Objective: Nano-scale objects interact with living organisms in a fundamentally new manner, ensuring that a fruitful marriage of nanotechnology and biology will long outlast short term imperatives. Therefore, investment in an infrastructure to drive scientific knowledge of the highest quality will have both immediate benefits of supporting the safety assessment of legacy nano-materials, as well as pointing towards future (safe) applications with the lasting benefits to society. There are immediate priorities, for few doubt that serious damage to confidence in nanotechnology, unless averted, could result in missed opportunities to benefit society for a generation, or more. QNano will materially affect the outcome, at this pivotal moment of nanotechnology implementation. The overall vision of QNano is the creation of a 'neutral' scientific & technical space in which all stakeholder groups can engage, develop, and share scientific best practice in the field. Initially it will harness resources from across Europe and develop efficient, transparent and effective processes. Thereby it will enable provision of services to its Users, and the broader community, all in the context of a best-practice ethos. This will encourage evidence-based dialogue to prosper between all stakeholders. However, QNano will also pro-actively seek to drive, develop and promote the highest quality research and practices via its JRA, NA and TA functions, with a global perspective and mode of implementation. QNano will also look to the future, beyond the current issues, and promote the growth and development of the science of nano-scale interactions with living organisms. By working with new and emerging scientific research communities from medicine, biology, energy, materials and others, it will seek to forge new directions leading to new (safe, responsible, economically viable) technologies for the benefit of European society.
Achievements:The EUROBALT project has led to the advancement of knowledge in the behaviour of ballasted track in several different areas. The measurements have shown the importance of the track stiffness in the whole process of the track degradation. Even though a complete understanding has not been achieved in this particular area, this concept will be now considered by the railways companies. Different tools have also been improved or developed in order to measure the track stiffness, under traffic or by separate investigation (STEDEF measurement technique or PANDROL double integration). Modelling the ballast has been investigated with first studies with new approaches (ENPC). Moreover, two models have been developed, with the same goal of predicting track geometry deterioration. Even though the validation has been limited, it is a big step forward in the study of the phenomena (INRETS 'VOCO + BALTAS' and TUB SIRaGe). As for the models of track damage modelling, different problems were studied and models were developed or improved. These models will also allow a better understanding of the phenomena of track deterioration and the prediction of maintenance and renewal requirement and costs (BRR models). The monitoring studies led to : the development of a prototype able to recover in real time the long wave faults on a track, using versine based measurement cars (MAN technique), the development of a calculation method to define the forces applied on a track section when a train passes, using the data obtained from the new piezofoil sensors developed within the project (MAN method and TUB piezofoil sensors applications). What is also important is the knowledge gained by the different participants, particularly the railways companies. The different approaches used to characterise the behaviour of the ballast showed that the parameters are numerous and not easy to resolve. It can be stated, however, that the concepts of track elasticity or track elasticity variation is one of the key factors in track geometry deterioration. Further studies must be led now to describe more precisely its importance, define means of measurement, and develop the track specifications necessary to realise the benefits that are possible. The EUROBALT project is a big step forward in providing a more precise knowledge of the ballasted track. A complete understanding, however, remains elusive, and is likely to require significant further investigations. .

Objective: The project will examine the health impacts of greenhouse gas (GHG) reduction policies in urban settings in Europe, China and India, using case studies of 3-4 large urban centres and three smaller urban centres. Sets of realistic interventions will be proposed, tailored to local needs, to meet published abatement goals for GHG Emissions for 2020, 2030 and 2050. Mitigation actions will be defined in four main sectors: power generation/industry, household energy, transport and food and agriculture. The chief pathways by which such measures influence health will be described, and models developed to quantify changes in health-related 'exposures' and health behaviours. Models will include ones relating to outdoor air pollution, indoor air quality and temperature, physical activity, dietary intake, road injury risks and selected other exposures. Integrated quantitative models of health impacts will be based on life table methods encompassing both mortality and morbidity outcomes modelled over 20 year time horizons. Where possible, exposure-response relationships will be based on review evidence published by the Comparative Risk Assessment initiative or systematic reviews. Uncertainties in model estimates will be characterized using a mathematical framework to quantify the influence of uncertainties in both model structure and parameter estimates. Particular attention will be given to economic assessments, both in terms of behavioural choices/uptake of various forms of mitigation measure (with new surveys to address evidence gaps), and in terms of health benefits and costs calculated from societal, health service and household perspectives. A decision analysis framework will be developed to compare different mitigation options. Experts and user groups will be consulted to define the mitigation questions to be examined, and the results will be discussed in consultative workshops scheduled for the final months of the project.
