This is kind of like when you "crack" your knuckles... a bubble of nitrogen gas actually gets "sucked" out of the blood/tissue surrounding the knuckle into the joint. In this case it has happened in a spinal disk that is degenerating (wearing out)... It's fairly rare. Nothing to worry about as long as that is what it is... Very very rarely, early infections can look something like this in a disc, but your doctor has run the appropriate lab tests to make sure it's nothing to be concerned about... (otherwise you wouldn't be asking about something on an XRay report)
The presence of linear radiolucency in the disk space result in space narrowing with vacuum disc. It is associated with degenerative disk disease.
If you have a booster you need a vacuum line to perform effectively, disc or drum.
vacuum assisted disc brakes
That would be the vacuum power booster for the brakes.
Degeneration of the L5-S1 disc refers to the breakdown or wear-and-tear of the disc located between the fifth lumbar vertebra and the first sacral vertebra in the spine. The vacuum phenomenon is a radiographic finding where gas accumulates within the intervertebral disc space, typically seen in degenerated discs. This phenomenon is a result of the degenerative changes in the disc causing a decrease in pressure within the disc space, allowing gas to enter and form a vacuum. This condition can be associated with back pain, radiculopathy, and other symptoms related to spinal degeneration.
In science, vacuum refers to a space entirely devoid of matter, such as air or other gases. This absence of particles in a vacuum allows for unique experimental conditions to study various phenomena. Vacuum is often used in scientific research, particularly in fields like physics and chemistry.
Engages automatic locking hubs on for wheels drives with automatic hubs.
Maxwell's equations in a vacuum describe how electric and magnetic fields interact and propagate. They show that electromagnetic waves can travel through a vacuum at the speed of light. This has implications for various phenomena, such as the transmission of radio waves, the behavior of light, and the functioning of electronic devices.
You should have a vacuum plate with a hole in it for the he hose to be plugged into. The vacuum plate is a disc shaped object that fits over the leaf basket in the pools static skimmer box. If you cant find one you may have to get one from a pool shop.
A vacuum phenomenon is a oval or linear radiolucency in the intervertebral disc space that corresponds to a gas, which is a typical finding of osteocronosis. This is the specific sign for bone ischemia.
An accretion disc is a structure formed around a central object, often a black hole or a young star, as it gathers material from its surrounding environment. The material in the disc spirals inward due to gravity, releasing energy in the form of heat and light. Accretion discs play a key role in powering some of the brightest phenomena in the universe, such as quasars and X-ray binaries.
Should be on top or side of valve covers round disc like thing usually silver & has rubber vacuum hose going to it
