In the Bavarian Forest National Park a brief, but intense storm event on 1 August 1983 created large windfall areas. The windfall ecosystems within the protection zone of the park were left develop without interference; outside this zone windfall areas were cleared of dead wood but not afforested. A set of permanent plots (transect design with 10 to 10 m plots) was established in 1988 in spruce forests of wet and cool valley bottoms in order to document vegetation development. Resampling shall take place every five years; up to now it was done in 1993 and 1998. On cleared areas an initial raspberry (Rubus idaeus) shrub community was followed by pioneer birch (Betula pubescens, B. pendula) woodland, a sequence well known from managed forest stands. In contrast to this, these two stages were restricted to root plates of fallen trees in uncleared windfalls; here shade-tolerant tree species of the terminal forest stages established rather quickly from saplings that had already been present in the preceeding forest stand. Soil surface disturbances are identified to be causal to the management pathway of forest development, wereas the untouched pathway is caused by relatively low disturbance levels. The simulation model FORSKA-M is used to analyse different options of further stand development with a simulation time period of one hundred years.
Der schnelle Fortschritt der elektronischen Geräte erhöht die Nachfrage nach verbesserten Li-Ionen Batterien. Kommerziell erhältliche Li-Zellen nutzen meist Lithiumkobaltoxid für die positive Elektrode. Doch gerade dieses Material ist ein Hindernis für eine weitere Optimierung, insbesondere für eine Kostensenkung. Vor allem für größere Anwendungen wie Hybrid- oder Elektrofahrzeuge müssen alternative Materialen erforscht werden, die billiger, sicherer und umweltverträglicher sind. Daher wird im ISEA derzeit ein neues Forschungsprojekt ins Leben gerufen und die dafür benötigte Infrastruktur geschaffen. Die Forschung wird sich auf die Untersuchung geeigneter Übergangsmetalloxide und Polyanionen konzentrieren, die besonders gut zur Einlagerung von Li-Ionen geeignet sind. Es werden neue Herstellungsverfahren unter Verwendung wässriger Precurser-Substanzen untersucht, die Verbindungen mit überlegenen Eigenschaften erzeugen und außerdem leicht an eine Massenproduktion angepasst werden können. Ziel der Arbeiten ist, preisgünstiges Elektrodenmaterial zu entwickeln, das eine spezifische Energie von über 200 Wh/kg und eine Leistungsdichte von 400 W/kg aufweist. Außerdem werden Arbeiten im Bereich der physikalisch-chemischen Charakterisierung der neuen Materialien stattfinden sowie elektrochemische Analysen der gesamten Zellen- und Batteriesysteme durchgeführt. Das elektrodynamische Verhalten der neuen Zellen wird u. a. mit Hilfe der elektrochemischen Impedanzspektroskopie analysiert, um präzise und zuverlässige Algorithmen für ein späteres Batteriemonitoring im realen Betrieb zu finden.

Main The main objective of BIOSTRAT is to support the further development of a European Biodiversity Research Strategy. Such Research Strategy brings together ideas on research priorities in fundamental and applied sciences to address critical gaps in knowledge on the conservation and sustainable use of biodiversity. This Strategy is intended to support the decision-making process regarding biodiversity-related research at both the European scale and in individual EU Member States by linking existing structures. Rather than developing new structures BIOSTRAT will provide specific support to EPBRS (European Platform for Biodiversity Research Strategy), which provides a representative forum for researchers, science and environmental policy makers, and National Biodiversity Platforms. At the same time BIOSTRAT will ensure that other European and international efforts to develop research strategies in different fields of biodiversity research are linked to the development of a European Research Strategy through the EPBRS forum. BIOSTRAT will, therefore, support other international initiatives to link their efforts to the European Biodiversity Research Strategy. The overall objective will be achieved by: - Supporting the European Platform for Biodiversity Research Strategy (EPBRS) to develop and continually revise the EU Biodiversity Research Strategy - Including the results of existing and ongoing biodiversity research projects in the development of the EU Biodiversity Research Strategy. - Linking the EU Biodiversity Research Strategy to the national, European and international funding programmes, especially the ERA-Nets related to biodiversity issues - Incorporating GEOSS objectives in the EU Biodiversity Research Strategy - Linking EU Biodiversity Research Strategy with international initiatives including the multi-stakeholder consultative process of the Paris Conference, the Millennium Ecosystem assessment, the 2010 target, ESRI, GTI, GBIF, CBD, DIVERSITAS.
High current coated conductors (CC s) have high potential for developing electrical power applications and very high field magnets. The key issues for market success are low cost robust processes, high performance and a reliable manufacturing methodology of long length conductors. In recent years EU researchers and companies have made substantial progress towards these goals, based on vacuum (PLD) and chemical deposition (CSD) methods, towards nanostructuring of films. This provides a unique opportunity for Europe to integrate these advances in high performance conductors. The EUROTAPES project will address two broad objectives: 1/ the integration of the latest developments into simple conductor architectures for low and medium cost applications and to deliver +500m tapes. Defining of quality control tools and protocols to enhance the processing throughput and yield to achieve a pre-commercial cost target of 100 Euro/kAm. 2/ Use of advanced methodologies to enhance performance (larger thickness and Ic, enhanced pinning for high fields, reduction of ac losses, increased mechanical strength). Demonstration of high critical currents (Ic greater than 400A/cm-w, at 77K and self-field and Ic greater than 1000A/cm-w at 5K and 15T) and pinning forces (Fp greater than 100GN/m3 at 60 K). The CSD and PLD technologies will be combined to achieve optimized tape architectures, nanostructures and processes to address a variety of HTS applications at self-field, high and ultrahigh magnetic fields. Up to month 36, 3 types of conductors will be developed (RABiT, ABAD and round wire); at Mid Term 2 will be chosen for demonstration during the final 18 months.
The COMMON SENSE project will contribute to support the implementation of the Marine Strategy Framework Directive (MSFD) and other EU policies (e.g. Common Fisheries Policy), providing easily usable across several platforms, cost-effective, multi-functional innovative sensors to detect reliable in-situ measurements on key parameters by means of methodological standards. This proposal will focus, by means of a multidisciplinary and well-balanced consortium on eutrophication, contaminants, marine litter and underwater noise descriptors of the MSFD. This proposal will first provide a general understanding and integrated basis for sensors cost effective development (WP1 and WP2). Within the following WPs (5-8) the project will design and develop new generation sensors focused on the detection of: (1) nutrient analytes by utilising well-established colorimetric chemistries for phosphate, ammonia, nitrate and nitrite (2) low concentrations of heavy metals (Pb, Hg Cd, Zn and Cu), (3) surface concentration of microplastics (4) underwater noise by means of a bespoke acoustic sensor pod. These sensors, developed onto modular systems, will be integrated into multifunctional packages (WP4). Innovative transversal sensors (e.g. temperature, pressure, pH and pCO2) will be also integrated to provide the variables with a comprehensive reference frame. The Common Sensor Web Platform will be created (WP3) aiming at bringing a more sophisticated view of the environment implementing the sensor web enablement standards but optimising e.g. data acquisition, access and interoperability. The sensors developed will be interoperable with existing and new observing systems and they will also be field tested (WP9) by means of different platforms (e.g. research vessels, racing yachts, buoys). Dissemination and exploitation activities (WP10) will enable to transfer knowledge and technology resulting from the project to be used with commercial, scientific, conservational and strategic purposes.
