    Abstract : In this work, the solubility of butyl paraben in 7 pure solvents and in 5 different ethanol-water mixtures has been determined from 1 ˚C to 50 ˚C. The solubility of ethyl paraben and propyl paraben in various solvents has been determined at 10 ˚C. READ MORE

  4. 17. Raster Image Analysis of Diffusion via Single Particle Methods

    Author : Marco Longfils; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; single particle tracking; raster scan; confocal laser scanning microscopy; image correlation spectroscopy; raster scan;

    Abstract : Soft biomaterials are widely used in many application areas, spanning from packaging materials to pharmaceuticals. To enhance their functionalities, understanding the interplay between microstructure and mass transport properties in these materials is fundamental. READ MORE

  5. 18. Studies of the fibre direction and local bending stiffness of Norway spruce timber : for application on machine strength grading

    Author : Min Hu; Marie Johansson; Mats Ekevad; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; digital image correlation; diving angle; fibre angle; grain angle; indicating property; laser scanning; modulus of elasticity; tracheid effect; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Machine strength grading is a production process in the sawmill industry used to grade sawn timber boards into different strength classes with specific characteristic values of the bending strength, modulus of elasticity (MOE) and density. These properties are called grade determining properties. READ MORE

  6. 19. Limiting conditions for a sustained flame over condensed fuels : Analysis by experiments and stagnant layer theory

    Author : Frida Vermina Plathner; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Critical mass flux; diffusion flame; extinction; sustained ignition; chemical heat of combustion; Convective heat transfer coefficient; external heat flux;

    Abstract : Ignition and extinction characteristics of a material determine whether a fire will be initiated and grow. In fire safety engineering, where modellers deal with a multitude of materials, simplified thresholds are commonly used to determine when ignition and extinction occur. READ MORE

  7. 20. Biophysical studies on aggregation processes and amyloid fibrils with focus on Alzheimer's disease

    Author : Niklas Bark; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Fluorescence correlation spectroscopy; amyloid fibril formation; Alzheimer s disease;

    Abstract : Alzheimer's disease (AD) is a fatal neurodegenerative disease, and is the most common form of dementia, affecting 1-2% of the population in industrialized countries. It is believed that intermediate species formed during amyloid Bpeptide (AB) polymerization play a key role in the pathogenesis of AD, but it is not known how such toxic effects are exerted. READ MORE
