Due to the much higher maintenance and replacement expenses of the offshore wind turbine structures, more attention should be paid for a reliable lifetime analysis of them. Meanwhile, the cyclic nature of wave and wind loads together with the corrosive effects from the sea water are major factors for the creation and growth of flaws and cracks in offshore structures. These cracks can be the cau...

The oxidative stress response is characterized by various effects on a range of biologic molecules. When examined at the protein level, both expression levels and protein modifications are altered by oxidative stress. While these effects have been studied in the past by classic biochemical methods, the recent onset of proteomics methods has allowed the oxidative stress response to be studied on...
