Die (integrated circuit)
A die in the context of integrated circuits is a small block of semiconducting material, on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs) through processes such as photolithography. The wafer is cut (“diced”) into many pieces, each containing one copy of the circuit. Each of these pieces is called a die.
There are three commonly used plural forms: dice, dies, and die.

Die (manufacturing)
A die is a specialized tool used in manufacturing industries to cut or shape material mostly using a press. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology.
Die forming
Forming dies are typically made by tool and die makers and put into production after mounting into a press. The die is a metal block that is used for forming materials like sheet metal and plastic. For the vacuum forming of plastic sheet only a single form is used, typically to form transparent plastic containers (called blister packs) for merchandise. Vacuum forming is considered a simple molding thermoforming process but uses the same principles as die forming. For the forming of sheet metal, such as automobile body parts, two parts may be used: one, called the punch, performs the stretching, bending, and/or blanking operation, while another part, called the die block, securely clamps the workpiece and provides similar stretching, bending, and/or blanking operation. The workpiece may pass through several stages using different tools or operations to obtain the final form. In the case of an automotive component there will usually be a shearing operation after the main forming is done and then additional crimping or rolling operations to ensure that all sharp edges are hidden and to add rigidity to the panel.
Goodyear welt
A Goodyear welt is a strip of leather, rubber, or plastic that runs along the perimeter of a shoe outsole. The machinery used for the process was invented in 1869 by Charles Goodyear, Jr., the son of Charles Goodyear. Goodyear construction is time-consuming but is considered the best method of shoe construction.
Construction
A Goodyear welt is stitched to the upper and a strip of canvas (known as "gemming") which is cemented to the insole of a shoe as an attach-point for the sole. The space enclosed by the welt is then filled with cork or some other filler material (usually either porous or perforated, for breathability), and the outsole is both cemented and stitched to the welt. This process of making shoes is referred to as Goodyear welt construction. Shoes with other types of construction may also have welts.
Process
The Goodyear welt process is a machine based alternative to the traditional handwelted method (c. 1500 AD) for the manufacture of men's shoes, taking its name from the inventor who devised the original machine to replace the earlier completely hand sewn method. The benefit of a shoe which is made using the Goodyear welt construction is that the shoe can be resoled repeatedly, giving the shoe a lifespan of years, sometimes even decades. Some claims towards added ventilation have been made as well but there are no proven studies comparing the breathability of different shoe construction methods.
Welt (band)
Welt is a punk rock band formed in Sacramento, California in 1993 by Jason Cooper, who has been the only constant member.
History
Welt signed to the Dr. Dream label, releasing the "Lame" single in 1994. The band's debut album, Better Days, was released in 1995.Kicked in the Teeth Again (1996) was seen as a progression. The band relocated to Orange County in 1998, releasing third album Broke Down the same year.
The band underwent several lineup changes prior to the late 1990s. Since then the band has been more stable, with Cooper joined by guitarists Tobe Bean and Todd Harper and drummer Marc Harrismendy. In 2000 the band signed with B.Y.O. Records.
Two of the band's tracks ("Get Lost" and "Broken") were used in the soundtrack of the film 21 (2000), and "The World is Mine" was used in the 2002 film The Skulls II.
In 2009, Cooper released the album The Shop Tapes under the name Jason Welt.

Timeline
STS (TV channel)
STS (abbr. СТС from Russian: Сеть Телевизионных Станций, Set' Televizionnykh Stantsiy, Network of televisions stations) is a commercial television station based in Moscow, Russia. It belongs to the CTC Media, a Delaware-registered, Moscow-based NASDAQ-traded (CTCM) company with a market capitalization exceeding US$4 billion. The company is co-owned by National Media Group (Russia), Itera (Russia) and Modern Times Group (Sweden).
History
STS was launched on 1 December 1996 and today is a leading entertainment network in Russia. Focusing on entertainment, STS broadcasts a mix between Russian productions and international programming of interest to its target audience, viewers aged 6–54, especially younger audiences.
Approximately 100 million people are within STS’s signal reach. In 2007, STS achieved an average audience share in its target demographic of 11,3%. STS network reaches approximately 87% of urban households. It ranks as the fourth most watched nationwide broadcaster in Russia overall.
STS-123
STS-123 was a Space Shuttle mission to the International Space Station (ISS) which was flown by Space Shuttle Endeavour. STS-123 was the 1J/A ISS assembly mission. The original launch target date was 14 February 2008 but after the delay of STS-122, the shuttle was launched on 11 March 2008. It was the twenty-fifth shuttle mission to visit the ISS, and delivered the first module of the Japanese laboratory, Japanese Experiment Module (Kibō), and the Canadian Special Purpose Dexterous Manipulator, (SPDM) Dextre robotics system to the station. The mission duration was 15 days and 18 hours, and it was the first mission to fully utilize the Station-to-Shuttle Power Transfer System (SSPTS), allowing space station power to augment the shuttle power systems. The mission set a record for a shuttle's longest stay at the ISS.
Crew
Mission payloads
STS-123 delivered the pressurized section of the Japanese Experiment Logistics Module (ELM-PS) as well as the Special Purpose Dexterous Manipulator (SPDM) to the International Space Station. The SPDM was delivered disassembled on a Spacelab Pallet (SLP) and assembled during three spacewalks once it was at the station.
