BACKGROUND: The Kingdom of Jordan belongs to the ten water scarcest countries in the world, and climate change is likely to increase the frequency of future droughts. Jordan is considered among the 10 most water impoverished countries in the world, with per capita water availability estimated at 170 m per annum, compared to an average of 1,000 m per annum in other countries. Jordan Government has taken the strategic decision to develop a conveyor system including a 325 km pipe to pump 100 million cubic meters per year of potable water from Disi-Mudawwara close to the Saudi Border in the south, to the Greater Amman area in the north. The construction of the water pipeline has started end of 2009 and shall be finished in 2013. Later on, the pipeline could serve as a major part of a national water carrier in order to convey desalinated water from the Red Sea to the economically most important central region of the country. The conveyor project will not only significantly increase water supplies to the capital, but also provide for the re-allocation of current supplies to other governorates, and for the conservation of aquifers. In the context of the Disi project that is co-funded by EIB two Environmental and Social Management Plans have been prepared: one for the private project partners and one for the Jordan Government. The latter includes the Governments obligation to re-balance water allocations to irrigation and to gradually restore the protected wetlands of Azraq (Ramsar site) east of Amman that has been depleted due to over-abstraction by re-directing discharge of highland aquifers after the Disi pipeline becomes operational. The Water Strategy recognizes that groundwater extraction for irrigation is beyond acceptable limits. Since the source is finite and priority should be given to human consumption it proposes to tackle the demand for irrigation through tariff adjustments, improved irrigation technology and disincentive to water intensive crops. The Disi aquifer is currently used for irrigation by farms producing all kinds of fruits and vegetables on a large scale and exporting most of their products to the Saudi and European markets and it is almost a third of Jordan's total consumption. The licenses for that commercial irrigation were finished by 2011/12. Whilst the licenses will be not renewed the difficulty will be the enforcement and satellite based information become an important supporting tool for monitoring. OUTLOOK: The ESA funded project Water management had the objective to support the South-North conveyor project and the activities of EIB together with the MWI in Jordan to ensure the supply of water for the increasing demand. EO Information provides a baseline for land cover and elevation and support the monitoring of further stages. usw.
SHAPE-RISK aims at optimising the efficiency of integrated risk management in the context of the sustainable development of the European process industry. The proposal addresses sustainable waste management and hazard reduction in production, storage and manufacturing. The main deliverable of the SHAPE-RISK process will be recommendations to design future cleaner and safer industrial systems. These recommendations will be discussed and endorsed by the Industry. And finally an agenda of actions, approved by Industry, will be done. The goal is to support life-cycle safety and minimisation of accident, pollution and emissions, from the producer of raw materials to the end-product delivered by the industrial installation. In operational terms, SHAPE-RISK aims at structuring a network with the organisations providing technical support to the Authorities in charge of the SEVESO II, IPPC and ATEX directives. This network organised in a Co-ordination Action will interact with the other stakeholders: Industry, the Public, representatives of Communities, International Organisation and NGOs. In 3 years, the result of SHAPE-RISK will be an integrated approach of the different components of risk management and the optimisation of the resources devoted to risk control (environment protection and accident prevention). It will be achieved by enhancing synergy between European, national and regional programmes, and also by taking into account the needs of the pre-accession countries. SHAPE-RISK will result in the dissemination of knowledge and in the specification of research activities to address innovative breakthrough that will serve the construction of safer and cleaner industrial systems. SHAPE-RISK then contributes to the integration and reinforcement of the European Research Area in risk prevention.
