domain, in physics: see magnetismmagnetism,
force of attraction or repulsion between various substances, especially those made of iron and certain other metals; ultimately it is due to the motion of electric charges.
..... Click the link for more information. .Domain (electricity and magnetism) A region in a solid within which elementary atomic or molecular magnetic or electric moments are uniformly aligned. Ferromagnetic domains are regions of parallel-aligned magnetic moments. Each domain may be thought of as a tiny magnet pointing in a certain direction. The relatively thin boundary region between two domains is called a domain wall. Within a wall the magnetic moments rotate from the direction of one of the domains to the direction in the adjacent domain. A ferromagnet generally consists of a large number of domains. For example, a sample of pure iron at room temperature contains many domains whose directions are distributed randomly, making the sample appear to be unmagnetized as a whole. Iron is called magnetically soft since the domain walls move easily if a magnetic field is applied. In a magnetically hard or permanent magnet material a net macroscopic magnetization is introduced by exposure to a large external magnetic field, but thereafter domain walls are difficult to either form or move, and the material retains its overall magnetization. Antiferromagnetic domains are regions of antiparallel-aligned magnetic moments. They are associated with the presence of grain boundaries, twinning, and other crystal inhomogeneities. Ferroelectric domains are electrical analogs of ferromagnetic domains. See Antiferromagnetism, Ferroelectrics, Ferromagnetism, Magnetic materials, Magnetization, Twinning (crystallography) Domain (1) Royal domain, hereditary land possessions of the king in the countries of Western and Central Europe in the Middle Ages. It included ancestral lands, fortresses, cities, forests, and pastures scattered in various areas of the country. It served as a fund for grants of land to the direct vassals of the king and also as the main source for the maintenance of the king and the royal court. The expansion of royal domains through the annexation of estates of large feudal lords was one of the means of strengthening royal power and eliminating feudal fragmentation. Dukes, counts, and other major feudal lords also had their own domains. (2) Seignorial domain, part of the patrimony (or temporarily held service lands) on which the feudal lord carried on an independent (domanial) economy, using the labor of feudally dependent peasant holders or landless workers. It included arable lands (situated, as a rule, in open fields along with peasant lands), fields, orchards, structures, livestock, and tools and equipment.
Domain in mathematics, an open connected set, that is, a set that satisfies the conditions (1) for any division of the set into two parts, at least one part contains a limit point of the other and (2) for each point in the set, some neighborhood of that point also belongs to the set. Thus, in the plane, the interior of a circle is a domain, but the set of interior points of two externally tangent circles, while open, is not a domain. A domain on a line is an open interval, either finite or infinite (seeINTERVAL AND SEGMENT). There is an infinite variety of domains in the plane. The concept of domain may be extended without change to any topological space. domain[dō′mān] (computer science) The set of all possible values contained in a particular field for every record of a file. The protected resources that are surrounded by the security perimeter of a distributed computer system. Also known as enclave; protected subnetwork. The final two or three letters of an Internet address, which specifies the highest subdivision; in the United States this is the type of organization, such as commercial, educational, or governmental, while outside the United States it is usually a country. (mathematics) For a function, the set of values of the independent variable. A nonempty open connected set in Euclidean space. Also known as open region; region. Abelian field (solid-state physics) A region in a solid within which elementary atomic or molecular magnetic or electric moments are uniformly arrayed. domain1. land governed by a ruler or government 2. a region having specific characteristics or containing certain types of plants or animals 3.

Biochem a structurally compact portion of a protein molecule domain (networking)A group of computers whose fully qualified domain names (FQDN) share a common suffix, the "domain name".

do·main (dō-mān'), 1. Homologous unit of approximately 110-120 amino acids, groups of which make up the light and heavy chains of the immunoglobulin molecule; each serves a specific function. The light chain has two domains, one in the variable region and one in the constant region of the chain; the heavy chain has four to five domains, depending on the class of immunoglobulin, one in the variable region and the remaining ones in the constant region. 2. A region of a protein having some distinctive physical feature or role. 3. An independently folded, globular structure composed of one section of a polypeptide chain. A domain may interact with another domain; it may be associated with a particular function. Domains can vary in size. [Fr. domaine, fr. L. dominium, property, dominion] domain (dō-mān′)n.

Patient discussion about domainQ. What other illnesses are similar to asthma? I am 45 years old. My doctor suspects I might have adult asthma but there has yet been a final diagnosis made. What other problems might this be?A. Before diagnosing someone as asthmatic, alternative possibilities should be considered. A clinician taking a history should check whether the patient is using any known bronchoconstrictors (substances that cause narrowing of the airways, e.g., certain anti-inflammatory agents or beta-blockers). Chronic obstructive pulmonary disease, which closely resembles asthma, is correlated with more exposure to cigarette smoke, an older patient, and decreased likelihood of family history of atopy. Your physician should examine these possibilities as well before diagnosing. More discussions about domainDomain
Related to Domain: Domain registrationDomainThe complete and absolute ownership of land. Also the real estate so owned. The inherent sovereign power claimed by the legislature of a state, of controlling private property for public uses, is termed the right of eminent domain. National domain is sometimes applied to the aggregate of the property owned directly by a nation. Public domain embraces all lands, the title to which is in the United States, including land occupied for the purposes of federal buildings, arsenals, dock-yards, and so on, and land of an agricultural or mineral character not yet granted to private owners. Sphere of influence. Range of control or rule; realm. DOMAIN. It signifies sometimes, dominion, territory governed - sometimes, possession, estate - and sometimes, land about the mansion house of a lord. By domain is also understood the right to dispose at our pleasure of what belongs to us.
2. A distinction, has been made between property and domain. The former is said to be that quality which is conceived to be in the thing itself, considered as belonging to such or such person, exclusively of all others. By the latter is understood that right which the owner has of disposing of the thing. Hence domain and property are said to be correlative terms; the one is the active right to dispose, the other a passive quality which follows the thing, and places it at the disposition of the owner. 3 Toull. n. 8 3. But this distinction is too subtle for practical use. Puff. Droit de la Nature et des Gens, loi 4, c. 4, Sec. 2. Vide 1 B1. Com. 105, 106; 1 Bouv.
