Numerically investigating the crushing of sandstone by a tooth hob

Frontiers of Structural and Civil Engineering Pages 964-979 doi: 10.1007/s11709-023-0978-6

Abstract: To investigate the mechanical process that occurs between rocks and tooth hobs, the crushing of sandstonewith a tooth hob was simulated using reconstructed multi-mineral mesoscopic numerical models of variousWhen a piece of sandstone is crushed by the tooth of a hob rolling at a constant speed, the resultantreaction forces of the sandstone on the tooth first hinder and then contribute to the rolling of theBecause the tooth was subjected to reaction forces from the sandstone, forces and moments were applied

Experimental investigation of fatigue behavior of spur gear in altered tooth-sum gearing

H. K. SACHIDANANDA, Joseph GONSALVIS, H. R. PRAKASH

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 3, Pages 268-278 doi: 10.1007/s11465-012-0331-6

Abstract:

This paper deals with the contact stress, power loss, and pitting of spur gear tooth in altered tooth-sumgearing for a tooth-sum of 100 teeth when altered by±4% tooth-sum.against the standard tooth-sum gearing.The tooth loads for the experimental investigations were determined considering the surface durabilityThe negative alteration in the tooth-sum performed better than the positive alteration in a tooth-sum

Primary cilia in hard tissue development and diseases

Frontiers of Medicine 2021, Volume 15, Issue 5, Pages 657-678 doi: 10.1007/s11684-021-0829-6

Abstract: Bone and teeth are hard tissues. Hard tissue diseases have a serious effect on human survival and quality of life. Primary cilia are protrusions on the surfaces of cells. As antennas, they are distributed on the membrane surfaces of almost all mammalian cell types and participate in the development of organs and the maintenance of homeostasis. Mutations in cilium-related genes result in a variety of developmental and even lethal diseases. Patients with multiple ciliary gene mutations present overt changes in the skeletal system, suggesting that primary cilia are involved in hard tissue development and reconstruction. Furthermore, primary cilia act as sensors of external stimuli and regulate bone homeostasis. Specifically, substances are trafficked through primary cilia by intraflagellar transport, which affects key signaling pathways during hard tissue development. In this review, we summarize the roles of primary cilia in long bone development and remodeling from two perspectives: primary cilia signaling and sensory mechanisms. In addition, the cilium-related diseases of hard tissue and the manifestations of mutant cilia in the skeleton and teeth are described. We believe that all the findings will help with the intervention and treatment of related hard tissue genetic diseases.