Ultra-High Performance Fibre Reinforced Concretes (UHPFRC) are characterised by a very low water/binder ratio, high binder content and an optimized fibrous reinforcement. These new building materials provide the structural engineer with an unique combination of extremely low permeability, high strength and tensile strain hardening behaviour in the range of ductile metals (up to 0.2 Prozent at localization) and excellent rheological properties in fresh state. Recent research works with UHPFRC have demonstrated that these materials were perfectly well suited and best adapted for applications in composite UHPFRC-concrete structures. All this however was established for UHPFRC made with pure Portland cements. The rapidly growing interest for the use of these materials for new constructions or improvement of existing structures has triggered major industrial efforts to provide optimized UHPFRC recipes (binders and fibrous mix) from locally available components. More specifically, the optimization of the binders (type and content) and fibrous mix in such recipes would dramatically facilitate the penetration of these products on the market. On another hand, it is well known that the use of blended cements with mineral additions presents significant advantages for usual concretes and more recent ones such as self-compacting concretes,. Among those industrial by-products, Ground Granulated Blast Furnace Slag (GGBFS) appears to be a promising solution for use in UHPFRC, for its widely spread availability and excellent properties in fresh state and at long term as hydraulic binder. The objective of this research is to study UHPFRC mixes with binders containing high dosages of GGBFS, and to determine an appropriate amount of cement replacement by slag which does not compromise the excellent properties of UHPFRC achieved actually with pure Portland cement (high early age strength, low drying shrinkage, moderate autogenous shrinkage, significant viscoelasticity, tensile hardening behaviour and self-healing capacity). The project will involve (1) experimental studies performed on materials at early age and long term (2) theoretical modelling and numerical simulations, for various kinds of UHPFRC recipes with or without blended cements. The results will be directly beneficial to end users in the form of recommendations for the industrial development of 'green' UHPFRC recipes with high amounts of cement replacement by GGBFS. As such, benefits can be expected at three levels: economical, with cheaper UHPFRC materials, ecological with significant reduction of the gas emissions associated with cementitious materials with a high cement dosage, and societal with the emergence of a new family of green Advanced Cementitious Materials, adapted for the improvement of existing structures, in order to reduce dramatically the burden of multiple interventions during their service life, in a sustainable way.
Nach den Kläranlagen tragen maschinentechnische Aggregate in den Sonderbauwerken der Abwasserableitung mit 10 - 15 Prozent einen erheblichen Anteil am Gesamtenergiebedarf der Abwasserentsorgung bei. Ob und durch welche Maßnahmen Einsparungspotenziale realisierbar sind, wurde im Rahmen des Vorhabens untersucht. Hier wurden - der Energiebedarf von Sonderbauwerke ermittelt, - mittels Variantenbetrachtung ein energieeffizienter Planungsansatz für Abwasserpumpwerke entworfen, - weitergehende Maßnahmen für einen energieeffizienten Betrieb von Sonderbauwerken in der Kanalisation aufgezeigt, - die Betriebssicherheit energetisch optimierter Pumpwerke mittels Sensitivitätsbetrachtungen überprüft und - die Vorgehensweise für eine energieoptimierte Planung in einem Pflichtenheft für Betriebs- und Energieeffizienzanalysen von Sonderbauwerken in der Siedlungsentwässerung zusammengefasst. Bei der Auswertung der Betriebsdaten zu den Energieverbräuchen von rd. 200 Pumpwerken ergaben sich Datendefizite. Bei nur einem Drittel der Pumpwerke standen Daten für eine Energieanalyse zur Verfügung. Der Energiebedarf der analysierten Pumpwerke betrug 4-15 Wattstunden je Kubikmeter und Meter Förderhohe (Wh/(m3 x m)). In Ausnahmefällen lagen die Energiebedarfswerte darüber. Im Vergleich benötigen effizient arbeitende Pumpwerken zwischen 4-6 Wh/(m3 x m). Bei der Energieoptimierung von Abwassersystemen gibt es im Wesentlichen vier bewährte Strategien, um den Energiebedarf zu reduzieren: - Senkung des Bedarfes an Transportenergie. - Einsatz effizienter Systeme. - Richtige Konzeption und Dimensionierung der Förderanlagen. - Lastabhängiger Betrieb mit Spitzenlastmanagement. Wie eine energetisch optimierte Planung sowie ein energetisch optimierter Betrieb zu gestalten ist, wurde mittels Variantenbetrachtung am Beispiel des Pumpwerks Gelsenkirchen-Polsum gezeigt. Für die Darstellung der Einsparungspotentiale sind die Bau und Betriebskosten in Relation zu den Energiekosten zu stellen. Werden die Energiekosten auf die gesamten Neu- oder Umbaukosten bezogen, nehmen die Energiekosten eine untergeordnete Rolle ein. Betrachtet man ausschließlich die elektrotechnischen Einbauten eines Pumpwerkes als Investitionskosten, lassen sich über den verminderten Energiebezug hohe Einsparungspotentiale aufzeigen. Eine intensive Energieanalyse von Pumpwerken und die daraus resultierenden Maßnahmen können eine Reduzierung des Energiebedarfes von rd. 20 Prozent erzielen. Dabei ist jede Anlage mit ihren spezifischen Randbedingungen zu betrachten. Die Sanierungsansätze können durch die Simulation des Pumpwerksbetriebes in einem Berechnungsmodell bewertet werden. Hierzu sind belastbare Betriebsdaten Voraussetzung. Die Durchführung eines Energiechecks ist ein erster Schritt hin zu einem energieeffizienten Betrieb von Abwasserpumpwerken.
