  3. 2. Modelling of Bingham Suspensional Flow : Influence of Viscosity and Particle Properties Applicable to Cementitious Materials

    Författare :Annika Gram; Björn Lagerblad; Ulrich Diederichs; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-Compacting Concrete; SCC; Fresh concrete flow; Numerical simulation; Viscosity; Open channel flow;

    Sammanfattning : Simulation of fresh concrete flow has spurged with the advent of Self-Compacting Concrete, SCC. The fresh concrete rheology must be compatible with the reinforced formwork geometry to ensure complete and reliable form filling with smooth concrete surfaces. LÄS MER

  4. 3. A Solution Exchange Platform for Exposure of Cells to Chemical Waves

    Författare :Jessica Olofsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; waveform synthesis; solution exchange; cell signalling; patch clamp; receptor; high through-put; microfluidics; microfabrication; channel; chemical oscillations; ion channel; poly dimethylsiloxane ; drug discovery;

    Sammanfattning : This thesis presents the development, characterization and suggested applications of a platform for controlling the chemical environment around a cell or a cell constituent. The platform is unique in its capability to combine rapid solution switching with precise timing and access to a manifold of solution environments. LÄS MER

  5. 4. Surface tension-driven flow in soft porous materials — An investigation of the mechanism of capillary flow in microchannels of hydrogels

    Författare :Johanna Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting on soft materials; Capillary flow; alginate gel; capillary action;

    Sammanfattning : Spontaneous spreading of liquids in porous materials is of great industrial relevance and occurs in, for example, diapers, fabrics, paper or paint. Often, it is necessary to manipulate the spreading rate of liquids to result in the desired mass transport, for example to soak up large liquid volumes, as in a diaper. LÄS MER

  7. 5. Attraction channel as entrance to fishways

    Författare :Elianne Wassvik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The utilization of rivers for hydropower production leads to problems for fish migration. Migratory fish that swim upstream for reproduction need to overcome obstructions to reach their spawning grounds. On their way upstream they follow high water velocities. LÄS MER
