Hepatozoon fitzsimonsi (Dias, 1953) is a frequently found haemogregarine of southern African tortoises. At the time of this species’ reassignment from the genus Haemogregarina to Hepatozoon, developmental stages such as sporocysts and sporozoites were o
The second part of the thesis has a broader scope than the first and is multidisciplinary in its nature with inspiration from the research field of Science and Technology Studies (STS). The approach is to critically analyse stakeholder percep-tions regarding CCS, with a specific focus on the ...

Post-breakdown stage in transformer oil consisted of vapour channel between the electrodes. This channel was created during breakdown and it expanded into space and then contracted. Time development of its length and diameter from records of high-speed camera were determined. The times of expansion ...
8), the temporal variation of the decomposition-degradation state could not be evaluated until day 30 due to small sample sizes, and thus low statistical power. Only one out of 30 carcasses of small-sized birds, and three out 30 of medium-sized birds, remained in the field up to day 30...
