### definite man-made polyester:

Unsaturated polyester
* is cheap, epoxies can be expensive.
* provide the foundation for developing crosslinked polyesters.

Definite pair
* A pair set
* Most pairs make excellent parents and can be used to foster other species of parrotlet.
* Pair digit.
* Pairs are gathering.
* Pairs are monogamous and mate for life
  - for a single season but the pair bond extends only to the nesting area
  - monogamous, and both parents incubate the eggs, as well as feed and care for the young
  - poker hands
  - sets
  - small groups
  - sometimes cooperative when hunting during the breeding season
  - usually monogamous with rare instances of polygyny
  - when the resulting dice roll contains a pair of the same number
  - can form very tight bonding
  - encodes all sets of objects with two components
  - mate for life , and stay together year-round
  - nesting in boxes on poles have much higher nesting success than pairs using boxes on trees
  - often form a tight pair bonding
* Pairs sometimes hunt cooperatively, particularly for large prey items
  - together to flush, chase, and catch their prey
  - tend to form lasting bonds
* Some pairs exhibit nest site fidelity over successive breeding seasons
  - mate for more than one breeding season
  - remain together for life, or at least until one or the other dies
+ Common buzzard: Birds
  * Buzzards do not normally form flocks, but several may be seen together on migration or in good habitat. Pairs mate for life.

### definite pair:

Mate pair
* Most mate pairs are reliable landmarks-they stick together and remain the same distance apart.
* are the sequenced ends of inserts that actually make up the scaffolds.

Pair bonding
* includes stick presentation, bill clappering, close perching.
* is the rule in areas with low frog densities.
* takes place in spring among young geese, one or two years of age.
* varies wildly between different species of pipefish.

Pairs skating
* has jumps , and sometimes the man lifts the woman in the air.
+ Figure skating: Winter Olympic sports
  * In figure skating, sometimes women or men skate alone, or they skate in couples. Couples dancing includes 'pairs' and ice dancing. Pairs skating has jumps, and sometimes the man lifts the woman in the air. These things are not done in ice dancing. In ice dancing, the woman must be held in the man's arm. Another kind of figure skating is synchronized skating done in groups.

Twisted pair
* forms the backbone of local telephone infrastructure.
* is common in telephone wiring and is increasingly common in data networks
  - telephony applications and is increasingly common in data networks
  - the most common transmission medium for both analog and digital signals
* refers to the concentric twisting of two insulated conductors.

Definite prime
* Prime definite quantity
  - is adulthood
* Primes are an essential component of strong cryptographic systems
  - integers which have no non-trivial factors
  - useful in cryptography

### definite prime:

Prime number
* Most prime numbers are even.
* are a rich and ancient source of mathematical mystery
  - all the natural numbers with exactly two divisors
  - always 'coprime' to each other
  - more than any assigned multitude of prime numbers
  - of major interest in number theory
  - only divisible by themselves and one
  - positive integers
  - very important in mathematics and computer science
* belong to an exclusive world of intellectual conceptions.
* exist today.
* is prime
* serve as building blocks in the mathematics of whole numbers.
+ Coprime, Properties of Coprime: Mathematics
+ Prime number, What prime numbers are used for: Number theory
  * Prime numbers are very important in mathematics and computer science. Some real-world uses are given below. Very big prime numbers are hard to find, so most of the time, numbers that are probably prime are used.