The research projects of PMOD/WRC aim at understanding the terrestrial radiation budget and the influence of the Sun on the terrestrial climate. The latter is in the central focus of today's world-wide climate research and is termed 'Space Weather' if the emphasis is on short term events and it is termed 'Space Climate, if climate implications are investigated. From the point of view of the activities of PMOD/WRC, the most interesting aspect of research in solar physics is that the radiance output of the Sun itself is variable. The goal of solar physics research at PMOD/WRC is therefore, to advance our understanding of the origin of these variations in order to be able to reconstruct the solar influence on the climate in the past. The SNF grant supports: A) Interpretation of data from active space experiments: Presently, there are two active space experiments built by PMOD/WRC: VIRGO on SoHO since December 1995, which is still operational, and SOVIM on the ISS since February 2008; B) Preparing for the scientific exploitation of the upcoming space experiment LYRA/PROBA2 and PREMOS on PICRAD (with launch in 2009); C) Investigating the origin of the solar radiance variability in the UV by exploring the lower chromosphere with helioseismological methods. Since 1996 the space experiment VIRGO/SoHO is monitoring the Total (TSI) and spectral Solar Irradiance. The homogeneous VIRGO data provide a crucial element in the construction of the TSI composite and thus, VIRGO provides a key observation to investigate the influence of the Sun on the terrestrial climate. The PMOD/WRC is involved in three new space missions that continue the observations of total and spectral solar irradiance: SOVIM on the ISS since February 2008 and with launch in 2009 LYRA on PROBA2, and PREMOS on PICARD. SOVIM on the ISS continues to monitor total and spectral solar irradiance with instrumentation similar to VIRGO/SOHO. Together with the two other experiments SOLSPEC and SolACES on the same platform, which observe the spectral irradiance from the EUV to the near infrared, our knowledge of the spectral redistribution during TSI changes will be improved and provide a sound basis for understanding of solar irradiance variability. LYRA/PROBA2 observations will be used for a climate-chemistry model that was developed at PMOD/WRC as part of an ETH-funded Poly-project. When LYRA data become available we will use a special middle atmosphere version of this CCM model, SOCOL-I, for now-casting the state of the upper atmosphere as reaction to the UV irradiance as observed by LYRA/PROBA2. This now casting is primarily aimed at testing our understanding of the chemical and dynamical processes induced by the variable solar UV irradiance, but if successful, our now casting product is a welcome additional input for space weather applications. Until the launch of PROBA2, this subproject is aimed at preparing the computer model for its operational use.
Objective: The Wave Dragon is a slack-moored wave energy converter of the overtopping type. It is by far the most powerful wave energy converter and at the same time one of the most energy efficient and economic devices under development today. Since March 2003 a 20kW scale 1:4.5 prototype of a 7MW Wave Dragon has been tested as the world's first floating grid connected wave energy converter. The project will develop the Wave Dragon technology further from the tested all steel-built 20kW prototype to a full size composite built 7MW unit and by testing validate the technical and economic feasibility. The RTD-part of the project will: - Develop Wave Dragon's energy absorbing structure, the low head turbine power take-off system and the control systems. An additional reservoir placed above the existing reservoir level will also be developed. The result of these changes to the overall design will be a significant increase in power production and a reduction in O&M cost. The development of the 7MW unit will be based on the knowledge base established through the tests with the 20kW prototype and the design process will comprise several innovative elements utilizing the O&M experience from the 20kW prototype tests. - Develop cost effective construction methods and establish the optimal combination of in situ cast concrete, post- stressed reinforcement and pre-stressed concrete elements - Develop new supplementary environmental friendly water hydraulic power take-off systems - Demonstrate reliable and cost effective installation procedures and O&M schemes - Establish the necessary basis for design codes and recommendations for floating multi MW wave energy converters. The test program will demonstrate the availability, power production predictability, power production capability and medium to long term electricity generation costs at 0.052EUR/kWh in a wave climate of 24kW/m, which could be found relatively close to the cost at the major part of the Atlantic coast.
