  1. 1. Barriers, drivers and context environment of technological innovation : An analysis of the biogas industry in Russia

    Författare :Tatiana Nevzorova; Vladimir Kutcherov; Emrah Karakaya; Enrico Cagno; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sustainability transitions; technological innovation system; context environment; driving forces and barriers; biogas; Russia.; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Sammanfattning : Global warming issues and the reduction of greenhouse gas emissions are high on many political agendas, and many scientists urge immediate changes to existing energy systems. In order to limit the drastic effects of climate change, complex solutions should be found that affect various sectors such as energy, agriculture, waste management, and transport. LÄS MER

  3. 2. Photosynthetic water oxidation : the function of two extrinsic proteins

    Författare :Tatiana Shutova; Göran Samuelsson; Stenbjörn Styring; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photosystem II; Psb0; Cah3; water oxidation; Plant physiology; Växtfysiologi;

    Sammanfattning : The solar energy accumulated by photosynthesis over billions of years is the sole source of energy available on Earth. Photosystem II (PSII) uses the sunlight to split water, an energetically unfavorable reaction where electrons and protons are extracted from water and oxygen is released as a by-product. LÄS MER

  4. 3. Carbon-based magnetic nanomaterials

    Författare :Valeria Zagaynova; Tatiana Makarova; Mauro Ricco; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon nanotube; fullerene; single molecular magnet; Mn12; graphite fluoride; nanoporous carbon; molecular magnetism; magnetic properties; SQUID magnetometry; x-ray diffraction; Raman spectroscopy; Materials Science; materialvetenskap;

    Sammanfattning : Magnetism of carbon-based materials is a challenging area for both fundamental research and possible applications. We present studies of low-dimensional carbon-based magnetic systems (fullerene-diluted molecular magnets, carbon nanotubes, graphite fluoride, and nanoporous carbon) by means of SQUID magnetometer, X-ray diffraction and vibrational spectroscopy, the latter techniques used as complementary instruments to find a correlation between the magnetic behaviour and the structure of the samples.

  5. 4. Free to Move Along : On the Urbanisation of Cross-border Mobility Controls - A Case of Roma 'EU migrants' in Malmö, Sweden

    Författare :Maria Persdotter; Listerborn Carina; Kirsten Simonsen; Ryan Powell; Per-Markku Ristilammi; Tatiana Fogelman; Malmö universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; migration; borders; urban governance; vulnerable EU citizens; eu migrants; squatting; racialisation; homelessness; eu citizenship;

    Sammanfattning : Den här avhandlingen – som jag valt att ge den svenska titeln Fri att röra sig, förvisad att röra sig: Rörlighetskontrollens urbanisering – Fallet med romska EU-medborgare i Malmö – behandlar den lokala politik som utvecklades i Malmö under åren 2014–2016 i förhållande till närvaron av så kallade utsatta EU-medborgare, och utvecklar ett teoretiskt resonemang om hur exkluderande gränser tar plats och blir till i städer. ”Utsatta EU-medborgare” är ett begrepp som används av svenska myndigheter för att beteckna medborgare från andra EU länder som vistas i Sverige utan en fast uppehållsrätt och som befinner sig i situationer präglade av extrem fattigdom och marginalisering.
