1. 21. Studies on novel interactors in human adipose tissue

   Författare :Amanda T Pettersson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Obesity is associated with a mild inflammation and altered protein secretion in adipose tissue. These changes have been suggested to contribute to the development of obesity-associated disorders including, insulin resistance, dyslipidemia, type 2 diabetes and cardiovascular disease. LÄS MER

3. 22. Nonlinear Isoviscous Behaviour of Compliant Journal Bearings

   Författare :Matthew Cha; Sergei Glavatskih; Ilmar Santos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compliant Journal Bearings;

   Sammanfattning : Plans to shut down nuclear power plants in some European countries as well as increased electricity production by wind and solar power will increase the work load on hydroelectric power plants in the future. Also, due to the power grid regulations, hydroelectric power plants undergo more frequent start-ups and shut-downs. LÄS MER

4. 23. Characterisation of human adipose tissue : ceramide metabolism, depot differences and evaluation of dysfunctionality

   Författare :Joanna Gertow; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Normal adipose tissue function is necessary for maintaining proper energy balance, as both excess and absence of this tissue lead to metabolic disturbances, such as insulin resistance. Adipose tissue can be dysfunctional in many ways, including disturbances in adipocyte size, lipolysis rate, adipokine secretion, inflammation, fibrosis or oxidative stress. LÄS MER

5. 24. Parameter Estimation in Linear Descriptor Systems

   Författare :Markus Gerdin; Linköpings universitet; []
   Nyckelord :differential-algebraic equations; descriptor systems; identification; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Linear descriptor systems form the natural way in which linear models of physical systems are delivered from an object-oriented modeling tool like Modelica. Linear descriptor systems are also known as linear differential-algebraic equations in the continuous-time case. LÄS MER

7. 25. Optimisation and Validation of Dynamic Susceptibility Contrast MRI Perfusion Measurements

   Författare :Linda Knutsson; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nukleärmedicin; radiobiologi; Nuclear medicine; radiobiology; radiologi; tomografi; medicinsk instrumentering; tomography; medical instrumentation; Clinical physics; cerebral blood volume; mean transit time; cerebral blood flow; perfusion; dynamic susceptibility contrast MRI arterial input function; Klinisk fysiologi; radiology;

   Sammanfattning : The studies presented in this thesis concern the optimisation and evaluation of the dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) technique for the assessment of perfusion-related parameters of the brain, such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT). Several methodological factors influence these measurements, for example, contrast-agent administration, arterial input function (AIF) registration, choice of deconvolution algorithm and the choice of pulse-sequence parameters.