Drying, through its effects on soils, is likely to affect any man-made structure and building supported by the ground, as well as the safety of earth structures (such as flood embankments and dams) and land use. The related human and financial costs are incalculable. Studies on climate global change clearly suggest an increasing recurrence of drought events in some parts of the world, making the subject a burning issue. The broad objective of the research is twofold: (i) to gain a better understanding of the consequences of drying the soil, the mechanisms which induce damage and the variables which control it; (ii) to develop a comprehensive predictive model, able to assess such processes. Because of the deformable nature of soils, drying primarily induces shrinkage. More generally, drying is responsible for a large set of processes, which could be sorted as follows: (i) soil de-formation, (ii), strength modification, (iii), structure alteration, (iv), mechanical damage, and (v) fracture. The risks of degradation of buildings, of earth-structures and land use stem from these phenomena. In spite of the existing modelling capabilities, the prediction of the consequences of drying on soil behaviour is still oversimplified. This is primarily because of the lack of global conceptual models for the highly complex processes that occur during drying. We intend to tackle the problem by considering the fundamental couplings between the water retention behaviour and the mechanical behaviour. The structure changes and damages induced by drying will be the focus of our attention. In order to support our understanding of the processes and their modelling, it is planned to conduct experiments, and to measure the evolution of deformation, water saturation, particle arrangement and fracturing related to drying. The work and its planned dissemination will help communities to assess the potential environmental impact and risk on their territory more easily. This research will develop a coherent and experimentally-supported theory. Understanding soil drying shrinkage and damage and developing abilities to predict its behaviour will allow engineers to reduce the principal threat to landforms and structures. This alone will be greatly beneficial to a large portion of the population.
Objective: As consumption of psychoactive substances such as alcohol, drugs and certain medicines are likely to endanger the drivers aptitude and impaired driving is still one of the major causes for road accidents, some active steps have to be taken to reach the goal of a 50% reduction in the number of road deaths in the EU. The objective of DRUID is to give scientific support to the EU transport policy to reach the 2010th road safety target by establishing guidelines and measures to combat impaired driving. DRUID will - conduct reference studies of the impact on fitness to drive for alcohol, illicit drugs and medicines and give new insights to the real degree of impairment caused by psychoactive drugs and their actual impact on road safety - generate recommendations for the definition of analytical and risk thresholds - analyse the prevalence of drugs and medicines in accidents and in general driving, set up a comprehensive and efficient epidemiological database.
Derzeit werden verschmutzte Fassaden meist mit Strahlverfahren gereinigt, bei denen entweder Wasser oder Gemische aus Wasser, Luft und festen Strahlmitteln eingesetzt werden. In Spezialfällen (z.B. bei der Graffitientfernung) werden auch toxikologisch und ökologisch nachteilige organische Lösemittel eingesetzt, wobei aufwändige Zusatzmaßnahmen des Arbeits- und Umweltschutzes erforderlich sind. Ein Nachteil der praxisüblichen wässrigen Strahlverfahren sind die hohen Personal- und Betriebskosten. Derartige Verfahren erfordern hohe Wassermengen, so dass in großem Umfang schadstoffbelastete Abwässer resultieren. Diese dürfen aufgrund der umweltrechtlichen Vorschriften nicht unaufbereitet in die Kanalisation bzw. in die Oberflächengewässer geleitet werden, sondern müssen je nach Schadstoffbelastung