  1. 1. Oxygen-reducing enzymes in coatings and films for active packaging

    Författare :Kristin Johansson; Lars Järnström; Caisa Johansson; Leif J. Jönsson; Jose M. Lagaron; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active packaging; food packaging; oxygen scavengers; oxygen-reducing enzymes; dispersion coating; biopolymers; Chemical Engineering; Kemiteknik;

    Sammanfattning : Oxygen scavengers are used in active packages to protect the food against deteriorative oxidation processes. The aim of this work was to investigate the possibilities to produce oxygen-scavenging packaging materials based on oxygen-reducing enzymes. LÄS MER

  3. 2. Studies of the relationship between aid and trade and the fiscal implications of emigration and HIV/AIDS interventions

    Författare :Lars M. Johansson; Harry Flam; Kjetil Storesletten; Björn Gustafson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi; Economics; nationalekonomi;

    Sammanfattning : This thesis consists of three studies; two on fiscal effects of demographic change and one on the correlation between international aid and trade flows.  Fiscal Implications of Emigration. This study examines the fiscal effects of emigration. A dynamic macroeconomic framework is used. LÄS MER

  4. 3. När man skär i nuet faller framtiden ut : Den globala krisens bildvärld i Sverige under 1970-talet

    Författare :Gustaf Johansson; Lars M. Andersson; Anders Ekström; Helge Jordheim; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Temporality; Visualization; The present; Global crisis; Environmentalism; 1970s; Media history;

    Sammanfattning : The aim of this dissertation is to investigate how this notion of a threatening global crisis was visualized in Swedish public media during the 1970s. The study has two main areas of interest. LÄS MER

  5. 4. Growth and Characterization of ZnO Nanocrystals

    Författare :Leif KE Ericsson; Kjell O Magnusson; Lars SO Johansson; Hanmin M Zhang; Omer Nour; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanocrystals; Surface physics; XPS; SEM; AES; AFM; STM; Physics; Fysik;

    Sammanfattning : The understanding of surfaces of materials is of crucial importance to all of us. Considering nanocrystals (NCs), that have a large surface to bulk ratio, the surfaces become even more important. Therefore, it is important to understand the fundamental surface properties in order to use NCs efficiently in applications. LÄS MER

  7. 5. Quality description in GPS precise point positioning

    Författare :Masoud Shirazian; Lars Erick Sjöberg; Jan M. Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; PPP;

    Sammanfattning : GPS processing, like every processing method for geodetic applications, relies upon least-squares estimation. Quality measures must be defined to assure that the estimates are close to reality. LÄS MER
