16. Air diffusion and solid contaminant behaviour in room ventilation : a CFD based integrated approach
Sammanfattning : One of the most fundamental human needs is fresh air. It has been estimated that people spend comparatively much time in indoor premises. That creates an elevated need for high-quality ventilation systems in buildings. The ventilation airflow rate is recognised as the main parameter for measuring the indoor air quality. LÄS MER
17. Design of Hospital Operating Room Ventilation using Computational Fluid Dynamics
Sammanfattning : The history of surgery is nearly as old as the human race. Control of wound infection has always been an essential part of any surgical procedure, and is still an important challenge in hospital operating rooms today. For patients undergoing surgery there is always a risk that they will develop some kind of postoperative complication. LÄS MER
18. Ventilation/Perfusion Matching and its Effect on Volatile Pharmacokinetics
Sammanfattning : The mismatching of alveolar ventilation and perfusion (VA/Q) is the major determinant of impaired gas exchange. The gold standard for analyzing VA/Q distribution is the multiple inert gas elimination technique (MIGET), conventionally based on gas chromatography (GC), and, although simple in principle, a technically demanding procedure limiting its use.

19. Quantification of pulmonary scintigraphy
Sammanfattning : Modern nuclear medicine techniques, such as SPECT (single photon emission computed tomography), enable quantification and localisation of lung function in small lung elements, but appropriate methods are not yet available. The aim of the present project was therefore to develop and evaluate methods for mapping lung function in planar scintigrams and in SPECT. LÄS MER
20. Passive Houses in Sweden. From Design to Evaluation of Four Demonstration Projects
Sammanfattning : The use of energy is a major global issue both according to climate changes but also in the aspect of national safety tied to the trade with energy sources. Of the total energy use in the member states of the European Union, about 40% is used in residential and commercial buildings. LÄS MER
