch Beschwerden wie Nervosität, Reizbarkeit, schlechten Schlaf oder durch somatische Stressfolgen wie etwa Verdauungsprobleme. Das rLung-Prinzip wird auch durch zunehmendes Alter und hormonelle Umstellung erhöht, was wiederum zu den bekannten menopausalen Unruhezuständen führen kann. Die tibetische Sowa Rigpa setzt v. a. überlieferte Vielpflanzenrezepturen ein, um aus der Balance geratene Körperprinzipien wieder zurück ins konstitutionsgerechte Gleichgewicht zu bringen. Charakteristisch für solche Rezepturen sind ihre vielschichtigen Wirkebenen, die synergistischen Effekte und im Allgemeinen eine gute Verträglichkeit. Z. B. wird bei Windstörungen die Rezeptur Padma Nervotonin eingesetzt, die ein erhöhtes rLung- Prinzip beruhigt und somit hilft, die innere Ruhe und Gelassenheit wiederzuerlangen. Durch Stress und Kälte kann auch die Verdauungsfunktion beeinträchtigt werden, die gemäß tibetischer Anschauung von der Verdauungswärme Me drod abhängig ist. Diese ist außerdem auch für die Funktion anderer abdominaler Organe zuständig, daher kann ein Mangel neben Verdauungsbeschwerden wie vorzeitiges Sättigungsgefühl, Blähungen, Völlegefühl und Magendrücken auch zur so genannten „Kalte-Nieren“-Symptomatik führen, mit verminderter Sexualfunktion, wiederkehrenden Harnwegsinfektionen und Lumbalschmerzen.

    The Belle II experiment will record a similar quantity of data to LHC experiments and will acquire it at similar rates. This requires considerable computing, storage and network resources to handle not only data created by the experiment but also considerable amounts of simulated data. Consequently Belle II employs a distributed computing system to provide the resources coordinated by the the DIRAC interware. DIRAC is a general software framework that provides a unified interface among heterogeneous computing resources. In addition to the well proven DIRAC software stack, Belle II is developing its own extension called BelleDIRAC. BelleDIRAC provides a transparent user experience for the Belle II analysis framework (basf2) on various environments and gives access to file information managed by LFC and AMGA metadata catalog. By unifying DIRAC and BelleDIRAC functionalities, Belle II plans to operate an automated mass data processing framework named a “production system”. The Belle II production system enables large-scale raw data transfer from experimental site to raw data centers, followed by massive data processing, and smart data delivery to each remote site. The production system is also utilized for simulated data production and data analysis. Although development of the production system is still on-going, recently Belle II has prepared prototype version and evaluated it with a large scale simulated data production. In this presentation we will report the evaluation of the prototype system and future development plans.

  13. Evolved H II regions

    1975-01-01

    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

  14. Preliminary PBFA II design

    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

    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.

    2014-01-01

    Type II topoisomerases are essential enzymes that modulate DNA under- and overwinding, knotting, and tangling. Beyond their critical physiological functions, these enzymes are the targets for some of the most widely prescribed anticancer drugs (topoisomerase II poisons) in clinical use. Topoisomerase II poisons kill cells by increasing levels of covalent enzyme-cleaved DNA complexes that are normal reaction intermediates. Drugs such as etoposide, doxorubicin, and mitoxantrone are frontline therapies for a variety of solid tumors and hematological malignancies. Unfortunately, their use is also associated with the development of specific leukemias. Regimens that include etoposide or doxorubicin are linked to the occurrence of acute myeloid leukemias that feature rearrangements at chromosomal band 11q23. Similar rearrangements are seen in infant leukemias and are associated with gestational diets that are high in naturally occurring topoisomerase II–active compounds. Finally, regimens that include mitoxantrone and epirubicin are linked to acute promyelocytic leukemias that feature t(15;17) rearrangements. The first part of this article will focus on type II topoisomerases and describe the mechanism of enzyme and drug action. The second part will discuss how topoisomerase II poisons trigger chromosomal breaks that lead to leukemia and potential approaches for dissociating the actions of drugs from their leukemogenic potential.

    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?

    Full Text Available Não se pode compreender a eclesiologia do Vaticano II sem conhecer a vida, o estilo pastoral e o carisma de João XXIII, que convocou o Concílio e abriu o caminho em direção a uma nova configuração eclesial que acabava com séculos de uma Igreja de Cristandade. 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 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.

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

    Energy Technology Data Exchange (ETDEWEB)

    Hueggenberg, Daniel

    2015-11-06

    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

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

    Stalheim, O. H. V. (University of Wisconsin, Madison), and J. B. Wilson. Cultivation of leptospirae. II. Growth and lysis in synthetic medium. J. Bacteriol. 88:55–59. 1964.—Differences were found in the ability of leptospirae to grow in a synthetic medium; 43 strains, consisting of 16 serotypes, were tested and designated as either type I or type II. Type I leptospirae did not grow; type II grew and could be subcultured. The lytic effect of several lipids was measured with Leptospira pomona and L. canicola as representatives of type I and II leptospirae, respectively. L. pomona organisms were rapidly lysed by the monoolein of the synthetic medium and by other lipids as well; L. canicola cells were consistently more resistant. Although both organisms incorporated similar amounts of label when incubated in the presence of oleic-1-C14 acid, only L. canicola grew in a modified, nonlytic synthetic medium. No differences were found in susceptibility to lysis between virulent and avirulent L. canicola organisms. Mutant type I leptospirae grown in synthetic medium had increased resistance to lysis by surface-active agents; they were poorly agglutinated by antiserum. The role of protein in the growth and antigenicity of type I leptospirae is discussed. PMID:14197906

