Building Materials are a basic need, which is often difficult to meet in developing countries. Concrete is the building material best suited to meet these demands, although cement, the central ingredient is often disproportionately expensive in developing counties. The most promising option to lower costs (and environmental impact) is to blend conventional Portland cement with pozzolanic materials. The aim of this project is to develop technologies appropriate for the small scale, local production of pozzolans from clay (a material widely available) in conjunction with the exploitation of waste biomass for combined heat and power production. The modular concept of a clay activation unit, CAU to be coupled with a biomass boiler, will give the flexibility to adapt the solution to local conditions. We have already demonstrated that relatively common (low grade) clayey soils can be activated to give a pozzolan similar in performance to fly ash (from coal fired electricity production) widely used in the developed world. Results also indicate that it is possible to improve their reactivity by using and optimizing flash calcination, to allow high levels of substitution and very significant improvements in cost/performance ratio. To achieve this we need also to look at the performance of the activated clays in concrete from the point of view of rheology, hardening and durability to enable optimum cost/performance to be achieved according to local materials and applications. The partnership between LMC, EPFL and two academic groups in Cuba has already been established in a previous project. Furthermore, one of the Cuban partners plays a leading role in ECOSUR (a Swiss NGO) which has established workshops, producing low cost building materials, in many developing countries. In the first part of the project significant scientific advances were made, which enabled a huge acceleration in progress, relative to previous work by the Cuban partners alone. In addition, 3 Cuban PhD students spent several months working in the Swiss laboratory and have now returned to Cuba to continue their research. In this project, funding is requested for one PhD student to be based in Switzerland, who will work closely with 3 Cuban PhD Student (funded be the Cuban government). On the Cuban side, funds are requested for essential equipment and to fund the stays of the students at EPFL. Each of the Cuban students will spend 4-8 months working at EPFL during the course of the project.
The aim of CH-HALOMED is to install a measurement equipment to analyse halogenated greenhouse gases in the laboratory of Empa in addition to the continuously running identical system at Jungfraujoch (MEDUSA). This measurement equipment has been developeed by SIO in La Jolla (California) and is the main instrumentation used world-wide to perform state-of-the art measurements of halogenated greenhouse gases. The scientific goals of CH-HALOMED are to developing analytical methods for new halocarbons used in the industry and in consumer products and advance the sample trapping technology within the MEDUSA. Furthermore, the new system will allow sustaining the intercomparability within the European network: System for Observation of Halogenated Greenhouse Gases in Europe (SOGE) and its extension to China (SOGE-A) and linking of standards and scales at Jungfraujoch to those of AGAGE/NOAA. The instrumentation of CH-HALOMED will be used to analyse atmospheric halocarbons from international projects such as CARIBIC (air sampled by commercial aircrafts) and Antarctic samples by KOPRI (Korea Polar Research Institute) and NILU (Norwegian Institute for Air Research). Finally the MEDUSA system will be used for quantification of Swiss emissions of halogenated greenhouse gases by analysing air samples from the suburban station of Duebendorf (near Zurich). The context of CH-HALOMED is the global effort to assess the contribution of halogenated greenhouse gases to global warming. This is achieved by estimating global emissions of halogenated greenhouse gases (i.e. CFCs, HFCs, SF6) uisng their behaviour in the background air masses and to assess regional sources, using pollution events occuring at measurement sites in different continents. Furthermore, the MEDUSA system is extremely well-suited for detection of newly released industrial compounds in the atmosphere. The applicability of this concept has already been shown by Empa using existing equipments. With the new MEDUSA Empa has the possibility to advance in this field to faster reacting hydrofluorcarbons, which will be produced by industry in the next years. Although these compounds do have a minor influence on the global warming, their degradation products (i.e. fluorinated organic acids) could potentially affect aquatic bio-organisms.
Objective: PROMIT is the European Coordination Action (CA) for inter-modal freight transport initiating, facilitating and supporting the coordination and cooperation of national and European initiatives, projects, promotion centres, technology providers, research institutes and user groups related to this most complex transport form. The strategic PROMIT objective is to contribute to a faster improvement and implementation of inter-modal transport technologies and procedures and to help promoting inter-modal transport and mode shift by creating awareness on innovations, best practices and inter-modal transport opportunities for potential users as well as for politicians and for the research community. Due to the immense size of the inter-modality domain PROMIT has chosen a matrix organisation, where the domain expertise is treated in five parallel clusters: (1) Organisation and business models, (2) Inter-modal infrastructure and equipment, (3) Information and Communication Technologies, (4) Operation and services.
