Edema
Edema, also spelled oedema, and also known as fluid retention, dropsy, hydropsy and swelling, 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 which feels tight, the area may feel 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, angioedema, certain medications, and lymphedema. It may also occur after 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 involves Hypernatremia, sodium retention, decreased salt intake and a diuretic may be used. Elevating the legs and support stockings may be useful ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Die Swell
Die swell, also known as 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. Die swell is a phenomenon directly related to entropy and the relaxation of the polymer within the flow stream. Initially, a flow stream has a constant rate before entering the die, and the polymers within the stream occupy a roughly spherical conformation, maximizing entropy. Extrusion through the die causes an increase in flow rate through the polymer flow stream. As the polymer spends time inside the die and is subject to the much increased flow rate, the poly ...

Swelling Capacity
The swelling capacity of a polymer is determined by the amount of liquid material that can be absorbed by it. This test can done by two methods: # Beaker test method # Tea bag test method Beaker test method In this method * A small amount of superabsorbent polymer A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers that can absorb and retain extremely large amounts of a liquid relative to its own mass. Water-absorbing polymers, which are cla ... 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 percentag ...

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 reactors. Materials show significant differences in their swelling resistance. See also * Radiation hardening Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), especially for environ ...

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 amount of a liquid that can be absorbed by a polymer * Shrink–swell capacity The shrink–swell capacity of soils refers to the extent certain clay minerals will expand when wet and retract when dry. Soil with a high shrink–swell capacity is problematic and is known as shrink–swell soil, or expansive soil. The amount of ... in soil mechanics * Unload-reload constant (κ) in critical state soil mechanics {{SIA Mechanics Materials science ...

Shrinkage (other)
Shrinkage may refer to: Reduction in size of a solid material *Shrinkage (casting), size reduction of liquid metal as it solidifies *Creep and shrinkage of concrete, Shrinkage (concrete), size reduction of concrete as it sets and ages *Shrinkage (fabric), size reduction of fabric when washed with water or hot water *Wood drying#Shrinkage and swelling, Shrinkage (wood), size reduction of wood as it dries Other uses *Shrinkage (accounting), loss of product inventory due to theft, damage, spoilage, etc. *Casting defect#Shrinkage defects, Shrinkage defect or shrinkage void, a casting defect caused by metal solidifying from the outside inward *Shrinkage (statistics), a technique to improve an estimator *Shrinkage (slang) See also *Degrowth *Downsizing (other) *Human penis size *Miniaturization *Resizing (fiction) *Shrink (other) *Swelling (other) (opposite of shrinkage) {{Disambiguation ...
