  1. 1. Getting physical tangibles in a distributed virtual environment

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mattias Bergström; Luleå tekniska universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Funktionella produkter; Functional Product Development;

    Abstract : The design of products is an increasingly complex task, where companies do not have and do not want the in-house competence to manage the development of entire products. Consequently, companies outsource parts of product development projects to other companies or join in partnerships. READ MORE

  2. 2. Molecular associations and transport properties of amphiphiles and gastrointestinal mucin in aqueous solution

    University dissertation from Physical Chemistry 1, Lund University

    Author : Géraldine Lafitte; Lund University.; Lunds universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; transport properties; diffusion NMR; Magnetic resonance imaging; Physical chemistry; hydrophobic association; electrostatic repulsion; gel; Mucin; Surfactant;

    Abstract : An effective uptake/absorption of drug formulations involve many processes; one being the transport of the active molecule through the mucus layer. The mucus layer is a complex mixture of biological molecules. Among them, mucin is the molecule that mainly provides the gel properties of the layer. READ MORE

  3. 3. Neighborhood environment and physical activity

    University dissertation from Family medicine, cardiovascular epidemiology and lifestyle

    Author : Ulf Eriksson; Lund University.; Lunds universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; walkability; land use; residential density; physical activity pattern; accelerometer; public health; walking; GIS; physical activity; Neighborhood;

    Abstract : Introduction Insufficient levels of physical activity are one of the top contributors to global mortality, and it is an important public health priority to increase the proportion of physically active people in the population. The interest in environmental determinants of physical activity has been rapidly increasing over the past few years. READ MORE

  4. 4. Self-Assembly in Lipid-Protein Systems : Lung Surfactant, Stratum Corneum and Model Membranes

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Division of Physical Chemistry

    Author : Jenny Andersson; Lund University.; Lunds universitet.; [2018-01]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lipid self-assembly; lung surfactant; stratum corneum; dehydrin; cholesterol; osmolytes; urea; TMAO; ssNMR; cSAXS;

    Abstract : This thesis explores lipid self-assembly and aims to give a broad picture of self-assembly structures in simple and complex lipid-protein systems. The systems studied are lung surfactant, stratum corneum and simple model membranes. The lung surfactant mixture lines the alveolus in our lungs and stabilises the air- tissue interface. READ MORE

  5. 5. Structure, Dynamics and Phase Behaviour of Charged Soft Colloidal Dispersions

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Division of Physical Chemistry

    Author : Sofi Nöjd; Lund University.; Lunds universitet.; [2016-10]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microgels; directed self-assembly; interaction potentials; scattering methods; confocal laser scanning microscopy; dielectric spectroscopy;

    Abstract : Soft and deformable ionic microgels such as poly(N-isopropylacrylamide-co-acrylic acid), PNIPAM-co-AA, microgels have shown to be a versatile alternative to the already well-established hard sphere model systems. Their tuneable interaction potential makes them well suited as model systems to study the phase behaviour found for particles interacting via a soft isotropic potential. READ MORE