Objective: The HERCULES I.P. will develop new technologies to drastically reduce gaseous and particulate emissions from marine engines and concurrently increase engine efficiency and reliability, hence reduce specific fuel consumption, CO2 emissions and engine lifecy cle costs. Successive objectives for improvements to be available onboard ships are set for the years 2010 and 2020. These objectives will be attained through interrelated developments in thermodynamics and mechanics of 'extreme' parameter engines, advance d combustion concepts, multistage intelligent turbocharging, 'hot' engines with energy recovery and compounding, internal emission reduction methods and advanced aftertreatment techniques, new sensors for emissions and performance monitoring, adaptive cont rol for intelligent engines. Advanced process models and engineering software tools will be developed, to assist in component design. Prototype components will be manufactured and rig-tested. Engine experimental designs will be assessed on testbeds to vali date the new technologies and confirm the achieved objectives. Full-scale shipboard testing of chosen systems will demonstrate the potential benefits of next-generation marine engines. The work is structured in 9 Workpackages, with 18 Tasks and 54 Subproje cts. The Consortium includes engine makers, component suppliers and equipment manufacturers, compounded by renowned universities and research institutions, as well as, world-class shipping companies. The partners hold 80Prozent of the world market in marine engi nes and hence are the keepers of today's best-available-technology.'
Natural products remain an important source for drugs and a source of inspiration for medicinal chemists for the design of synthetic drugs and probes for the study of biological functions. The contribution of academic laboratories in natural products discovery has been substantial. The limiting factor of pharmaceutical natural product research has been with the tedious process of purification and identification of the lead molecules from the highly complex crude extract. Recent technological advances enable now a miniaturization of the screening and discovery process for natural product leads. The proposal here is for the purchase of a 500 MHz NMR spectrometer specifically equipped for the measurement of mass limited samples. It includes a recently commercialized 1 mm probe and autosampler and is capable of recording 1D and 2D NMR spectra with microgram (20-100 myg) amounts of natural products and synthetic drug-like molecules. The spectrometer is configured to fit into the technology platforms and the workflows of the Drug Screening Group of the Swiss Tropical Institute and the Institute of Pharmaceutical Biology. The instrument shall be used for various interdisciplinary projects of the two principal applicants and for a consortium which is being established. The major use will be for HPLC-based lead discovery in the area of Alzheimer's disease, Malaria, and neglected tropical diseases. The instrument will also be employed for metabolic fingerprinting of selected plants and phytomedicines. A third application will be in the analysis of compound libraries from external sources which are screened by the applicants in the context of the principal projects. An NMR instrument with this configuration is currently not in operation at a Swiss university. It is the missing link in a technology platform established at the laboratories of the two applicants. This platform should enable a paradigm shift in the way how natural product leads are identified, namely by miniaturizing the entire process of screening, separation and lead identification to the microgram level. A significant gain in efficiency of the discovery process and, thus, in research productivity, both qualitative and quantitative, is anticipated. The equipment will also be of interest to all those scientists in the biomedical sciences who need structural information from mass limited samples such as, for example drug metabolites.
Current climate research is challenged by questions on (i) the characteristics of natural climate variability, (ii) the discrimination from anthropogenic forcing, and (iii) ecological, societal and economic risks. Insight into regional climate change is critically important: Instrumental data and high resolution climate reconstructions show that regional climatic trends and extremes strongly exceed changes reported at hemispheric or global scales. Seasonal to annual, quantitative, regional multi-proxy climate reconstructions are fundamental to assess natural (i.e. pre-anthropogenic), forced and stochastic climate variability. Accurate reconstruction with quantified uncertainties of the 'baseline climate' is the precondition for evaluating the sensitivity of the Earth System to different forcing factors, and validating the results of global and regional, past and future climate modelling. In consequence, one of the hotspots of the international research agenda is to assess natural climate variability of the last 1000 years which encompass the 'Medieval Warm Period' and the 'Little Ice Age'. Among the most fundamental conclusions of recent work is the finding that the structure of past climate change in Europe is very different for each of the four seasons of the year. Most significant are deviations during fall, winter and spring, precisely during the seasons that are poorly or not recorded in natural climate archives. Thus new cold-season proxies are critically important and need to be explored. This is where our project and the new equipment come in. The innovation and novelty of our research is that, besides the classic lake-sediment proxies, Chrysophyte stomatocysts (microfossils produced by 'golden algae') are used for quantitative temperature reconstruction. Recent pioneering work has shown that stomatocysts in Alpine lakes are among the very few proxies and the only 'terrestrial' microfossils that allow quantitative winter/spring temperature reconstructions. This information is unique and has a great potential to evolve into the key parameter for cold-season climate reconstructions. Primary target archive for our research is Lake Silvaplana, a lake with 3500 years of varved sediments. High-quality analysis of stomatocysts requires scanning electron microscopy (acquisition of equipment subject to this proposal). International cutting-edge research calls for continuous, high resolution (annual) sampling. Consequently our research plan has two goals: (i) to optimize the efficiency of data collection with automated image acquisition and off-line image analysis, and (ii) to produce annual winter/spring temperature series for the last 1000 years.
