Midplane sedimentation of large solid bodies in turbulent protoplanetary discs
We study the vertical settling of solid bodies in a turbulent protoplanetary disc. We consider the situation when the coupling to the gas is weak or equivalently when the particle stopping time τst due to friction with the gas is long compared to the orbital timescale Ω. An analytical model, which takes into account the stochastic nature of the sedimentation process using a Fokker-Planck equati...

Normally, Descemet's membrane is secreted as a hyaline tissue by the endothelial corneal cells during intra-uterine life; the exact point of development at which it appears is not definitely ...

15 صفحه اولHyaline infiltration of the eyelid.
The term "hyaline degeneration ", first employed by von Recklinghausen (1883), denotes a physical state rather than a chemical composition. " Hyalin" includes a heterogenous group of substances which share the properties of being translucent, refractile, and structureless (Gk, hyalos-glass). They stain readily with acid dyes, are resistant to strong acids and alkalis, and are all of a protein n...
