**Generic top-level domains** (**gTLDs**) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last label of every fully qualified domain name. They are called generic for historic reasons; initially, they were contrasted with country-specific TLDs in RFC 920.

The core group of generic top-level domains consists of the `com`, `info`, `net`, and `org` domains. In addition, the domains `biz`, `name`, and `pro` are also considered *generic*; however, these are designated as *restricted*, because registrations within them require proof of eligibility within the guidelines set for each.

Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains `edu`, `gov`, `int`, and `mil` are now considered sponsored top-level domains, much like the *themed* top-level domains (e.g., `jobs`). The entire group of domains that do not have a geographic or country designation (see country-code top-level domain) is still often referred to by the term *generic* TLDs.

In mathematics, a **lattice** is one of the fundamental algebraic structures used in abstract algebra. It consists of a partially ordered set in which every two elements have a unique supremum (also called a least upper bound or join) and a unique infimum (also called a greatest lower bound or meet). An example is given by the natural numbers, partially ordered by divisibility, for which the unique supremum is the least common multiple and the unique infimum is the greatest common divisor.

Lattices can also be characterized as algebraic structures satisfying certain axiomatic identities. Since the two definitions are equivalent, lattice theory draws on both order theory and universal algebra. Semilattices include lattices, which in turn include Heyting and Boolean algebras. These "lattice-like" structures all admit order-theoretic as well as algebraic descriptions.

If (*L*, ≤) is a partially ordered set (poset), and *S*⊆*L* is an arbitrary subset, then an element *u*∈*L* is said to be an **upper bound** of *S* if
*s*≤*u* for each *s*∈*S*. A set may have many upper bounds, or none at all. An upper bound *u* of *S* is said to be its **least upper bound**, or **join**, or **supremum**, if *u*≤*x* for each upper bound *x* of *S*. A set need not have a least upper bound, but it cannot have more than one. Dually, *l*∈*L* is said to be a **lower bound** of *S* if *l*≤*s* for each *s*∈*S*. A lower bound *l* of *S* is said to be its **greatest lower bound**, or **meet**, or **infimum**, if *x*≤*l* for each lower bound *x* of *S*. A set may have many lower bounds, or none at all, but can have at most one greatest lower bound.

* Meet* is an early Australian television series which aired on ABC during 1957. The series consisted of interviews in a 15-minute time-slot, with a single person interviewed in each episode. It aired live in Melbourne, with telerecordings (also known as kinescope recordings) made of the broadcasts so it could be shown in Sydney. In Melbourne it aired on Mondays. Following the end of the series, it was followed up with an interview series titled

Those who were interviewed in the series included Anona Winn,Hal Gye, Samuel Wadhams,Alan Marshall,Ian Clunies-Ross, Myra Roper,John Bechervaise, among others.

A search of the National Archives of Australia website suggests that at least two of the episodes still exist despite the wiping of the era. These episodes are the interviews with Ian Clunies-Ross and Vance Palmer.

The **law of superposition** is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy. In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. This is important to stratigraphic dating, which assumes that the law of superposition holds true and that an object cannot be older than the materials of which it is composed. The law was first proposed in the 17th century by the Danish scientist Nicolas Steno.

Superposition in archaeology and especially in stratification use during excavation is slightly different as the processes involved in laying down archaeological strata are somewhat different from geological processes. Man made intrusions and activity in the archaeological record need not form chronologically from top to bottom or be deformed from the horizontal as natural strata are by equivalent processes. Some archaeological strata (often termed as contexts or layers) are created by undercutting previous strata. An example would be that the silt back-fill of an underground drain would form some time after the ground immediately above it. Other examples of non vertical superposition would be modifications to standing structures such as the creation of new doors and windows in a wall. Superposition in archaeology requires a degree of interpretation to correctly identify chronological sequences and in this sense superposition in archaeology is more dynamic and multi-dimensional.

In mathematics, especially in the area of algebra known as group theory, the **Fitting subgroup** *F* of a finite group *G*, named after Hans Fitting, is the unique largest normal nilpotent subgroup of *G*. Intuitively, it represents the smallest subgroup which "controls" the structure of *G* when *G* is solvable. When *G* is not solvable, a similar role is played by the **generalized Fitting subgroup** *F ^{*}*, which is generated by the Fitting subgroup and the

For an arbitrary (not necessarily finite) group *G*, the Fitting subgroup is defined to be the subgroup generated by the nilpotent normal subgroups of *G*. For infinite groups, the Fitting subgroup is not always nilpotent.

The remainder of this article deals exclusively with finite groups.

The nilpotency of the Fitting subgroup of a finite group is guaranteed by Fitting's theorem which says that the product of a finite collection of normal nilpotent subgroups of *G* is again a normal nilpotent subgroup. It may also be explicitly constructed as the product of the p-cores of *G* over all of the primes *p* dividing the order of *G*.

A **layer** is the deposition of molecules on a substrate or base (glass, ceramic, semiconductor, or plastic/bioplastic) .

High temperature substrates includes stainless steel and polyimide film (expensive) and PET (cheap).

A depth of less than one micrometre is generally called a thin film while a depth greater than one micrometre is called a coating.

A web is a flexible substrate.

**Tennis** is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to play the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.

Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as "**lawn tennis**". It had close connections both to various field ("lawn") games such as croquet and bowls as well as to the older racket sport of *real tennis*. During most of the 19th-century in fact, the term "tennis" referred to real tennis, not lawn tennis: for example, in Disraeli's novel *Sybil* (1845), Lord Eugene De Vere announces that he will "go down to Hampton Court and play tennis."

I love to smoke. I love to smoke and I love to eat red meat. I love to eat raw fucking red meat. Nothing I like better than sucking down a hot steaming cheese burger and a butt at the same time. I love to smoke. I love to eat red meat. I'll only eat red meat that comes from cows who smoke, ok!? Special cows they grow in Virginia with voice boxes in their necks. "[VB] Moo"

I tried eating vegetarian. I feel like a wimp going into a restaurant. "What do you want to eat sir? Brocolli?" Brocolli's a side dish, folks. Always was, always will be, ok? When they ask me what I want, I say, "What do you think I want!? This is America. I want a bowl of raw red meat right now. Forget about that. Bring me a live cow over to the table. I'll carve off what I want and ride the rest home! [Making riding noises]"

I gonna open up my own place. Open my own restaurant and get away from you people. I gonna open up a restaurant with two smoking sections; Ultra and Regular, ok? And we're not gonna have any tables or any chairs or any napkins. None of that pussy shit. Just a big wide open black space. And all we're gonna serve is raw meat, right on the bone! And only men are going to eat there, naked men, sitting around a big giant camp fire, and no men's room either. You have to piss, you mark your territory like a wolf! And if some guy has a heart attack from eating too much meat, fuck him, we throw him in the fire! More meat for the other meat-eaters! Yeah!