A lysimeter is a vessel containing soil placed with its top edge to the ground surface. Lysimeter are used to study phases of the hydrological cycle in terms of water content and dynamics, e.g. infiltration, evapotranspiration or runoff. Lysimeter provide a good alternative to carry out and test various methods or theoretical theories under relative undisturbed circumstances. In cooperation with the Institute of Chemistry and Dynamics of the Geosphere, IV Agrosphere (ICG-IV) of the Forschungszentrum Jülich GmbH, the solute transport inside a lysimeter ought to be investigated.To avoid the inevitable problem of the boundary conditions for electromagnetic geophysical methods of a normal lysimeter with its metal wall, an alternative had to be found. Therefore PVC-cylinders were chosen with 1.5 m height and 1.2 m diameter. The dielectric permittivity of soils depends strongly on the water content. Therefore, GPR was used as it can provide non-invasive high-resolution information regarding the distribution of the dielectric permittivity of a heterogeneous medium. Because the used lysimeter has PVC walls tomographic measurements can be performed. Considering the relatively small dimensions of the lysimeter (1.2m diameter, 1.5m height) and the armament with sensors for other methods, a pair of shielded antennas was chosen with centre frequencies of approx. 750 MHz. In April and September 2002 first measurements were carried out on a filled but unequipped lysimeter to check signal quality, feasibility as well as the needed time to gather a dataset under ideal conditions. Furthermore pot irrigation tests were made in 2002 and 2004 to estimate the actual resolution with the available equipment. To derive the volumetric water content, the calculated dielectric permittivity values have to be transformed. Based on the soil inside the lysimeter (approx. 80% sand, 15% silt and 5% clay with approx. 40% porosity) appropriate mixing formulas for bulk dielectric permittivity have to be chosen and compared to the results gathered from alternative methods.

INFRES is a three year EU FP7 funded study focused on developing innovative technology and logistics for the forest residual biomass supply chain. The goal is to improve the overall competitiveness of forest residue biomass throughout the EU by accelerating technological (equipment and software) development and demonstrations. Following the directive for renewable energy targets in the EU, forest residue will continue to play an leading role in the renewable energy sector. This overall study focuses on the efficient collection, processing and delivery of woody feed stock for heating, power and emerging bio-refining uses. This research and demonstration project involves 23 partners, including nine research universities and organizations and 14 SMEs FELIS: FELIS will be leading Work Package 3, titled 'Business innovations and adaptations of forestry practices to bioenergy supply'. This research effort first evaluates the future customers and markets of forest biomass to 2050 and then focuses on how existing forestry practices may be modified in order to enhance and improve biomass recovery. Partnering with both software companies and regional bioenergy firms, this work task develops business and service innovations in order to improve organization efficiency, lowering cost and improving service.
Objective: The primary aim of the SIINN ERA-NET is to promote the rapid transfer of the results of nano-science and nanotechnology (N&N) research into industrial application by helping to create reliable conditions. In order to strengthen the European Research Area and to coordinate N&N-related R&D work, the project has the aim of bringing together a broad network of ministries, funding agencies, academic and industrial institutions to create a sustainable transnational programme of joint R&D in N&N. The commercial application of nano-materials (NMs) products is increasing rapidly, but one important question, the safety of NMs, still represents a barrier to their wide innovative use. Therefore the first priority of SIINN is to focus on developing a consolidated framework to address nano-related risks and the management of these risks for humans and the environment by investigating the toxicological behaviour of NMs. European R&D activities in N&N remain largely uncoordinated and fragmented, resulting in the sub-optimal use of available resources, such as human resources, research equipment and funding. Since available data on their toxicological behaviour is often scant, unreliable or contradictory, the SIINN Project will focus on ways of remedying this situation. After defining the criteria important for NM toxicology, the environmental health and safety (EHS) information currently available to Europe will be examined. Liaisons will strategically be established and maintained. They will network with organisations looking into the EHS of NMs within Europe and abroad with the aim of continually exchanging information with these. Available information will be examined for their reliability in respect of the assessment of the risks of NMs towards human health and to the environment and major knowledge gaps identified. At least two joint, transnational calls will be organised during the initial lifetime of SIINN in order to fill these gaps.
