  2. 1. Some Aspects on Macroscopic Mixing in a Tundish

    Author : Chao Chen; Anders Tilliander; Lage Jonsson; Pär Jönsson; Guoguang Cheng; Seppo Louhenkilpi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; continuous reactor; tundish; tracer; macroscopic mixing; water model; CFD; turbulence models; inclusions removal; inclusions deposition; dynamic removal; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Two aspects on macroscopic mixing in a continuous flow system – metallurgical tundish were studied. Specifically, 1) the first focus was on salt solution tracer mixing, which is important for tundish design from perspectives of tracer technology and Residence Time Distributions (RTD) as well as for the understanding of the macroscopic mixing in tundishes.

  4. 2. Multiscale Modeling of Molecular Sieving in LTA-type Zeolites : From the Quantum Level to the Macroscopic

    Author : Amber Mace; Laaksonen Aatto; Tina Düren; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CO2 separation; carbon capture; kinetic sieving; Zeolite A; Zeolite NaKA; cation exchange; temporal coarse graining; Kinetic Monte Carlo; Molecular Dynamics; AIMD; DFT; fysikalisk kemi; Physical Chemistry;

    Abstract : LTA-type zeolites with narrow window apertures coinciding with the approximate size of small gaseous molecules such as CO2 and N2 are interesting candidates for adsorbents with swing adsorption technologies due to their molecular sieving capabilities and otherwise attractive properties. These sieving capabilities are dependent on the energy barriers of diffusion between the zeolite pores, which can be fine-tuned by altering the framework composition. READ MORE

  5. 3. Modelling of macroscopic melt motion in fusion devices

    Author : Emil Thorén; Svetlana V. Ratynskaia; Panagiotis Tolias; Guy Matthews; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Magnetic confinement fusion is one of the most well developed methods envisioned to achieve thermonuclear fusion energy in the future. A central obstacle that remains in the way of safe and sustainable reactor operation is the interaction that occurs between the plasma and vessel wall components. READ MORE

  6. 4. Macroscopic models of Chinese hamster ovary cell cultures

    Author : Erika Hagrot; Véronique Chotteau; Anders Forsgren; Nathan E. Lewis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chinese hamster ovary; Amino acid; Metabolic network; Metabolic flux analysis; Kinetic modeling; Elementary flux mode; Optimization; Column generation; Bioteknologi; Biotechnology;

    Abstract : Biopharmaceuticals treat a range of diseases, and is a growing sector within the pharmaceutical industry. A majority of these complex molecules are produced by genetically modified mammalian cells in large-scale cell cultures. READ MORE

  7. 5. Internal dosimetry. Macroscopic, small-scale and microscopic perspectives

    Author : Cecilia Hindorf; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Nukleärmedicin; radiobiology; Nuclear medicine; B-cell lymphoma; Radioimmunotherapy; Radionuclide therapy; Internal dosimetry; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

    Abstract : Internal dosimetry deals with the assessment of absorbed dose for radionuclides distributed inside the body. The absorbed dose is in its turn used for correlation with the biological effect caused by the irradiation. READ MORE
