Bubbles, Bubbles Everywhere! [PDF]
Practical Neurology, 2003 Back in 1993 it had been a fairly average afternoon in the neurovascular clinic; a couple of obese, hypertensive smokers with clear-cut transient ischaemic attacks whose seemingly programmed lack of motivation to modify their vascular risk factors would subsequently challenge all the persuasive skills of my Specialist Nurse.

Molecular gas in high-mass filament WB673
Open Astronomy, 2017 We studied the distribution of dense gas in a filamentary molecular cloud containing several dense clumps. The center of the filament is given by the dense clump WB673. The clumps are high-mass and intermediate-mass starforming regions. We observed CS (2-

Giant Gamma-ray Bubbles from Fermi-LAT: AGN Activity or Bipolar Galactic Wind?
, 2010 Data from the Fermi-LAT reveal two large gamma-ray bubbles, extending 50 degrees above and below the Galactic center, with a width of about 40 degrees in longitude. The gamma-ray emission associated with these bubbles has a significantly harder spectrum (

Stability of multi-electron bubbles in liquid helium
, 2008 The stability of multi-electron bubbles in liquid helium is investigated theoretically. We find that multi-electron bubbles are unstable against fission whenever the pressure is positive.

Searching for OH maser emission towards the MIPSGAL compact Galactic bubbles [PDF]
, 2015 We conducted radio observations searching for OH 18-cm maser emission from a sample of 169 unclassified MIPSGAL compact Galactic bubbles. These sources are thought to be the circumstellar envelopes of different kinds of evolved stars.

Journal of High Energy Physics, 2006 We construct new explicit solutions of general relativity from double analytic continuations of Taub-NUT spacetimes. This generalizes previous studies of 4-dimensional nutty bubbles. One 5-dimensional locally asymptotically AdS solution in particular has a special conformal boundary structure of $AdS_3\times S^1$.

Molecular Lines of 13 Galactic Infrared Bubble Regions
, 2016 We investigated the physical properties of molecular clouds and star formation processes around infrared bubbles which are essentially expanding HII regions. We performed observations of 13 galactic infrared bubble fields containing 18 bubbles.

Coalescence Avalanches in Liquid Aluminum Foams
Metals, 2017 Coalescence is the rupture of a film between two adjacent bubbles in any type of liquid foam and has pronounced influence on the development of its macrostructure after solidification, mostly leading to larger pores and a wider size distribution ...

Acoustic bubble removal method [PDF]
, 1983 A method is described for removing bubbles from a liquid bath such as a bath of molten glass to be used for optical elements. Larger bubbles are first removed by applying acoustic energy resonant to a bath dimension to drive the larger bubbles toward a ...
