### alteration:

Compression
* Most compression affects lungs.
  - the crystalline structure of the snowpack
* characteristic property of sound waves.
* damping slows the shock when it is being compressed.
* dramatic process, and dramatic processes often change people.
* force that presses on a beam in one direction.
* generates pressure.
* happens when molecules are forced, or pressed, together.
* has pressure.
* help maintain some blood flow to the brain, lungs and heart.
* increases air pressure
* is also another type of filter for audio.
* is an active area of research in the computer field
  - important factor in the economics and efficacy of digital preservation
  - industry yardstick that measures the hardness of the ball
  - concentration
  - encoding
  - fundamental to the delivery of multimedia content
  - important in managing the size of image collections
  - in the bones and tension is in the fascia
  - like dehydrating food, it becomes smaller and packed closer together
  - produced by two forces pushing toward each other in the same straight line
  - resistance to being pushed together or crushed
* is the amount of pressure hose put on the leg
  - coding of data to reduce file size or tbe bit rate of a stream
  - force that s acts to shorten or compress the object it is acting on
  - method that everyone uses to deal with the speed constraint
  - most common type of stress associated with folds
  - opposite of tension
* is the process by which image data is reduced to require less storage space
  - in which files are made smaller or larger to be used by a computer
  - of shrinking, or compressing files
  - removal of redundant information
  - used for datalink Communications
* is used to create files that take up less disk space
  - help minimize the amount of swelling that occurs
  - speed blood flow to the muscles for greater relaxation
  - support and immobilize the ankle
  - useful to effectively loosen and relax muscles after training or competition
* is when a file or program is crunched down to use up less space
  - all of the fuel is squeezed
* load which shortens or compresses a structure.
* makes pressure.
* means reducing the number of bits in the digital representation of a signal.
* measure of the ball's hardness.
* occurs when the size and shape of the thoracic outlet is altered.
* process that reduces file size by removing redundant or less important information.
* produces pressure
  - the release of electrons
* provides assistance.
* pushing force - it squashes materials.
* refers to how a machine compresses the images on a document for faxing
  - shrinking of images' sizes so that they take up less space
  - the method of reducing information in an image to make a smaller file size
* retain organic matter, usually more or less coalified.
* simply measures how much the shape a golf ball changes under a constant weight.
* way of life.
* way to make the same data take up less space
  - reduce file size without decreasing the size of the image in pixels
+ Four-stroke engine: Motors
  * The 'four-stroke engine'  is an internal combustion engine. Intake means to pull in the fuel. Compression is when all of the fuel is squeezed. Exhaust is the waste smoke.

### alteration | compression:

Chest compression
* are alternated with breaths
  - done to pump the heart
* can also slow the heart.
* replace the heartbeat when it has stopped.
