THE COMMUNICATION HAVE-NOTS—Understanding communication control and “counter-publics” in contemporary China

This paper takes a new perspective on power and dominance in contemporary China by focusing on the Party-state’s control over communication. By looking at “counter-publics,” the voiceless in the Chinese public sphere, this paper investigates how the Party-state strengthens its controls over freedom of expression; deprives people of means of expression, interaction, and communication; and excludes

Probing Proton Translocation in Influenza A/M2 Proteoliposomes - A systematic Approach to Membrane-Protein Reconstitutions

Popular Abstract in Swedish Allt levande består av celler. Cellen är livets allra minsta byggsten. Cellen har ett hölje som kallas cellmembran. Detta membran skiljer cellens inre som kallas cytosol från omvärlden. I detta cellmembran sitter olika protein inbäddade. Genom dessa protein kommunicerar och utbyter cellen ämnen med sin omgivning. Många av dessa protein är mål för läkemedel och är därförAn improved method for reconstituting membrane proteins into artificial liposomes for quantitative functional analysis is presented. A number of key parameters for reconstitution by detergent removal are assessed in this thesis: The lipid-to-protein ratio, the detergent-to-lipid ratio and the lipid and cholesterol composition. New porphyrin-based pH-probes are evaluated. Based on this systematic,

ω-Transaminase Catalyzed Synthesis of Chiral Amines - Process Improvements Through Whole-cell Immobilization and in situ Product Removal

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Den här avhandlingen handlar om förbättringar aven process för att producera sk. kirala aminer -en typ av molekyler som ingår bl.a. i många läkemedel. Kirala molekyler är de som finns i två former, sk. enantiomerer, som är varandras spegelbild. Trots sina kemiska och fYsikaliska likheter kan de ha mycket olika biologisk effekt. Ett välThe industrial use of biocatalysts is increasingly important in the production of e.g. pharmaceuticals, chemicals, fuels and foodstuffs. A successful biocatalytic process is dependent on many factors, such as the biocatalyst properties, the nature of the reaction, reactor type and downstream processing. This work is focused on two important issues: Immobilization of the biocatalyst and in situ pro

Dissipation in Frequency Selective Structures

Dissipation in Frequency Selective Structures (FSS) of aperture/slot type is studied. The FSS consists of an arbitrary number of aperture layers and dielectric layers. An aperture layer consists of a conducting plate with a periodic array of apertures, with arbitrary cross-section. The dissipation in an FSS is due to losses in the dielectric material, and losses due to finite conductivity in the me
