    University dissertation from Jönköping : Jönköping University, School of Engineering

    Author : Kaveh Amouzgar; Högskolan i Jönköping.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-objective optimization; strength Pareto evolutionary algorithm; SPEA2; metamodel; surrogate model; response surface; radial basis functions; RBF;

    Abstract : As a result of the increase in accessibility of computational resources and the increase in the power of the computers during the last two decades, designers are able to create computer models to simulate the behavior of a complex products. To address global competitiveness, companies are forced to optimize their designs and products. READ MORE

  2. 2. The Role of Dopamine-Metabolising Enzymes in Renal Sodium Handling. An Experimental Study in vivo

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Cecilia Odlind; Uppsala universitet.; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; dopamine; kidney; sodium; MAO; COMT; rat; mice; RBF; oxygen; renal; L-dopa; DOPAC; entacapone; phenelzine; dopamine receptors; Fysiologi och anatomi; MEDICINE Physiology and pharmacology; MEDICIN Fysiologi och farmakologi; fysiologi; Physiology;

    Abstract : Dopamine (DA) has been shown to act as an intrarenal natriuretic hormone and defects in the renal DA system have been associated with some forms of hypertension. How the DA activity is upregulated durin- increased sodium intake is, however, unknown. READ MORE

  3. 3. Cardiac surgery and the kidney - studies on the effects of pharmacological interventions on renal perfusion, filtration and oxygenation

    University dissertation from Göteborg : University of Gothenburg

    Author : Gudrun Bragadottir; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney failure; acute; glomerular filtration rate; renal circulation; oxygen consumption; cardiac surgery; vasopressin; mannitol; levosimendan; estimating equations;

    Abstract : Acute kidney injury (AKI) commonly complicates cardiac surgery and is associated with high mortality. Renal ischemia is considered to be the major cause. There is a close association between glomerular filtration rate (GFR), tubular sodium reabsorption and renal oxygen consumption (RVO2) in humans. READ MORE

  4. 4. High Order Local Radial Basis Function Methods for Atmospheric Flow Simulations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Lehto; Uppsala universitet.; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radial basis function; meshless method; high order finite difference; atmospheric flow; hyper-viscosity; stable algorithm; Scientific Computing; Beräkningsvetenskap;

    Abstract : Since the introduction of modern computers, numerical methods for atmospheric simulations have routinely been applied for weather prediction, and in the last fifty years, there has been a steady improvement in the accuracy of forecasts. Accurate numerical models of the atmosphere are also becoming more important as researchers rely on global climate simulations to assess and understand the impact of global warming. READ MORE

  5. 5. Prevention and treatment of acute kidney injury after cardiac surgery

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Bengt Redfors; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney failure; acute glomerular filtration rate renal circulation oxygen consumption cardiac surgery mannitol dopamine norepinephrine autoregulation;

    Abstract : Acute kidney injury (AKI) occurs frequently after cardiac surgery and is independently associated with increased mortality. The main cause of AKI in these patients is renal ischemia. READ MORE