zusammen mit den eingesetzten Strahlmitteln aufwändig und zu hohen Kosten aufgefangen und aufbereitet bzw. entsorgt werden. Ferner führt der Einsatz wasserintensiver Fassaden-Reinigungs-verfahren je nach Porosität der Materialien zu starker Durchfeuchtung mit entsprechenden Folgeschäden. Darüber hinaus kann trotz der möglichen Anpassung der Strahlwirkung an Untergrund und Anschmutzung eine Materialschädigung der zu reinigenden Oberfläche durch Abrasion nicht vollständig verhindert werden. Eine Alternative zu den genannten Reinigungsverfahren bietet die Plasmatechnologie. Wie im abgeschlossenen Forschungsprojekt gezeigt, können typische Fassadenmaterialien, wie Klinker, Sandstein, Feinsteinzeug, Marmor, Granit, Eloxal und Edelstahl mit kaltem Atmosphärendruckplasma gereinigt werden. Ein mobiles Abwasser- und chemikalienfreies Reinigungsverfahren, das zugleich materialschonend ist, wurde hiermit entwickelt. Als typische Anschmutzungen wurden Graffitianschmutzungen (Acryl- und Kunstharzlacke) und künstliche Atmosphärenschmutze eingesetzt. Die angeschmutzten Proben wurden einer definierten Bewitterung (abwechselnde UV- Bestrahlung und Betauung) für 30 Tage ausgesetzt. Zur Erzielung einer guten Reinigungswirkung mittels Plasma wurden verschiedene Prozessgase (Druckluft, Argon, Stickstoff) eingesetzt und Prozessparameter variiert, darunter Düsengeometrie, Abstand Düse-Substrat, Vorschubgeschwindigkeit und Anzahl der Überfahrten. Bei Anwendung von Druckluft als Prozessgas wurde unter Einsatz eines hochenergetischen Druckluft-Plasmastrahls unter bestimmten Verfahrensbedingungen ein effektiver Abtrag von schwarzem, grünem und rotem Acryl- und Kunstharzlack, aber auch von Algen und Pilzen von bis zu 100% erreicht. Weißer und silbernen Acryllack konnten hingegen nur zu maximal 70% entfernt werden. Die untersuchten Materialien wurde dabei sowohl mechanisch als auch thermisch nicht geschädigt. Während der Plasmabehandlung wurden relativ niedrige Oberflächentemperaturen von 60 bis 80°C für mineralische bzw. 70° bis 115°C für metallische Substrate gemessen usw
Objective: In a deregulated EU rail market monitoring of the vehicle and infrastructure interface is mandatory for enhanced availability of operation reducing costs. Especially when a rolling stock is crossing boundaries between independent infrastructure grids, cond ition monitoring becomes crucial. A monitoring tool on OCLs overhead contact lines - for infrastructure managers is needed for an separate measurement of contact force and surface condition of the vehicle current strip. The rolling stock operator needs a complementary device to measure not only the vertical contact force, but moreover the friction force, in order to analyse the vehicle and OCL interface condition. In SMITS a monitoring system for contact force on the interface current collector lt;- gt; c ontact wire has been developed. A sensor technology has been started to explore showing the potential for an extended range of rail monitoring tools. An innovative coherent sensor technology approach shall be investigated and two independent monitoring too ls for vehicle and infrastructure be developed. These shall be validated at new rail tracks specified for TSI interoperable cross boundary transportation: the Ltschberg Basis Tunnel, CH and the HSL Zuid high speed line, NL, both ready for operation in 2007 . Demonstration tests in operation will be performed along the Korridor X infrastructure passing through different countries rail networks. The outcome of the project will enable managers to specify driving conditions for the usage of their infrastructure to avoid excessive wear improving availability. Complementary rolling stock operators can monitor OCL condition giving them an informative argument in case of damage. Condition-dependent user fees as well as threat of penalty will force vehicle and infrast ructure managers to maintain the vehicle and infrastructure interface on a superior level of availability. The operational costs will be reduced and availability of transportation capacity enhanced.