    Full Text Available Foi comparada a potência anticonvulsivamente do nitrazepam, do diazepam e da trimetadiona em 5 pacientes com ausências mioclônicas. Os doentes receberam, além das medicações anticonculsivantes, um placebo. O teste terapêutico foi constituído por tratamentos sucessivos de 4 dias, planejados com o fim de se eliminar os possíveis efeitos residuais de uma droga sobre a outra, administrada ulteriormente. Na análise dos resultados, a comparação das médias individuais dos diversos tratamentos foi baseada no teste de Tukey. Em dois casos não houve necessidade de análise estatística para demonstrar a superioridade do nitrazepam e do diazepam sobre os demais produtos utilizados; em outros dois, a aplicação do teste de Tukey levou à mesma conclusão. No quinto caso as flutuações do número de ausências mioclônicas durante o ensaio terapêutico sugerem comportamento semelhante, embora a análise estatística individual não revele diferenças significativas. Há indícios de que o nitrazepam tem ação superior ao diazepam sobre esse tipo de crise convulsiva. A trimetadiona revelou-se superior ao placebo, porém inferior ao nitrazepam e ao diazepam. O principal inconveniente do nitrazepam e do diazepam é o de precipitar crises generalizadas tônico-clônicas.The anticonvulsant potency of nitrazepan, diazepan and trimetadiones in five patients with myoclonic absences was compared. A placebo was also used. Therapeutic tests were performed by 4-days successive treatments designed to avoid the residual effects of one drug upon the other administered afterwards. In two cases statistical analysis was not necessary for demonstration of the superiority of nitrazepan and diazepan in regard to trimetadiones; in two others the application of Tukey's test allowed this same conclusion. In the last case the numeric variations of the seizures during the therapeutic essay suggest identical conclusion allthough the statistical analysis was not

OBJETIVO: Analisar o estado de pacientes em terapias específicas de HAP durante um ano de observação, em termos de QVRS, e investigar se possíveis associações entre a capacidade de exercício (CE e a QVRS persistem no médio prazo. MÉTODOS: Trinta e quatro pacientes em terapias para a HAP (bosentan e/ou sildenafil foram selecionados (idade de 14 a 58 anos, mediana de 35,5 anos, classe funcional II ou III, e avaliados no momento basal, e 3, 6, 9 e 12 meses depois, usando o teste de caminhada de 6 minutos e questionário SF-36 de QVRS. RESULTADOS: A distância percorrida nos seis minutos não mudou durante o acompanhamento (387 - 432 metros, valores da mediana, p=0.2775, o mesmo para a classe funcional e saturação periférica de oxigênio. Os escores SF-36 também se mantiveram estáveis, com a saúde física sempre pior que a saúde mental. Das 40 possíveis associações entre a CE e QVRS, apenas 12 foram significativas (30%, p90%, mas sensível em <43%. CONCLUSÃO: Os pacientes com HAP que se mantêm estáveis em termos da CE também parecem fazê-lo em termos de QVRS. Contudo, CE e QVRS não têm ligação consistente com o tempo, e devem ser analisadas como diferentes perspectivas no paciente individual.

    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

    The production of highly-purified demineralised water as feedwater for boilers with values of <0.2 {mu}S/cm conductivity and <200 ppb TOC is essential for the quality of steam within the steamwater cycle. Especially for the combined mode of operation with additional dosing of oxygen it is necessary not only to stay within these values but to remain below the requirements. Nowadays it is no problem to produce demineralized water with corresponding low conductivity. The sufficient reduction of TOC has become the main problem. The Rostock Power Plant, in co-operation with Steag encotec GmbH, Essen, and the University Hamburg Harburg, developed a new treatment and tested it for more than two years with accompanying analysis. (orig.) [German] Um die VGB-Richtwerte fuer das Kesselspeisewasser im Kraftwerk Rostock zu erreichen, wurde eine Vollentsalzungsanlage einschliesslich Vorreinigungsstufe errichtet. Sie bestand aus nur einem Aktivkohlefilter zur Adsorption der im Trinkwasser enthaltenen geloesten organischen Substanzen. Hohe Aluminiumgehalte im Trinkwasser fuehrten bald zu einer Blockierung der Aktivkohle, wodurch die Adsorbtion der Organika an der Aktivkohle erheblich gestoert wurde. Daraufhin erfolgte die Nachruestung eines zweiten Adsorberfilters, der vor den Aktivkohlefilter geschaltet wurde. Die erhoffte Reduzierung der Organika durch die neu errichtete zweistufige Ozonierung trat jedoch nicht ein. Im Gegenteil, die teilweise nur angespaltenen Organika wurden vom Adsorberharz der Vorreinigung teilweise irreversibel adsorbiert. Ueber Abhilfemassnahmen wird berichtet. (orig.)

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.

Im Beitrag wird partizipative Aktionsforschung als Methode zur Gestaltung von Theorie-Praxis-Korrelationen untersucht. Dazu wird zunächst das Theorie-Praxis-Problem als Relation der Korrelationen zwischen Theorie und Praxis in Forschungs- und Unterrichtsmethoden bestimmt. Anschließend wird durch Interpretationen von Theorien zur partizipativen Aktionsforschung und von Daten aus einem Projekt untersucht, ob die Relation von Forschung und Unterricht so gestaltet werden kann, dass zu souveränen Akten in solidarisch-libertären Gemeinschaften aufgefordert wird. Die Ergebnisse zeigen, dass dies möglich und die Methode also medienpädagogisch relevant ist. As for any education, the theory-practice transformation problem is relevant for media education. In this paper, participatory action research is investigated as a method to design the correlation of theory and practice. To do so, the theory-practice problem is understood as the relation of the correlations between theory and practice in research and teaching methods. Subsequently, it is researched if the relation of research and teaching can be designed to call for sovereign acts in solidary-libertarian communities. The research is conducted by interpreting participatory action research theories and project data. It is shown that it is possible to call for sovereign acts. Thus the suggested method can be considered as relevant for media education.

    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

    The present conception of LAMPF II is a high-intensity 16-GeV synchrotron injected by the LAMPF 800-MeV H/sup -/ 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.

    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.

  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

    2018-01-01

    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 suffers 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 ≥2Å are more reddened, showing colour excess E(B - V) ˜ 0.02, with respect to the systems with R <0.5 and most likely traces 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.

    Full Text Available The 5-chloro-2-methoxybenzoates of Mn(II, Co(II, Ni(II, Cu(II and Zn(II were synthesized as solids and their magnetic, spectral and thermal properties studied. The complexes possess colours typical of the M(II ions. The thermal stabilities were examined in air and nitrogen atmospheres and the products of decompositions were also identified. The magnetic susceptibilities of the complexes were measured over the temperature range 4.4–300 K and the magnetic moments were calculated. The results show that the 5-chloro-2-methoxybenzoates of Mn(II, Co(II and Ni(II are octahedral, high-spin complexes.

