This report presents the main results of a three-day RILEM Workshop held in Ravello, at Villa Rufolo, the European University
Centre for the Cultural Heritage, under the auspices of the Council of Europe and of the Italian National Research Council.
Considering the strong correspondence between research and industrial production evolved over the past years in the field
of conservation of works of art, the Workshop intended to focus attention on the two main problems of mortars: the study of
ancient mortars and the production of suitable mixtures for restoration, with a view to preparing a basic document useful
for further discussions and of proposing future RILEM action in the field of conservation of buildings of historical interest. 相似文献

ABSTRACTStrategic partnerships or strategic alliances have been called the “life blood” of companies in the new biotechnology industry, and a large number of firms are now participating in such collaborations. However, for a variety of reasons, not all such partnerships are successful. This paper describes some initial results from research conducted on a sample of small new biotechnology firms to identify the types and incidences of their strategic alliances, the reasons why they were formed, and the factors that contributed to their success or failure. Based on these preliminary findings, several recommendations are made for facilitating successful alliances in the new biotechnology and other industries. 相似文献

Disparate approaches to strategic environmental assessment (SEA) in New South Wales (NSW), Australia and Scotland are compared. The first is fragmented and unfamiliar while the other is well established. A detailed analysis of the use of SEA in each jurisdiction follows a contextual evaluation of its purpose. Whereas the Scottish system is supported by recent regulation and policy, both NSW and the overriding Commonwealth Government follow haphazard actions with few if any settled methodologies. In order to improve its environmental assessment credentials and promote more sustainable development outcomes, NSW might consider the need for SEA more seriously. Investigation of other systems, such as that in Scotland, may assist. 相似文献

A RILEM technical committee on Internal Sulfate Attack (TC 186-ISA) was established in 1996. In the ensuing years considerable
research was carried out, which helped to clarify the scientific knowledge surrounding this form of degradation. A Seminar
was organised in September 2002 to bring together the leading researchers in the field to debate the state of the advances
made in this area. All known active researchers in the area were invited and most were able to attend. The workshop was organised
with sessions designed to address the key questions related to Delayed Ettringite Formation (DEF) and Internal Sulfate Attack.
In each session one or more invited presentations and several shorter presentations were made by leading researchers to summarise
experimental findings and present their views. These presentations were followed by extensive discussion, at the end of which
a summary was made of the main points of agreement and of areas where questions remained open. This report gives these discussion
summaries as the current consensus view on this subject.
Editorial Note Created in 1996, the RILEM Technical Committee 186-ISA ‘Internal Sulfate Attack’ was chaired by Dr. Jan Skalny. The authors of this paper. Prof. Karen Scrivener, was the Secretary of RILEM TC 186-ISA. Following the Workshop in Villars, Switzerland, the RILEM TC 186-ISA was closed at the end of 2003. EPFL (Switzerland) is a RILEM Titular Member. Karen Scrivener is a RILEM Senior Member. She is the Convener of RILEM Cluster D, ‘Durability and Deterioration Mechanisms’ and she participates in RILEM TCs 197-NCM ‘Nanotechnology in construction materials’ and PAE ‘Performance of cement-based materials in aggressive aqueous environments’.

Ces présentations étaient suivies par de longues discussions, à la fin desquelles était fait un compterendu, résumant les principaux points d'accord et les domaines où des questions restaient en suspens. Dans ce rapport sont regroupés les résumés de ces discussions, résultats du consensus actuel sur ce thème.

Co-design represents an approach to the concurrent and collaborative design of systems. In an industrial context, firms adopt this approach to minimise risks/costs of new product development and to improve interactions along supply chains. For an industrial firm that delivers integrated product and service offerings i.e. an industrial product-service system (IPS2), co-design needs to be strategised in line with: (i) the IPS2 logic that challenges firms to improve the effectiveness and efficiency of operations and (ii) customer needs during life cycles. This article presents a multi-methodology-based study of the management of co-design within the context of an IPS2. It adopts a multi-case logic supplemented with key informant semi-structured interviews to capture implementations of co-design and how an IPS2 can be strategised to leverage the benefits of co-design. The article also highlights and discusses the resulting implications of the findings of the study for researchers and practitioners and potential future research directions. 相似文献

Round-robin analysis of the RILEM TC 162-TDF beam-bending test: Part 2—Approximation of δ from the CMOD response 总被引:1,自引:0,他引:1
B. I. G. Barr M. M. Lee E. J. de Place Hansen D. Dupont E. Erdem S. Schaerlaekens B. Schnütgen H. Stang L. Vandewalle 《Materials and Structures》2003,36(9):621-630
A round robin test programme was carried out using the beam-bending test recommended by RILEM TC 162-TDF [1]. The test programme included both plain and steel fibre reinforced concrete (SFRC) beams. A detailed analysis was carried out to investigate the influence of different test configurations on measurements of the crack mouth opening displacement (CMOD). Linear elastic fracture mechanics (LEFM) and non-linear fracture mechanics (NLFM) methods were utilised to investigate the problem analytically. From the analytical studies carried out, it is proposed that the CMOD should not be measured at a distance more than 5mm from the bottom fibre of the beam. A larger distance than 5mm will cause the deviation between the measured CMOD and the true CMOD to reach an unacceptable level. A simple rigid body model has been proposed to relate the CMOD to the mid-span deflection. The NLFM analysis and experimental results were compared for both the plain and SFRC beam results and it was found that results based on the basis of CMOD can be compared to those based on deflections, for practical purposes, using the simple rigid body model. The experimental results strongly suggest that the rigid body model could be effectively applied for all the types of materials tested in the round robin test programme. In addition it was found that the conversion from CMOD to the equivalent mid-span deflection, δc, revealed good agreement between the load-average mid-span deflection (P-δ) curve and the load-equivalent mid-span deflection (P-δ) curve especially for the SFRC specimens. It is proposed that the load-CMOD (P-CMOD) curve be used to calculate the proposed RILEM design parameters (as opposed to the P-δ curve) via the use of a correction factor determined using the simple rigid body model. 相似文献

System-oriented biological research (Systems Biology) is a vibrant field which aims to establish the higher-order principles behind complex multi-cellular processes. This classic theme of the Life Sciences was recently reinforced with a new armamentarium of high-throughput molecular tools. These omics approaches ('omes', greek for 'complete') allow us to now study biological behaviour in unprecedented width and detail. Consequently, Systems Biology is seen to bear the potential for major discoveries in the Life Sciences. 相似文献
