Unbundling Selling various component parts of a product
or service separately, usually at a price that reflects costs for only that
component of the product or service.

Unemployed Persons Persons 16
years and over who had no employment during the reference week, were available
for work, except for temporary illness, and had made specific efforts to find
employment sometime during the 4-week period ending with the reference week.
Persons who were waiting to be recalled to a job from which they had been laid
off need not have been looking for work to be classified as unemployed.

Uniform Freight Classification See UFC
Uninterruptible Power Supply See UPS
Unit Load Packages loaded on a pallet, in a crate or
any other way that enables them to be handled at one time as a unit.
Unit Train A train of a specified number of railcars, perhaps 100,
which remain as a unit for a designated destination or until a change in
routing is made.
UNIX The most popular operating system for host
computers on the Internet. One does not need to be a UNIX specialist to tap the
resources of the Internet, but it helps to know a few fundamental commands. Many
of the commands are similar to those in DOS.
UPS
Uninterruptible Power Supply. A
type of battery backup system designed to provide continuous power to critical
electrical loads.
Urban Runoff
Storm water from urban areas, which tends to contain heavy
concentrations of pollutants from vehicles and industry.
Use Tax A
tax levied on the use of tangible personal property.

USGS The National Mapping Program of the U.S.
Geological Survey (USGS) is the descendant of the Corps of Topographical
Engineers, formed in 1838 to map the western lands of the then conterminous
United States. The USGS took over responsibility for mapping the country in
1879 and has been the primary civilian mapping agency of the United States ever
since. The best known of today's USGS maps are the 1:24,000-scale topographic
maps, also known as 7.5-minute quadrangles. The USGS began mapping the country
at this scale after World War II and completed the program in the late 1980's.
More than 57,000 7.5-minute maps were made to cover the 48 conterminous States.
This is the only uniform map series that covers the entire area of the United
States in considerable detail. The USGS
today produces more than 80,000 different maps. These include the 7.5-minute
series, topographic maps at smaller scales, maps of U.S. possessions and
territories and of Antarctica, special maps of national parks and monuments,
and geologic and hydrologic maps. http://mcmcweb.er.usgs.gov/topomaps/

USTs Underground Storage Tanks. Storage tanks that have at least 10
percent (10%) of their storage capacity underground.
Var The unit of reactive power. For a two-wire
circuit, the product of the voltage times the current times the sine of the
angular phase difference by which the voltage leads or lags the current. Vars
and watts combine in a quadrature relationship to form voltamperes.
Ventilated
Container A
container designed with openings in the side and/or end walls to permit the
ingress of outside air when the doors are closed.
Vocational
Schools Schools in
which technical
preparation is provided in career fields such as engineering technology, a
mechanical, industrial, or practical art or trade, business or health
occupations. See Tech Prep
Voltage The electric pressure of a circuit, measured
in volts. Usually a nominal rating, based on the maximum normal effective
difference of potential between any two conductors of the circuit.
Volt The unit of electromotive force or electric
pressure analogous to water pressure in pounds per square inch. It is the
electromotive force, which, if steadily applied to a circuit having a
resistance of one ohm, will produce a current of one ampere.
Voltage of a Circuit The electric pressure of a circuit in an
electric system measured in volts. It is generally a nominal rating based on
the maximum normal effective difference of potential between any two conductors
of the circuit.
Voltage Regulator An electrical device that regulates voltage
on distribution lines. It automatically raises and lowers the voltage to
maintain required voltage levels for service.
Voltampere (VA) The
basic unit of Apparent Power. The voltamperes of an electric circuit is the
mathematical product of the volts and amperes of the circuit. The practical
unit of Apparent Power is Kilovoltampere (kVA), which is 1,000 voltamperes.