    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

    During the 1986-1993 period, a total of 392 persons, 185 of them being of German, 204 of CIS and one of Polish ntionality, were examined in connexion with the Chernobyl reactor accident. These examinations under aspects of radiation medicine were performed by the Clinical-diagnostic Branch of the Bundesgesundheitsamt (BGA; Federal Health Office) jointly with the Federal Office for Radiation Protection. The experience gained by some of the authors during their participation in national and international investigation activities at the site of the accident could be included in these studies. The programme of investigation included: - Medical examinations (including sonographies of the thyroid); - Laboratory analyses (including blood counts, thyroid hormone determinations, chromosomal analyses); - Activity measurements in a whole-body counter; In none of the cases, radiation-induced damage to health could be confirmed. The non-specific clinical findings, particularly in children, were primarily: Dental status requiring treatment; chronic rhinopharyngitis with general susceptibility to infection; swelling of lymph nodes of the head and neck; inflammation of the urinary tract and non-specific functional gastric disorder. Whole-body counting did no reveal an essential incorporation of caesium.

    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)

  1. Analyse interreligiöser Begegnung in der Praxis. Kontext, Bedingungen, Strategien und Konsequenzen am Beispiel lebensgeschichtlicher Erzählungen aus einem christlich-muslimischen Begegnungszentrum in Deutschland

    Full Text Available Interreligiöse Dialoge im Allgemeinen und christlich-muslimische Dialoge in Deutschland im Besonderen können einen wichtigen Beitrag zum friedlichen Zusammenleben leisten. Gleichzeitig stellen interreligiöse Dialoge einen Ort potenzieller interreligiöser Konflikte dar, was u.a. mit der Beschaffenheit von "Religion" zusammenhängt. Vor dem Hintergrund der gesellschaftlichen Relevanz potenzieller interreligiöser Konflikte und dem (präventiven Umgang damit in konkreten Begegnungssituationen ist das Thema für empirische Untersuchungen von besonderem Interesse. Die hier vorgestellte qualitative Studie hatte daher zum Ziel, einen Zugang zur Alltagspraxis interreligiöser Dialoge zu erlangen und diese Praxis zu analysieren. Mit der anfangs offen gehaltenen Forschungsfrage sollte herausgefunden werden, wie sich interreligiöser Austausch auf persönlicher Ebene gestaltet, wie die Beteiligten diesen wahrnehmen, wie sie in Begegnungssituationen handeln, und welche Überzeugungen sie dabei leiten. Zur Datenerhebung wurden die teilnehmende Beobachtung und narrative Interviews eingesetzt. Das Vorgehen bei der Auswertung leitete sich aus der relationalen Hermeneutik ab, ergänzt durch Kodierverfahren der Grounded-Theory-Methodologie. Die Ergebnisse umfassen den Versuch eines Modells interreligiöser Begegnung. In allen hierzu entwickelten Kategorien lassen sich Bezüge zum Thema "Lernen" herstellen, welches sich als interreligiöses Lernen interpretieren lässt. Daraus kann die begründete Vermutung abgeleitet werden, dass die Befähigung zum interreligiösen Austausch in der Praxis auch erst durch konkrete interreligiöse Begegnungen entstehen kann.

    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.

    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 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)

  10. Effect of Cu(II), Cd(II) and Zn(II) on Pb(II) biosorption by algae Gelidium-derived materials.

    2008-06-15

    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.

    2014-07-01

    Full Text Available A new phosphonate modified silica (PMS has been investigated for adsorption of Co(II, Ni(II, Cu(II, and Zn(II in aqueous solution. The adsorbent was modified of silica by immobilizing aminoethyl dihydrogen phosphate (AEPH2 on 1,4-dibromobutane grafted silica. The physicochemical of the adsorbent was investigated using Fourier Transform Infra-red (FTIR spectroscopy, X-ray Fluorescence (XRF, and N2 gas adsorption/desorption. The adsorption study was carried out in a batch system by mixing solution of metal ions at various pHs, contact times, and initial metal ion concentrations. The unadsorbed metals were determined by Flame Atomic Absorption Spectrophotometry (FAAS. Result of characterization showed that PMS has been successfully prepared. The product contained 45.99% (w/w silica and 1.33% (w/w phosphorous with surface area, pore volume, and pore size of 115.3 m2g-1; 0.7578 mLg-1; and 131.44 Å, respectively. Adsorption of metal ions on PMS occurred quite fast, less than 30 min. Modification of phosphonate on silica increased the adsorption capability, up to 8 times higher than that of unmodified silica, depending on metal ion type and pH solution. The capacity order of the metals adsorption was Cu(II>Co(II>Ni(II>Zn(II. Based on the adsorption characteristic, the adsorbent is promising to be applied as a material for solid phase extraction of transition metal ions.

    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.

  16. Dark matter detection - II

    2015-01-01

    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.

    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.This paper is an introduction to Cristopher Boorse's work. Boorse is a philosopher of medicine who created, in the 70s, the Bioestatistical Theory (BST. In this paper, we look into the structure of BST and its arguments, focusing on its epistemological basis as well as its logical and theoretical reasons for defining health as the absence of disease. After that, we discuss the critics addressed to Boorse throughout these twenty years of theorization by analyzing their actuality and adequacy. We also identify problems and strong points in the BST, bringing up not only the critics to the BST but Boorse's answers as well. Finally, we add some questions that can provide continuity and enrichment to the debate on the concept of health with the aim of exploring its applicability in a general health-disease-care approach, which is extremely necessary

    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. Andererseits haben die Windkraftanlagen direkt an den Aufstellungsorten negative Auswirkungen auf die Umwelt, wie zum Beispiel Stoerung der Voegel in Nahrungs- und Bruthabitaten, Vogelschlag oder Beeintraechtigung des Landschaftsbildes. Um moegliche Konflikte weitgehend zu vermeiden und die Akzeptanz fuer Windkraftanlagen zu erhoehen, wurde fuer den Kreis Soest ein Rahmenkonzept erarbeitet, in dem Gunst-, Restriktions

