Inferring the global cosmic dust influx to the Earths atmosphere from lidar observations of the vertical flux of mesospheric Na
Estimates of the global influx of cosmic dust are highly uncertain, ranging from 0.4–110 t/d. All meteoric debris that enters the Earth’s atmosphere is eventually transported to the surface. The downward fluxes of meteoric metals like mesospheric Na and Fe, in the region below where they are vaporized and where the majority of these species are still in atomic form, are equal to their meteoric ...
متن کاملThe two earths of Eratosthenes.
In the third century B.C.E., Eratosthenes of Cyrene made a famous measurement of the circumference of the Earth. This was not the first such measurement, but it is the earliest for which significant details are preserved. Cleomedes gives a short account of Eratosthenes' method, his numerical assumptions, and the final result of 250,000 stades. However, many ancient sources attribute to Eratosth...
متن کاملThe resistivity of liquid rare earths
The resistivities of various liquid rare earths were calculated in a single-site t-matrix approximation. Good agreement with experiment is achieved. Spin disorder scattering is shown to be unimportant in the liquid state. The experimental resistivity data of liquid rare earths (RE) shows the following behavior [l, 21 : The resistivity p increases across the series of the trivalent RE's. The tem...
متن کاملMelting in super-earths.
We examine the possible extent of melting in rock-iron super-earths, focusing on those in the habitable zone. We consider the energetics of accretion and core formation, the timescale of cooling and its dependence on viscosity and partial melting, thermal regulation via the temperature dependence of viscosity, and the melting curves of rock and iron components at the ultra-high pressures charac...
متن کاملExtractive metallurgy of rare earths
Although most of the rare earth metals were discovered in Sweden, the industrialisation started in the Austrian Empire. This was due to the fact that the Swedish chemist Jons Fridrik Bahr (1815–1875) from Uppsala went to Heidelberg in Germany in 1855 to analyse some rare earth minerals by the spectroscope discovered recently by chemistry professor Robert Bunsen (1811– 1899) and his colleague ph...
