The issue of controlling the stability between colloidal particles in solution is important, at least for industrial applications, relying on efficient flocculation or stable dispersions. The objective of this thesis is to shed some light on fundamental mechanisms behind the interplay between attractive and repulsive forces, in solutions containing colloids and polymers. We approach the probl

Popular Abstract in Swedish Trä är ett konstruktionsmaterial med många positiva egenskaper, både avseende mekaniska och tekniska egenskaper och avseende det som ibland kallas mjuka egenskaper. Trä har generellt hög styrka i förhållande till sin vikt, det är ett naturligt förnybart material och det anses av många vara estetiskt tilltalande. Jämfört med andra vanliga konstruktionsmaterial som stål oThis thesis concerns experimental and theoretical work regarding perpendicular to grain fracture in wooden structural elements. The experimental part concerns strength tests of glulam beams with a hole. The theoretical parts concern development of two models for strength and fracture analysis, both based on fracture mechanics approaches, and their application to analysis of beams with a hole and d

Abstract Ulf Johansson Dahre Biotechnology and the Commodification of Human nature This paper discuss the human and social consequences of the technological development in the field of genetics. Leading biotechnologists argue that we are entering a world in which the human nature will be changed and cast in new design. The vision of a post-human society is growing. But what does it mean? By cha

The contribution of design is often regarded as providing a relieving service that delivers aesthetic competence at the end of a product development process. Previous studies have shown that industrial design consultancies aspire to be a strategic resource in their client firms, and that the focus of design is becoming increasingly intangible. The claim is that the competencies of the designer can

The paper discusses the general relation between sociology and literature and argues that the former has not only a lot in common with the latter, but also things to include and elaborate on. The paper uses as examples a number of sociologists and novelists and compares their ways of interpreting modern society and modern man.

This paper discuss the change in early design imposed by a Product-Service Systems (PSS) perspective onto the design and development phases of engineering design and how this affects the today de-facto standard of virtual modelling of product properties. The approach is exemplified via PSS situations related to aerospace and automotive industry in order to clarify “parameters of change” due to PSS

Popular Abstract in Swedish Konkurrensen har ökat markant under 2000-talet med ökad globalisering och hållbarhetstrender. Ständigt pågående teknologiska utvecklingar har medfört att kraven på rätt kvalitet på varor och tjänster har ökat. Tillverkare måste också följa skärpningar inom lagstiftning och krav på spårbarhet. Det har sammantaget lett till att det ställs allt hårdare krav på effektiv förToday’s trends are the ever growing competition with increased globalization and sustainability. Together with ongoing technological developments and the demand for right quality of products and services, this has also resulted in increased demands for legislation and traceability. This development has also had an impact on packaging and Packaging Logistics. This thesis deals with packaging, logis

Based on a case study from recent innovations in the Swedish white-collar union, Sif, this article introduces and develops the concept of membership interface unionism (MIU). The concept, it is argued, captures similar trends in trade unionism as that noted in the UK by Heery and Kelly in their concept of managerial unionism. Both these recent forms of unionism are signified by closer relations be