    The two major hereditary breast cancer susceptibility genes, BRCA1 and BRCA2 are associated with 85 to 90% of all hereditary breast and ovarian cancers. They encode for two proteins who participate in a common DNA damage response pathway associated with the double-strand break repair. The standard of gene analysis is complete gene sequencing, although this is a very expensive and time-consuming method. Therefore, it is necessary to select families with a high a-priori risk for having a mutation. Interpretation of gene testing results may be difficult as penetrance is not hundred percent and due to unclassified variants. Prevention of breast and ovarian cancer is possible with prophylactic surgery. Alternatively, endocrine prevention or intensified surveillance could be tried. The evidence of BRCA1 and BRCA2 concerning radiosensitivity is not clear yet. The susceptibility to radiation-induced DNA damage could have implications for therapy options. As the benefits of so far used diagnostic or therapeutic tools are high, they outweigh the possible risks due to increased radiosensitivity. (orig.) [German] Keimbahnmutationen in den BRCA1- und BRCA2-Genen machen 85 bis 90% aller hereditaeren Mamma- und Ovarialkarzinome aus. Die entsprechenden Proteine sind gemeinsam fuer Reparaturmechanismen im Zellzyklus, insbesondere auf der Doppelstrangebene verantwortlich. Als Standard zur genetischen Analyse gilt derzeit die Komplettsequenzierung der Gene, die jedoch aufgrund der Groesse der beiden Gene und der ausgepraegten Variabilitaet der Mutationen ein sehr aufwendiges und damit teures Verfahren darstellt. Eine Selektionierung von Familien mit hohem Risiko fuer eine Mutation, z.B. anhand der Familienanamnese, der beteiligten Tumorentitaeten oder aufgrund von histopathologischen Kriterien ist daher derzeit unerlaesslich. Die Interpretation der Ergebnisse der Gentestung kann aufgrund der unvollstaendigen Penetranz der Genmerkmale sowie des Problems der unklassifizierbaren

    Full Text Available Os erros na medicação podem acarretar sérias conseqüências aos pacientes, profissionais e instituições de saúde. Estes resultam de múltiplas causas, dentre elas a ilegibilidade e falta de informações das prescrições. Realizou-se um estudo de prescrições médicas com o objetivo de analisar a freqüência de riscos relacionados a erros de medicação. O estudo teve caráter quantitativo, do tipo descritivo e transversal, realizado nos meses de maio a julho de 2004. Analisaram-se 167 prescrições das clínicas médica, pediátrica e obstétrica do Hospital Nossa Senhora da Conceição (Fortaleza-CE. Cada prescrição foi retrospectivamente avaliada por um acadêmico de farmácia e por um farmacêutico. A legibilidade da prescrição foi classificada em: legível, pouco legível e ilegível. Verificouse também a ausência de informações referentes ao paciente, ao prescritor e aos medicamentos prescritos bem como o uso de abreviaturas e a denominação utilizada para o medicamento (genérico ou comercial. 78 (46,7% prescrições foram consideradas pouco legíveis ou ilegíveis. As principais informações ausentes nos itens contendo medicamentos (n=808 foram: forma farmacêutica (84,0% e concentração (61,5% e as abreviaturas foram mais utilizadas na via de administração (37,2% e posologia (35,3%. A denominação genérica esteve presente em 63,4% das prescrições. A identificação do prescritor estava ilegível em 147 (88,0% prescrições. Os dados sugerem que se faz necessário instituir, junto aos prescritores, medidas que reforcem o benefício de uma prescrição completa e correta e que, através da melhoria organizacional, tecnológica e educacional, o risco de erro de medicação para o paciente pode ser reduzido.

    Full Text Available

    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.

  5. Angiotensin II and taste sensitivity

    Full Text Available The sense of taste plays a major role in evaluating the quality of food components in the oral cavity. Sweet, salty, umami, sour and bitter taste are generally accepted as five basic taste qualities. Among them, salty taste is attractive to animals and influences sodium intake. Angiotensin II (ANG II and aldosterone (ALDO, which is stimulated by ANG II are key hormones that regulate sodium homeostasis and water balance. At the peripheral gustatory organs, it has been reported that ALDO increases the amiloride-sensitivity of the rat gustatory neural responses to NaCl in a time course of several hours. A recent study demonstrated that ANG II suppresses amiloride-sensitivity of the mouse gustatory and behavioral responses to NaCl via its receptor AT1 within an hour. Moreover, ANG II enhances sweet taste sensitivity without affecting umami, sour and bitter tastes. These results suggest that the reciprocal and sequential regulatory mechanisms by ANG II (as an acute suppressor together with ALDO (as a slow enhancer on the salt taste sensitivity may exist in peripheral taste organs, contribute to salt intake, and play an important role in sodium homeostasis. Furthermore, the linkage between salty and sweet taste modulations via the ANG II signaling may optimize sodium and calorie intakes.

    At the beginning of the year, both Units were connected to the grid and operating stably at 100% power. During 2004, 16,351 million kWh were generated, which is the highest gross annual production ever achieved in Almaraz NPP. Between the two units the year's accumulated unit capability factor was greater than 95.5% (99.89%in Unit I and 91.48% in Unit II). The operating factor was 100% in Unit I and 92.01% in Unit II. As the operating factor indicates, Unit I remained online without interruption throughout the entire year and operated stably from the beginning of its seventeenth operating cycle (october 27, 2003). Unit I generated a total of 8,522 million kWh, which is the highest ever per-unit annual gross production in Almaraz NPP. Unit II generated a total of 7,830 million kWh, it had a planned shutdown in January to replace one of the main transformers (phase S), and the fifteenth refueling outage took place in October. The gross electric energy accumulated at source is 155.957 million kWh in Unit I and 150,937 million kWh in Unit II. At year end both Units were operating at 100% power, with Unit I supplying 980 MWe and Unit II 985 MWe II. (Author)

    The European court rulings of 12 February 2003 raised considerable interest. Incineration in a French incinerator of domestic waste produced in Luxembourg was defined as 'disposal' while the use of industrial waste from Germany as substitute fuel in a Belgian cement plant was defined as 'utilisation'. In both cases, the waste producing countries had raised objections against the intended use. The contribution focuses on the Luxembourg decision, which is presented and discussed in detail. Effects in view of the eastward expansion of the EU are gone into. (orig.)

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.

