  1. 1. Fluid Power Pumps and the Electrification : With a Focus on Discrete Displacement Control in Load Handling Applications

    Författare :Samuel Kärnell; Liselott Ericson; Petter Krus; Maria Pettersson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : More and more vehicles are being electrified. Mobile working machines and heavy trucks are not excluded, and these machines are often hydraulically intense. Electrification entails new requirements for the hydraulic system and its components, and these requirements must be taken into consideration. LÄS MER

  2. 2. Hyaluronan and Renal Fluid Handling : Studies during Normal and Pathological Conditions of Renal Function

    Författare :Viktoria Göransson; Mats Rundgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; CD44; gerbils; hyaluronan; ischemia-reperfusion; kidney; osmolality; oxygen tension; rat; renomedullary interstitial cells; water; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Sammanfattning : The kidney is the major organ responsible for the regulation of the composition and volume of the body fluids, which is essential for homeostasis. The glycosaminoglycan hyaluronan (HA), with extreme water-binding capacity, is present in the interstitium of the kidney with a heterogenous distribution. LÄS MER

  3. 3. Regulation of Renal Hyaluronan in Water Handling : Studies in vivo and in vitro

    Författare :Sara Stridh; Peter Hansell; Mats Rundgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; water balance; fluid handling; diabetes; nephropathy; ACE fetopathy; reabsorption; hyaluronic acid; glycosaminoglycan; GAG; extracellular matrix; mTOR; rapamycin; streptozotocin;

    Sammanfattning : Hyaluronan (HA) is a negatively charged extracellular matrix (ECM) component with water-attracting properties. It is the dominating ECM component in the renal medullary interstitium, where the amount changes in relation to hydration status: it increases during hydration and decreases during dehydration.

  4. 4. Numerical study of flows related to aerated stirred tanks

    Författare :Dragana Arlov; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; fluiddynamik; Gaser; plasmas; fluid dynamics; Gases; Lattice Boltzmann method; Volume of Fluid; Aerated stirred tank; Large Eddy Simulation; Eulerian-Lagrangian model; Energy research; Energiforskning; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : The overall purpose with this work is to investigate the bubbly flow in a aerated stirred tank using numerical simulations. Aerated stirred tanks are commonly used in chemical processes for producing for example insulin and antibiotics. LÄS MER

  5. 5. Multiobjective optimization in engineering design : applications to fluid power systems

    Författare :Johan Andersson; Sören Andersson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis focuses on how to improve design and development of complex engineering systems by employing simulation and optimization techniques. Within the thesis, methods are developed and applied to systems that combine mechanical, hydraulical and electrical subsystems, so-called multi-domain systems. LÄS MER
