  1. 16. Diagnostic and prognostic value of cardiac magnetic resonance in patients with pulmonary hypertension

    Författare :Anthony Lindholm; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Pulmonary arterial hypertension (PAH) is a rare disease with poor prognosis. The symptoms are often unspecific, which can lead to delayed diagnosis. LÄS MER

  3. 17. Strain- and bioprocess-design strategies to increase production of (R)-3-hydroxybutyrate by Escherichia coli

    Författare :Mónica Guevara-Martínez; Gen Larsson; Antonius J. A. van Maris; Pau Ferrer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; E. coli; R -3-hydroxybutyrate; metabolic engineering; bioprocess design; NADPH; acetic acid; thioesterase; BAC; Bioteknologi; Biotechnology;

    Sammanfattning : Microbial bio-based processes have emerged as an alternative to replace fossil-based processes for the production of fuels and chemicals. (R)-3-hydroxybutyrate (3HB) is a medium-value chemical that has gained special attention as a precursor of antibiotics and vitamins, as a monomer for the synthesis of tailor-made polyesters and as a nutritional source for eukaryotic cells.

  4. 18. A TEM Investigation of Contact between Nanoparticles

    Författare :Yiming Yao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LACBED; CBED; nanoparticles; interface; adhesion; image simulation; energy filtering; misorientation; contacting; strain field TEM;

    Sammanfattning : Interaction between nanoparticles (1~100nm) provides us with answers to fundamental questions in many important applications e.g. adhesion, friction, and cold welding. The attractive force arises from the reduction of the total free surface and thus the total surface energy due to the formation of a boundary between the contacting particles. LÄS MER

  5. 19. On the Machinability of Ductile and Strain Hardening Materials - Models and Methods for Analyzing Machinability

    Författare :Fredrik Schultheiss; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Ti6Al4V; Duplex stainless steel; Machinability; Minimum chip thickness; Contact condition; Surface topography; Tool wear; Part cost; Sustainable machining; Polar diagram.;

    Sammanfattning : As quality and performance demands on today’s products increases, more and more advanced materials are being used during modern production. The problem is however that this in turn place new demands on the machining processes utilized. LÄS MER

  7. 20. Staphylococcus aureus toxins - Influence on food safety and animal health

    Författare :Yusak Budi Susilo; Teknisk mikrobiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Staphylococcus aureus; toxins; food safety; enterotoxin A SEA ; prophage life cycle; GFP reporter strain; flow cytometry; enterotoxin D SED ; accessory gene regulator agr ; bovine mastitis; enterotoxin C SEC ; toxic shock syndrome toxin-1 TSST-1 ;

    Sammanfattning : Staphylococcus aureus (S. aureus) is a notorious opportunistic foodborne pathogen and also a common cause of bovine mastitis. It is known to produce many different virulence factors, including various staphylococcal enterotoxins and toxic shock syndrome toxin-1 (TSST-1). LÄS MER
