  2. 1. To Fold or To Fibrillate? Serendipity in Stability Studies

    Author : Olga Szczepankiewicz; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein stability; protein reconstitution; protein aggregation; Monellin; PGB1; Split-GFP; Amyloid beta;

    Abstract : Proteins are complex structures and years of research have been spent on attempts to understand their complexity. The non-covalent interactions involved in protein folding are: hydrophobic effect, electrostatic interactions, van der Waals interactions and hydrogen bonding. READ MORE

  4. 2. On the Growth of Bone through Stress Driven Diffusion and Bone Generation Processes

    Author : Gustav Lindberg; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone growth; Osteogenesis; Diffusion in bone; stress enhanced diffusion; Ginzburg-Landau; phase-field; diffusion experiment; Conductivity; Kalman filter; finite element method; Fourier series; Fick’s law; Osteology;

    Abstract : In order to prevent or modify bone degeneration due to rest or due to diseases such as osteopenia and osteoporosis, the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. READ MORE

  5. 3. Low-Power Nanowire Circuits and Transistors

    Author : Anil Dey; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis explores several novel material systems and innovative device concepts enabled by nanowire technology. State-of-the-art fabrication techniques such as electron beam lithography and atomic layer deposition are utilized to achieve high control and quality in the device fabrication. READ MORE

  6. 4. From Static Structures to Free Energy Landscapes: Characterizing Conformational Transitions in Biological Macromolecules

    Author : Cathrine Bergh; Erik Lindahl; Gerhard Hummer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein conformational transitions; molecular dynamics simulations; statistical mechanics; ion channels; Proteinkonformationsövergångar; molekyldynamiksimuleringar; statistisk mekanik; jonkanaler;

    Abstract : To be alive means to temporarily counteract the fundamental dispersive driving force described by the second law of thermodynamics, eventually leading all systems to decay and disorder. In cells, this task is partly carried out by proteins - small specialized molecular machines that utilize free energy to maintain the proper functioning of the cell. READ MORE

  7. 5. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction

    Author : Sasa Trajkovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VVA; Regenerative; Air-motor; Compressor; Pneumatic; Hybrid; Vehicle; Electric Hybrid; Drive Cycle; GT-Power; Simulink; FPGA;

    Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. READ MORE
