In Fragebogen-Untersuchungen zur Lärmwirkung wurden bisher sehr unterschiedliche Operationalisierungen von Wirkungsvariablen (wie z.B. Belästigung, Störung von Aktivitäten) und außer-akustischen Faktoren (sog. Moderatoren wie z.B. Lärmempfindlichkeit, misfeasance) verwendet. Deshalb hat sich die Arbeitsgruppe community response der International Commission on the Biological Effects of Noise (ICBEN, Team No. 6) als langfristiges Ziel die Entwicklung von Fragebogen-Guidelines und die Formulierung eines Muster-Fragebogens für die Lärmwirkungsforschung gesetzt. D.h. es soll ein Vorschlag erarbeitet werden, in welcher Form globale und spezifische Lärmwirkungen in Befragungen erhoben werden sollten. Um dieses Vorhaben zu unterstützen, hat der Arbeitskreis Ökologische Lärmforschung die Erstellung einer systematischen Übersicht über vorhandene Fragebögen aus Lärmwirkungsstudien auf internationaler Ebene in Angriff genommen. Diese Übersicht soll es u.a. ermöglichen, die Struktur von verschiedenen Fragebögen sowie die in ihnen verwendeten Operationalisierungen für Lärmwirkungs- und Moderatorvariablen (hinsichtlich Art der Frageformulierung sowie der Antwortformate) zu vergleichen. Für den/die einzelne/n Lärmforscher/in bietet diese Übersicht die Möglichkeit, sich auf sehr effiziente Art und Weise darüber zu informieren, wie bestimmte Konstrukte in bisherigen Untersuchungen operationalisiert worden sind bzw. welche Alternativen zu den bereits selbst angewandten Operationalisierungen bestehen. Nach einer systematischen Ermittlung von Namen und Adressen einschlägiger Lärmforscher/innen, wurden diese um die Zusendung von Fragebögen sowie ergänzender Materialien aus eigenen Lärmwirkungsstudien gebeten. Die zugesandten Fragebögen werden gegebenenfalls übersetzt und mit der Methode der qualitativen Inhaltsanalyse ausgewertet. Hierbei werden die Fragebögen im Hinblick auf formelle Aspekte (z.B. Jahr der Erhebung, Sprache, Art der Befragungsmethode) wie auch im Hinblick auf strukturelle Aspekte (z.B. Umfang des Fragebogens, abgefragte Variablengruppen, Antwortformate) ausgewertet. Hauptgegenstand der Auswertung ist aber insbesondere die Auswertung der Lärmwirkungsvariablen (z.B. die Abfrage der globalen Lärmbelästigung, Aktivitätenstörungen, Kommunikationsstörungen) sowie der Moderatorvariablen (z.B. Lärmempfindlichkeit, Lärmbewältigungsvermögen, misfeasance). Parallel dazu wurde eine Datenbank entwickelt, in der die Ergebnisse der Analysen dargestellt und verwaltet werden. Diese Datenbank wird ab November 2001 im Internet unter http://www.eco.psy.ruhr-uni-bochum.de/nqd für jede/n interessierte/n Forscher/in zugänglich und nutzbar sein. Langfristig ist darüber hinaus geplant, ein Archiv mit den Original-Fragebögen aufzubauen, in dem einzelne Fragebögen auf Wunsch eingesehen werden können.
Non wood fuels for small-scale furnaces have attracted increasing interest in several European countries. New technological approaches are on the way, but the verification of any such developments is difficult and there is a large uncertainty about testing procedures and equipment. While for wood combustion standardized European measuring regulations are available and broadly applied, the testing of cereal fuel combustion is generally not following a commonly accepted procedure. Consequently the results of such measurements are not fully comparable. This applies particularly for the international level, which is here of particular relevance due to the fact that a combustion technology development for a niche application can only be economically viable if a sufficiently large marketing area can be taken into focus. The overall objective of the proposal is therefore to contribute through research to the development of uniform and comparable European procedures for testing of small-scale boilers up to a power out of 300 kW for solid biomass from agriculture like straw pellets and energy grain. The driving forces and barriers will be worked out; existing legal regulation for the installation (approval by the local authorities) in the participating countries will be collected. The state of the art of the non wood biomass boiler technology will be identified; the need for standardized tests for type approval tests and the measures to establish a European Standard will be shown. Measurement methods with special emphasis on efficiency and emissions will be worked out and the requirements and specifications of test fuels will be proposed. Test runs will be carried out following preliminary test procedures based on existing European standards for wood boilers. Based on the results of these test runs a draft for a Europe-wide uniform test procedure will be proposed. Preparatory work for a European standardization process including a round robin test will be done.
