1. Cardiac surgery and antiplatelet therapy
Abstract : Background Dual antiplatelet therapy (DAPT) with acetylsalicylic acid (ASA) and a P2Y12 inhibitor improves outcome in acute coronary syndrome (ACS). In the subset of ACS patients undergoing urgent cardiac surgery, ongoing or recently discontinued DAPT is associated with increased risk of bleeding. READ MORE

2. Spectral-element simulations of turbulent wall-bounded flows including transition and separation
Abstract : The spectral-element method (SEM) is used to study wall-bounded turbulent flowsin moderately complex geometries. The first part of the thesis is devoted to simulations of canonical flow cases, such as temporal K-type transitionand turbulent channel flow, to investigate general resolution requirements and computational efficiency of the numerical code nek5000.

3. Shear in Concrete Structural Elements Subjected to Dynamic Loads
Abstract : Concrete structural elements subjected to severe dynamic loads such as explosions at close range may cause shear failures. In the Oklahoma City bombing in 1995 two concrete columns on the ground level were reported to have failed in shear. READ MORE

4. Sampling from large flotation cells : An invastigation of spatial distribution
Abstract : The general trend in flotation technology today is towards larger flotation cells, which enables a higher throughput. However, adverse effects such as segregation and reduced froth transport efficiency have also been observed in larger cells. READ MORE

5. Microwave Frequency Stability and Spin Wave Mode Structure in Nano-Contact Spin Torque Oscillators
Abstract : The nano-contact spin torque oscillator (NC-STO) is an emerging device for highly tunable microwave frequency generation in the range from 0.1 GHz to above 65 GHz with an on-chip footprint on the scale of a few μm. READ MORE
