  1. 21. Deactivation of Catalysts and Reaction Kinetics for Upgrading of Renewable Oils

    Författare :Prakhar Arora; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVO; Kinetic modeling; Catalyst deactivation; NiMo; Advanced biofuels; Catalyst; Hydrodeoxygenation;

    Sammanfattning : The transport sector is one of the main contributors of greenhouse gas emissions in the world. Advanced biofuels from renewable oils can play a decisive role in reducing carbon emissions from the transport sector. Advanced biofuels from waste streams like tall oil, used cooking oil etc. LÄS MER

  3. 22. Choice of bed material: a critical parameter in the optimization of dual fluidized bed systems

    Författare :Jelena Maric; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GoBiGas; biomass ash; ilmenite; feldspar; biofuel; alkali salts; Dual Fluidized Bed; bed material; Chemical Looping Reforming;

    Sammanfattning : Dual Fluidized Bed (DFB) gasification is a promising alternative method for the production of biofuels. In the DFB gasification process, the bed material, which is a crucial component of the process, has two possible roles: 1) to provide the heat needed for the gasification reaction; and 2) if it has catalytic properties, to improve the quality of the produced gas.

  4. 23. Redistribution of moisture and ions in cement based materials

    Författare :Magnus Åhs; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture redistribution; ion redistribution; cement based materials; hysteresis; sorption isotherm; scanning;

    Sammanfattning : There were two principal objectives for this thesis. The first was to develop a methodology and evaluation model of moisture redistribution in order to make the future relative humidity in a screeded concrete slab predictable. The second objective was to develop a method to determine the critical humidity for ion transport in concrete. LÄS MER

  5. 24. The Biophysics of Na+,K+-ATPase in neuronal health and disease

    Författare :Evgeny E. Akkuratov; Hjalmar Brismar; Anita Aperia; Stefan Wennmalm; Poul Nissen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Na ; K -ATPase; NMDA receptor; ouabain; phosphoproteome; oligomerization; rapid-onset dystonia-parkinsonism; Biologisk fysik; Biological Physics;

    Sammanfattning : Na+,K+-ATPase is one of the most important proteins in the mammalian cell. It creates sodium and potassium gradients which are fundamental for the membrane potential and sodium-dependent secondary active transport. LÄS MER

  7. 25. Imaging studies of cell physiology with particular reference to Na,K-ATPase function

    Författare :Ronnie M Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Na; K-ATPase; PKA; PKC; ouabain; cell attachment; Ca2 ; RVD; fluorescence lifetime;

    Sammanfattning : The membrane protein Na,K-ATPase is well known for its critical function of transporting sodium out of the cell and potassium into the cell, thereby creating a fundamental electrochemical gradient upon which several other important cell functions are dependent. In the current study we have investigated novel aspects of Na,K-ATPase function in cell physiology. LÄS MER
