  2. 11. Input Calibration, Code Validation and Surrogate Model Development for Analysis of Two-phase Circulation Instability and Core Relocation Phenomena

    Author : Viet-Anh Phung; Pavel Kudinov; Cristophe Demaziere; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reactor system code; input calibration; code validation; surrogate model; two-phase circulation flow instability; in-vessel core relocation; genetic algorithm; artificial neural network; Reaktorsystemkod; indata kalibrering; kodvalidering; surrogatmodell; två-fas cirkulationsflöde; instabilitet; härdrelokering i reaktortanken; genetisk algoritm; artificiella neurala nätverk; Fysik; Physics;

    Abstract : Code validation and uncertainty quantification are important tasks in nuclear reactor safety analysis. Code users have to deal with large number of uncertain parameters, complex multi-physics, multi-dimensional and multi-scale phenomena. READ MORE

  4. 12. Clinical fluorescence cytometry : improvements to preparation methods and instrumentation

    Author : Thomas Heiden; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Fluorescence analysis; flow cytometry; image cytometry; DNA ploidy; proliferation; apoptosis; paraffin-embedded tissues; fresh tissues; S-phase fraction; debris; aggregates; spectral overlap; wavelength switching;

    Abstract : Fluorescence cytometry, which can be carried out by flow or image cytometry (FCM, ICM), provides a highly sensitive and specific tool for quantitative analysis of cell material. It is emerging from being a pure research method and becoming an important adjunct to clinical practice. To better realize its potential, more research is needed. READ MORE

  5. 13. Impact of Water-Level Variations on Slope Stability

    Author : Jens Johansson; Lars Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Waterfront-soil slopes are exposed to water-level fluctuations originating from either natural sources, e.g. extreme weather and tides, or from human activities such as watercourse regulation for irrigation, freshwater provision, hydropower production etc. READ MORE

  6. 14. Negative Pressure Wound Therapy. Therapy Settings and Biological Effects in Peripheral Wounds

    Author : Ola Borgquist; Lund Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Negative pressure wound therapy; vacuum-assisted closure; wound healing;

    Abstract : Negative pressure wound therapy (NPWT) promotes wound healing through several mechanisms, e.g., altered periwound blood flow, mechanical deformation of the wound edge tissue, and drainage of excess fluid and debris. READ MORE

  7. 15. Fast isolation of proteins from bioreactors using affinity chromatography techniques

    Author : Eva Pålsson; Avdelningen för klinisk genetik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chromatography; protein purification; analyses; dispersion; chromatography matrices; Biochemistry; Biokemi; Metabolism; expanded bed; metabolism; Biotechnology; Bioteknik;

    Abstract : The purification of proteins from raw materials like fermentation broth and other biological sources usually involves several purification steps and is rather time consuming and expensive. This is a major concern in the production of many important protein products e.g. pharmaceuticals such as insulin and blood coagulation factors. READ MORE
