  1. 1. Genom symaskinens nålsöga : Teknik och social förändring i kvinnokultur och manskultur

    Författare :Louise Waldén; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Female Culture; Male Culture; Technological Culture; Sewing Machine; Huskvarna; Husqvarna; Husmodern; Insyn; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Second to firearms, the sewing machine is the first mechanical device to be manufactured on a large scale in factories. It is also the first industrial-technological appliance to be brought into the homes of all classes. The sewing machine has played an important role in industrial development and thereby in society.

  3. 2. Vertex Operators, String Vertices and Conformal Field Theory Deformations

    Författare :Per Sundell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conformal field theory; vertex operator; Riemann surface; supersymmetry; Reggeon; string theory; sewing;

    Sammanfattning : We compute multi-string interaction vertices by sewing of basic string interaction vertex operators, so called dual Reggeon vertex operators. These operators describe the interaction between two complete external string sectors. They are particularly useful when the interactions involve twisted sectors. LÄS MER

  4. 3. Skräddaren, sömmerskan och modet : Arbetsmetoder och arbetsdelning i tillverkningen av kvinnlig dräkt 1770-1830

    Författare :Pernilla Rasmussen; Margareta Nockert; Bo Lönnqvist; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Textile studies; dress history; object-based study; cultural history; fashion; tailor; seamstress; tailoring; manufacturing techniques; tailor’s books; cutting; sewing; division of labour; gender; guilds; the diaries of Årstafrun; Art; Konstvetenskap; Textile Studies; Textilvetenskap;

    Sammanfattning : The aim of this study in textile studies and cultural history is to gain a greater understanding of what happened to the division of labour and manufacturing techniques when female fashions changed in the period 1770-1830. This was a time of upheaval as regards fashions, and a change in dress practice. LÄS MER

  5. 4. Strings, Branes and Symmetries

    Författare :Anders Westerberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lie-algebra cohomology; Reggeon vertices; extended objects; string theory; p -branes; current algebra; supersymmetry; sewing; pseudodifferential operators; D-branes;

    Sammanfattning : Recent dramatic progress in the understanding of the non-perturbative structure of superstring theory shows that extended objects of various kinds, collectively referred to as p-branes, are an integral part of the theory. In this thesis, comprising an introductory text divided in two parts and seven appended research papers (Papers I-VII), we study various aspects of p-branes with relevance for superstring theory.