MAI-TAI deals with integrated water resources management. It is designed as a coordination action of leading research and innovation operators, aiming at developing a coherent set of innovative, relevant and cooperative policy options and management strategies. Regionally it works with partners from China and India, and the work will focus around two lead river basins: The Hai river basin in North-East China and the Yamuna river basin in North India, both in arid and/or semi arid regions. The proposal features the following core coordination activities: 1. Enabling a dialogue between researchers and practitioners promoting state of the art and indigenous technologies and practices: The consortium believes that modern systems alone are not capable of solving the water needs of the people in many developing countries, and there is a strong need of generating innovative options through cross fertilization between both worlds. This cross-fertilization will be enabled by methods and rich experiences of user innovations research. 2. Based on (1), innovative policy options and management strategies will be compiled. Then, a multi-stakeholder interaction in order to evaluate these options and strategies will be carried out, supported by intelligent knowledge management tools: In the presence of a variety of actors (institutions, organisations, individuals) each with specific forms of knowledge with respect to scale, topic, reasoning processes, and a large number of information expected to be generated through the multi-stakeholder interaction, the issue of learning and knowledge management is of paramount importance. A strong impact of the coordination action is ensured by a highly inter- and transdisciplinary team, encompassing internationally reputable scientific institutions as well as strong governmental partners and NGOs. The latter two will considerable facilitate a wide and in particular meaningful stakeholder dialogue throughout the project.
Various layers exist in the summer mesosphere at middle and polar latitudes which owe their existence to water ice particles. These layers are called ‚noctilucent clouds' (NLC), ‚polar meso- sphere clouds' (PMC), and ‚polar mesosphere summer echoes' (PMSE) which reflects different observation geometry or entirely different physical processes involved. These layers are very sen- sitive to temperature (and to a lesser extent to H2O) and are therefore best suited to indicate long term and solar cycle changes. Indeed, variations on decadal time scales of different layer parameters (occurrence frequency, layer brightness etc.) have been reported from ground and satellite based observations. However, the physical and photo-chemical processes involved are not understood and some of the observations contradict expectations. In this proposal we want to study the long term (decadal scale) formation of layers in the polar summer mesopause region, in particular their sensitivity to variations of background conditions caused by solar forcing and anthropogenic increase of greenhouse gases. We investigate and complement the available observations on layers (NLC/PMC/PMSE) and trace gases (ground based microwave and satellite observations of H2O) and perform model calculations with the LIMA GCM model. In the third phase of the SPP we want to study in particular the feed back mechanisms of ice formation on the atmosphere (e. g., through freeze drying) and the coupling mechanisms to above and below.
Ziel des Forschungs- und Entwicklungsprojekts ist die Planung und Umsetzung eines integralen Energie- und Sanierungskonzepts für das 1887 in Braunschweig eröffnete Herzog-Anton-Ulrich-Museum. Unter Mitwirkung aller Projektbeteiligten werden die für die Sanierung relevanten Themengebiete Bauphysik, Raumklima, Heizung und Lüftung, Tages- und Kunstlicht untersucht. Der Einhaltung der für die Exponate maßgeblichen geringen Toleranzen in Bezug auf Feuchte und Temperatur kommt in diesem Zusammenhang besondere Bedeutung zu. Durch das Sanierungskonzept soll eine erhebliche Reduktion des Heizenergie- und elektrischen Stromverbrauchs erreicht werden (Heizenergie: - 35 Prozent, Strom für Beleuchtung, Belüftung und Befeuchtung: - 50 Prozent ). Weiterhin sollen die thermische und visuelle Behaglichkeit und die konservatorischen Randbedingungen für die Exponate verbessert werden. Dabei stehen eine Verbesserung der Gebäudehülle (Herstellung der Luftdichtheit, Einsatz optimierter Verglasungen etc.) und die Vermeidung sommerlicher Überhitzung im Vordergrund. Zur Umsetzung einer weitestgehend natürlichen Klimatisierung wird auch die Reaktivierung des vorhandenen Hypokausten-Systems geprüft. Die Konzepte werden seit Oktober 2000 durch Messungen und Computersimulationen geprüft und validiert. Nach der Sanierung folgt eine einjährige Monitoring- und Evaluierungsphase. Das Sanierungsprojekt für das Herzog-Anton-Ulrich Museum zeigt die vielfältigen Möglichkeiten, wie im behutsamen Umgang mit historischer Bausubstanz die klimatischen und visuellen Anforderungen an Museen optimiert und gleichzeitig erhebliche Energieeinsparungen realisiert werden können.
The aim of this research project is to establish the basis for deriving a consistent set of probabilistic models for strength and stiffness related timber material properties and to calibrate corresponding partial safety factors such that the level of structural reliability for timber structures is equivalent to the safety of concrete and steel structures. This seen in the light of the ongoing revision of the national Swiss codes for the design of structures. CONCLUSIONS/PERSPECTIVES: The statistical characteristics of strength related short term timber material properties are assessed and treated in consistency with the implemented quality control and selection for grading procedures. The suggested probabilistic modelling seems to provide the required framework for establishing a basis for codification of design and assessment by means of quantifying the efficiency of the different quality control and selection for grading procedures. It is envisaged that different quality control and selection for grading procedures may be described by means of their regression characteristics and probability of acceptance curves corresponding to different grading criteria. It also has been demonstrated how an optimal (in terms of monetary benefit) set of timber grades can be identified through the solution of an optimization problem. An approach for the probabilistic modeling of the effect of load duration is presented. The method is exemplified for calibrating the design code short term strength modification factor kmod for different characteristics of the applied loading process. The considered damage model takes basis in fracture mechanical considerations and is able to take both creep and fatigue effects into account. The damage model is calibrated against duration of load tests. Furthermore, the damage model has been investigated and compared with a simpler model not including the effect of fatigue. A proposal for a proper representation of the duration of load effect in the probabilistic model code of the Joint Committee on Structural Safety will be subject of further investigations.
