  1. 1. Intra-industry trade: measurements, determinants and growth : a study of Swedish foreign trade

    Författare :Pär Hansson; Lars Lundberg; David Greenaway; Örebro universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intra-industry trade; determinants; comparative costs; factor intensity; product differentiation; elasticity of substitution; economies of scale; quasi-homothetictastes; Sweden; Economics; Nationalekonomi; intra-industry trade; quasi-homothetic tastes;

    Sammanfattning : The conclusions are that a traditional factor proportions model seems neither theoretically nor empirically to explaing IIT. However, a relaxation of the assumption of homogeneous products in an industry gives rise to several implications for IIT. LÄS MER

  2. 2. Ethyl Cellulose Membranes used in Modified Release Formulations

    Författare :Johan Hjärtstam; Chalmers University of Technology; []
    Nyckelord :osmotic pumping; water permeability; drug release; reflectivity; ethyl cellulose; degree of substitution; mechanical strength;

    Sammanfattning : Ethyl cellulose (EC) is a commonly used polymer in modified drug release formulations. The general aim of the present study was to investigate release mechanisms through non-porous EC membranes with hydroxypropyl methyl cellulose (HPMC) contents ranging from 0 to 30% by weight.

  3. 3. Utilization of Andean grain flours in the development of wheat flour dough

    Författare :Sander Jonathan Pérez Villarroel; Institutionen för livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; Wheat; Andean grains; Amaranth; Amaranthus caudatus; Canahua; Chenopodium pallidicaule; Quinoa; Chenopodium quinoa; Dough; Substitution; Ultracentrifugation; Phase separation; Dough composition; Macroscopic separation; Freezable water; Textural properties; Compression; Uniaxial tension; Biaxial tension; Principal component analysis; Partial least square regression; Bread;

    Sammanfattning : Bread dough was studied in relation to three Andean grain flours, quinoa (Chenopodium quinoa), amaranth (Amaranthus caudatus) and canahua (Chenopodium pallidicaule), as partial replacements for wheat flour with the perspectives of dough and breadmaking. This thesis deals with the understanding of both dough as a complex system, consisting of various water-filled polymers, and dough as a viscoelastic material, with different responses to deformations, in order to contribute to possibilities for improvements in dough analysis and development of novel products.
