11. Organocatalytic Acylation for the Kinetic Resolution of Secondary Aryl Alcohols : Synthetic Applications and Mechanistic Studies
Sammanfattning : The research described in this thesis focuses on the catalytic acylative kinetic resolution (KR) of aromatic secondary alcohols, using a planar-chiral 4-(dimethylamino)pyridine (DMAP) organocatalyst.In the first part of this thesis, the substrate scope of the above mentioned process was expanded to aromatic secondary alcohols that contain an extra functional group in the alkyl moiety, such as 1,2-azido alcohols, 2-hydroxy-2-aryl-ethylphosphonates and 2-hydroxy-2-aryl esters.

12. Carbohydrate degradation and dissolution during Kraft cooking : Modelling of kinetic results
Sammanfattning : Chemical pulp fibres from wood are commonly used in products associated with packaging as well as with printing and writing. The prevalent way of liberating fibres is by subjecting wood chips to Kraft cooking. This process has a history of almost 130 years and should be both well described and well established. LÄS MER
13. Laser on kinetic operator
Sammanfattning : This thesis highlights a variety of aspects within the field of mobile robots. The hinge is system architecture for mobile robots. For a mobile robot to be put into operation all necessary systems have to be functioning and control mechanisms have to be established. The robot may be set to operate autonomously as well as remotely controlled. LÄS MER
14. Interfacial kinetic ski friction
Sammanfattning : It is no doubt, that the ski glide over the snow is a very complicated object of research. However, ski glide is just a one area of many other areas of human knowledge. As a rule, the scientists and practitioners, who work in these areas, operate with some publicly expressed more or less solid hypotheses. LÄS MER
15. Development of in silico methods to aid chemical risk assessment : focusing on kinetic interactions in mixtures
Sammanfattning : The environment and biota are constantly exposed to numerous chemicals through contaminated food, soil, water, and air. These chemicals can be taken up and distributed to reach sensitive tissues where they may cause various effects. Many of these chemicals lack data on their environmental and human health effects.
