Nitride chloride. A chloride nitride is a mixed anion compound containing both chloride (Cl−) and nitride ions (N3−). Another name is metallochloronitrides. They are a subclass of halide nitrides or pnictide halides.

The group 4 element chloride nitrides can be intercalated by alkali metals that supply extra electrons, and other molecules such as from solvents like tetrahydrofuran, yielding layered substances that are superconductors. A superconductor transition temperature Tc of 25.5K has been achieved.

Production 
Nitride chlorides may be produced by heating metal nitrides with metal chlorides. The ammonolysis process heats a metal chloride with ammonia. A related method heats a metal or metal hydride with ammonium chloride. The nitrogen source could also be an azide or an amide.

Creeper (tool). A creeper is a low-profile tool used to help a person more easily slide in and out of confined spaces, such as the underside of a car, for performing inspection or maintenance. Other names for such devices include car creeper, garage creeper and mechanic creeper. They are built with a low profile to reduce the amount of added height above the ground, thereby providing as much clearance as possible for the person lying on it.

It is usually a wheeled platform constructed using a stiff frame and wheels. Some also have ergonomic shapes or cutouts for the arms and shoulders providing extra room to make it easier to work in the confined space. Other types of creepers include specially designed mats (creeper mats), and there are also various improvised solutions such as lying on cardboard. The alternative to using a creeper is often lying directly on the ground, which gives added clearance, but can make it more difficult to get in and out due to friction against the ground.

Some creepers have dual-uses, such as being able to be folded to make a chair or a stool, or for compact storage. Some also have the ability to recline the headrest somewhat while in the lying position.

Gig-mill. A gig-mill (gigging machine, napping machine) was a type of raising machine that used teasels to produce a nap on cloth. Examples of the results of gigging are woolen fabrics such as chinchilla, beaver cloth, and melton. The process involved gradual teasing of the surface to raise the nap. Spelling in some localities is "Gigg".

Gigging
Gigging was an old method of raising. As with flannelette, the fabric surface is treated with sharp teasels during gigging to elevate the surface fibers, providing hairiness and lustrous nap. The fabric gets a soft feel. Teasels from a plant, a thistle-like species, were once used to make it. These were fixed to a cylinder. Later, teasels were replaced by metallic wires similar to those used in carding machines.

Napped fabrics 

"Napping", "raising" and "gigging" are synonymous terms. Napping is the process of brushing for raising the nap. The raising method is used to draw out the ends of the fibers. Examples of napped fabrics include brushed tricot, and flannelette.

Nap
Nap in textiles refers to the raised surface.

JabberMask. JabberMask is an under-development wearable computer face mask that uses LED lights to allow its wearer to smile in a manner, despite wearing a mask. The mask was developed by game developer Tyler Glaiel. An early unnamed prototype version of the mask gained considerable attention online when revealed on Glaiel's personal Twitter account, and even WHO ended up listing it as a "COVID-19 innovation" on their website. Though he initially said he had no plans to sell it and recommended people making their own, the positive press led him to eventually take the project to Kickstarter where he was able to crowdfund over $70,000 to mass-produce it. The mask is powered by an Arduino computer.

List of Delta DM-19 launches. 

About the Delta DM-19 
The Thor-Delta, also known as Delta DM-19 or just Delta was an early American expendable launch system used for 12 orbital launches in the early 1960s. A derivative of the Thor-Able, it was a member of the Thor family of rockets, and the first member of the Delta family.

The first stage was a Thor missile in the DM-19 configuration. The second stage was the Delta, which had been derived from the earlier Able stage. An Altair solid rocket motor was used as a third stage.

The basic design of the original Vanguard upper stages, featuring a pressure-fed nitric acid/UDMH, regeneratively cooled engine, was kept in place, but with an improved AJ10-118 engine. More significantly, the Delta stage featured cold gas attitude control jets allowing it to be stabilized in orbit for restart and more precise burns.

The Thor-Delta was the first rocket to use the combination of a Thor missile and a Delta upper stage. This configuration was reused for many later rockets, and a derivative, the Delta II, remained in service until 2018.

The Thor-Delta launched a number of significant payloads, including the first communications satellite, Echo 1A; the first British satellite, Ariel 1; and the first active direct-relay communications satellite, Telstar 1. All 12 launches occurred from Cape Canaveral Air Force Station Launch Complex 17. The launch of Telstar 1 used pad B, while all other launches were from pad A. All launches were successful except the maiden flight, which failed to place Echo 1 into orbit due to a problem with the second stage.

Single Use Plastic Deathbed. The Single Use Plastic Deathbed is an art installation at Freedom Ghat on the bank of Ganga river near Laxman Jhula in Rishikesh, Uttarakhand, India. It features three funeral pyres made from single use plastic waste. The installation was opened in December 2020.

History
Climate activist Aakash Ranison organised six waste cleanup drives in various tourist places in Rishikesh with help of volunteers in September 2020. Some of the collected plastic waste was used to build the installation with support of the Rishikesh Municipal Corporation and local people to create the awareness regarding ill effects of single use plastic. It was opened on 20 December 2020 on the International Human Solidarity Day.

Installation

There are three funeral pyres measuring 8 feet long, 3 feet wide and 3 feet high. Each of these pyres is made of 26 kg of single use plastic, equivalent to the average amount of plastic waste generated by one Indian citizen annually. Each pyre contains a different common type of plastic waste: disposable bottles, disposable food packages and plastic containers respectively. There is a mirror in front of the pyres, placed so that the viewer can see their own reflection while looking at the pyres.

The Garbage Chronicles. The Garbage Chronicles - Being an Account of the Adventures of Tom Javik and Wizzy Malloy in the Faraway Land of Catapulted Garbage is a science fiction comedy novel written by Brian Herbert and Kevin J. Anderson, first published on January 1, 1985 by Berkley Books.

Plot summary 
In the consumer society of the future, in order to cope with economic problems, recycling and repairing is made illegal, and all damaged goods and garbage are launched into outer space. The protagonist gets a job of tracking criminals who collect garbage on another planet.

History
The author wrote that a dramatic scene in the novel originated in a part of his then unpublished satirical science fiction short story "Earth Games" which was set in an alien world where earthling prisoners were forced to take part in mortal competitions in hotrod fighter cars called "Road Rage", "based on an ancient Earth highway ritual". "Earth Games" was published a year later in his collection Dangerous Worlds.

Reception
Neil Gaiman reviewed The Garbage Chronicles for Imagine magazine, and stated that "one of the worst books I've read in years - it may have been meant to be funny, but I could well be wrong - and should be avoided as you would a rabid dog with a Cruise missile."

A reviewer noticed an insider joke: among the trash depicted on the book dust cover there is a catalog of the Andromeda Books, a sci-fi bookstore.
