  1. 1. Optimal damping and slow sound in ducts

    Författare :Zhe Zhang; Mats Åbom; Hans Bodén; Lars Enghardt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The thesis is dedicated to expanding knowledge on two duct acoustic issues including: 1) the optimal damping of low frequency sound and 2) the development and application of ‘slow sound’.To address the first issue, the ‘Cremer impedance’ proposed more than half a century ago has been revisited and further developed.

  3. 2. Enhancing membrane and secretory protein production yields in Escherichia coli

    Författare :Zhe Zhang; Jan-Willem de Gier; Claes von Wachenfeldt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; recombinant protein production; Escherichia coli; membrane protein; secretory protein; strain engineering; Biochemistry; biokemi;

    Sammanfattning : Proteins fulfill essential functions in living cells. To produce sufficient amounts of a protein is essential to study the structure and function of a protein, or to use it for medical purposes. Escherichia coli is a Gram-negative bacterium that is widely used for recombinant protein production. LÄS MER
