  2. 1. Transition delay in boundary-layer flows via reactive control

    Author : Nicolò Fabbiane; Dan S. Henningson; Shervin Bagheri; Denis Sipp; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow control; drag reduction; net energy saving; adaptive control; model-based control; optimal control; flat-plate boundary layer; laminar-to- turbulent transition; plasma actuator; direct numerical simulation; in-flight experiments; strömningsstyrning; friktionsreduktion; netto energibesparing; adaptiv styrning; modellbaserad styrning; optimal kontroll; gränsskikt öve en plan platta; laminärt till turbulent omslag; plasma aktuator; DNS; flyg prov; Engineering Mechanics; Teknisk mekanik;

    Abstract : Transition delay in boundary-layer flows is achieved via reactive control of flow instabilities, i.e. Tollmien-Schlichting (TS) waves. Adaptive and model-based control techniques are investigated by means of direct numerical simulations (DNS) and experiments. READ MORE

  4. 2. Extraction and chromatography of bioactive compounds in complex samples using supercritical CO2 technology

    Author : Said Alhamimi; Centrum för analys och syntes; []
    Keywords : Supercritical CO2; Chromatography; Extraction; Mass transfer; Solubility;

    Abstract : Bioactive compounds found in plants have been of interest to man since ancient times. These compounds have the ability to modulate the metabolic processes in our bodies, which suggests that they may promote better health. Bioactive compounds vary in their chemical structure, polarity, stability and biological activity. READ MORE

  5. 3. Exploring the Possibilities of 14C Bomb-Pulse Dating of Human Tissue Samples

    Author : Elisavet Georgiadou; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 14C measurements; Bomb-pulse dating; human body; serum; plaque; Fysicumarkivet A:2014:Georgiadou;

    Abstract : The testing of nuclear weapons in the atmosphere, in the middle of the 20'h century, resulted in a bomb-pulse excess of atmospheric 14C. A bomb-pulse dating method was thus developed. The latter is a method to determine the time of formation of formerly living modern (i.e. READ MORE

  6. 4. Chemical labelling methods for gel free based proteomics

    Author : Åsa Wåhlander; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; 2D-HPLC; isotopes; labelling; proteomics; mass spectrometry;

    Abstract : In this thesis different aspects of gel free procedures for mass spectrometry based proteome analysis are addressed, with emphasis on labelling techniques. It is based on three original articles where the effects imposed onto peptides upon modification are investigated, and the development of a new type of labelling strategy is described. READ MORE

  7. 5. Particle concentrations : analysis methods for urban runoff

    Author : Kerstin Nordqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Urban runoff often contains high concentrations of particles. Pollutants that adsorbs to surfaces of particulate material will be transported to receiving waters or a sewage treatment plant. For the recipient, the particles in the runoff are a significant cause of water quality impairment. READ MORE
