  4. 2. The consequences of DNA lesions for mitochondrial DNA maintenance

    Author : Josefin M. E. Forslund; Sjoerd Wanrooij; Nasim Sabouri; Erik Johansson; Claes Gustafsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondria; mitochondrial DNA; DNA replication; DNA lesions; DNA polymerase γ; ribonucleotide incorporation; medicinsk biokemi; Medical Biochemistry;

    Abstract : Eukaryotic cells have their own energy-producing organelles called mitochondria. The energy is stored in the adenosine triphosphate (ATP) molecule and is produced via the oxidative phosphorylation process inside the mitochondria. Thirteen of the essential proteins required for this process are encoded on the mitochondrial DNA (mtDNA). READ MORE

  5. 3. The knowledge problem of public transport policy

    Author : Erik Johansson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public transport; Planning; Appraisal; Evaluation; Public transport; Planning; Appraisal; Evaluation;

    Abstract : The overall aim of the thesis is to investigate the knowledge problem in regional public transport planning. The knowledge problem is twofold. How do transport policy arrive at the desirable actions they take and how do they assess the alternatives, and what can we say about the contributions of already implemented transport schemes.

  6. 4. Simulations of Transport Phenomena and Porous Structures Using Dissipative Particle Dynamics

    Author : Erik Johansson; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The topic of this work is simulations of porous materials and transport phenomena at a mesoscopic length scale, i.e., a length scale larger than an individual atom but smaller than the continuum. The porous material studied is a membrane used in fuel cells. READ MORE

  7. 5. Computational studies of water vapour - Liquid equilibrium

    Author : Erik Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte Carlo simulation; cluster; water; Gibbs ensemble;

    Abstract : It is commonly known that water plays a crucial role in many natural and industrial processes. One of these processes is the formation of water trees, and the subsequent breakdown of polyethylene used for high voltage cable insulation purposes. READ MORE
