Observations and scaling of travelling bubble cavitation
Recent observations of growing and collapsing bubbles in flows over axisymmetric headforms have revealed the complexity of the ' micro-fluid-mechanics ' associated with these bubbles (van der Meulen & van Renesse 1989; Briangon-Marjollet et al. 1990; Ceccio & Brennen 1991). Among the complex features observed were the bubble-tobubble and bubble-to-boundary-layer interactions which leads to the ...

متن کاملFUSE Observations of the Loop I/Local Bubble Interaction Region
We used the FUSE (Far Ultraviolet Spectroscopic Explorer) satellite to observe O VI emission along two sightlines towards the edge of the interaction zone (IZ) between the Loop I superbubble and the Local Bubble. One sightline was chosen because material in the interaction zone blocks distant X-ray emission, and should thus do the same for non-local O VI emission. We measured an O VI intensity ...
متن کاملPlant-ants feed their host plant, but above all a fungal symbiont to recycle nitrogen.
In ant-plant symbioses, plants provide symbiotic ants with food and specialized nesting cavities (called domatia). In many ant-plant symbioses, a fungal patch grows within each domatium. The symbiotic nature of the fungal association has been shown in the ant-plant Leonardoxa africana and its protective mutualist ant Petalomyrmex phylax. To decipher trophic fluxes among the three partners, food...
متن کاملExtensive observations of CO2 carbon isotope content in and above a high-elevation subalpine forest
[1] The dynamics of forest-atmosphere CO2 carbon isotope exchange were examined in a coniferous forest in Colorado, United States. Tunable diode laser absorption spectrometry provided extensive characterization of the carbon isotope content (dC) of CO2. Observed patterns in d C of forest air were associated with photosynthesis, respiration, and atmospheric boundary layer dynamics. Similar relat...
