  1. 1. 3D property rights : an analysis of key factors based on international experience

    Author : Jenny Paulsson; Hans Mattsson; Jaap Zevenbergen; KTH; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; 3D property; property rights; condominium; apartment ownership; flat ownership; strata title; stratum; LAW JURISPRUDENCE; RÄTTSVETENSKAP JURIDIK;

    Abstract : The objectives of this thesis are to establish the fundamental principles in the field of 3D property rights by studying such systems in different countries with a particular focus on management questions, to systemize the acquired knowledge and demonstrate different ways of dealing with key factors essential to a well-functioning 3D property rights system. A theoretical background to the 3D property concept is given by presenting proposals as to a definition of 3D property and a classification of the primary forms of 3D property rights examined into specific types and categories, as well as an overview of international 3D property use.

  2. 2. Skin hydration - How water and osmolytes influence biophysical properties of stratum corneum

    Author : Sebastian Björklund; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Stratum corneum; diffusive transport; permeability; flow-through cell; Franz cell; transdermal drug delivery; water activity; vapor pressure; osmotic gradient; relative humidity; ceramide; free fatty acid; cholesterol; keratin filaments; natural moisturizing factor NMF ; urea; glycerol; molecular mobility; 13C natural-abundance solid-state NMR; polarization transfer; isothermal calorimetry; impedance spectroscopy; X-ray diffraction;

    Abstract : The outermost layer of skin (i.e., the stratum corneum, SC) is the interface that separates the water-rich inside of the body from the relatively dry external environment. SC forms an effective permeability barrier, which has to be overcome in transdermal drug delivery. READ MORE

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

    Author : Jenny Andersson; Fysikalisk kemi; []
    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

  4. 4. Foreign molecules in biomembranes : Molecular effects on intact stratum corneum and model lipid systems

    Author : Quoc Dat Pham; Fysikalisk kemi; []
    Keywords : stratum corneum; lipid; keratin filament; protein; DMPC; penetration enhancer; osmolyte; solvent; monoterpene; fatty acid; hydration; molecular mobility; fluidity; permeability; PT ssNMR; diffusion cell;

    Abstract : This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular information.

  5. 5. Steady-State Diffusion in Complex Amphiphilic Films

    Author : Christoffer Åberg; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; film formation; lung surfactant; skin surface pH; stratum corneum; responding membrane; diffusive transport; phase transition;

    Abstract : The relation between structure and diffusive transport at steady-state is investigated theoretically for amphiphilic systems. Amphiphilic systems typically show a large response to moderate changes in control parameters, such as temperature, osmotic pressure, and the presence of cosolvents and cosolutes. READ MORE
