Refilling the coral reef glass.
oral reefs around the world have suffered from 3 years of coral bleaching, following three decades of record high temperatures. It is now clear that coral reefs cannot survive, unchanged, under climate change. Their final state will depend not only on societal conviction to restore coral health but also on the ability to sustain investments and action that support this commitment. For the past ...
متن کاملTwostream modeling of plasmaspheric refilling
Plasmaspheric refilling on an L = 4 flux tube was studied by using a time-dePendent, hydrodynamic plasmaspheric flow model in which the ion streams from the tWO hemispheres are treated as distinct fluids. In the model the continuity, momentum, and energy equations of a twoion (O + and H+), quasi-neu.tral, currentless plasma are solved along aclosed geomagnetic field line; diffusive quilibrium i...
متن کاملSelf-inflating bag or Mapleson C breathing system for emergency pre-oxygenation?
BACKGROUND A crossover study was performed in healthy volunteers to compare the efficacy of a self-inflating bag with the Mapleson C breathing system for pre-oxygenation. METHOD 20 subjects breathed 100% oxygen for 3 min using each device, with a 30 min washout period. The end tidal oxygen concentration and subjective ease of breathing were compared. RESULTS There was a statistically signif...
متن کاملProtection of the Reconstructed Nipple by Using a Breathing Bag Connection Tube
Nowadays, local flap coverage methods, including the C-V breast flap compose the majority of nipple reconstruction procedures [1]. As the projection of new nipple from the C-V breast flap is basically subcutaneous fat, the reconstructed nipple tends to be flattened over the long term, especially if submitted to pressure. In addition, necrosis or abrasion may result in flap failure. For this rea...
متن کاملLoss Cone Refilling Rates in Galactic Nuclei
A gap in phase space is opened up by a binary supermassive black hole as it ejects stars in a galactic nucleus. This gap must be refilled before the single black hole that subsequently forms can disrupt or accrete stars. We compute loss cone refilling rates for a sample of elliptical galaxies as a function of the mass ratio of the binary. Refilling times are of order 1010 yr or longer in bright...
