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.

Pulling (TV series)

Pulling is a BBC comedy series, produced by Silver River Productions and broadcast on BBC Three, about three single female friends who live in Penge, south-east London. It was co-written by Sharon Horgan and Dennis Kelly and stars Horgan as Donna, Tanya Franks as Karen, Rebekah Staton as Louise and Cavan Clerkin as Karl. Pulling was the last comedy show developed by Harry Thompson before his death.

The first series of six episodes was first shown in 2006 on BBC Three, then repeated on BBC Two in early 2008. A second six-episode series of Pulling aired on BBC Three from 23 March to 27 April 2008 and a final one-hour episode aired on BBC Three on 17 May 2009.

In Australia, series one and two was first aired back-to-back on ABC2 each Thursday at 10pm from 5 March 2009 although the final one-hour episode is yet to be screened by the network. Repeats have been screening on rotation through UKTV.

In 2007, the series was BAFTA nominated for Best Situation Comedy while Horgan won a British Comedy Award for Best Comedy Entertainment Actress in 2008. In the same year, it was announced that Pulling had been cancelled by BBC Three.
