Physics and applications of electrodynamic space tethers [PDF]

open access: yes, 2004
Basic effects and dynamical and electrical contact issues in the physics of (electrodynamic space) bare tethers are discussed. Scientific experiments and powerpropulsion applications, including a paradoxical use of bare tethers in outer-planet ...

Stability and solubility of arsenopyrite, FeAsS, in crustal fluids.

open access: yes, 2002
The stability and solubility of natural arsenopyrite (FeAsS) in pure water and moderately acid to slightly basic aqueous solutions buffered or not with H2 and/or H2S were studied at temperatures from 300 to 450°C and pressures from 100 to 1000 bar.

Lake Mahega: a mesothermic, sulphato-chloride lake in western Uganda

open access: yes, 1972
In May, 1971, Lake Mahega had pronounced mesothermy (40.W C at one metre). Solar heating of a bloom of baeteria and the blue-green alga, Synechococcus bacillaris Butch., probably caused the high temperature. A total ionic concentration gradient increasing from 192,600 mg 1itre-1 at the surface to 415,200 mg•litre- 1 at three metres stabilized the ...

Bare-tether cathodic contact through thermoionic emission by low work-function materials [PDF]

open access: yes, 2012
A new material, C12A7 : electride, which might present a work function as low as 0.6 eV and moderately high temperature stability, was recently proposed as coating for floating bare tethers.

THE SIGNIFICANCE OF LINEAR TRENDS AND CLUSTERS OF FAULT-RELATED MESOTHERMAL LODE GOLD MINERALIZATION

open access: yesEconomic Geology, 2007
Gold deposits from the Laverton region, Western Australia, form both linear trends and cluster-like distributions in map view, associated with regional-scale shear zone systems. Clusters of deposits are common, and they form 5 × 5 km domains, spaced every 15 to 20 km.
