2. 1. Arterial mechanics : noninvasive identification of constitutive parameters and residual stress

   Author : Jonas Stålhand; Gerhard A. Holzapfel; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis concerns the mechanical modelling of arteries, and particularly a method to identify parameters describing the mechanical properties using only clinically obtainable in vivo measurements. The artery is modelled as a fibre reinforced, incompressible, thick-walled cylinder subjected to large deformations and a residual stress field. READ MORE

4. 2. Development of Methods to Investigate Pulmonary Arterial Smooth Muscle Cells under Hypoxia

   Author : Joel Wahl; Kerstin Ramser; Mikael Sjödahl; Fredrik Nikolajeff; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

   Abstract : Hypoxic pulmonary vasoconstriction (HPV) is a physiological response to localized alveolarhypoxia that is intrinsic to the pulmonary circulation. By hypoxia-induced contractionof pulmonary arterial smooth muscle cells (PASMCs), the pulmonary capillary bloodflow is redirected to alveolar areas of high oxygen partial pressure, thus maintaining theventilation-perfusion ratio.

5. 3. Computational model of abdominal aortic aneurysm inception and evolution

   Author : Andrii Grytsan; T. Christian Gasser; Nicholas Hill; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aneurysm; three dimensional; elastin degradation; growth; remodeling; fluid-solid-growth model; Teknisk mekanik; Engineering Mechanics;

   Abstract : Incidence of abdominal aortic aneurysm (AAA) is increasing in the aging society of the western world. Development of AAA is mostly asymptomatic and is characterized by a bulge in the abdominal aorta. However, AAA may suddenly rupture, which results in an internal bleeding associated with a high mortality rate. READ MORE

6. 4. Assessment of predicting blood flow and atherosclerosis in the aorta and renal arteries

   Author : Alexander Fuchs; Lisa Prahl Wittberg; Örjan Smedby; Chunliang Wang; Anders Persson; Elazer Edelman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blodflödessimulering; Åderförkalkning; Väggskjuvspänning; Blodrehologiska modeller; Engineering Mechanics; Teknisk mekanik;

   Abstract : Cardiovascular diseases (CVD) are the most common cause of death in large parts of the world. Atherosclerosis (AS) has a major part in most CVDs. AS is a slowly developingdisease which is dependent on multiple factors such as genetics and life style (food, smoking, and physical activities). READ MORE

7. 5. Turbulence Descriptors in Arterial Flows : Patient-Specific Computational Hemodynamics

   Author : Magnus Andersson; Matts Karlsson; Jonas Lantz; Tino Ebbers; Kristian Valen-Sendstad; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : At this very moment, there are literally millions of people who suffer from various types of cardiovascular diseases (CVDs), many of whom will experience reduced quality of life or premature lift expectancy. The detailed underlying pathogenic processes behind many of these disorders are not well understood, but were abnormal dynamics of the blood flow (hemodynamics) are believed to play an important role, especially atypical flow-mediated frictional forces on the intraluminal wall (i.
