1. Capture-based mud crab (Scylla serrata) aquaculture and artisanal fishery in East Africa- Practical and ecological perspectives : Mud crab ecology and aquaculture
Sammanfattning : Mud crab Scylla serrata is a crustacean that spends most of its life cycle in the mangrove environment throughout its range. Fishery and aquaculture of this crab are significant economic activities in coastal areas in the tropics and sub-tropics because of the meat quality and nutritional value. LÄS MER
2. Observations of young core collapse supernova remnants
Sammanfattning : Studies of young remnants offer an opportunity to test theoretical models of stellar evolution, explosion models and nucleosynthesis, as well as our understanding of the compact objects in the centre of the exploded stars.The first part of the thesis involves observations of the Crab nebula.

3. Measurements of hard X-ray polarization from the Crab and Cygnus X-1
Sammanfattning : Polarimetry provides insights into the emission mechanisms of astrophysical sources by elucidating their magnetic field and geometry. Hard X-rays are produced in \mbox{regions} with strong magnetic fields or strong gravitational effects, which makes them a probe of extreme environments. LÄS MER

5. Fisheries biology of the edible crab (Cancer pagurus) in the Kattegat and the Skagerrak - implications for sustainable management
Sammanfattning : The European edible crab (Cancer pagurus) is exploited to a varying degree in its area of distribution. Landings in United Kingdom and Ireland may have peaked around year 2000, reaching 25 000 and 13 000 tonnes, respectively but have slightly decreased since. LÄS MER
