1. 1. Afterload system design for functional donor heart assessment

   Författare :Harry Pigot; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physiological modelling; cardiac afterload; heart assessment; working heart; simulation; control of physiological and clinical variables;

   Sammanfattning : Heart transplantation is a life-saving procedure for patients with end-stage heart failure. However, conservative acceptance criteria result in most donated hearts being discarded. Enabling clinicians to assess heart function after organ procurement can pave the way for the safe use of hearts that are currently rejected. LÄS MER

   Sammanfattning : To stay competitive internationally, the Swedish forestry sector must increase its productivity by 2 to 3% annually. There are a variety of ways in which productivity can be increased. One option is to develop remote-controlled or unmanned machines, thus reducing the need for operator intervention. LÄS MER

5. 4. Ethanol from lignocellulose : physiological effects of inhibitors and fermentation strategies

   Författare :Mohammad J Taherzadeh; Chalmers Univ of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acetic acid; Agents; Cellulose; Enzyme inhibition; Feedback control; Fermentation; Hydrolysis; Metabolites; pH; Physiology; Wood; Yeast; Dilute acid hydrolyzate; Inhibitors; Lignocellulose; Physiological effects; Saccharomyces cerevisiae; Ethanol;

   Sammanfattning : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). LÄS MER

7. 5. Perioperative glucose control

   Författare :Christina Blixt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Trauma or surgery elicit a physiological stress response, which among others induces insulin resistance. It could be described as a state where the biological response to a given dose of insulin is reduced, and is associated with an altered glucose metabolism, as well as a disturbed lipid and protein metabolism and dysfunctional immune, inflammatory and coagulation systems.
