Delta (wasp)

Delta is an Old World genus of potter wasps with species predominantly distributed through tropical Africa and Asia. Some species are present in the Palearctic region, and a few have been introduced in the Nearctic and Neotropical regions. The members of this genus have a long metasomal petiole, like members of the genera Eumenes and Zeta.

Species

W.A.S.P.

W.A.S.P. is an American heavy metal band formed in 1982 by Blackie Lawless, who is the last remaining original member of the band. They emerged from the same Los Angeles scene that spawned Van Halen, Mötley Crüe, Dokken, Ratt, Quiet Riot, Guns N' Roses and others. The band's popularity peaked in the 1980s, yet they continue to record and tour, making them one of the most enduring of the West Coast heavy metal bands. W.A.S.P. gained notoriety for their shock rock themed image, lyrics and live performances. They have sold over 12 million copies of their albums.

The band was a prominent target in the mid-1980s of the Parents Music Resource Center (PMRC), an organization that pushed for warning labels on recorded music. The band immortalized its fight with the PMRC on the song "Harder, Faster" from their 1987 live album, Live...In the Raw. "I Wanna Be Somebody" was the most successful single from W.A.S.P.'s debut album and it was ranked at No. 84 in VH1's 100 Greatest Hard Rock Songs of All Time. Their most recent album, Golgotha, was released in 2015.

Dartford (Arnold's hometown) is the setting.

It is available on the Cinema 16: World Short Films and Cinema 16: European Short Films (US Special Edition) DVDs, and as a bonus feature on the Fish Tank DVD in the UK.

Plot summary

Zoe, rapidly descending a flight of stairs, baby in hand, and three other children in tow. Zoe gets into a physical altercation with the neighbour. Tensions remain high as the two women and their children shout at one another and hurl insults.

They all head home, with the children asking for chips. A man then pulls up in a car and is curious as to who the children are. Zoe tells him that they belong to a mate of hers and she is just looking after them. He asks her if she would like to go for a drink. Zoe agrees to meet him.

Wasp (novel)

Wasp is a 1957 science fiction novel by English author Eric Frank Russell. Terry Pratchett (author of the Discworld series of fantasy books) stated that he "can't imagine a funnier terrorists' handbook." Wasp is generally considered Russell's best novel.

The title of Wasp comes from the idea that the main character's actions and central purpose mimic that particular insect; just as something as small as a wasp can terrorise a much larger creature in control of a car to the point of causing a crash and killing the occupants, so the defeat of an enemy may be wrought via psychological and guerrilla warfare by a small, but deadly, protagonist in their midst.

Plot summary

Set in an unspecified time in the future, the plot centres on protagonist James Mowry and an inter-planetary war between humans (collectively referred to as "Terrans") and the Sirians (collectively referred to as the Sirian Empire, from Sirius). The war has been in effect for nearly a year as the story begins. The Terrans, while technologically more advanced in most respects to the Sirians, are outnumbered and out-gunned by a factor of twelve-to-one.

Delta IV

Delta IV is an expendable launch system in the Delta rocket family. The rocket's main components are designed by Boeing's Integrated Defense Systems division and built in the United Launch Alliance (ULA) facility in Decatur, Alabama. Final assembly is completed at the launch site by ULA. The rockets were designed to launch payloads into orbit for the United States Air Force Evolved Expendable Launch Vehicle (EELV) program and commercial satellite business. Delta IV rockets are available in five versions: Medium, Medium+ (4,2), Medium+ (5,2), Medium+ (5,4), and Heavy, to cover a range of payload size and weight. Delta IV was primarily designed to satisfy the needs of the U.S. military.

The rockets are assembled at the Horizontal Integration Facility for launches from SLC-37B at Cape Canaveral, and in a similar facility for launches from SLC-6 at Vandenberg Air Force Base.

History

The Delta IV entered the space launch market when global capacity was already much higher than demand. Furthermore, as an unproven design it has had difficulty finding a market in commercial launches, and the cost to launch a Delta IV is higher than that for competing vehicles. In 2003, Boeing pulled the Delta IV from the commercial market, citing low demand and high costs. In 2005, Boeing stated that it sought to return the Delta IV to commercial service.

Delta 0100

The Delta 0100 series, also Delta 100, 0300 or 300 series, was an American expendable launch system which conducted orbital launches between 1968 and 1972. It was a member of the Delta family of rockets, and the first to be designated using a four digit numerical code. Two variants were flown, individually designated Delta 0300 and Delta 0900.

The Long Tank Thor, a stretched version of the Thor missile, was used as the first stage of the Delta 0100 series. Castor-2 solid rocket boosters were attached to increase thrust at lift-off, three on the 0300 variant, and nine on the 0900. The second stage was a Delta F.

Five 0100 series rockets were launched, three using the 0300 configuration, and two in the 0900 configuration. All launches occurred from Space Launch Complex 2W at Vandenberg AFB. There was one failure, the launch of ITOS E on July 16, 1973. A hydraulic pump malfunction led to loss of pressure to the second stage attitude control thrusters, causing the launch vehicle to tumble out of control and break up in the atmosphere.

Delta-like 1

Delta-like protein 1 is a protein that in humans is encoded by the DLL1 gene.

Function

DLL1 is a human homolog of the Notch Delta ligand and is a member of the delta/serrate/jagged family. It plays a role in mediating cell fate decisions during hematopoiesis. It may play a role in cell-to-cell communication.

Interactions

Delta-like 1 has been shown to interact with NOTCH2
