STUDY ON SAFETY ASSESSMENT OF FLANGE CLIMB DERAILMENT AT LOW SPEED BASED ON THE RELATIONSHIP BETWEEN THE DERAILMENT QUOTIENT AND WHEEL RISE

Study on safety assessment of flange climb derailment at low speed based on the relationship between the derailment quotient and wheel rise

In railways, on-track running tests are implemented to assess running safety against flange climb derailment.Results of tests depend on the frequency component of measured data.In this paper, the relationship between the measured data of the derailment quotient, which is the assessment quantity of derailment, and wheel rise are investigated.The dat

Influence of the Nitrided Layer Structure on the Micro-Pitting and Wear Behavior of Slow-Running Nitrided External Gears

Nitriding can significantly increase the load carrying properties of gears.While the diffusion layer is primarily responsible for improving the tooth root and flank load carrying capacity, the compound layer mainly determines the tribological properties of the gear surface.In the present work, the influence of the compound layer on the tribological

De novo mitochondrial genome sequencing of Cladonia subulata and phylogenetic analysis with other dissimilar species.

In this study, the complete mitochondrial genome of Cladonia subulata (L.) FH Wigg was sequenced and assembled and then compared with those of other Cladonia Hutch species.The mitogenome of Cladonia subulata, the type species of Cladonia, consisted of a circular DNA molecule of 58,895 bp 44 genes (15 protein-coding genes, 2 rRNA genes, and 27 tRNA

A phylogenetic survey of myotubularin genes of eukaryotes: distribution, protein structure, evolution, and gene expression

Abstract Background Phosphorylated phosphatidylinositol (PtdIns) lipids, produced and modified by PtdIns kinases and phosphatases, are critical to the regulation of diverse cellular functions.The myotubularin PtdIns-phosphate phosphatases have been well characterized Front Wheel Axle in yeast and especially animals, where multiple isoforms, both ca
