  1. 1. Ambivalent solidaritet : Nation, migration och rasifiering i Svenska Kommunalarbetareförbundet 1972-2002

    Författare :Daniel Stridh; Paulina de los Reyes; Johan Svanberg; Silke Neunsinger; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Swedish Municipal Workers Union; Labour History; Migration; Welfare State; Racialization; National Identity; Racism; Integration; Kommunal; arbetarhistoria; migration; välfärdsstat; rasifiering; nationell identitet; rasism; integration; Economic History; ekonomisk historia;

    Sammanfattning : This thesis explores the historical relationship between the Swedish labour movement and the complex issues of migration, ethnic discrimination, and racism. More specifically, it analyses the way in which the Swedish Municipal Workers’ Union (Kommunal) understood, formulated, and problematized migration and racism between 1972 and 2002. LÄS MER

  4. 3. Sound, Light and Electricity : as applications and analysis techniques to study metabolic effect and biofilm characterization of Geobacter sulfurreducens

    Författare :Adolf Krige; Paul Christakopoulos; Ulrika Rova; Ashley Franks; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MFC; Microbial fuel cell; Raman microscopy; BES; Geobacter sulfurreducens; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : ElectricityBio-electrochemical systems such as microbial fuel cells (MFCs) and microbial electrolysis cells have shown promise in wastewater treatment, bioremediation, desalination, carbon sequestration and as an alternative, renewable energy source. MFCs produces electricity via anaerobic oxidation of substrates with the subsequent extracellular electron transfer to an electrode. LÄS MER

  5. 4. VCSEL Cavity Engineering for High Speed Modulation and Silicon Photonics Integration

    Författare :Emanuel Haglund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed modulation; on-chip laser source; vertical-cavity surface-emitting laser VCSEL ; semiconductor lasers; optical interconnects; large signal modulation; laser dynamics; heterogeneous integration; vertical-cavity silicon-integrated laser VCSIL ; silicon photonics;

    Sammanfattning : The GaAs-based vertical-cavity surface-emitting laser (VCSEL) is the standard light source in today's optical interconnects, due to its energy efficiency, low cost, and high speed already at low drive currents. The latest commercial VCSELs operate at data rates of up to 28 Gb/s, but it is expected that higher speeds will be required in the near future. LÄS MER

  7. 5. Return Migration from Sweden 1968-1996. A Longitudinal Analysis

    Författare :Martin Klinthäll; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; transient migration; longitudinal analysis; Sweden; income performance; integration; refugee; immigrant; Migration; labor market; self-selection; Social and economic history; Ekonomisk och social historia;

    Sammanfattning : This book deals with return migration from Sweden in the period 1968-1996 to Chile, Germany, Greece, Iran, Poland, Turkey, United States and Yugoslavia, against the background of economic and political developments in Sweden and in the different source countries. An important question in the study regards whether return migrants deviate from other immigrants in terms of human capital characteristics and economic integration. LÄS MER
