`
`unit
`
`uniform topology Mathematics. given a uniformity F on a topological
`space X, the topology whose open sets are the subsets U of X with the
`property that there is a set V in F such that the set {y : (x,y) E V for
`some x a U} is a subset of U. If a uniform topology exists for X, then X
`is said to be a uniform space.
`unijunction transistor Electronics. a three-terminal transistor con-
`taining an emitter and two bases, and possessing negative-resistance
`characteristics; used mainly in switching circuits.
`unilateral Science. of or relating to only one side.
`unilateral anesthesia see HEMIANESTHESIA.
`unilateral conductivity Electronics. the theoretical property of a cir-
`cuit element to conduct electrical current in one direction only; in prac-
`tice, even the best diode allows some reverse current to flow.
`unilateral hermaphroditism Zoology, the presence of gonadal tissue
`typical of both sexes on one side, and of an ovary or testis on the other.
`unilateralization Electronics. a technique similar to neutralization in
`which both the resistive and reactive components of feedback in a de-
`vice are completely neutralized by external feedback to prevent unde-
`sired oscillations; the result is a device that effectively has no feedback.
`unilateral surface Mathematics. a nonorientable two-dimensional
`manifold (e.g., the Mobius strip or Klein bottle) that has only one side.
`unilateral tolerance method Design Engineering, a tolerance
`methodology applied to dimensioning where the tolerance is either a
`plus or a minus from the stated dimension; the dimension is the size or
`location nearest the critical condition of the material and the tolerance is
`either a plus or minus, whichever allows variation away from the critical
`point.
`unilateral transducer see UNIDIRECTIONAL TRANSDUCER.
`unilineal descent Anthropology, a practice in which one is related
`through a group of kin solely on the basis of one sex or the other.

`matid has only a single DNA duplex, which reaches from one end of the
`chromatid to the other.
`uninhibited neurogenic bladder Medicine, a dysfunction of the
`bladder due to a lesion in the region of the upper motor neurons, marked
`by urgency and frequent involuntary voiding.
`unintentional radiation exploitation Military Science. the opera-
`tional use of non-information-bearing elements of electromagnetic en-
`ergy unintentionally emanated by targets of interest.
`uninterruptible power system Electricity, a power system that pro-
`vides protection against primary power failure and variations in power-
`line frequency and voltage; commonly consists of a storage battery,
`battery charger, solid-state inverter, and solid-state switching circuit, as
`applied in computer systems; it may be used on-line between power line
`and load to provide voltage regulation and suppressed transients, or off-
`line and switched in only when utility power fails. Also, uninterrupt-
`ible power source or supply.
`union the process of uniting, or something that unites; specific uses in-
`clude: Surgery. the process of healing; the adhesion or joining of struc-
`tures or tissues, such as the edges of a wound or interfaces of a fractured
`bone. Mechanical Devices, any of a number of devices used to connect
`machine pipes and other parts. Design Engineering, a flanged or
`screwed pipe coupling around the outside of a joint, usually in the form
`of a ring fitting. Computer Programming. 1. the logical OR of two
`propositions resulting in a True value if one of the propositions is True.
`2. the joining of two or more files or other objects. 3. a set union formed
`from two sets of data. Mathematics. 1. a binary set operation; denoted
`and read "union," "join," or "cup." The union A u B of two sets A and B
`is the set of all objects that are elements of at least one of A and B. 2. the
`union U of a collection I; ) of sets is the set having the following
`properties: (a) if x is an element of Xa for some a, then x is an element
`of U; and (b) if x is an element of U, then xis an element of Xa for some
`a. Also called a join or sum; often denoted uja, or similar notation. 3.
`the union U = G1 lJ G2 of two graphs G 1 and G2 is a graph with V(U) =
`V(G 1) u V(G2) such that two vertices are joined by an edge in at least
`one Gi.
`union dyeing Textiles, the process of dyeing fabrics made from more
`than one yarn type in one bath to produce either a uniform shade or a
`mottled effect caused by the different dyeing properties of the fibers.
`
`union fabric Textiles. a fabric made from more than one fiber type, es-
`pecially fabric made with a cotton warp and a wool filling.
`Unionidae Invertebrate Zoology, a large family of freshwater mussels,
`bivalve mollusks in the subclass Eulamellibranchia; the outer shell sur-
`face is rough and brown or black; the inner surface is pearly and used
`for buttons; larvae are fish ectoparasites.
`union joint Mechanical Devices, a threaded-pipe coupling used to con-
`nect two threaded pipes, which allows for disconnection without the
`need to rotate other pipe lengths.
`union of languages Computer Science. a language whose sentences
`are members of any of its component languages.
`unipara Medicine, a female who has had one pregnancy that resulted in
`a viable fetus, regardless of whether the infant was alive at birth, and re-
`gardless of whether it was a single or multiple birth.
`uniparental inheritance Genetics. a form of inheritance in which the
`offspring possess the phenotype of only one parent.
`unipolar Electricity, having a single pole or polarity or direction.
`Anatomy. of a nerve cell or other structure, having but a single pole or
`process. Psychology, describing a mood disorder in which only depres-
`sive episodes occur.

