Sammanfattning : The general aim of this dissertation is to lay ground for the evaluation of conservation methods for historic costumes. The Royal Armoury, Stockholm has a large number of 17th century men’s garments, many of them made of silk and in need of conservation. LÄS MER
2. Orthoptic Findings and Visual Fixation in children in general and in children with surgically treated hydrocephalus
Sammanfattning : Background: The ocular motor system is complex and dependent on the cooperation of many different areas of the brain. Ocular motor functions may be disturbed by various factors resulting in strabismus, and abnormal fixational behaviour, which may interfere on a multitude of visual functions. LÄS MER
Sammanfattning : The global oil refining industry with its present product distribution essentially shifted towards fuels such as gasoline and diesel will most likely hold the fort for considerable time. However, conditions are changing and refinery survival will very much depend on long-term planning, process and product flexibility and being at the frontiers of refining technology, a technology where catalysts play leading roles.

Sammanfattning : Interactions between surfaces and molecules play a central role in various fields where catalysis is one example. In order to understand different surface processes, physicochemical characterisation of the surface materials and molecules is required. LÄS MER
Sammanfattning : Catalytic oxidation of carbon monoxide (CO) continues to be important due to its wide applicability in emission control, in-door air cleaning, fuel cell efficiency enhancement, chemical feedstocks purification etc. The transportation sector emits most of the CO emissions. LÄS MER
