Corporation

A corporation is a company or group of people authorized to act as a single entity (legally a person) and recognized as such in law. Early incorporated entities were established by charter (i.e. by an ad hoc act granted by a monarch or passed by a parliament or legislature). Most jurisdictions now allow the creation of new corporations through registration.

Corporations come in many different types but are usually divided by the law of the jurisdiction where they are chartered into two kinds: by whether or not they can issue stock, or by whether or not they are for profit.

Where local law distinguishes corporations by ability to issue stock, corporations allowed to do so are referred to as "stock corporations", ownership of the corporation is through stock, and owners of stock are referred to as "stockholders." Corporations not allowed to issue stock are referred to as "non-stock" corporations, those who are considered the owners of the corporation are those who have obtained membership in the corporation, and are referred to as a "member" of the corporation.

Corporation (feudal Europe)

In feudal Europe, a corporation (from the Latin corpus, corporis a body) was an aggregation of business interests into a single legal body, entity or compact, usually with an explicit license from city, church, or national leaders. These functioned as effective monopolies for a particular good or labor.

The term "corporation" was used as late as the 18th century in England to refer to such ventures as the East India Company or the Hudson's Bay Company: commercial organizations that operated under royal patent to have exclusive rights to a particular area of trade. In the medieval town, however, corporations were a conglomeration of interests that existed either as a development from, or in competition with, guilds. The most notable corporations were in trade and banking.

The effects of a corporation were similar to a monopoly. On the one hand, the ability to have sole access to markets meant that the business was encouraged (e.g., the ability to be an exclusive trader provided an incentive to the East India Company to accept financial risks in exploration) and the negative effects of competition were avoided (to take the same example, exclusive patents cut down on merchants sponsoring piracy). Innovation was stifled, however, and prices were unregulated. (In the case of patent corporations, the town or monarch was ostensibly able to regulate prices by revoking the patent, but this rarely occurred.)

Net (textile)

Net or netting is any textile in which the yarns are fused, looped or knotted at their intersections, resulting in a fabric with open spaces between the yarns. Net has many uses, and come in different varieties. Depending on the type of yarn or filament that is used to make up the textile, its characteristics can vary from durable to not durable.

Uses

People use net for many different occupations. Netting is one of the key components to fishing in mass quantities. This textile is used because of its sturdy yet flexible origin, which can carry weight yet, still be lightweight and compactable. Fisherman use netting when trawling, because it is sturdy enough to carry large amounts of weight as fish are trapped, pulled, then lifted out of water. Oftentimes, the filaments that make up the yarn are coated with wax or plastic. This coating adds a waterproof component to the textile that provides even more reliability. Net is also used in medical practices to provide fabric insulation and wrapping under an industry standard sling. In the medical practice, netting provides cushion and protection, when used in layers, but still allows the skin to breathe under the fabric. Depending on what the netting is being used for, a different wax or plastic coating can be applied in order to cover the filaments that use up the yarn. Filaments can be made from synthetic or natural fibres, but that is all up to the manufacturer when deciphering what the textiles future entails. When netting is going to be exposed to water or heat often, manufacturers consider that and apply what best fits that textile.

Net (polyhedron)

In geometry the net of a polyhedron is an arrangement of edge-joined polygons in the plane which can be folded (along edges) to become the faces of the polyhedron. Polyhedral nets are a useful aid to the study of polyhedra and solid geometry in general, as they allow for physical models of polyhedra to be constructed from material such as thin cardboard.

An early instance of polyhedral nets appears in the works of Albrecht Dürer.

Existence and uniqueness

Many different nets can exist for a given polyhedron, depending on the choices of which edges are joined and which are separated. Conversely, a given net may fold into more than one different convex polyhedron, depending on the angles at which its edges are folded and the choice of which edges to glue together. If a net is given together with a pattern for gluing its edges together, such that each vertex of the resulting shape has positive angular defect and such that the sum of these defects is exactly 4π, then there necessarily exists exactly one polyhedron that can be folded from it; this is Alexandrov's uniqueness theorem. However, the polyhedron formed in this way may have different faces than the ones specified as part of the net: some of the net polygons may have folds across them, and some of the edges between net polygons may remain unfolded. Additionally, the same net may have multiple valid gluing patterns, leading to different folded polyhedra.

Bank (card game)

Bank, also known also as "Polish Bank" or "Russian Bank," is the name of a comparing card game. The game requires a standard 52-card deck and five or six players.

Rules

At the start of the game, each player contributes an arranged stake to the pool. The dealer gives three cards to each player and turns up another; if this is not lower than an eight (ace is lowest), the dealer continues turning up cards until such a card is exposed. The player on the dealer's left, without touching or looking at the three cards received, can bet the amount of the pool, or any part of it, that among those cards is one that is higher (of the same suit) than the turn-up. If the player wins, the player takes the amount from the pool; if the player loses, the player pays that amount to the pool. Each player does the same in turn, the dealer last. Whenever the pool is exhausted, a fresh stake is put into the pool. After a round is over the deal passes. No player may touch any cards received until making a bet; the penalty is a fine to the pool of twice the stake, and the loss of the right to bet during that round.

Ocean bank

An ocean bank, sometimes referred to as a fishing bank or simply bank, is a part of the sea which is shallow compared to its surrounding area, such as a shoal or the top of an underwater hill. Somewhat like continental slopes, ocean banks slopes can upwell as tidal and other flows intercept them, resulting sometimes in nutrient rich currents. Because of this, some large banks, such as Dogger Bank and the Grand Banks of Newfoundland, are among the richest fishing grounds in the world.

There are some banks that were reported in the 19th century by navigators, such as Wachusett Reef, whose existence is doubtful.

Types

Ocean banks may be of volcanic nature. Banks may be carbonate or terrigenous. In tropical areas some banks are submerged atolls. As they are not associated with any landmass, banks have no outside source of sediments. Carbonate banks are typically platforms, rising from the ocean depths, whereas terrigenous banks are elevated sedimentary deposits.

Seamounts, by contrast, are mountains, of volcanic origin, rising from the deep sea, and are steeper, and higher in comparison to the surrounding seabed. Examples are Pioneer and Guide Seamounts, west of the Farallon Islands. The Pioneer Seamount has a depth of 1,000 meters, In other cases, parts of a bank may reach above the water surface, thereby forming islands.
