Observations of radar speckle patterns tied to the rotation of Mercury establish that the planet occupies a Cassini state with obliquity of 2.11 +/- 0.1 arc minutes. The measurements show that the planet exhibits librations in longitude that are f...

Phosphate glass-clad optical fibers comprising amorphous Se(0.8)Te(0.2) semiconductor core were fabricated by a reactive molten core approach. The Se(0.8)Te(0.2) crystals were precipitated in core region by a postdrawing annealing process, which w...

Ab initio finite temperature molecular dynamics simulations have been used to calculate the elasticity of hcp-Fe, bcc-Fe, FeS and FeSi at core conditions. The calculated compressional wave velocities are in excellent agreement with the most recent...

M.J.S.J.hnston; R.G.J.S.rens, 1973: Electrical conductivity of molten Fe-Ni-S-C core mix. The electrical conductivity of liquid (Fe90Ni10)3S2 saturated with 2.6 weight percent carbon averages 2.7·105 mho/m at 1000°C and zero pressure. This may imply a slightly lower electrical conductivity for the earth's core than that obtained...

The estimated upper limit for core radius is 352 km for pure iron. Tidal dissipation is strong; Q at one month is 37.

An improved model of bulk anelasticity including the effect of thermal and material diffusion, quantitatively capable of explaining the observed anelasticity. Also, studies of the reflection of seismic waves from the inner-core boundary are used t...

There has been recent controversy over the discrimination between natural and anthropogenic loadings of mercury to lakes. Sediment core profiles have been interpreted as evidence that inputs to lakes have increased. Some investigators have argued,...
