1. Radio meteors above the Arctic Circle : radiants, orbits and estimated magnitudes
Sammanfattning : This thesis presents results based on data collected with the 930 MHz EISCAT UHF radar system and three SKiYMet specular meteor radars. It describes in detail a method for meteoroid orbit calculation. The EISCAT UHF system comprises three identical 32 m parabolic antennae: one high-power transmitter/receiver and two remote receivers.

2. Quasar host galaxies at intermediate and high redshifts
Sammanfattning : Quasars form one of the most energetic phenomena in the universe, and can be traced out to very large redshifts. By studying the galaxies which host the active nuclei, important insights can be gained into the processes that trigger and maintain the quasar powerhouse. LÄS MER
3. A comparison of the magnitudes of genetic variation of some quantitative characters in salmon (Salmo salar L.) and guppy (Lebistes reticulatus)

5. Neck-Injuries in Rear-End Car Collisions: Sites and Biomechanical Causes of the Injuries, Test Methods and Preventive Measures
Sammanfattning : The present work addresses the problem of neck injuries following rear-end car collisions. Biomechanics and sites of the injuries have been investigated. A new dummy neck has been developed and used to study the influence of different seat properties on occupant kinematics. LÄS MER
