  2. 11. On Industrial Automation Software Components

    Author : Oscar Ljungkrantz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; IEC 61131; Programmable Logic Controller PLC ; IEC 61499; formal verification; Manufacturing automation software; software reusability; Reusable Automation Component RAC ; software specification;

    Abstract : This thesis deals with Programmable Logic Controller (PLC) programs in the manufacturing industry, that is to say programs that coordinate robots and machines. The last years there has been increased competition and shorter life-cycles of many mass-produced products. READ MORE

  4. 12. On Formal Specification and Verification of Function Block Applications in Industrial Control Logic Development

    Author : Oscar Ljungkrantz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; safety logic; function block; IEC 61131; software requirements and specification; formal verification; reusable automation component RAC ; temporal logic; manufacturing automation software; programmable logic controller PLC ; model checking;

    Abstract : Developing a control system for an automated manufacturing system is a challenging task. In addition to controlling and coordinating the machines and robots used in the production, the safety of the operators must be assured. READ MORE

  5. 13. Mechanisms of impaired insulin release in type-2 diabetes : studies in the GK rat model

    Author : Amel Guenifi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Goto-Kakizaki GK rat; Type-2 diabetes; insulin secretion; morphometry; adenylyl cyclase AC ; phospholipase-C PLC ; ß-cell;

    Abstract : Type-2 diabetes is a complex syndrome with a polygenic and multifactorial aetiology. It is characterised by its relatively late appearance in life and its mild progressive course. Glucose intolerance can generally be ascribed to disturbed pancreatic hormonal secretion and/or insulin resistance in the liver and extrahepatic tissues. READ MORE

  6. 14. Effects of Alzheimer's and Parkinson's disease gene mutation on cell signaling

    Author : Nodi Dehvari; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Alzheimer's disease (AD) and Parkinson's disease (PD) are the major neurodegenerative disorders affecting the elderly. The discovery of genes causing familial forms of these disorders has contributed enormously towards our understanding of underlying pathogenic mechanisms. READ MORE

  7. 15. Signalling to Activation of Cytosolic Phospholipase A2 and Arachidonate Release in Macrophages

    Author : Gösta Hiller; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal transduction; dexamethasone; macrophages; phospholipase C; phosphatidylinositol 3-kinase; mitogen-activated protein kinases; cytosolic phospholipase A2; arachidonic acid; Histology; cytochemistry; histokemi; cytokemi; tissue culture; Histologi; vävnadskultur; histochemistry;

    Abstract : Eicosanoids include prostaglandins, thromboxanes and leukotrienes, which are arachidonic acid oxygenation products. These lipids make important contributions to the signs and symptoms of inflammatory diseases. READ MORE
