Elasticity and lattice dynamics of enstatite at high pressure
[1] The behavior of synthetic-powdered 57Fe-enriched enstatite (Mg0.980Fe0.020(5))(Mg0.760Fe0.240)Si2O6 has been explored by X-ray diffraction (XRD) and nuclear resonant inelastic X-ray scattering (NRIXS). The Pbca-structured enstatite sample was compressed in fine pressure increments for our independent XRD measurements. One structural transition between 10.1 and 12.2 GPa has been identified f...
متن کاملIn-situ Measurement of Elastic Velocity Contrast between MgSiO3 Enstatite Polymorphs at High Pressure
Introduction Orthopyroxene is an important mineralogical constituent of petrological models of the Earth’s upper mantle. Therefore, the reconstructive (or first-order) phase transformation between orthoenstatite (OEN, orthorhombic symmetry, space group Pbca) and highpressure clinoenstatite (HP-CEN, monoclinic symmetry, space group C2/c) is of great interest for geophysical applications. In part...
متن کاملBreak Down, and Delayed Repair
We present a single server in which customers arrive in batches and the server provides service one by one. The server provides two heterogeneous service stages such that service time of both stages is different and mandatory to all arriving customers in such a way that, after the completion of first stage, the second stage should also be provided to the customers. The server may subject to ran...
متن کاملAnother way to break down
hen yeast secretory proteins are improperly folded, the ER quality control system directs them into the HRD/DER pathway, which targets the proteins for degradation. Blocking the HRD/DER pathway, however, does not completely stop degradation, implying that there must be an alternative way to destroy misfolded secretory proteins. Haynes et al., reporting on page 91, have now characterized that pa...
متن کاملWhen industrial relations break down.
The Government has taken a further step towards devolving responsibility for industrial relations policy to local health authorities. New guidelines on handling industrial disputes published by the DHSS express the Government's determination to stand well back from these and not interfere: "Ministers want NHS management to know that, having issued this guidance, they would hope not to intervene...