`protozoans in the order Myxosporida.
`unipolar transistor Electronics. 1. a transistor in which the main con-
`duction path is through P-type or N-type material, but not both, and
`charge carriers are of only one polarity. 2. see FIELD-El+bCT TRANSISTOR.

`unipole Electromagnetism. a hypothetical antenna that receives or
`transmits uniformly in all directions.
`uniport Biochemistry. the transmembrane movement of one kind of so-
`lute by a carrier not linked to another solute transport across the same
`membrane.

`unipotential electrostatic lens Electronics. an electrostatic lens hav-
`ing three apertures, with the same voltage difference between the central
`aperture and each of the outer apertures.
`unique DNA Molecular Biology. any sequence of nucleotides in DNA
`that occurs only one time in a genome.
`unique factorization domain Mathematics. an integral domain in
`which: (a) every nonzero nonunit element can be written as the product
`of a finite number of irreducible elements or factors; (b) any two such
`factorizations are composed of exactly the same number of' f lactors; and
`(c) the factors in any factorization can be permuted so that correspond-
`ing factors are associates of one another.
`unique factorization theorem Mathematics. a theorem stating that
`any positive integer can factored in exactly one way; follows from the
`fact that the integers form a unique factorization domain.

`standard. 2. relating to the quantity of one. 3. any type of quantity that
`qualifies a physical measurement, such as a velocity measurement,
`which may be qualified by cm/sec, km/hr, and so on. Engineering, any
`device that can operate independently, such as a radio receiver or an os-
`cilloscope. Military Science. 1. any military organization that is struc-
`tured according to competent authority, especially one that is part of a
`larger organization. 2. the organizational title of a subdivision of a task
`force group. Industrial Engineering. see UNIT OF ISSUE. Mathematics. 1.
`the multiplicative identity of a ring, field, etc. The phrases "ring with
`unit" or "ring with identity" are commonly used. Also, unit element,
`unity. 2. an element of a ring that has both a left and right multiplica-
`tive inverse. 3. having length or norm equal to 1. For example, a unit
`vector is a vector of length one. A unit binormal (normal, tangent) is a
`unit vector in the same direction as a given binormal (resp. normal, tan-
`gent) vector. The unit interval is the interval (0, 1) or [0, 1]. 4. centered
`at the origin and having radius 1. For example, the unit circle and unit
`n-sphere are the circle of radius 1 and the sphere of radius 1 centered at
`the origin in the plane and in n-space, respectively. The unit ball is the
`(open) interior of the unit circle or unit n-sphere; sometimes the unit ball
`is defined to be the (closed) union of the unit sphere and its interior.
