Rationing is the controlled distribution of scarce resources, goods, or services, or an artificial restriction of demand. Rationing controls the size of the ration, which is one person's allotted portion of the resources being distributed on a particular day or at a particular time. Rationing in the United States was introduced in stages during ...
Cold War unit designations. Most AAFBUs were inactivated before the 1947 USAF was established, but some were redesignated Air Force base units (AF BU), e.g., base operating units on 26 September 1947 such as Brooks' 306th, Barksdale's 2621st, and Williams' 3010th. Although many base units were smaller than squadrons, some AF BUs included ...
Groupon, Inc. is an American global e-commerce marketplace connecting subscribers with local merchants by offering activities, travel, goods and services in 13 [ 2] countries.

Believed to be the first coupon ever, this ticket for a free glass of Coca-Cola was first distributed in 1888 to help promote the drink. By 1913, the company had redeemed 8.5 million tickets. [6] Coca-Cola's 1888-issued "free glass of" is the earliest documented coupon. [6] [7] Coupons were mailed to potential customers and placed in magazines ...
Unit prefixes are common base-10 or base-2 powers multiples and submultiples of units. While a base unit is one that has been explicitly so designated, [2] a derived unit is unit for a derived quantity, involving the combination of quantities with different units; [1] several SI derived units are specially named.
As part of the 2019 redefinition of SI base units, the Boltzmann constant is one of the seven "defining constants" that have been given exact definitions. They are used in various combinations to define the seven SI base units. The Boltzmann constant is defined to be exactly 1.380 649 × 10 −23 joules per kelvin. [1]
Zone 5 uses eight 2-digit codes (51–58) and two sets of 3-digit codes (50x, 59x) to serve South and Central America. Zone 6 uses seven 2-digit codes (60–66) and three sets of 3-digit codes (67x–69x) to serve Southeast Asia and Oceania. Zone 7 uses an integrated numbering plan; two digits (7x) determine the area served: Russia or Kazakhstan.
There are 7 base units and 22 derived units [1] (excluding compound units). These units are used both in science and in commerce. Two of the base SI units and 17 of the derived units are named after scientists. [2] 28 non-SI units are named after scientists. By this convention, their names are immortalised.
