Last

A last is a mechanical form that has a shape similar to that of a human foot. It is used by shoemakers and cordwainers in the manufacture and repair of shoes. Lasts typically come in pairs and have been made from various materials, including hardwoods, cast iron, and high-density plastics.

Production

Lasts come in many styles and sizes, depending on the exact job they are designed for. Common variations include simple one-size lasts used for repairing soles and heels, durable lasts used in modern mass production, and custom-made lasts used in the making of bespoke footwear. Though a last is made approximately in the shape of a human foot, the precise shape is tailored to the kind of footwear being made. For example, a boot last would be designed to hug the instep for a close fit. Modern last shapes are typically designed using dedicated computer-aided design software.

Historically, lasts were typically made from hardwoods and cast iron because these materials retain their shape, even when in contact with wet materials (like leather) and subjected to the mechanical stresses of stretching and shaping shoes on them. Today, wooden lasts are generally used only for bespoke shoemaking, particularly in Europe and North America.

Last (Uverworld album)

LAST is the 5th full album released by Japanese band Uverworld as well as the follow-up to their fourth album, Awakeve. It was released on April 14, 2010. A limited pressing of the album was also released on the same day which includes a DVD containing music videos of 99/100 Damashi no Tetsu (99/100騙しの哲?), Go-On and Kanashimi wa Kitto (哀しみはきっと?) as well as a video of the filming process for their 3 music videos and a bonus clip "Special Track 09.12.25: Turn Around with Gold" which is a Gold special video.

The album was one of the highly anticipated album and was ranked #2 at the Ninki Chart and was charted at #2 for Oricon Weekly Ranking.

The title means the present time's highest, newest and the ultimate album.

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.

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.

Wave

In physics, a wave is an oscillation accompanied by a transfer of energy that travels through space or mass. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission medium—that is, with little or no associated mass transport. Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations.

There are two main types of waves. Mechanical waves propagate through a medium, and the substance of this medium is deformed. The deformation reverses itself owing to restoring forces resulting from its deformation. For example, sound waves propagate via air molecules colliding with their neighbors. When air molecules collide, they also bounce away from each other (a restoring force). This keeps the molecules from continuing to travel in the direction of the wave.

The second main type of wave, electromagnetic waves, do not require a medium. Instead, they consist of periodic oscillations of electrical and magnetic fields originally generated by charged particles, and can therefore travel through a vacuum. These types of waves vary in wavelength, and include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
