Del, or nabla, is an operator used in mathematics, in particular, in vector calculus, as a vector differential operator, usually represented by the nabla symbol ∇. When applied to a function defined on a one-dimensional domain, it denotes its standard derivative as defined in calculus. When applied to a field (a function defined on a multi-dimensional domain), del may denote the gradient (locally steepest slope) of a scalar field (or sometimes of a vector field, as in the Navier–Stokes equations), the divergence of a vector field, or the curl (rotation) of a vector field, depending on the way it is applied.
Strictly speaking, del is not a specific operator, but rather a convenient mathematical notation for those three operators, that makes many equations easier to write and remember. The del symbol can be interpreted as a vector of partial derivative operators, and its three possible meanings—gradient, divergence, and curl—can be formally viewed as the product with a scalar, dot product, and cross product, respectively, of the del "operator" with the field. These formal products do not necessarily commute with other operators or products.
A deel (Mongolian: дээл [teːɮ]; Buryat: дэгэл) is an item of traditional clothing commonly worn since centuries ago among the Mongols and other nomadic tribes of Central Asia, including various Turkic peoples, and can be made from cotton, silk, wool, or brocade. The deel is still commonly worn by both men and women outside major towns, especially by herders. In urban areas, deels are mostly only worn by elderly people, or on festive occasions. The deel appears similar to a caftan or an old European folded tunic. Deels typically reach to below the wearer's knees and fan out at the bottom and are commonly blue, olive, or burgundy, though there are deels in a variety of other colors.
The deel looks like a large overcoat when not worn. Instead of buttoning together in the middle, the sides are pulled against the wearers body, the right flap close to the body with the left covering. On the right side of the wearer are typically 5 or 6 clasps to hold the top flap in place. There is one clasp below the armpit, three at the shoulder, and either one or two at the neckline.
Alpha Delphini (α Del, α Delphini) is a multiple star in the constellation Delphinus. It also has the name Sualocin, which was given to it as a practical joke by the astronomer Niccolò Cacciatore; the name is the Latinized version (Nicolaus) of his given name, spelled backwards.
In Chinese, 瓠瓜 (Hù Guā), meaning Good Gourd, refers to an asterism consisting of α Delphini, γ2 Delphini, δ Delphini, β Delphini and ζ Delphini. Consequently, α Delphini itself is known as 瓠瓜一 (Hù Guā yī, English: the First Star of Good Gourd.).
Alpha Delphini has seven components: A and G, a physical binary, and B, C, D, E, and F, which are optical binaries and have no physical association with A and G.
A business, also known as an enterprise, agency or a firm, is an entity involved in the provision of goods and/or services to consumers. Businesses are prevalent in capitalist economies, where most of them are privately owned and provide goods and services to customers in exchange for other goods, services, or money. Businesses may also be social not-for-profit enterprises or state-owned public enterprises targeted for specific social and economic objectives. A business owned by multiple individuals may be formed as an incorporated company or jointly organised as a partnership. Countries have different laws that may ascribe different rights to the various business entities.
Business can refer to a particular organization or to an entire market sector, e.g. "the music business". Compound forms such as agribusiness represent subsets of the word's broader meaning, which encompasses all activity by suppliers of goods and services. The goal is for sales to be more than expenditures resulting in a profit.
A business is an organization involved in the trade of goods, services, or both, with consumers.
Business may also refer to:
Business (Russian: Би́знес; Ukrainian: Бізнес) is a Ukrainian Russian-language weekly business newspaper published every Monday.
The newspaper was first published in Kiev in November 1992. The idea was put forward by Sergey Melnichuk. The motto of the publication was "Read! Think! Delaiah!" The first two years of Business was a collection of leaflets about buying and selling. Sergei Melnichuk directly supervised the release.
In 1994 he decided to broaden the focus to provide economic news and analysis material. That same year Konstantin Donin became editor in chief. Melnichuk tried to expand to three regions, issuing three regional newspapers: "Business-Donbass", "Business-Kharkov" and "Business-Crimea. All publications were issued in Russian.
During 1994–1995, the newspaper developed rapidly working with advertisers.
In 1996 the newspaper added a colored cover and raised ad rates. Profitability reached 300% and monthly advertising revenues reached $1.5 million.