    PBFA-II will produce 30 MV peak output voltage. A substantial portion of the output energy will be lost as free electrons which produce hard x-rays. Many x-rays will have energies within the photoneutron giant resonance. A PBFA-II shot will produce about 5 x 10 E14 photoneutrons. These photoneutron reactions will induce radioactivity in and about PBFA-II. Activation of structural components in the center section will be limited by substituting aluminum for stainless steel in regions of high x-ray intensity. Air will be activated above and below the center section after shots; however, x-ray shielding will limit initial concentrations to five times health guidelines. The short half-lives of air radioactivity will permit reentry following simple decay without ventilation. Some radioactive material will be eroded by arcing, but the resultant contamination should be small. Miniscule concentrations of radioactivity will be produced in the water surrounding the center section

    This paper describes the conceptual design of the reactor building and reactor maintenance building for the TIBER II tokamak. These buildings are strongly influenced by the reactor configuration, and their characterization allows a better understanding of the economic and technical implications of the reactor design. Key features of TIBER II that affect the facilities design are the small size and compact arrangement, the use of an external vacuum vessel, and the complete reliance on remote maintenance. The building design incorporates requirements for equipment layout, maintenance operations and equipment, safety, and contamination control. 4 figs

    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

    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.

    DECOVALEX II project started in November 1995 as a continuation of the DECOVALEX I project, which was completed at the end of 1994. The project was initiated by recognising the fact that a proper evaluation of the current capacities of numerical modelling of the coupled T-H-M processes in fractured media is needed not only for small scale, well controlled laboratory test cases such as those studied in DECOVALEX I, but also for less characterised, more complex and realistic in-situ experiments. This executive summary presents the motivation, structure, objectives, approaches, and highlights of the main tasks and main achievements of the DECOVALEX II project from 1995-1999. The main source of the materials came from four technical reports the project prepared by the project Secretariat, which, in turn, were based on numerous progress reports produced by a large number of international research teams over the three and half year period. The editors of this summary, together with the Steering Committee of the DECOVALEX II project, feel very encouraged by the progresses which have been made during the project time and very positive about the usefulness of the achievements reached by the project to the larger international community of scientific research and management of radioactive wastes in different countries. We sincerely hope that continued efforts be made to forward the research carried out in both DECOVALEX I and DECOVALEX II projects so that the disposal of radioactive waste could be managed on a more reliable scientific basis

    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.

    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

    Methanobactin (Mb) from Methylosinus trichosporium OB3b is a member of a class of metal binding peptides identified in methanotrophic bacteria. Mb will selectively bind and reduce Cu(II) to Cu(I), and is thought to mediate the acquisition of the copper cofactor for the enzyme methane monooxygenase. These copper chelating properties of Mb make it potentially useful as a chelating agent for treatment of diseases where copper plays a role including Wilson's disease, cancers, and neurodegenerative diseases. Utilizing traveling wave ion mobility-mass spectrometry (TWIMS), the competition for the Mb copper binding site from Ag(I), Pb(II), Co(II), Fe(II), Mn(II), Ni(II), and Zn(II) has been determined by a series of metal ion titrations, pH titrations, and metal ion displacement titrations. The TWIMS analyses allowed for the explicit identification and quantification of all the individual Mb species present during the titrations and measured their collision cross-sections and collision-induced dissociation patterns. The results showed Ag(I) and Ni(II) could irreversibly bind to Mb and not be effectively displaced by Cu(I), whereas Ag(I) could also partially displace Cu(I) from the Mb complex. At pH ≈ 6.5, the Mb binding selectivity follows the order Ag(I)≈Cu(I)>Ni(II)≈Zn(II)>Co(II)>>Mn(II)≈Pb(II)>Fe(II), and at pH 7.5 to 10.4 the order is Ag(I)>Cu(I)>Ni(II)>Co(II)>Zn(II)>Mn(II)≈Pb(II)>Fe(II). Breakdown curves of the disulfide reduced Cu(I) and Ag(I) complexes showed a correlation existed between their relative stability and their compact folded structure indicated by their CCS. Fluorescence spectroscopy, which allowed the determination of the binding constant, compared well with the TWIMS analyses, with the exception of the Ni(II) complex.

    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.

    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.

    PEP-II is a two-ring asymmetric B factory operating at the Upsilon(4S) resonance. It was constructed by a SLAC-LBNL-LLNL collaboration. The collider comprises two rings, a High-Energy Ring (HER) storing 9 GeV electrons, and a Low-Energy Ring (LER) storing 3.1 GeV positrons. Commissioning of the HER began in mid-1997 and commissioning of the LER began in mid-1998. First evidence for collisions was obtained on July 23, 1998. The BaBar detector was installed in early 1999, and commissioning with the detector commenced in May 1999. By September 1999, PEP-II had reached a peak luminosity of 1.35 x 10{sup 33} cm{sup {minus}2} s{sup {minus}1}. In the present run, which began in October 1999, the peak luminosity has reached 3.1 x 10{sup 33} cm{sup {minus}2} s{sup {minus}1} and the integrated luminosity delivered is 25 fb{sup {minus}1}. At present, PEP-II is the world's highest luminosity collider. In this paper we describe the startup experience and summarize the operational experience during fiscal year 2000 (from October 1999 through September 2000). Plan s for luminosity upgrades are briefly described.

    Full Text Available Fraser D RussellSchool of Health and Sport Sciences, Faculty of Science, Health and Education, University of the Sunshine Coast, Sippy Downs, Queensland, AustraliaAbstract: Cardiovascular function is modulated by neuronal transmitters, circulating hormones, and factors that are released locally from tissues. Urotensin II (UII is an 11 amino acid peptide that stimulates its’ obligatory G protein coupled urotensin II receptors (UT to modulate cardiovascular function in humans and in other animal species, and has been implicated in both vasculoprotective and vasculopathic effects. For example, tissue and circulating concentrations of UII have been reported to increase in some studies involving patients with atherosclerosis, heart failure, hypertension, preeclampsia, diabetes, renal disease and liver disease, raising the possibility that the UT receptor system is involved in the development and/or progression of these conditions. Consistent with this hypothesis, administration of UT receptor antagonists to animal models of cardiovascular disease have revealed improvements in cardiovascular remodelling and hemodynamics. However, recent studies have questioned this contributory role of UII in disease, and have instead postulated a protective effect on the cardiovascular system. For example, high concentrations of circulating UII correlated with improved clinical outcomes in patients with renal disease or myocardial infarction. The purpose of this review is to consider the regulation of the cardiovascular system by UII, giving consideration to methodologies for measurement of plasma concentrations, sites of synthesis and triggers for release.Keywords: urotensin II, cardiovascular disease, heart failure, hypertension

    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.

