Del
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.
Deel (clothing)
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.
Description
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
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.).
Properties
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.

Springtime!
Springtime! is a boutique entertainment company established in the UK in 1977 and based in the United States since 1983.

Record company
The record division of Springtime! was launched in 1981 as a label distributed in the UK by Island Records and in the US/Canada by Island/Warner Bros. Records.
The label is primarily focused on both newly recorded and historic comedy material. It has distributed recordings by the Portsmouth Sinfonia, alternative comedians such as Alexei Sayle,Rik Mayall, Ade Edmondson, Nigel Planer, Peter Richardson and French and Saunders of The Comic Strip, the historic Private Eye recordings. Springtime recorded and released Alexei Sayle's first album Cak! in 1982. 'The label's most successful humour release has been the comedy album of Amnesty International's, 1981 benefit show The Secret Policeman's Other Ball which featured John Cleese and Graham Chapman of Monty Python, Rowan Atkinson, Barry Humphries, Billy Connolly, Jasper Carrott, John Bird, John Fortune, Tim Brooke-Taylor, Griff Rhys Jones, Alexei Sayle and Neil Innes.
Springtime (painting)
Springtime is an 1872 painting by Claude Monet. It depicts his first wife, Camille Doncieux, seated serenely beneath a canopy of lilacs. The painting is presently held by the Walters Art Museum.
History
In this painting entitled Springtime, Claude Monet uses his first wife, Camille Doncieux, as the model. Camille and Claude Monet were married in 1870, before this time she had been his mistress and served as a model for Monet's figurative paintings of the 1860s and 1870s. It is said that Camille possessed unusual talent as a model and was also used by Auguste Renoir and Édouard Manet.
Late in the year 1871, Monet and his family settled in Argenteuil, a village Northwest of Paris. The village was a popular resort for urban pleasure-seekers. Colleagues of Monet frequently joined him and the village became associated with Impressionism. In the spring of 1872, Monet painted a number of canvases in his garden, often showing Camille and Alfred Sisley's companion, Adélaïde-Eugénie Lescouezec.
