This article studies differences in the results of using different risk estimation tools in the same hazardous situations involving dangerous machinery. We investigated how (a) types of risk estimation parameters and methods of constructing tools, (b) the number of levels of each parameter, and (c) the number of risk levels influence the results. Consequently, 31 risk estimation tools were compared by using them to estimate risk levels associated with 20 hazardous situations. Risk estimation appears to be tool-dependent, as different tools give different results with identical hazardous situations. The scope of the tool, its use, and construction could explain these differences. This article also proposes a series of rules for constructing tools to alleviate many problems associated with the variability of risk estimations.

Waste tyres are more and more widely used for geotechnical applications as backfill material that is either a substitute for natural soils or combined with them. Beyond the economical and environmental concern, these materials can help solving problems with low shear strength soils. This study aims at investigating a mechanical behaviour of tyre chip-sand mixtures thanks to a triaxial tests campaign. Two factors were studied: (i) the tyre chip content, from 0 to 100% by mass and (ii) the orientation of the pieces of tyre, with four varying orientation conditions. This paper focuses on the stress-strain behaviour of the different mixtures and their volumetric variation during the tests. The angle of friction and cohesion for each mixture are presented. The optimum percentage mass and optimum unit weight, which gives the maximum shear strength, are also determined. The influence of the different parameters is discussed.

The EU Pellucid project is developing an experience management system for public organizations with staff mobility. The paper presents an activity whitin the project focused on searching for information in repositories of documents. The project's background and the process of information searching are described. Ontological methods such as semantic annotation and similarity searching, as well as ontology- and full-text-based searching are presented. Monitoring of organizational repositories is discussed.