    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.

Co(II was extracted selectively to the extent of 80% into the 2-propanol phase at 5.0 M CaCl2. The percent of extraction of other transition metal ions, for example Mn(II, Ni(II and Cu(II was much lower than that of Co(II, but they were stripped in the aqueous phase upon addition of CaCl2. Therefore, selective extraction of Co(II from these metal ions was attained by using the mixture of water and 2-propanol. Co(II was extracted as CoCl42- from the aqueous phase into the 2-propanol phase through the formation of ion pair, Ca2+ - CoCl42-. A mechanism is proposed to explain the extraction.

  20. Structural alteration of hexagonal birnessite by aqueous Mn(II): Impacts on Ni(II) sorption

    Energy Technology Data Exchange (ETDEWEB)

    Lefkowitz, Joshua P.; Elzinga, Evert J.

    2017-09-01

    We studied the impacts of aqueous Mn(II) (1 mM) on the sorption of Ni(II) (200 μM) by hexagonal birnessite (0.1 g L- 1) at pH 6.5 and 7.5 with batch experiments and XRD, ATR-FTIR and Ni K-edge EXAFS analyses. In the absence of Mn(II)aq, sorbed Ni(II) was coordinated predominantly as triple corner-sharing complexes at layer vacancies at both pH values. Introduction of Mn(II)aq into Ni(II)-birnessite suspensions at pH 6.5 caused Ni(II) desorption and led to the formation of edge-sharing Ni(II) complexes. This was attributed to competitive displacement of Ni(II) from layer vacancies by either Mn(II) or by Mn(III) formed through interfacial Mn(II)-Mn(IV) comproportionation, and/or incorporation of Ni(II) into the birnessite lattice promoted by Mn(II)-catalyzed recrystallization of the sorbent. Similar to Mn(II)aq, the presence of HEPES or MES caused the formation of edge-sharing Ni(II) sorption complexes in Ni(II)-birnessite suspensions, which was attributed to partial reduction of the sorbent by the buffers. At pH 7.5, interaction with aqueous Mn(II) caused reductive transformation of birnessite into secondary feitknechtite that incorporated Ni(II), enhancing removal of Ni(II) from solution. These results demonstrate that reductive alteration of phyllomanganates may significantly affect the speciation and solubility of Ni(II) in anoxic and suboxic environments.

    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%.

    Full Text Available This study reports the results of the elucidation of the sorption-desorption mechanism of Zn(II and Cd(II on chitin through the determination of capacity, energy, and rate constant of sorption as well as the investigation of their desorption properties in NaCl and Na2EDTA solutions. The chitin was isolated through deproteination followed by demineralization of crab (Portunus pelagicus Linn shell using NaOH solutions. The sorption of both metal ions followed the Langmuir isotherm model, resulting the sorption capacities of 3.2 x 10-4 and 2.8 x 10-4 mol g-1 for Zn(II and Cd(II, respectively, and sorption energies of 15.1 kJ mol-1 for Zn(II and 17.9 kJ mol-1 for Cd(II. It was also observed that Zn(II was sorbed slightly faster than Cd(II with first order sorption rate constants of 2.82 x 10-3 min-1 for Zn(II and 2.61 x 10-3 min-1 for Cd(II. The result of the desorption experiment showed that Cd(II and especially Zn(II could only be exchanged by Na(I after desorbing those metal ions by strong chelating agent of EDTA2-. The easier desorption of Zn(II than Cd(II by EDTA2- must be attributed by the smaller sorption energy of Zn(II and by harder acid property of Zn(II than Cd(II as EDTA2- contained hard electron donor elements.   Keywords: sorption, desorption, chitin, Zn(II, Cd(II

    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

    Three novel copper(II), cobalt(II), and nickel(II) complexes of lapachol (Lap) containing 110-phenanthroline (phen) ligand, [M(Lap) 2 (phen)] (M=Cu(II), 1, Co(II), 2, and Ni(II), 3), have been synthesized and characterized using, elemental analysis and spectroscopic studies. Their interactions with calf thymus DNA (CT DNA) were investigated using viscosity, thermal denaturation, circular dichorism, fluorescence quenching, and electronic absorption spectroscopy. The DNA cleavage abilities of 1-3 have been studied, where cleavage activity of copper complex 1 is more than the complexes 2 and 3. The in vitro cytotoxic potential of the complexes 1-3 against human cervical carcinoma (HeLa), human liver hepatocellular carcinoma (HepG-2), and human colorectal adenocarcinoma (HT-29) cells indicated their promising antitumor activity with quite low IC 50 values in the range of .15-2.41 μM, which are lower than those of cisplatin.

    The main objective of this work is to prepare a renewable cellulosic adsorbent by γ-initiated grafting of poly(glycidyl methacrylate) (PGMA) from cellulose substrate and subsequent modification of PGMA with chelating species, iminodiacetic acid (IDA), for Cd (II), Pb(II) and Cu(II) removal from aqueous media. Modification of PGMA grafted cellulose with IDA in aqueous solution under mild conditions has proceeded efficiently to yield a natural-based and effective porous adsorbent with well-defined properties as provided by the controlled polymerization technique, namely RAFT, applied during the radiation-induced graft copolymerization step and with sufficient degree of IDA immobilization as confirmed by XPS, FTIR, contact angle measurements and elemental analysis. In order to examine the Cd (II), Pb(II) and Cu(II) removing performance of the resulting adsorbent, batch experiments were carried out by ICP-MS. The adsorption capacities were determined as 53.4 mg Cd(II)/g polymer, 52.0 mg Pb(II)/g polymer and 69.6 mg Cu(II)/g polymer at initial feed concentration of 250 ppm, showing the promising potential of the natural-based adsorbent to steadily and efficiently chemisorb toxic metal ions.

    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 approximately 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.

    Full Text Available Fixed functional appliances have gained the popularity for growth modification in noncompliant patients, especially hybrid types. But for this, clinicians have to depend on certain commercially available appliances; otherwise components required in fabrication of hybrid type appliances are not routinely available in clinics, which discourage their, use. Additionally, these preformed appliances have less scope in changing their length as per patient′s requirement of particular mandibular advancement. This article explains the chairside fabrication of open coil NiTi spring loaded hybrid type fixed functional appliance named ′Vibhute Class II Correction Appliance′ (VCCA. This custom-made tinier and hygienic design provides stable fixation, less breakages with increased range of mandibular movement involving unrestricted mouth opening. VCCA permits quick chairside fabrication with ease in installation of appliance and is inexpensive.

