  1. 1. Multiple twists in the molecular tales of YopD and LcrH in type III secretion by Yersinia pseudotuberculosis

    Författare :Petra J Edqvist; Matthew Francis; Olaf Schneewind; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yersinia pseudotuberculosis; T3SS; YopD; translocation process; LcrH; class II chaperone; substrate secretion pathway specificity; Molecular biology; Molekylärbiologi;

    Sammanfattning : The type III secretion system (T3SS) is a highly conserved secretion system among Gram negative bacteria that translocates anti-host proteins directly into the infected cells to overcome the host immune system and establish a bacterial infection. Yersinia pseudotuberculosis is one of three pathogenic Yersinia spp. LÄS MER

  3. 2. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion

    Författare :Jonny Nordström; Mark Lubberink; Jens Sörensen; Hendrik J Harms; Stephan Nekolla; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 15O-water; myocardial blood flow; cardiac remodeling; patient motion;

    Sammanfattning : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). LÄS MER

  4. 3. Aristotle on Contrariety as a Principle of First Philosophy

    Författare :Jens Tomas Anfindsen; Lilli Alanen; Eyjólfur Kjalar Emilsson; Dominic J. O'Meara; Uppsala universitet; []
    Nyckelord :Philosophy; Ancient philosophy; Aristotle; contrariety; privation; metaphysics; ontology; theology; cosmology; being and non-being.; Filosofi; idé- och lärdomshistoria; History Of Sciences and Ideas;

    Sammanfattning : This dissertation aims to reconstruct Aristotle’s theory of contrariety as a principle of first philosophy. According to Aristotle, any genus has one contrary opposition. It is the task of any science to study whatever contraries there are within the generic domain with which the science in question is concerned. LÄS MER

  5. 4. Averaging level control in the presence of frequent inlet flow upsets

    Författare :Peter Rosander; Alf J. Isaksson; Johan Löfberg; Morten Hovd; Linköpings universitet; []
    Nyckelord :Averaging level control; PI control; Surge tanks; Optimal control; Robust MPC; Process control;

    Sammanfattning : Buffer tanks are widely used within the process industry to prevent flow variations from being directly propagated throughout a plant. The capacity of the tank is used to smoothly transfer inlet flow upsets to the outlet. Ideally, the tank thus works as a low pass filter where the available tank capacity limits the achievable flow smoothing. LÄS MER

  7. 5. Improving Assessments of Hemodynamics and Vascular Disease

    Författare :Magnus Ziegler; Petter Dyverfeldt; Tino Ebbers; Jonas Lantz; Ebo de Muinck; Carljohan Carlhäll; Alex J. Barker; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Blood vessels are more than simple pipes, passively enabling blood to pass through them. Their form and function are dynamic, changing with both aging and disease. This process involves a feedback loop wherein changes to the shape of a blood vessel affect the hemodynamics, causing yet more structural adaptation. LÄS MER
