Two comp. polyester resins were modified by addn. of flame retardants (NH4 or melamine polyphosphates, melamine borate) and used for manufg. polymer-matrix glass mat-reinforced laminates. The laminates showed an Increased O Index and thermal decompn. temp. 300-700°C. The addn. of flame retardants resulted In a decrease of the total heat amounts generated during combustion but did not deteriorate the mech. properties of the laminates. Source
DESTRIERO - "A DEcision Support Tool for Reconstruction and recovery and for the IntEroperability of international Relief units in case Of complex crises situations, including CBRN contamination risks"
Agency: Cordis | Branch: FP7 | Program: CP-FP | Phase: SEC-2012.4.3-1 | Award Amount: 4.17M | Year: 2013
Today more people than ever are threatened by disasters, with no regards if natural or man-made. Furthermore, CBRN contamination risks can occur as a consequence of these events. Regions affected are wider and wider and reconstruction and recovery operations are longer-lasting, costly and complex, especially when decontamination is necessary. DESTRIERO aims at developing a next generation post-crisis needs assessment tool for reconstruction and recovery planning, including structural damage assessment through advanced remote sensing enriched by in-field data collection by mobile devices (buildings, bridges, dams) and related data integration and analysis, based on international standards, novel (automated) data and information interoperability across organisations and systems, in combination with an advanced multi-criteria decision analysis tool and methodology for multi-stakeholder information analyses, priority setting, decision making and recovery planning. Earth observation images will contribute to fast damage assessment and monitoring of the areas, together with data acquired by relief units on the field using novel smart-phone apps. Identified needs will be recorded, stored and made available to all organisations involved. Coordination and collaborative work at all levels of the organisations and among different ones will be possible through a network centric approach for the interoperability of information and service and the decision support tool. Critical infrastructure recovery will be considered with priority, as essential for the recovery of social and economic aspects (roads, bridges, schools, hospitals, plants, etc.), CBRN contamination and humanitarian aspects will be taken into consideration, as aggravating circumstances, while support to accountability of humanitarian aid contributions will be facilitated.

The management of crisis is one of the great challenges of the 21st century. The ever growing human, economic and environmental losses due to natural and man-made disasters evidence the need for a systematic approach to the management of crisis. A multi-disciplinary understanding and disaster risk management is required. In such situations, Collaborative Crisis Management (CCM) is usually coordinated by local authorities or dedicated civil protection organisations, supported by a variety of different national and international crisis management organisations, all acting relatively autonomously. The process is typically coordinated through periodic physical meetings of the involved organisations, in which information is shared about the situation, priorities are set and responsibilities allocated. Follow-up and execution of tasks is managed by each individual organisation, typically supported by a range of not interoperable information management tools, depending on the level of informatisation of the local or national crisis management systems. SECTOR aims at establishing the foundations of future Common CCM Information Spaces by expanding the European scientific knowledge base on (cross-border) multi-agency CCM processes and the complications these imply when aiming at setting-up and design cross-border supporting information Systems.

Pulsed thermography is a method of detection of thermal heterogeneity in layered structures. The temperature of an object excited by a pulse of energy varies depending on the thermal properties of each layer. It is possible to detect a thermal heterogeneity of the tested object on the basis of changes with time in the temperature of its surface. The values of temperature contrast between a reference area surface and a surface of area of the structure with a heterogeneity, obtained for successive moments of time, which vary depending on the type and depth of the heterogeneity. The method proposed by the authors consisted in determining the correlation coefficient of the temperature contrast function in the time domain obtained on the basis of thermographic measurements with the function obtained from modeling or from measurements of a well-known heterogeneity (examined with another method) in a similar structure. The resulting image is created from the correlation coefficients obtained for each pixel. This method enhances the detection of a thermal heterogeneity. © 2012 The Author(s). Source

Sanitary ceramic ware waste is classified as belonging to group of non-biodegradable industrial waste. The paper presents the studies on possible reuse ceramic sanitary wastes as the aggregate (both fine and coarse) in concrete. The procedure of aggregate production (crushing, dividing particles into two groups - fine and coarse particles and establishing their proportion) and designing the concrete mix are described. Studies on properties of this aggregate and properties of concrete containing this aggregate, are presented. Tested concrete displayed high strength and high abrasion resistance. This paper presents also results of examination of concrete with alumina cement and ceramic sanitary ware wastes as aggregate in 1000 C temperature. For comparison purposes, specimens with traditional natural aggregate and alumina cement were heated as well. As opposed to specimens of concrete with traditional aggregate, specimens with ceramic aggregate preserved their shape and cohesion and showed no cracks and defects. Despite some decrease in strength, these specimens after heating continued to display high compressive and tensile strength. On the basis of described studies, sanitary ceramic aggregate may be recommended for preparing special types of concrete: abrasion resistant concrete and concrete dedicated for members working in high temperatures. © 2013 Elsevier Ltd.
