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

    Author : Sebastian Björklund; Fysikalisk kemi; []
    Keywords : 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

  5. 38. Greenhouse gas emission from tropical reservoirs : Spatial and temporal dynamics

    Author : Annika Linkhorst; Sebastian Sobek; Frédéric Guérin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; methane; carbon dioxide; climate; carbon cycle; lake; limnology; inland water;

    Abstract : The emission of methane (CH4) and carbon dioxide (CO2) from reservoirs has been estimated to make up for about 1.3% of the global anthropogenic greenhouse gas emission. The impoundment of a river leads to the accumulation of sediment that is brought in from inflowing rivers, and the sediment organic matter is degraded to CH4 and CO2. READ MORE

  6. 39. Multiscale X-ray Characterisation of Cellulose-based Solid Dispersions

    Author : Martina Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PXCT; WAXS; pharmaceutical formulations; multiscale characterisation; STXM; radiation damage; SAXS; X-ray imaging; solid dispersions; cellulose;

    Abstract : Cellulose-based solid dispersions are a promising formulation strategy for providing controlled drug release and dissolution enhancement of poorly soluble drugs. These dispersions can from structures on multiple length scales which can have both positive and negative effects on the functional properties of the formulation. READ MORE

  7. 40. Anaerobic Digestion of Solid Residues on the Bolivian Altiplano

    Author : Rene Alvarez; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; Altiplano; renewable energy; temperature fluctuation; low temperature; farm-scale digestion; manure; solid residues; Anaerobic Digestion; biogas;

    Abstract : Anaerobic digestion and the production of biogas can provide an efficient means of meeting energy needs locally and reducing organic loading due to untreated waste material in water recipients. Furthermore, residues after anaerobic digestion may be used as a fertilizer to improve the soil in many parts of the world. READ MORE
