In solid-state physics, heavy fermion materials are a specific type of intermetallic compound, containing elements with 4f or 5f electrons in unfilled electron bands.
 Electrons are one type of fermion, and when they are found in such materials, they are sometimes referred to as heavy electrons.
 Heavy fermion materials have a low-temperature specific heat whose linear term is up to 1000 times larger than the value expected from the free-electron theory.
 The properties of the heavy fermion compounds often derive from the partly filled f-orbitals of rare-earth or actinide ions, which behave like localized magnetic moments.
 The name "heavy fermion" comes from the fact that the fermion behaves as if it has an effective mass greater than its rest mass.
 In the case of electrons, below a characteristic temperature (typically 10 K), the conduction electrons in these metallic compounds behave as if they had an effective mass up to 1000 times the free-electron mass.
 This large effective mass is also reflected in a large contribution to the resistivity from electron-electron scattering via the Kadowaki Woods ratio.
 Heavy fermion behavior has been found in a broad variety of states including metallic, superconducting, insulating and magnetic states.
 Characteristic examples are CeCu, CeAl, CeCuSi, YbAl, UBe and UPt.
Type I hypersensitivity (or immediate hypersensitivity) is an allergic reaction provoked by reexposure to a specific type of antigen referred to as an allergen.
 Type I is not to be confused with type II, type III, or type IV hypersensitivities, nor is it to be confused with Type I Diabetes or Type I of any other disease or reaction.
Resist dyeing (resist-dyeing) is a traditional method of dyeing textiles with patterns.
 Methods are used to "resist" or prevent the dye from reaching all the cloth, thereby creating a pattern and ground.
 The most common forms use wax, some type of paste made from starch or mud, or a mechanical resist that manipulates the cloth such as tying or stitching.
 Another form of resist involves using a chemical agent in a specific type of dye that will repel another type of dye printed over the top.
 The best-known varieties today include tie-dye and batik.
Sorry!
 is a board game that is based on the ancient cross and circle game "Pachisi".
 Players try to travel around the board with their pieces faster than any other player.
 Originally manufactured by W.H. Storey & Co in England and now by Hasbro, "Sorry!"
 is marketed for two to four players, ages six through adult.
 The game title comes from the many ways in which a player can negate the progress of another, while issuing an apologetic "Sorry!"
A phytobezoar is a type of bezoar, or trapped mass in the gastrointestinal system, that consists of components of indigestible plant material, such as fibres, skins and seeds.
 While phytobezoars may be discovered incidentally on barium x-ray or endoscopic testing of the stomach, individuals with phytobezoars may develop symptoms: nausea, vomiting, gastric outlet obstruction, perforation, abdominal pain, and bleeding have been reported.
 Conditions that lead to decreased motility in the stomach (gastroparesis) and surgeries on the stomach (such as vagotomy or gastric bypass) are associated with the development of phytobezoars.
 A specific type of phytobezoar, termed a diospyrobezoar, is associated with ingestion of unripe persimmons, which contain a soluble tannin called shibuol that polymerizes into a coagulative cellulose-protein compound in the acid environment of the stomach, to form the bezoar.
 In addition to their presence in human stomachs, phytobezoars have been documented in the stomachs of slaughtered plant-eating animals.
A star war was a decisive conflict between rival polities of the Maya civilization during the first millennium AD.
 The term comes from a specific type of glyph used in the Maya script, which depicts a star showering the earth with liquid droplets, or a star over a shell.
 It represents a verb but its phonemic value and specific meaning have not yet been deciphered.
 The name "star war" was coined by the epigrapher Linda Schele to refer to the glyph, and by extension to the type of conflict that it indicates.
Anti-MAG Peripheral Neuropathy is a specific type of peripheral neuropathy in which the person’s own immune system attacks cells that are specific in maintaining a healthy nervous system.
 As these cells are destroyed by antibodies, the nerve cells in the surrounding region begin to lose function and create many problems in both sensory and motor function.
 Specifically, antibodies against myelin-associated glycoprotein (MAG) damage Schwann cells.
 While the disorder occurs in only 10% of those afflicted with peripheral neuropathy, people afflicted have symptoms such as muscle weakness, sensory problems, and other motor deficits usually starting in the form of a tremor of the hands or trouble walking.
 There are, however, multiple treatments that range from simple exercises in order to build strength to targeted drug treatments that have been shown to improve function in people with this type of peripheral neuropathy.
Neutrophil swarming is a specific type of neutrophil migration behaviour characterised by a high coordination between neutrophils, clustering of neutrophils to the inflammation site and signalling to other neutrophils further away.
 This specific type of migration rely on the production and secretion of LTB4 and on the use of integrins for neutrophil to stop at the cluster site.
Pancreatic elastase is a form of elastase that is produced in the acinar cells of the pancreas, initially produced as an inactive zymogen and later activated in the duodenum by trypsin.
 Elastases form a subfamily of serine proteases, characterized by a distinctive structure consisting of two beta barrel domains converging at the active site that hydrolyze amides and esters amongst many proteins in addition to elastin, a type of connective tissue that holds organs together.
 Pancreatic elastase 1 is a serine endopeptidase, a specific type of protease that has the amino acid serine at its active site.
 Although the recommended name is pancreatic elastase, it can also be referred to as elastase-1, pancreatopeptidase, PE, or serine elastase.
Barbarossa is a plasticine-shaping German-style board game for 3 to 6 players, designed by Klaus Teuber in and published in 1988 by Kosmos in German and by Rio Grande Games in English.
 "Barbarossa" won the 1988 Spiel des Jahres award.
