1. On laser Doppler flowmetry : methods and microvascular applications
Abstract : A laser Doppler flowmeter for non-invasive microcirculatory blood flow studies has been developed. The tissue under study is illuminated by laser light (helium-neon laser, output power 2 mW) via an optical fibre and the Doppler shift oflight scattered in moving red cells is analysed. READ MORE

2. Laser doppler tissue flowmetry : fiberoptic methods in microvascular research
Abstract : Laser Doppler flowmetry (LDF) constitutes a method for measuring the flux of blood cells in the microcirculatory bed. Photons are scattered in the moving blood cells, where they undergo a frequency shift according to the Doppler principle. READ MORE

3. Sampling depth in Laser Doppler flowmetry
Abstract : The influence of probe design on the measuring depth in laser Doppler flowmetry using a 632.8 nm light source has been investigated by in vivo models and Monte Carlo simulations. Five different probe configurations were used to measure perfusion in feline intestine to which a constant blood flow was applied. READ MORE

4. The Hand in Manual Work - Physiological and Psychophysical studies
Abstract : This thesis focuses on the hand in manual work. In particular, we have studied what happens to skin and muscles when gripping a hand tool. Different aspects of gripping that will be discussed are: pressure on the hand, effects on the skin blood flow, muscle activity and the use of wrist orthoses. READ MORE

5. Experimental studies on Damage Control Surgery and Intraabdominal Hypertension
Abstract : Damage control surgery (DCS) offers an alternative to the traditional surgical management of complex or multiple injuries in critically injured patients. If a patient survives the initial phase of DCS, complications may occur, one of these being intraabdominal hypertension (IAH) and it´s potential development into the abdominal compartment syndrome.
