  1. 1. Classical and Quantum Descriptions of Proteins, Lipids and Membranes

    Author : Richard Tjörnhammar; Olle Edholm; Sagar Pandit; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Quantum corrections; Coordination structure; Polarisation; Phase transitions; Kelvin differential equation; Line tension; Elastic membrane models; Molecular particle models; Zinc binding; Cholesterol and Phospholipids; Biologisk fysik; Biological Physics;

    Abstract : In this thesis the properties of proteins and membranes are studied by molecular dynamics simulations. The subject is decomposed into parts addressing free energy calculations in proteins, mechanical inclusion models for lipid bilayers, phase transitions and structural correlations in lipid bilayers and atomistic lipid bilayer models.

  2. 2. Dynamic Characteristics of Floating Breakwaters

    Author : Aurora Xiaomeng Lei; Chalmers University of Technology; []
    Keywords : floating breakwaters; couplings joints ; dynamic cables; dynamic response; line tension; wave attenuation; wave reflection;

    Abstract : The dynamic behaviour of interconnected floating breakwaters has been studied theoretically and experimentally. For this type of shore-protection system, problems that must be dealt with include wave loads on the breakwaters caused by the interaction between the bodies and the waves, motions of the moored breakwaters caused by the waves, changed wave fields in front of and behind the breakwaters, and forces on the mooring cables and in interconnections between breakwater units.

    Abstract : This thesis presents a novel approach to integrate chemical vapor deposition (CVD) graphene into silicon micro- and nanoelectromechanical systems (MEMS/NEMS) to fabricate different graphene based MEMS/NEMS structures and explore mechanical properties of graphene as well as their applications such as acceleration sensing, humidity sensing and CO2 sensing. The thesis also presents a novel method of characterization of CVD graphene grain boundary based defects. READ MORE

  4. 4. Responding Model Membranes. Lipid Phase Behaviour, Domain Formation and Permeability

    Author : Emma Sparr; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Water and solute flux; Gradients; Monolayer; Two-dimensional crystals; Line activiy; Osmotic stress; Interlamellar forces; Phospholipid-cholesterol interactions; Phase transitions; Bilayer stack; Stratum corneum; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis concerns the interplay between the lipid phase behaviour, domain formation and the permeability of bilayer membranes. An essential part of this work has been the understanding of the phase transitions and equilibrium properties of lipid bilayers. READ MORE

  5. 5. The Entheses of the Medial Meniscns and Ligaments of the Knee Joint : Descriptive and Experimental Studies

    Author : Jizong Gao; Michael Benjamin; Linköpings universitet; []
    Keywords : knee joint; meniscus; ligaments; insertion; enthesis; quantitative morphology; fibrocartilage; cement line; collagens; proteoglycans; nerve fibres; tensile strength; failure mode; transection; refixation; repair; healing; osteoarthrosis; histology; immunohistochemistry; biomechanics; rabbit model; MEDICINE; MEDICIN;

    Abstract : Meniscal injuries are common in sports. Surgical removal of the meniscus to relieve symptoms is associated with a high risk for late knee joint osteoarthrosis and pain. Meniscal repair or replacement has therefore been advocated. READ MORE