    A 540-kW continuous-wave (cw) klystron operating at 476 MHz was developed for use as a power source for testing PEP-II rf accelerating cavities and rf windows. It also serves as a prototype for a 1.2 MW cw klystron presently being developed as a potential rf source for asymmetric colliding ring use. The design incorporates the concepts and many of the parts used in the original 353 MHz PEP klystron developed sixteen years ago. The superior computer simulation codes available today result in improved performance with the cavity frequencies, drift lengths, and output circuit optimized for the higher frequency.The design and operating results of this tube are described with particular emphasis on the factors which affect efficiency and stability

    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

    Refractory septic shock is defined as persistently low mean arterial blood pressure despite volume resuscitation and titrated vasopressors/inotropes in patients with a proven or suspected infection and concomitant organ dysfunction. Its management typically requires high doses of catecholamines, which can induce significant adverse effects such as ischemia and arrhythmias. Angiotensin II (Ang II), a key product of the renin-angiotensin-aldosterone system, is a vasopressor agent that could be used in conjunction with other vasopressors to stabilize critically ill patients during refractory septic shock, and reduce catecholamine requirements. However, very few clinical data are available to support Ang II administration in this setting. Here, we review the current literature on this topic to better understand the role of Ang II administration during refractory septic shock, differentiating experimental from clinical studies. We also consider the potential role of exogenous Ang II administration in specific organ dysfunction and possible pitfalls with Ang II in sepsis. Various issues remain unresolved and future studies should investigate important topics such as: the optimal dose and timing of Ang II administration, a comparison between Ang II and the other vasopressors (epinephrine; vasopressin), and Ang II effects on microcirculation.

    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.

    Full Text Available INTRODUÇÃO: A obesidade pode afetar o tórax, diafragma e músculos abdominais, determinando alterações na função respiratória. OBJETIVO: Avaliar os efeitos da obesidade e correlacionar o índice de massa corporal (IMC e a circunferência abdominal com os valores espirométricos em individuos obesos. MÉTODO: Foram estudados 48 indivíduos não obesos e 48 indivíduos com obesidade graus I e II, não fumantes, ambos os sexos, idade variando entre 18 e 75 anos, IMC entre 30 e 40kg/m² e ausência de história progressa de morbidade. Foram realizadas espirometria e medidas da circunferência abdominal. RESULTADOS: Não houve diferenças significativas quando se comparou valores espirométricos de homens com obesidade graus I e II com de não obesos. Nas mulheres obesas, a capacidade vital forçada e o volume expirado forçado no primeiro segundo foram significativamente menores que nas não obesas. Homens e mulheres obesos apresentaram volumes de reserva expiratório significativamente menores que não obesos. Embora a capacidade inspiratória tenha sido maior em homens e mulheres obesos, esse aumento foi significativo apenas em homens. Em homens obesos houve correlação negativa e significativa entre o IMC e circunferência abdominal e o volume de reserva expiratório, e também correlação negativa e significativa entre a circunferência abdominal e o volume expirado forçado no primeiro segundo, o que não ocorreu entre as mulheres. CONCLUSÃO: Mulheres com obesidade graus I e II apresentaram alterações na função pulmonar. Esta não é influenciada pelo IMC em homens obesos. No entanto, observou-se que eles apresentaram correlação negativa e significativa entre o IMC e o volume de reserva expiratório. A função pulmonar é influenciada pelos valores da circunferência abdominal em homens com obesidade graus I e II.BACKGROUND: Obesity can effect the thorax, diphragm and abdominal muscles, thereby resulting in altered respiratory

    Full Text Available Neste trabalho, objetivou-se estudar a seletividade de imazapic a dois cultivares de amendoim (Tatu Vermelho e IAC-5, em condições de ausência e de presença de palha de cana-de-açúcar. O experimento foi instalado em vasos, em delineamento inteiramente casualizado, com os tratamentos dispostos em esquema fatorial 3x2, com quatro repetições. Constituíram os fatores principais três doses de imazapic (0, 98 e 140 g ha-1, aplicadas em pré-emergência sobre duas condições de palha de cana-de-açúcar (0 e 15 t ha-1. Constatou-se que a camada de palha possui potencial em reter o herbicida, especialmente sob períodos de pouca precipitação ou irrigação; as plantas de amendoim sob esta condição apresentaram menos sintomas de intoxicação. Entretanto, na ausência da palha, as plantas, independentemente do cultivar, apresentaram maiores injúrias visuais e redução na altura, massa seca da parte aérea e raiz.This research aimed to evaluate imazapic selectivity for two peanut cultivars (Tatu Vermelho and IAC with and without sugarcane straw. The experimental design was completely randomized arranged in a3x2 factorial scheme with four replicates. The experiment was set in plastic pots and the treatments consisted of a combination of three rates of imazapic applied in pre-emergence (0, 98, and 140 g ha-1, and two levels of sugarcane straw (0 and 15 ton ha-1. The straw layer retained the herbicide, mainly under little precipitation or irrigation periods; under these conditions, peanut plants showed fewer intoxication symptoms. However, without the straw,the plants showed larger visual injuries and reduction in height, aerial parts and root dry mass for both peanut cultivars and herbicide rates.

    The IMSAS is working on an actively heated Si substrate with interdigital structures fo working temperatures up to 550 C and for aggressive working media. The following tasks were achieved: Gas sensor design; Process development and optimisation; Processing of the Si substrate; Optimisation of the sensor substrate. The following problems were encountered: Minimisation of intrinsic stress of the stratified packages; Optimisation of the adhesive strength; Development of a stable sensor heating up to 550 C; Development and optimisation of structuring methods; Combination of thin film and thick film technologies. Resistive gas sensors with titanium-tungsten mixed oxides must be heated to 500 C for fast and sensitive response to a NO atmosphere. The gas sensitivity is strongly temperature-dependent, i.e. gas sensor temperature contro is required. In the case of diesel engine catalytic converters, ambient temperatures are high and vary with the mode of operation and operating time. The sensor temperature must be at least as high as the maximum ambient temperature and must be kept stable at this level. (orig.)

