  2. 11. On the local properties of compressible filter cakes

    Author : Tuve Mattsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local filtration properties; dead-end filtration; particle interactions; cake filtration; skin formation; constitutive relationships; modelling; solid-liquid separation;

    Abstract : Filtration as a means of separating solids from liquids is an important unit operation employed in a range of different industrial sectors, of which the forest products, mineral, chemical process and pharmaceutical industries are but a few. Accurate and applicable models for the filtration unit operation are imperative if industrial filtration equipment is to be designed correctly. READ MORE

  4. 12. Allergenic Oxidation Products from Fragrance Terpenes. Chemical Analysis and Determination of Sensitizing Potency

    Author : Johanna Rudbäck; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Autoxidation; Contact allergy; Essential oils; Fragrances; Hydroperoxides; Ionization techniques; Mass spectrometry; Prehapten; Sensitization; Skin; Structure-activity relationships; Terpenes;

    Abstract : The ubiquitous presence of fragrance compounds in consumer products has resulted in a high frequency of contact allergy to fragrances in the population. For prevention purposes and according to EU regulations, cosmetics must be labeled when containing the most prominent fragrance allergens in concentrations exceeding 0. READ MORE

  5. 13. Computational modeling of biological barriers

    Author : Christian Wennberg; Erik Lindahl; Thomas Cheatham; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; cholesterol; lipid bilayer; permeability; long-range interactions; Lennard-Jones; dispersion; particle-mesh Ewald; stratum corneum; skin formation; Biological Physics; Biologisk fysik;

    Abstract : One of the most important aspects for all life on this planet is the act to keep their biological processes in a state where they do not reach equilibrium. One part in the upholding of this imbalanced state is the barrier between the cells and their surroundings, created by the cell membrane. READ MORE

  6. 14. Steady-State Diffusion in Complex Amphiphilic Films

    Author : Christoffer Åberg; Fysikalisk kemi; []
    Keywords : 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

  7. 15. Experimental skin flaps and nitric oxide

    Author : Örjan Gribbe; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Surgical flaps; nitric oxide; ischemia; reperfusion; nitrite; laser Doppler; transit-time ultrasound flowmetry; electron microscopy; NO donors; NOS inhibitors;

    Abstract : Surgical flaps are used in plastic surgery to reconstruct tissue defects due to trauma or cancer removal. Occasionally flaps are subjected to ischemia and reperfusion injury leading to flap failure. READ MORE
