Oxygen self-diffusion ‘‘fast-paths’’ in titanite single crystals and a general method for deconvolving self-diffusion profiles with ‘‘tails’’
Like most other minerals, titanite rarely if ever forms perfect crystals. In addition to the point defects that might affect lattice diffusion, there may be extended lineor planar defects along which fast diffusion could occur. During the course of an experimental study of oxygen lattice diffusion in titanite, we found that almost all of the O uptake profiles produced in natural titanite crysta...

متن کاملThermodynamic properties of polarized liquid 3He along different isentropic paths
The dependence of some thermodynamic properties of spin-polarized liquid 3He such as velocity of sound, adiabatic index, isentropic compressibility and temperature on the spin polarization has been investigated along different isentropic paths. The Lennard-Jones potential has been used in our calculations. It has been found that for higher values of entropy, the spin polarization has greate...
متن کاملAbsolute Differences Along Hamiltonian Paths
We prove that if the vertices of a complete graph are labeled with the elements of an arithmetic progression, then for any given vertex there is a Hamiltonian path starting at this vertex such that the absolute values of the differences of consecutive vertices along the path are pairwise distinct. In another extreme case where the label set has small additive energy, we show that the graph actu...
متن کاملA transient diffusion model of the cornea for the assessment of oxygen diffusivity and consumption.
PURPOSE Oxygen diffusivity and consumption in the human cornea have not been directly measured yet; current models rely on properties measured in vitro in rabbit corneas. The aim of this study was to present a mathematical model of time-dependent oxygen diffusion that permits the estimation of corneal consumption and diffusivity. METHODS The current oxygen diffusion model was extended to incl...