In strict nature reserves and core zones of protected areas hunting and forestry operations are often restricted or banned. However, regarding the management of Wild boar, such hunt-free zones are discussed controversially and can lead to conflict. Hunters whose areas border no-hunting zones (and who have to reimburse farmers for crop damages caused by Wild boar) are concerned that the boars may evade effective population management by staying within the limits of the no-hunting zone, and farmers fear increased crop damage in the surroundings of such areas. Some conservationists are also concerned because Wild boars increasingly root protected habitats and can cause damage to rare plant assemblies. The three-year project Wild boar problem in the vicinity of protected areas by the Game Research Institute (Wildforschungsstelle) at the Centre for Agriculture Baden-Württemberg (LAZBW) aims at investigating if and how no-hunting zones might affect Wild boar activity, movement patterns, home range size, and habitat use, as well as crop damage caused by boars, by comparing these aspects between hunting-free zones and unprotected areas. Although there have already been a number of telemetry studies on Wild boar, including space use in the context of hunting activity, to date there is no study that has specifically investigated spatial and ecological aspects in and around protected areas. My dissertation Ecology of Wild boar Sus scrofa in the vicinity of protected areas is being carried out within the scope of the Game Research Institutes project and apart from the aims outlined above, further aspects of Wild boar ecology will be investigated, especially the role of Wild boar as bio-engineer and habitat creator for other species vs. unwanted damages at protected sites. Twenty-seven Vectronic GPS-GSM satellite collars with integrated activity sensors are available to tag Wild boars in three study areas: the non-protected Altdorfer Forest near Aulendorf with regular hunting activity and forestry, the nature reserve Wurzacher Ried with its ca. 700 ha core zone that is a strict reserve with no human activity, and the Biosphere Reserve Swabian Jura, especially in the surroundings of the former military training area near Münsingen and the 170 ha no-usage-area Föhrenberg.
Ziel des Projektes war die Erarbeitung eines Qualitätshandbuchs mit einheitlichen Standards zur Qualitätssicherung bei Dichtheitsprüfungen privater Abwasserleitungen. Als Grundlage wurden ausführliche Interviews mit 38 Städten und Gemeinden in NRW und 2 Städten in Hessen geführt und 214 Dichtheitsnachweise in verschiedenen Kommunen Nordrhein-Westfalens hinsichtlich ihrer Qualität ausgewertet. In den Interviews zeigten sich Unterschiede und Unsicherheiten bezüglich der möglichen Vorgaben zur Prüfmethode, zur Dokumentation und zur Vorlagepflicht sowie eine unterschiedliche Interpretation des Umgang mit Regenwasserleitungen im Mischsystem. Unsicherheiten bestehen auch bei der Kalkulation des Personalbedarfs und bei der Festlegung des Umfangs einer Prüfung von eingereichten Dichtheitsnachweisen. Bei der durchgeführten Qualitätsprüfung der Dichtheitsnachweise anhand eines erarbeiteten Bewertungskataloges stellte sich die Qualität der Prüfungen insgesamt als ausreichend bis zufrieden stellend dar, wobei die optischen Inspektionen etwas besser abschnitten. Verbesserungspotential besteht bei der Schadensansprache und bei der Art und Tiefe der Dokumentation der Prüfungen. Dies betrifft vor allem die Dokumentation untersuchter und auch nicht untersuchter Leitungsstränge und die digitale Aufzeichnung des Messverlaufs bei Prüfungen mit Wasser oder Luft. Unter Berücksichtigung der Ergebnisse der geprüften Dichtheitsnachweise werden technische Anforderungen an die Durchführung der Dichtheitsprüfung und an den Umfang und den Inhalt der im Rahmen der Dichtheitsprüfung zu erstellenden Unterlagen definiert. Darüber hinaus werden Kriterien für die Wahl der Prüfmethode anhand der Schutzziele Umwelt- und Gesundheitsschutz, Schutz der öffentlichen Abwasseranlage und Eigentumsschutz aufgezeigt. Eine Verbesserung der Qualität lässt sich vor allem durch eine systematische Kontrolle der Unterlagen durch die Kommunen erreichen. Für die verschiedenen Prüfumfänge wird der Bearbeitungsaufwand abgeschätzt, wobei über eine Kombination einer einfachen Plausibilitätsprüfung mit einer detaillierten inhaltlichen Prüfung, die stichprobenartig, aber systematisch durchgeführt wird, der Aufwand erheblich reduziert werden kann. Die Ergebnisse der Überprüfung sollten mit den Sachkundigen diskutiert und für eine weitere Nutzung standardisiert dokumentiert werden. Auf dieser Basis können auch Schulungsschwerpunkte ermittelt und Nichtempfehlungen oder Ausschlüsse ausgesprochen werden. Eine weitere Option sind Zusammenschlüsse.
