A Double-Jet System in the G31.41+0.31 Hot Molecular Core [PDF]
, 2012 This work presents a detailed study of the gas kinematics towards the "Hot Molecular Core" (HMC) G31.41+0.31 via multi-epoch VLBI observations of the H2O 22 GHz and CH3OH 6.7 GHz masers, and single-epoch VLBI of the OH 1.6 GHz masers.

Nature, 1882 VERY early in the history of steam navigation, attempts were made to employ the “hydraulic” on “water-jet” propeller. About 1782 Rumsey began to work in this direction, using a steam-engine to force water out at the stern of a boat, the inlet being at the bow.

Trigonometric distance and proper motions of H2O maser bowshocks in AFGL 5142 [PDF]
, 2017 We present the results of multi-epoch VLBI observations of water masers in the AGFL 5142 massive star forming region. We measure an annual parallax of $\pi=0.467 \pm 0.010$ mas, corresponding to a source distance of $D=2.14^{+0.051}_{-0.049}$ kpc. Proper

Where surface physics and fluid dynamics meet: rupture of an amphiphile layer by fluid flow
, 2006 We investigate the fluctuating pattern created by a jet of fluid impingent upon an amphiphile-covered surface. This microscopically thin layer is initially covered with 50 $\mu$m floating particles so that the layer can be visualized.
