1. Electronic materials : growth and characterisation
Sammanfattning : In this thesis the InSb(111), InAs(111) and GaSb(001) surfaces have been studied by means of time- and angle-resolved photoemission spectroscopy based upon the femtosecond laser system. The pump-and-probe technique allows to analyse both electron states in the valence band and normally unpopulated electron states above the valence band, which can be occupied by transiently excited carriers at the optically pumped surface.

2. The Development of a European Fire Classification System for Building Products - Test Methods and Mathematical Modelling
Sammanfattning : The fire technical properties of products are determining factors for the initiation and growth of fires. Measurement of fire technical properties and the understanding of how they relate to real hazards are therefore important for fire safety. LÄS MER
3. Phospholipase A2 in nerve injury and axonal outgrowth
Sammanfattning : This thesis deals with processes coupled to injury in the peripheral nervous system (PNS), with a general aim to investigate the role of phospholipase A2 (PLA2) enzymes in axonal outgrowth. The axonal outgrowth of dorsal root ganglia (DRG) neurons in vitro was reduced by several different inhibitors of PLA2 activity and enhanced by an activator of this enzyme. LÄS MER
4. The expression and function of protein kinase C isoforms in differentiating neuroblastoma cells
Sammanfattning : The human neuroblastoma cell line SH-SY5Y can be induced to differentiate into a neuronal sympathetic phenotype after treatment with 16 nM 12-O-tetradecanoyl phorbol 13-acetate (TPA) in serum, or by a combination of the growth factors basic fibroblast growth factor and insulin-like growth factor-I (bFGF/IGF-I). SH-SY5Y cells stably transfected with TrkA, the nerve growth factor (NGF) receptor, differentiate in response to NGF. LÄS MER
5. A New Model for Room Acoustic Prediction and Auralization
Sammanfattning : The development of two room acoustic prediction models and auralization methods are described. The first prediction model is a combination of two well known algorithms with some extensions; the image source model and ray-tracing. LÄS MER
