11. The Prevalence of Radioactivity in a Number of Non-Nuclear Industries
Sammanfattning : Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. LÄS MER
12. Cell responses in infected and cystic fibrosis respiratory epithelium
Sammanfattning : Respiratory Epithelium. Örebro Studies in Medicine 99. Cystic fibrosis (CF) is caused by a mutation in a cAMP-activated chloride (Cl-) channel (CFTR). Mortality and morbidity in CF is mainly due to the deregulated responses of the airway epithelial cells. LÄS MER
13. Corrosion of steel in concrete at various moisture and chloride levels
Sammanfattning : About 7000 concrete bridges in Sweden were built before 1965. The annual cost for maintenance of these bridges is about 0.6% of their total value. The cooling water tunnels at Swedish nuclear power plants have been exposed to seawater for about 30-40 years. LÄS MER
14. Durability of Reinforced Concrete under Impressed Current Cathodic Protection
Sammanfattning : Impressed current cathodic protection (ICCP) and prevention (ICCPre) are reliable and efficient techniques to stop, control and postpone corrosion in reinforced concrete structures. However, the wide application of this technique has been limited by the high cost of the anode system. LÄS MER
15. Chloride Induced Corrosion of Reinforcement Steel in Concrete - Threshold Values and Ion Distributions at the Concrete-Steel Interface
Sammanfattning : The chloride threshold value (Cth), or critical chloride content, is defined as the chloride concentration at the depth of the reinforcement, which initiates the depassivation of steel in concrete. However, very limited information is available regarding the chloride distributions at the interface with the steel. LÄS MER
