  2. 6. Physicochemical properties of root fiber suspensions. A comparison between parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius)

    Author : Alejandra Castro; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physicochemical properties; parsnip; yacon; plant suspensions; particle size distribution; rheology; fructans; dietary fiber;

    Abstract : The physicochemical properties of two root suspensions, parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius), were studied and compared at different concentrations and after being subjected to processes such as homogenization and heating. The study and the evaluation of the physicochemical properties of these plant materials in the form of pastes might help to increase the interest in these two roots, and possibly encourage their further industrial use.

  4. 7. WC grain growth during sintering of cemented carbides : Experiments and simulations

    Author : Karin Mannesson; John Ågren; Annika Borgenstam; Håkan Engqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cemented carbide; Grain growth; Abnormal grain growth; Image analysis; Modeling; 3-D grain size distribution; Inverse Saltykov; Materials science; Teknisk materialvetenskap;

    Abstract : Cemented carbides are composite materials consisting of a hard carbide and a ductile binder. They are powdermetallurgically manufactured, where liquid-phase sintering is one of the main steps. The most common cemented carbide consists of WC and Co and it is widely used for cutting tools.

  5. 8. Host-seeking activity of Ixodes ricinus in relation to the epidemiology of Lyme borreliosis in Sweden

    Author : Hans Mejlon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Borrelia burgdorferi; control; Ixodes ricinus; Lyme borreliosis; seasonality; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Entomology; entomologi;

    Abstract : This thesis examines seasonal, diel and vertical distribution patterns of activity of host-seeking Ixodes ricinus (L.) ticks at three localities in south-central Sweden. In addition, by examining the prevalence of infection in ticks with Lyme borreliosis (LB) spirochetes, Borrelia burgdorferi s. READ MORE

  6. 9. Nonionic Microemulsions: Dependence on Oil Chain Length of the Surfactant Curvature Elastic Properties

    Author : Joakim Balogh; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Light Scattering; NMR relaxation NMR self-diffusion; SANS contrast variation and contrast matched studies; saddle play modulus; made by C12E5; Nonionic microemulsion; balanced microemulsion; Fysikalisk kemi;

    Abstract : The aim with this thesis has been to increase the knowledge about nonionic microemulsions and how they behave with increasing temperature. I have studied Nonionic Microemulsions made from C12E5, water and oil, with predominally hexadecane as oil, but also with octane, decane, dodecane and tetradecane as oil. READ MORE

  7. 10. Characterization of particulate matter from atmospheric fluidized bed biomass gasifiers

    Author : Eva Gustafsson; Michael Strand; Marcus Öhman; Linnéuniversitetet; []
    Keywords : biomass gasification; fluidized bed; particulate matter; particle morphology; particle elementary composition; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : Through biomass gasification, biomass can be converted at high temperature to a product gas rich in carbon monoxide, hydrogen, and methane. After cleaning and upgrading, the product gas can be converted to biofuels such as hydrogen; methanol; dimethyl ether; and synthetic diesel, gasoline, and natural gas. READ MORE