One of the guiding principles of Priority 6.3 Global Change and Ecosystems is to promote scientific research to provide support to the EU Strategy for Sustainable Development. The capitalisation process, in the way that it has been conceived in Multagri SSA, addresses several aspects directly related with the objectives of this Strategy. The aim of this proposal is to provide a complete overview of the research that has been done, particulary in Europe, in the different aspects related to Multifonctionality of agriculture. The essential approach adopted in this initiative is founded on the premise that for agriculture to be sustainable its multifonctional dimension must be acknowledged and promoted. Previous works have primitted the identification of the main axes in which the state-of-the-art review will be developed. The proposed framework of analysis has considered mutiple topics that are the subject of research on multifunctionality of agriculture and shape some of the current debates on this notion, such as definitions and interpretations of this term, production systems that privilege the provision of certain functions, methodologies and tools to assess the different roles of agriculture, institutional settings to acknowledge them, societal demands for additional goods and services from agriculture and related policy making and evaluation. Issues such as equitable regional development, food secutity and safety, natural resource conservation, rural income generation and global sustainability - explicitly revealed in the Strategy for Sustainable Development as key concerns - , are covered by the concept of Multifunctionality of agriculture, and therefore, make part of the analysis of the state-of-the - art proposed by Multagri SSA. By providing a set of recommendations on futur research, this proposal will contribute to strenghten the necessary scientific knowledge for the future orientation of the SD strategy and the 6th FP.

The aim of the project is to encourage the concerned stakeholders in Least Developed Asian Countries (LDACs) to formulate and apply sustainable methods of management of Municipal Solid Waste (MSW), with special focus on safe landfilling, based on local conditions, socio-economic settings and technical capabilities, considering Bangladesh as case study country. The findings of WasteSafe, a previously completed feasibility study project of ECs Asia Pro Eco Programme, are used as the backbone of this demonstration project. Dr. Roehl is involved as External Experts in this project.
The CityNet project cluster consists of six individual 5 FWP projects and deals with the integrated aspects of water management in urban areas (water supply, sewerage, drainage) including their urban/rural interfaces (raw water sources, receiving waters, groundwater). The CityNet cluster consists of 47 research partners and 59 end-users, thus comprising a significant part of the European R&D capacity and implementation potential in urban water systems. This proposal for Accompanying Measures (AM) aims to widen and deepen the joint activities of the cluster partners with respect to three aspects of integration, i.e. (1) the urban water system and its water resources, (2) the necessary infrastructure for water supply, urban drainage and wastewater management, and (3) the socioeconomic aspects of urban water management. The overall scope of the AISUWRS initiative is to assess and improve the sustainability of urban water resources and systems with the help of computer tools. The project will analyse a range of existing urban water supply and disposal scenarios by demonstrating how each scenario differs in its handling of contaminants within different urban water systems and the potential effect of these contaminants on groundwater contamination. For the verification and validation of the models, detailed field studies are carried out in three European and one Australian case study city. In addition AISUWRS aims to develop also a management and Decision Support System to deliver detailed guidelines and recommendations for the safeguarding and protection of urban water resources.
Under the 2003 EU Greek presidency, cooperation with Balkan countries on environmental issues was identified as a priority of the EU/Balkan Action Plan. Large-scale co-operation is essential for effective action in the vulnerable Mediterranean and Black Sea coastal zones. During the last 50 years both areas suffered major changes; as semi-enclosed basins, both Seas are ultra-sensitive to anthropogenic stress and to climate change. An EU Presidency Conference on Sustainable Development in the Mediterranean/Black Sea (May 2003), revealed major gaps in management structures, scientific strategies and identified a diversity of environmental issues to be resolved through priority-focused RTD cooperation. Yet, while pressure on the resources of the two seas increases and the potential impact of climate change on coastal and deep-sea resources remains unknown, the two seas have never been jointly studied as systems of interacting basins and ecosystems. The proposal outlines collaboration and clustering schemes involving environmental, economic and scientific organisations in Mediterranean, Black Sea and other EU nations, in order to create synergies in networking and exchanges at several levels, addressing for the first time the system of interconnected basins as one, based on the integration of, both horizontally and vertically, natural scientists and economists. These will: 1) Create an international, interdisciplinary platform coordinating the region's scientific potential in order to prepare RTD projects, based on a Science Plan for the region, securing sustainable development; 2) Focus on natural and anthropogenic pressures exerted upon the functioning of the ecosystem; 3) Reinforce RTD capacity by setting up an environment/resource monitoring network in the light of existing observation networks of different scopes.
