  2. 11. Inactivation, Cell Injury and Growth of Microorganisms Exposed to Pulsed Electric Fields Using a Continuous Process

    Author : Kristina Aronsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Leuconostoc mesenteroides; PEF; Listeria innocua; cell injury; flow-through treatment chamber; membrane permeabilization; post-processing growth; microbial inactivation; pulsed electric fields; Escherichia coli; Saccharomyces cerevisiae;

    Abstract : Pulsed electric fields (PEF) is a proven technology to inactivate microorganisms under non-thermal conditions. The PEF technology has a potential as a "quality friendly" alternative to traditional methods of food preservation. READ MORE

  4. 12. Singing the body electric : Understanding the role of embodiment in performing and composing interactive music

    Author : Anna Einarsson; Tom Ziemke; Per Mårtenson; Sally-Jane Norman; Kungl. Musikhögskolan; []
    Keywords : HUMANIORA; HUMANITIES; music composition; embodiment; singing; interactive music; live electronics; affordances; performance technologies; computer music; music composition; embodiment; singing; interactive music; live electronics; affordances; performance technologies; ; computer music;

    Abstract : Almost since the birth of electronic music, composers have been fascinated by the prospect of integrating the human voice with its expressiveness and complexity into electronic musical works. This thesis addresses how performing with responsive technologies in mixed works, i.e. READ MORE

  5. 13. In-line application of electric fields in capillary separation systems

    Author : Björn Eriksson; Lars Blomberg; Magnus Andersson; Miroslav Macka; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary separation; conductivity; in-line; electric field assisted liquid chromatography; Analytical chemistry; Analytisk kemi; Kemi; Chemistry;

    Abstract : The magnitude of an electric field possible to apply in a capillary separation system is limited, because a high electric field causes a too high current through the capillary. Application of the electric field in-line will give an increased conductivity in the column, further increasing the risk of too high currents. READ MORE

  6. 14. Microwave Gas and Multipactor Breakdown in Inhomogeneous Fields

    Author : Joel Rasch; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; corona; inhomogeneous fields; multipactor; Microwave breakdown;

    Abstract : Microwave gas and multipactor breakdown remains to be one of the limiting factors for the maximum power in microwave devices. Above a certain electric field strength, the so-called breakdown threshold, free electrons can multiply by making ionizing impacts with neutral gas molecules, or causing secondary emission upon impact with system surfaces.

  7. 15. An Interactive Traction Motors Design and Selection Software

    Author : Hasan El Hinaoui-Hamze; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAD; Access; Electric Drives; Visual Basic; Internal Combustion Engines ICEs ; · Electric Motors EMs ; SQL; MATLAB; Hybrid Electric Vehicles HEVs ; Traction Motors; MagNet;

    Abstract : Use of electric motors in vehicle traction, in fact, predates the internal combustion engines (ICEs). Electric vehicles powered by dc motors were known as far back as 1890. Compared with vehicles powered by ICEs, the main drawback of the early electric vehicles was, and still is, their limited range and long recharging time. READ MORE
