2. 1. Testing palaeomagnetic and 14C based geochronological methods in the Baltic Sea

   Author : Bryan Lougheed; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; coastal; geochronology; palaeomagnetic secular variation; PSV; radiocarbon; 14C; reservoir age; R t ; ΔR; salinity; δ18O; geomagnetic field; Holocene; deglacial; Fennoscandia.;

   Abstract : The Baltic Sea is a continental shelf sea that is influenced by both river runoff and marine water. The two water masses are vertically stratified in the Baltic Sea, resulting in a positive, estuarine circulation system, which has undergone changes in the past due to isostatic uplift of the Baltic basin.

   Abstract : Spin-torque transfer (STT) effects have brought spintronics ever closer to practical electronic applications, such as MRAM and active broadband microwave spin-torque oscillator (STO), and have emerged as an increasingly attractive field of research in spin dynamics. Utilizing materials with perpendicular magnetic anisotropy (PMA) in such applications offers several great advantages such as low-current, low-field operation combined with high thermal stability.

5. 3. Studies on the Epidemiology and Outcome of Primary Systemic Vasculitis

   Author : Aladdin Mohammad; Njurmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polyarteritis nodosa; survival; microscopic polyangiitis; arteritis; vasculitis damage index; Vasculitis; ANCA; Wegener s granulomatosis; Churg-Strauss syndrome;

   Abstract : Primary Systemic Vasculitides [PSV: Wegener's granulomatosis (WG), microscopic polyangiitis (MPA), Churg-Strauss syndrome (CSS) and polyarteritis nodosa (PAN)] are rare systemic diseases of unknown etiology; if untreated, they are associated with high morbidity and mortality rates. Changes in the classification and diagnostic improvements during the last decades have increased reported prevalence and incidence rates of PSV. READ MORE

6. 4. Cardiac Function and Aortic Valve Intervention : Echocardiographic Studies of Myocardial Recovery in Patients with Severe Aortic Valve Disease

   Author : Lena Forsberg; Eva Nylander; Éva Tamás; Odd Bech-Hanssen; Linköpings universitet; []
   Keywords : ;

   Abstract : In patients with severe aortic valve disease, aortic valve intervention is performed when the risk for mortality or morbidity with conservative management is significantly increased. Left ventricular (LV) longitudinal motion decreases before conventional echocardiographic measures such as ejection fraction, are influenced in patients with severe aortic valve disease. READ MORE

7. 5. Quantitative echocardiographic methods for patients with acute coronary syndrome

   Author : Carl Westholm; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Tissue Doppler;

   Abstract : Background: The aim of this thesis was to evaluate two diagnostic and two prognostic quantitative echocardiographic methods for patients with acute coronary syndrome (ACS). Methods:
Velocity tracking (VeT) presents the longitudinal tissue Doppler velocities of the left ventricle (LV) as a bull’s eye plot giving an easy three dimensional understanding of both the global and regional function of the LV in regard to longitudinal velocities, systolic as well as diastolic. READ MORE
