  2. 1. Tension and tradition : a study of late Iron Age spearheads around the Baltic Sea

    Author : Kristina Creutz; Bergljot Solberg; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Archaeology; Arkeologi; arkeologi; Archaeology;

    Abstract : This thesis discusses spearheads and individuals in Estonia, Latvia, eastern Sweden, Finland and western Russia during the 11th century. The source material consists of 335 spearheads of type M according to the typology of Petersen from 1919. READ MORE

  4. 2. A theory of experienced paradoxical tension in co-opetitive alliances

    Author : Tatbeeq Raza-Ullah; Maria Bengtsson; Malin Näsholm; Devi Gnyawali; Marianne Lewis; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; co-opetition; paradox; tension; cognitive difficulty; emotional ambivalence; management; balance; capability; performance; företagsekonomi; Business Studies;

    Abstract : Empirical research shows that co-opetition is a double-edged sword such that it can both help and hurt the achievement of desired performance outcomes. Despite the proliferation of co-opetitive alliances (i.e. READ MORE

  5. 3. Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses

    Author : Per-Johan Gustafsson; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cracking; corners; test-specimens; strength; tension; fracture mechanics; strain localization; size-effect; flexural strength; LEFM; fictitious crack model; Weibull; FEM; pipes; shear strength; concrete; diagonal tension;

    Abstract : Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. READ MORE

  6. 4. In-plane tension behaviour of masonry

    Author : Miklos Molnar; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; restrained shrinkage; cracking; movement joints; Building construction; mortar joints; KstrMasonry; masonry; in-plane tension; Byggnadsteknik; murverk; sprickor; krympning; dilatationsfogar;

    Abstract : The main purpose of the present work is to increase knowledge of in-plane tension behav-iour of masonry and develop a model able to describe the impact of parameters influencing cracking caused by restrained shrinkage. In the process the mechanism of load transfer between units and mortar joints is described. READ MORE

  7. 5. Baggy paper webs : Effect of uneven moisture and grammage profiles in different process steps

    Author : Cecilia Land; Lennart Stolpe; Kaarlo Niskanen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bagginess; drying; calendering; grammage; moisture content; paper; profile; reels; softwood kraft pulp; storage; strain; tension; web; Chemical Engineering; Kemiteknik;

    Abstract : One of the problems encountered in paper converting is caused by the occurrence of "baggy webs", which essentially is when the tension profile of the paper web is uneven. In an area with low tension the paper is longer, which results in bagginess. READ MORE