    Aim of this project was the development of high temperature construction materials for systems to the environmentally friendly power transformation based on the NiAl-Alloy IP 75, as well as the production methods for thin walled profile parts by Metal-Injection-Moulding (MIM). Starting from the powder specification a method should be worked out to sinter injected parts according to the requested properties, reached densities, shrinkage and behaviour. The advantages of NiAl-Alloys lie in the high melting point as well as the oxidation resistance, caused by passivating oxide layer. From production point of view these characteristic represent obstacles which had to be overcome. Further advantages of the materials lie in the chemical resistance and in the good mechanical properties at high temperature which permits special application under extreme conditions e.g. Stirling engine. Components of this materials were produced which a density of ca. 99% of the theoretical density. A fundamental feasibility regarding the production of components on NiAl-base by the MIM-Technology is given. (orig.) [German] Ziel dieses Projektes war die Entwicklung von Hochtemperaturkonstruktionswerkstoffen fuer Systeme zur umweltfreundlichen Energieumwandlung aus NiAl-Basislegierung IP 75 (45 at.% Ni, 45 at.% Al, 7,5 at.% Cr und 2,5 at.% Ta) sowie deren Herstellungsmethoden fuer duennwandige (bis zu groesseren Abmessungen) Profilteile mittels der Metal-Injection-Moulding-Technologie (MIM). Ausgehend von der Pulverspezifikation sollte im Projekt ein Verfahren erarbeitet werden, um spritzgegossene Bauteile den Anforderungen entsprechend zu sintern. Hierbei ging es vor allen Dingen um Werkstoffeigenschaften, erreichte Dichten und Schwinungsverhalten. Die anwendungstechnischen Vorteile des NiAl-Systems liegen in dem hohen Schmelzpunkt sowie dem stabilen Oxidationsverhalten, das seinerseits durch die Bildung stabiler Oxidschichten begruendet ist.

    Full Text Available BACKGROUND: A razão por que aproximadamente 10% das pessoas que cometem suicídio parecem ser psiquiatricamente normais ainda não está clara. Para melhor compreender este assunto, estudamos suicidas sem diagnóstico do eixo I e os comparamos com controles normais e com suicidas com psicopatologia do eixo I no que diz respeito a outras psicopatologias. MÉTODOS: 168 casos de suicídio foram examinados por meio de autópsia psicológica com o melhor informante disponível. Dezesseis casos não preencheram os critérios para um diagnóstico do eixo I; cada um desses casos foi pareado em idade e gênero com 52 casos de suicídio com transtorno do eixo I e com 110 controles normais. RESULTADOS: Dos 16 casos de suicídio, 14 pacientes sem diagnóstico do eixo I apresentaram anormalidades detectáveis à autópsia que eram mais semelhantes às encontradas nos pacientes suicidas com diagnóstico de eixo I do que no grupo vivo. Os dois grupos suicidas mostraram semelhanças no número total de tentativas prévias de suicídio, no número total de indivíduos com transtornos do eixo II e nos escores obtidos na medida dos comportamentos impulsivo-agressivos. CONCLUSÕES: Estes achados sugerem que a maioria dos indivíduos que cometeu suicídio e aparentou ser psiquiatricamente normal na autópsia psicológica possivelmente possuía algum processo psiquiátrico subjacente que o método da autópsia, da maneira como é comumente realizado, falhou em detectar.JUSTIFICATIVA: Todavía no está claro por qué un 10% de las personas que cometen suicidio parecen ser psiquiátricamente normales.

    Immunotherapy is an exciting development in lung cancer research. In this study we described major histocompatibility complex (MHC) Class II protein expression in lung cancer cell lines and patient tissues. We studied MHC Class II (DP, DQ, DR) (CR3/43, Abcam) protein expression in 55 non-small cell lung cancer (NSCLC) cell lines, 42 small cell lung cancer (SCLC) cell lines and 278 lung cancer patient tissues by immunohistochemistry (IHC). Seven (12.7%) NSCLC cell lines were positive for MHC Class II. No SCLC cell lines were found to be MHC Class II positive. We assessed 139 lung cancer samples available in the Hirsch Lab for MHC Class II. There was no positive MHC Class II staining on SCLC tumor cells. MHC Class II expression on TILs in SCLC was significantly lower than that on TILs in NSCLC (P<0.001). MHC Class II was also assessed in an additional 139 NSCLC tumor tissues from Medical University of Gdansk, Poland. Patients with positive staining of MHC Class II on TILs had longer regression-free survival (RFS) and overall survival (OS) than those whose TILs were MHC Class II negative (2.980 years, 95% CI 1.628-4.332 vs. 1.050 years, 95% CI 0.556-1.554, P=0.028) (3.230 years, 95% CI 2.617-3.843 vs. 1.390 years, 95% CI 0.629-2.151, P=0.014). MHC Class II was expressed both in NSCLC cell lines and tissues. However, MHC Class II was not detected in SCLC cell lines or tissue tumor cells. MHC Class II expression was lower on SCLC TILs than on NSCLC TILs. Loss of expression of MHC Class II on SCLC tumor cells and reduced expression on SCLC TILs may be a means of escaping anti-cancer immunity. Higher MHC Class II expression on TILs was correlated with better prognosis in patients with NSCLC. Copyright © 2017. Published by Elsevier B.V.

    The localization of Angiotensin II (Ang II) receptors in the Amphibia kidney was investigated by radioautography and binding studies. 125 I-Ang II was injected into the dorsal aorta of anesthetized toads, Calyptocephalella caudiverbera. The kidney excised 2 and 10 min after injection show intense labeling in the glomeruli and a lesser amount in the tubules. Ang II labeling was found in the proximal, distal and collecting tubules. The thin connecting segment (diluting segment) also shows a distinct labeling. Afferent and efferent arterioles and interstitial connective tissue do not show radioautographic granules above the background level. Ang II binding studies of glomerular and tubular membranes show that the binding of 125 I-Ang II is higher in the glomerular than in the tubular membranes with a Kd of 1.9 x 10 -9 M and 1.0 x 10 -9 M respectively. Their results show that angiotensin II receptors in the amphibian nephron are present in the glomeruli and tubular segments, supporting the hypothesis of the intrarenal action of Ang II in this group of vertebrates
