1. Polymer-shelled Ultrasound Contrast Agents : Characterization and Application
Sammanfattning : Ultrasound-based imaging technique is probably the most used approach for rapid investigationand monitoring of anatomical and physiological conditions of internal organs and tissues.Ultrasound-based techniques do not require the use of ionizing radiation making the tests anexceptionally safe and painless.

2. Macroscopic Volume and Free Volume of Polymer Blends and Pressure-densified Polymers
Sammanfattning : The macroscopic volume V as a function of pressure P and temperature T is obtained from PVT measurements. PVT data is sensitive to the state of polymers and changes therein. Moreover, PVT data gives access to the free-volume fraction. LÄS MER
3. Theoretical modeling of molar volume and thermal expansion
Sammanfattning : Combination of the Calphad method and theoretical calculations provides new possibilities for the study of materials science. This work is a part of the efforts within the CCT project (Centre of Computational Thermodynamics) to combine these methods to facilitate modeling and to extend the thermodynamic databases with critically assessed volume data.

4. Transpulmonary pressure during mechanical ventilation
Sammanfattning : Background: Mechanical ventilation can aggravate lung injury by repetitive opening and closing of lung units, overdistention and undue pressure on pulmonary structures. Guidelines exist for lung protective ventilation, but individualized ventilator settings, based on partitioning of respiratory mechanics in pulmonary and chest wall complex components, would be beneficial.

5. Modeling of Energy-Efficient Robots for Lightweight, High Volume Assembly : Concepts and Optimization
Sammanfattning : Commercial and environmental demands put constant pressure on robot manufacturers to improve the efficiency of the robots they produce. Satisfying answers to efficiency questions can have a major impact on both manufacturers and users. LÄS MER
