Neutral buoyancy occurs when an object's average density is equal to the density of the fluid in which it is immersed, resulting in the buoyant force balancing the force of gravity that would otherwise cause the object to sink (if the body's density is greater than the density of the fluid in which it is immersed) or rise (if it is less). An ...
In meteorology, the equilibrium level (EL), or level of neutral buoyancy (LNB), or limit of convection (LOC), is the height at which a rising parcel of air is at the same temperature as its environment.

Buoyancy (/ ˈ b ɔɪ ən s i, ˈ b uː j ən s i /), [1] [2] or upthrust is a net upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.
Buoyancy reduces the apparent weight of objects that have sunk completely to the sea-floor. It is generally easier to lift an object through the water than it is to pull it out of the water. For a fully submerged object, Archimedes' principle can be reformulated as follows:
An astronaut training at the Neutral Buoyancy Laboratory at the Johnson Space Center. Neutral buoyancy simulation with astronauts immersed in a neutral buoyancy pool, in pressure suits, can help to prepare astronauts for the difficult task of working while outside a spacecraft in an apparently weightless environment.
Russell as an indirect tank commander could be a low-key shrewd move, as the 6-5 guard isn't exactly an efficient offensive player, nor does he play the caliber of defense that helps you win games.
Saquon Barkley’s pursuit of Eric Dickerson’s 40-year-old rushing record could get grounded by his coach. Nick Sirianni’s decision is more difficult than it seems. Barkley needs 101 yards ...
Toby Fischer lives in South Dakota, where just 27 doctors are certified to prescribe buprenorphine -- a medication that blunts the symptoms of withdrawal from heroin and opioid painkillers. A Huffington Post analysis of government data found nearly half of all counties in America don't have such a certified physician. So every month, Fischer and his mother drive to Colorado to pick up their ...
