1. Treatment of Right Ventricular Failure through Partial Volume Exclusion : An Experimental Study
Abstract : Implantation of a left ventricular assist device (LVAD) is a potential treatment in terminal heart failure. Right ventricular (RV) failure is a severe complication in these patients and sometimes requires additional placement of a right ventricular assist device (RVAD). READ MORE

2. fMRI for mapping the plastic somatotopy of primary somatosensory cortex - Development and clinical applications
Abstract : Functional magnetic resonance imaging (fMRI) is a widely used tool for studying brain function in vivo. The technique is based on acquiring brain images sensitive to the physiological response following neural activation, and hence, allows brain activity to be examined and documented. READ MORE

3. Pathophysiological and Histomorphological Effects of One-Lung Ventilation in the Porcine Lung
Abstract : Thoracic surgical procedures require partial or complete airway separation and the opportunity to exclude one lung from ventilation (one-lung ventilation, OLV). OLV is commonly associated with profound pathophysiological changes that may affect the postoperative outcome. READ MORE

4. MRI Perfusion Measurements using Magnetic Susceptibility Effects: : Calibration Approaches and Contrast Agent Quantification
Abstract : Exchange of oxygen and nutrients between blood and tissue occurs at the capillary level of the blood system. The blood volume flow rate in the capillaries is often referred to as perfusion, and knowledge about perfusion provides important information about the function and viability of the tissue, for example, in patients with ischaemic stroke, cancer, and neurodegenerative diseases.

5. Co-injection of basic fluxes or BF flue dust with PC into a BF charged with 100% pellets : effects on slag formation and coal combustion
Abstract : Based on 100% pellets operation at BF No. 3 at SSAB Tunnplåt in Luleå a new pellet with CaO/SiO2=1 was developed during early nineties. The pellet showed good results in metallurgical laboratory test but caused slag formation problems in the bosh. READ MORE
