  1. 1. The Interaction between Triblock Copolymers and Surfactants in Dilute Aqueous Solution

    Author : Jörgen Jansson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; biopolymers; Polymerteknik; Physical chemistry; Fysikalisk kemi; Calorimetry; SAXS; DLS; SLS; Light scattering; Structure; Complex; Block copolymer-surfactant interaction; Block copolymer vesicles; Self-assembly; Triblock copolymers; NMR;

    Abstract : The solution properties of dilute aqueous solutions of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymers and their interaction with surfactants have been investigated using static and dynamic light scattering, combined with small angle X-ray scattering, calorimetry and nuclear magnetic resonance techniques. In aqueous solution, the triblock copolymers P123 and F127 (EO20PO68EO20 and EO97PO68EO97, respectively) form micelles with a PPO core and a PEO corona. READ MORE

  2. 2. Manufacturing Consensus : The Making of the Swedish Reformist Working Class

    Abstract : The 1910s were a precarious time for the labor movement. The Russian Revolution in 1917 sparked a trend towards radicalization among labor organizations and communist organizations spread all over Europe. These organizations challenged existing notions of the “worker,” causing an identity crisis in class organizations. READ MORE

  3. 3. The effect of flowing water on turbine rotor vibrations

    Author : Ida Jansson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : There is a lack of standardized rules on how the fluid in the turbine should be included in rotor models of hydraulic machinery. This thesis is an attempt to shed some light on this issue. We approach the problem from two viewpoints, situated at place at a hydropower plant and by mathematical analysis. READ MORE
