Small hydrocarbon molecules in cloud-forming Brown Dwarf and giant gas planet atmospheres [PDF]

, 2013
We study the abundances of complex carbon-bearing molecules in the oxygen-rich dust- forming atmospheres of Brown Dwarfs and giant gas planets. The inner atmospheric re- gions that form the inner boundary for thermochemical gas-phase models are ...

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

Deep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

The shaft response characteristics of hydrostatic thrust gas bearings with fluid damper.

Journal of the Japan Society for Precision Engineering, 1991
In this paper, the shaft response characteristics of hydrostatic thrust gas bearings with fluid damper are described. In hydrostatic gas bearings, the both clearances at which stiffness reaches its maximum value and damping reaches its minimum value are well known to be at almost the same.
