Edema
Edema (American English), also spelled oedema (British English), and also known as fluid retention, swelling, dropsy and hydropsy, is the build-up of fluid in the body's tissue (biology), tissue. Most commonly, the legs or arms are affected. Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. Other symptoms depend on the underlying cause. Causes may include Chronic venous insufficiency, venous insufficiency, heart failure, kidney problems, hypoalbuminemia, low protein levels, liver problems, deep vein thrombosis, infections, kwashiorkor, angioedema, certain medications, and lymphedema. It may also occur in immobile patients (stroke, spinal cord injury, aging), or with temporary immobility such as prolonged sitting or standing, and during menstruation or pregnancy. The condition is more concerning if it starts suddenly, or pain or shortness of breath is present. Treatment depends on the underlying cause. If the underlying mechanism involve ...

Die Swell
In fluid dynamics, the die swell, extrudate swell or Barus effect, is a common phenomenon in polymer processing. Die swell occurs in instances of polymer extrusion, in which a stream of polymeric material is forced through a die, a specialized tool in manufacturing to shape or cut polymeric materials. Die swell is an instance where a polymer stream is compressed by entrance into a die, and is followed by a partial recovery or "swell" back to the former shape and volume of the polymer after exiting the die, hence the term die swell. The Barus effect is named after his discoverer Carl Barus, who published about it in 1893. Explanation Die swell is a phenomenon directly related to entropy Entropy is a scientific concept, most commonly associated with states of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the micros ... and the relaxation of the polymer within the ...

Swelling Capacity
The swelling capacity of a polymer is the amount of a liquid that can be absorbed by it. This test can done by two methods: # Beaker test method # Tea bag A tea bag (or teabag) is a small, porous, sealed bag or Packet (container), packet typically containing tea leaves (''Camellia sinensis'') or the leaves of other herbs, which is immersed in water to steeping, steep and make an infusion. Origina ... test method Beaker test method In this method * A small amount of superabsorbent polymer material is taken (0.1g) and it is placed in the beaker. * 100 ml of deionized water is poured into the beaker. * After 20 min the swollen polymer was separated by using ilter paper* By weighing the polymer, one can find the swollen capacity of the SAP material. Tea bag test method * In this method, 0.1 g of SAP material is placed into a permeable bag, which is suspended over excess water in a beaker. * Wait 20 min. and weigh the bag and then calculate the percentage of swelling throug ...

Neutron-induced Swelling
Neutron-induced swelling is the increase of volume and decrease of density of materials subjected to intense neutron radiation. Neutrons impacting the material's lattice rearrange its atoms, causing buildup of dislocations, voids, and Wigner energy. Together with the resulting strength reduction and embrittlement, it is a major concern for materials for nuclear reactor A nuclear reactor is a device used to initiate and control a Nuclear fission, fission nuclear chain reaction.

Swelling Index
Swelling index may refer to the following material parameters that quantify volume change: * Crucible swelling index, also known as free swelling index, in coal assay * Swelling capacity The swelling capacity of a polymer is the amount of a liquid that can be absorbed by it.
