Parallel compression, also known as New York compression, is a dynamic range compression technique used in sound recording and mixing. Parallel compression, a form of upward compression , is achieved by mixing an unprocessed 'dry', or lightly compressed signal with a heavily compressed version of the same signal.
One of the most important functions of the ribs and diaphragm is the change in volume of the thorax that helps inspiration and expiration. [2] In general, the ribs move around two axes. [ 1 ] The anterior end of the rib is lower than the posterior end; therefore, during elevation of the rib, the anterior end also moves forwards.
In both tests, the patient is placed in a standing or sitting position, and the arms are raised parallel to the ground in the scapular plane. [2] The tests differ in the rotation of the arm; in the empty can test, the arm is rotated to full internal rotation (thumb down) and in the full can test, the arm is rotated to 45° external rotation, thumb up.

In the theory of 3-manifolds, a compression body is a kind of generalized handlebody. A compression body is either a handlebody or the result of the following construction: Let be a compact, closed surface (not necessarily connected). Attach 1-handles to [,] along {}.
Cricoid pressure, also known as the Sellick manoeuvre or Sellick maneuver, is a technique used in endotracheal intubation to try to reduce the risk of regurgitation.The technique involves the application of pressure to the cricoid cartilage at the neck, thus occluding the esophagus which passes directly behind it.
Point of application of abdominal thrusts (between chest and navel). The hands press inward and upward. The American Red Cross, the NHS, the European Resuscitation Council and the Mayo Clinic recommend a repeating cycle of five back slaps and five abdominal thrusts. [14] [15] [1] [2] They are not recommended on children below the age of one.
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. [1] Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse. [2]
The tectorial membrane of atlanto-axial joint (occipitoaxial ligaments) is a tough membrane/ [1] broad, strong band [2] representing the superior-ward prolongation of the posterior longitudinal ligament (the two being continuous). [3] [1] [2] It attaches inferiorly onto (the posterior aspect of [2]) the body of axis. [3] It broadens superiorly.
