Wood ash

Wood ash is the residue powder left after the combustion of wood, such as burning wood in a home fireplace or an industrial power plant. It is used traditionally by gardeners as a good source of potash for domestic gardens or any garden.

Composition

Variability in assessment

Many studies have been conducted regarding the chemical composition of wood ash, with widely varying results. Some quote calcium carbonate (CaCO₃) as the major constituent, others find no carbonate at all, but calcium oxide (CaO) instead. Some show as much as twelve percent iron oxide while others show none, though iron oxide is often introduced through contamination with soil. A comprehensive set of analyses of wood ash composition from many tree species has been carried out by Emil Wolff, among others.

There are several factors which have a major impact on the composition:

Wood

Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants.

It has been used for thousands of years for both fuel and as a construction material. It is an organic material, a natural composite of cellulose fibers (which are strong in tension) embedded in a matrix of lignin which resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.

The Earth contains about 434 billion cubic meters of growing stock forest, 47% of which is commercial. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy. In 1991, approximately 3.5 cubic kilometers of wood were harvested. Dominant uses were for furniture and building construction.

British Sea Power

British Sea Power are an indie rock band based in Brighton, East Sussex, England, although three of the band members originally come from Natland (near Kendal), Cumbria, England. The wide-ranging nature of their material has led critics to liken their sound to a variety of groups, from The Cure and Joy Division to the Pixies and Arcade Fire. The band are famed for their live performances, the unusual lyrical content of their songs and the adventurous choice of locations for some of their shows. British Sea Power's members are Jan Scott Wilkinson (vocals, guitar), Martin Noble (guitar), Neil Hamilton Wilkinson (bass guitar, vocals, guitar), Matthew Wood; (drums), Phil Sumner (cornet, keyboards) and Abi Fry (viola).

History

Early years and The Decline of British Sea Power

British Sea Power's Yan and Hamilton are brothers and were school friends with Wood in Kendal. They were in a number of bands together while at school, but after finishing his exams Yan moved to study at the University of Reading, where he met guitarist Noble, who was originally from Bury, Greater Manchester. A few years later, Hamilton and Wood joined them and formed a band.

Wood (Kent cricketer, 1828)

Wood (first name and dates unknown) was an English cricketer who made two known appearances in first-class matches for Kent from 1828 to 1829.

Ash (deity)

Ash was the ancient Egyptian god of oases, as well as the vineyards of the western Nile Delta and thus was viewed as a benign deity. Flinders Petrie in his 1923 expedition to the Saqqara (also spelt Sakkara) found several references to Ash in Old Kingdom wine jar seals: "I am refreshed by this Ash" was a common inscription.

In particular, he was identified by the Ancient Egyptians as the god of the Libu and Tinhu tribes, known as the "people of the oasis". Consequently Ash was known as the "lord of Libya", the western border areas occupied by the Libu and Tinhu tribes, corresponds roughly with the area of modern Libya. It is also possible that he was worshiped in Ombos, as their original chief deity.

In Egyptian mythology, as god of the oases, Ash was associated with Set, who was originally god of the desert, and was seen as protector of the Sahara. The first known reference to Ash dates to the Protodynastic Period, but by the late 2nd Dynasty, his importance had grown, and he was seen as protector of the royal estates, since the related god Set, in Lower Egypt, was regarded as the patron deity of royalty itself. Ash's importance was such that he was mentioned even until the 26th Dynasty.

Ash (Alien)

Ash is a fictional character in the movie Alien, who was portrayed by actor Ian Holm, who, although known in the U.K. as a stage actor, was at the time unknown to American audiences. Ash serves as the secondary antagonist of the first film. The character is the science officer of the Nostromo, who breaks quarantine by allowing Kane, a member of the crew, back on board after he has been infected by an alien life form. It is later discovered that Ash is not human at all, as he appears, but is in fact a Hyperdyne Systems 120-A/2android, who is acting upon secret orders to bring back the alien lifeform and to consider the crew "expendable".

Character development

At the beginning of the film, Ash is depicted as quiet and logical, greatly adherent to company regulations. However, he breaks quarantine protocol (disobeying Ripley, the ship's ranking officer, in the process) and allows the infected Kane aboard the ship, seemingly out of compassion, and is later seen marveling at the creature attached to him. At one point, Ash assaults Ripley, attempting to kill her by forcing a rolled-up pornographic magazine down her throat. But it is Ash himself who is killed, as two other crew members arrive and rescue Ripley. He is struck over the head twice with a canister, the first time causing him to malfunction and the second decapitating him. When even that fails to kill him, he's electrocuted with a cattle prod.
