6. Cardioplegia and cardiac function : evaluated by left ventricular pressure-volume relations
Sammanfattning : Purpose: This thesis is focused on studies of blood cardioplegia in order to evaluate regimens of myocardial protection during cardiac surgery. To further bring down operative mortality and morbidity, in patients with acutely ischaemic hearts, an optimal peroperative myocardial management is essential. LÄS MER
7. Ab initio Lattice Dynamics : Hydrogen-dense and Other Materials
Sammanfattning : This thesis presents a theoretical study of materials under high pressure using ab initio lattice dynamics based on density functional theory and density functional perturbation theory using both super-cell and linear response approach. Ab initio lattice dynamics using super-cell approach is applied to compare our theoretical predictions with experimental findings. LÄS MER
8. Respiratory mechanics during mechanical ventilation in health and in disease
Sammanfattning : The elastic pressure-volume (Pel-V) curve of the respiratory system can be used as a guide for improved ventilator management. It may indicate risks of lung damage associated with collapse or overdistension of lung units. LÄS MER
9. Spirodynamics. New methods for continuous monitoring of respiratory mechanics in ventilator-treated patients
Sammanfattning : Introduction: Ventilator treatment is often life-saving but has the inherent risk of causing damage to lung tissues. Overdistension and repetitive collapsing/opening of alveoli should be avoided. Monitoring of respiratory mechanics has a central role in accomplishing this. LÄS MER
10. Dynamic Plate and Shell Equations Using Power Series Expansions - Applications Including Elasticity, Poroelasticity and Fluid Loading
Sammanfattning : Thin structures are used in a wide range of engineering applications. The subject of this thesis is the derivation of approximate equations for the dynamics of thin plates and shells using series expansion methods. LÄS MER
