Et lite pekk tesies

Nordlit, 2005
I det ytre er Vett og Uvett ei ganske lita bok, men den ruver som et storverk i nordnorsk litteratur. Og den har en posisjon i nordnorsk folkeliv og i nordnorsk bevissthet som ingen andre verdslige bøker har hatt - kanskje unntatt Nordlands Trompet. I det ytre ganske beskjeden, altså, men likevel et slags kulturelt landemerke, et fast punkt man som ...

Antibacterial Properties of PEKK for Orthopedic Applications [Corrigendum]

International Journal of Nanomedicine, 2021
Wang M, Bhardwaj G, Webster TJ. Int J Nanomedicine. 2017;12:6471–6476.   The authors have advised Figure 7 on page 6475 is incorrect. The authors inadvertently included a duplicate image for the live/dead Staphylococcus epidermidis and Pseudomonas aeruginosa PEEK samples shown in Figures 6 and 7, respectively. The correct Figure 7 is
