Abstract After 30 years of operation, the runners four 100 MW high-head Francis turbines successively developed fatigue cracks starting from hub-side trailing-edge fillets. Assessment alternating stress in normal turbine operation revealed that levels were not nearly large enough to explain damages. Consequently, a test campaign comprising start and stop manoeuvres addition was conducted 2017. ...

dna barcoding based on a standardized region of 648 base pairs of mitochondrial dnasequences from cytochrome c oxidase 1 (cox1) is proposed for animal species identification.recent studies suggested that dna barcoding has been effective for identifying 94% of birdspecies. the proposed threshold of 10 times the average intraspecific variation could be used forthe identification and delimitation ...
