  2. 1. Analysis and Control of Continuous Microaerobic Ethanol Production by Yeast

    Author : Carl Johan Franzén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitrogen limitation; ethanol; Saccharomyces cerevisiae; glycerol; metabolic flux analysis; oxygen limitation; stoichiometric model; yeast physiology; RQ control;

    Abstract : Glucose fermentation by Saccharomyces cerevisiae, and xylose fermentation by Candida utilis and Pichia stipitis, were investigated under microaerobic conditions. A dynamic experimental method named oxygen programmed fermentation (OPF), and a method for microaerobic RQ control in continuous culture have been developed. READ MORE

  4. 2. Standardization and application of quantitative PCR methods in patients with hematological malignancies

    Author : Maria Malec; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Polymerase chain reaction; RQ-PCR; Minimal Residual Disease; Acute leukemia; Hodgkin s Lymphoma; cytokines;

    Abstract : Using modem combination chemotherapy regimens, it has been possible to increase the rate of complete remission (CR) in acute lymphoblastic (ALL) and acute myeloid leukemia (AML). The major reason for treatment failure in acute leukemia (AL) is the resistance of leukemic blasts to chemotherapeutic agents, which is accompanied by an inability of the immune system to eradicate residual leukemic cells surviving initial treatment.

  5. 3. Oil consumption and Friction in a Piston Ring-Cylinder Liner assembly.-A multifunctional Surface Approach

    Author : Cecilia Anderberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner surface; surface characterization; oil consumption; surface texture parameters;

    Abstract : About a half of the frictional losses in an internal combustion engine come from the interactions between the piston assembly and cylinder liner surface. The tribological considerations in the contact between the piston ring and cylinder liner have attracted much attention over the past few decades. READ MORE

  6. 4. Lund Concept for De-airing of the Left Heart. Clinical Evaluation

    Author : Maya Landenhed Smith; Thoraxkirurgi; []
    Keywords : open left heart surgery; de-airing; gaseous cerebral microemboli; transcranial Doppler sonography;

    Abstract : Background: Residual air accumulated air in the pulmonary veins constitutes a challenge to achievment of complete de-airing in open left heart surgery. To adress this problem, a conceptual method for de-airing was developed in Lund comprising bilateral opening of the pleurae to induce pulmonary collapse and a strategy with gradual pulmonary reperfusion and ventilation at weaning from cardiopulmonary bypass (CPB).
