  1. 31. Towards Improved Control of TMP Refining Processes

    Författare :Karin Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; dynamic modeling; process limitations; simplified decoupling; Refiner; refining zone temperature; internal interconnections;

    Sammanfattning : The need for improved energy usage has become a key issue in all industrial sectors. In the energy demanding production of mechanical pulps many efforts havefocused on design development, but regarding control of refiners, there is still a potential for improvements. LÄS MER

  3. 32. Ecological disturbances and emergence of resistance in the oral and gastrointestinal microflora after drug exposure

    Författare :Christina Stark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ecology antimicrobial resistance oral gastrointestinal microflora B-lactamase enzyme induction.;

    Sammanfattning : The exposure of antimicrobial agents and antacids may disturb the ecological balance of the normal microflora. This influence often leads to decreased colonization resistance due to repression of sensitive bacteria and selection of resistant bacteria which have acquired resistance during therapy. LÄS MER

  4. 33. Mitochondrial dysfunction and alterations of brain HMPAO SPECT in depressive disorder : perspectives on origins of 'somatization'

    Författare :Ann Gardner; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :99mTc-d; 1-hexamethylpropyleneamine oxime; clinical rating scales; hearing loss; mtDNA; muscle biopsy; PCR; single photon emission computed tomography; tinnitus; unipolar depression.;

    Sammanfattning : A range of somatic symptoms are more common in patients with major depression than in the general population. Similar somatic symptoms and depression have been described in mitochondrial disorders, in which decreased production of adenosine triphosphate (ATP) is found. LÄS MER

  5. 34. Recent transitions in Ethiopian homegarden agroforestry : driving forces and changing gender relations

    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Homegarden agroforestry was a dominant land use practice in Southern Nations, Nationalities and People's Regional State (SNNPRS) Ethiopia until the 1990s. It has been known for its diversity, ecosystem balance and sustainability. LÄS MER

  7. 35. Cold Load Pick-up

    Författare :Evert Agneholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cold load pick-up; load modelling; field measurements; blackout; power system restoration;

    Sammanfattning : The load behaviour of the industrial and residential sector following different types of outages is dealt with in this dissertation. Data on the power consumption after these outages have been used for deriving models of the cold load pick-up. LÄS MER