Flowering time is strongly regulated by the circadian clock, which drives photoperiodic flowering. We recently explored natural allelic diversity of the clock in the dicot Arabidopsis and found a 'memory' of the proceeding environment. Furthermore, we showed that clock variation has a large role in directing flowering time under field conditions. Cloning of one circadian quantitative trait locus revealed variation at the flowering-time gene EARLY FLOWERING 3 (ELF3). Here we will further explore allelic variation in clock genes to define key loci that direct photoperiodic flowering. Firstly, we will complete the construction of new Arabidopsis recombinant inbred populations derived from accessions originating from extremely differing latitudes, and map the genomes of these lines at kilobase resolution. These populations will be scored for variation in the clock and flowering time; dynamic correlations will be constructed. Together, components underling clock-gene variation that directs seasonal flowering will be identified. Secondly, we will examine the molecular genetics of circadian control of flowering in the monocot barley using existing and newly generated variation at barley ELF3. This gene is the likely direct regulator of the seasonality locus Ppd-H1. This second program should reveal dicot/monocot clock conservations and identify allelic variation at the circadian-clock gene ELF3 that could be directly used in barley breeding programs.
Sowohl die bisher gewonnenen Erkenntnisse und Erfahrungen mit Windkonvertern kleinerer und mittlerer Leistungen im In- und Ausland als auch die Ergebnisse mehrerer dem Projekt GROWIAN vorausgegangener FE-Vorhaben ließen erkennen, dass ein (großtechnischer Versuch zur additiven Erzeugung von elektrischem Strom aus Windenergie mit Leistungen zwischen 2000 und 3000 kW als realisierbar einzuschätzen war. So wurde folgerichtig der Entschluss gefasst, das Projekt GROWIAN in einer Prototypanlage zu verwirklichen, auch wenn mit der vorgegebenen Bemessung -Turmhöhe 100m/Rotor Durchmesser, 100m/Nennleistung 3000 kW- diese Größenordnung derzeit ohne Vorbild war, sodass in vielen Fällen technisches Neuland betreten werden musste. Zielsetzung: Die Projektierung, Konstruktion, Errichtung und Erprobung sollen zur Verwirklichung der Einzelentwicklung von (Anlagekomponenten und -systemen durchgeführt werden. Die damit gewonnenen Erkenntnisse sollen neben der Feststellung der Bauaufwendungen die Beurteilung der Realisierbarkeit und Wirtschaftlichkeit einer Stromerzeugung in großen Windenergieanlagen ermöglichen. Ergebnis: Ungeachtet der Frage der Lebensdauer und der festgestellten Bauaufwendungen hat die Anlage die in sie gesetzten Erwartungen voll erfüllt.
The aim of BioBuild is to use biocomposites to reduce the embodied energy in building facade, supporting structure and internal partition systems by at least 50Prozent over current materials with no increase in cost. This will lead to a step change in the use of sustainable, low carbon construction materials, by replacing aluminium, steel, FRP, brick and concrete in buildings. Facades are widely used in construction, primarily to protect and insulate the internal structure. Internal partitions are used to divide space, carry utilities and provide thermal and acoustic insulation. The current materials used such as aluminium, steel, brick and concrete are energy intensive to produce and have high embodied energy. FRP is an alternative construction material, benefitting from low weight, formability and simple manufacturing, allowing low material content structures and innovative design. However, typical resin and glass fibre are non-renewable, energy intensive to synthesise. Biocomposites overcome these drawbacks, whilst maintaining the benefits, being based on natural fibres and bioresins which have low embodied energy and cost. Biocomposites are renewable and sustainable resin and reinforcement structures. The resins in this project are furan and cashew nut oil based with reinforcing fibres of flax and jute. Bast fibres have lower environmental impacts than glass, concerning climate change and energy but have similar properties. Biocomposites are used commercially in automotive interior parts, but for outdoor applications they can degrade due to moisture absorption and bio-degradation. BioBuild will develop biocomposites and construction products with a life span of 40 years, by protecting the fibres with novel treatments and coatings. The result of the project will be a low cost, lightweight, durable and sustainable biocomposite building system, with full technical and environmental validation, offering low embodied energy construction materials.
