The present proceedings are numbered Vols. 3 and 4 because they form an integral part of the entire series. It contains three overview papers on laboratory testing, in-situ testing, and characterisation of natural soil variability. Less well documented soil types such as organic clays and peats, loess, volcanic soils, residual soils, methane hydrate soils, and recent sediments are covered by fifteen papers. The remaining papers cover: alluvial and marine clays (6), highly fissured clays (1), boulder clay (1), silts (1), and natural soil variability (4). Following the tradition of the first workshop, authors were invited under consultation with the advisory committee chaired by Dr David Hight. The length and quality of the papers speak volumes on the tremendous dedication and efforts invested by all the invited authors. It is worth reiterating that the major part of the credit for this entire series belongs to the authors.

This new Recommended Practice (RP) gives guidance for modelling, analysis and prediction of environmental conditions as well guidance for calculating environmental loads acting on structures. The loads are limited to those due to wind, wave and current. The RP is based on state of the art within modelling and analysis of environmental conditions and loads and technical developments in recent R&D projects, as well as design experience from recent and ongoing projects .
The basic principles applied in this RP are in agreement with the most recognized rules and reflect industry practice and latest research.

Meshfree Methods for Partial Differential Equations V
Meshfree Methods for Partial Differential Equations V (Lecture Notes in Computational Science and Engineering)
By Michael Griebel, Marc Alexander Schweitzer
Publisher: Springer
Number Of Pages: 250
Publication Date: 2010-11-25
ISBN-10 / ASIN: 3642162282
ISBN-13 / EAN: 9783642162282
The numerical treatment of partial differential equations with particle methods and meshfree discretization techniques is an extremely active research field, both in the mathematics and engineering communities. Meshfree methods are becoming increasingly mainstream in various applications. Due to their independence of a mesh, particle schemes and meshfree methods can deal with large geometric changes of the domain more easily than classical discretization techniques. Furthermore, meshfree methods offer a promising approach for the coupling of particle models to continuous models. This volume of LNCSE is a collection of the papers from the proceedings of the Fifth International Workshop on Meshfree Methods, held in Bonn in August 2009. The articles address the different meshfree methods and their use in applied mathematics, physics and engineering. The volume is intended to foster this highly active and exciting area of interdisciplinary research and to present recent advances and findings in this field.

EN 15870:2009 Adhesives - Determination of tensile strength of butt joints (ISO 6922:1987 modified)
This European Standard specifies a method for determining the bond strength of a butt joint when subjected
to tensile force. The method can be applied to all types of adhesives. Although primarily intended for use
under ambient conditions, the basic method can also be applied to testing under a wide range of temperature
and other environmental conditions. The method requires rigid adherends that can be produced to the
required dimensional tolerances and that will withstand the forces applied to them during the test.
