    • Abstract The lipid composition of the erythrocyte membrane is said to be of importance for the rheological properties of the cell.  Methods: Fatty acid composition of phospholipids from the erythrocyte membrane was studied in 7 patients with type II diabetes when changing from tablets to insulin . Besides it was studied whether the composition of t h e membrane, especially the amount of w-3 fatty acids, influenced the filterability of the red cell. Fatty acid analyses were performed by a Varian 3700 Gas Chromatograph. Blood cell filterability was measured in theSt George'sFiltrometer.   Results: Patients with insufficiently controlled diabetes on oral agents, showed high amounts of fatty acids 16:0, 18:l and 20:4 compared t o the reference group. Increased amounts of 16:0, decreased amounts of 18:2, 20:4 and total PUFA (polyunsaturated fatty acids) were positively related to low RCTT (red cell transit time) when measured before insulin treatment. After insulin treatment only the correlation PUFA/RCTT remained. There were no corresponding findings in the reference group.   Conclusion: In poorly controlled type II diabetics the fatty acid composition of the red cell membrane is changed and saturated rather than unsaturated fatty acids, correlate with more filterable cells. Small differences of fatty acid composition i n membrane phospholipids do not influence blood cell rheology in healthy subjects.

  • Computerization of the Control Function in a Process Industry: A Case Study
  • 1993
  • Ingår i: Interacting with Computers: Preparing for he Nineties. ; , s. 251-257
  • Konferensbidrag (refereegranskat)abstract
    • Computerization of control room functions changes the work for the operators to a great extent. Their mental picture of the process, their possibilities to control the process for productivity and quality, the work content, the physical and the social working environment are examples of conditions which are changed one way or another. In order to be able to control the computerization process in an optimal way it is important to perform and to learn from case studies. In a Swedish paper pulp industry, where computerized control and information systems have been implemented and where operators have been involved in the computerization process, we have pursued an interview investigation. Twenty-eight operators and ten employees in other key positions have been asked e.g. about the control room design, the control system, the information system the effects of computerization on the work load and on the physical, mental and social working environment. Results from the interviews are presented and discussed. The control room design and the human-computer interfaces have been evaluated against guidelines and some of the results are discussed.
