Farrier
A farrier is a specialist in equine hoof care, including the trimming and balancing of horses' hooves and the placing of shoes on their hooves, if necessary. A farrier combines some blacksmith's skills (fabricating, adapting, and adjusting metal shoes) with some veterinarian's skills (knowledge of the anatomy and physiology of the lower limb) to care for horses' feet. History While the practice of putting protective hoof coverings on horses dates back to the first century, evidence suggests that the practice of nailing iron shoes into a horse’s hoof is a much later invention. One of the first archaeological discoveries of an iron horseshoe was found in the tomb of Merovingian king Childeric I, who reigned from 458-481/82. The discovery was made by Adrien Quinquin in 1653, and the findings were written about by Jean-Jacques Chifflet in 1655. Chifflet wrote that the iron horseshoe was so rusted that it fell apart as he attempted to clean it. He did, however, make an ...

Horseshoe
A horseshoe is a fabricated product designed to protect a horse hoof from wear. Shoes are attached on the palmar surface (ground side) of the hooves, usually nailed through the insensitive hoof wall that is anatomically akin to the human toenail, although much larger and thicker. However, there are also cases where shoes are glued. Horseshoes are available in a wide variety of materials and styles, developed for different types of horse and for the work they do. The most common materials are steel and aluminium, but specialized shoes may include use of rubber, plastic, magnesium, titanium, or copper.Price, Steven D. (ed.) ''The Whole Horse Catalog: Revised and Updated'' New York:Fireside 1998 , pp. 84–87. Steel tends to be preferred in sports in which a strong, long-wearing shoe is needed, such as polo, eventing, show jumping, and western riding events. Aluminium shoes are lighter, making them common in horse racing where a lighter shoe is desired, and often faci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ferrier Estate
The Ferrier Estate was a large housing estate located in Kidbrooke, Greenwich, south London. Built as social housing between 1968 and 1972, it was demolished as part of the Kidbrooke Vision scheme between 2009 and 2012 and replaced with housing and retail space known as Kidbrooke Village. The estate was located to the south of Kidbrooke railway station and the A2 Rochester Way and to the north of the A20, to the east of Blackheath and to the west of the border of Eltham. History The estate was constructed by the Greater London Council between 1968 and 1972 to the east of Blackheath on brownfield land from the former RAF Kidbrooke base. It was built on two sites. Site A was approved in 1967 with construction of five 12-storey towers (Clegg, Crozier, Goldmark, Leclair and Sala Houses) commencing one year later. Site B was approved in 1970 with construction of six 12-storey towers (Felton, Ronald, Stainer, Standish, Sterling and Wixom Houses) commencing the same year. A typi ...

Ferrier Peninsula
Ferrier Peninsula is a narrow peninsula, long, forming the eastern end of Laurie Island in the South Orkney Islands of Antarctica. It was roughly charted in 1823 by a British sealing expedition under James Weddell. It was surveyed in 1903 by the Scottish National Antarctic Expedition under William Speirs Bruce, who named it for his secretary J.G. Ferrier, who was also manager in Scotland of the expedition. Important Bird Area The peninsula, along with the nearby Graptolite Island, has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a large breeding colony of about 91,000 pairs of Adélie penguins as well as 14,000 pairs of chinstrap penguins. Gentoo penguin The gentoo penguin ( ) (''Pygoscelis papua'') is a penguin species (or possibly a species complex) in the genus '' Pygoscelis'', most closely related to the Adélie penguin (''P. adeliae'') and the chinstrap penguin (''P. antarcticus'').

Ferrier Carbocyclization
The Ferrier carbocyclization (or Ferrier II reaction) is an organic reaction that was first reported by the carbohydrate chemist Robert J. Ferrier in 1979. It is a metal-mediated rearrangement of enol ether pyrans to cyclohexanones. Typically, this reaction is catalyzed by mercury salts, specifically mercury(II) chloride. Several reviews have been published. Reaction mechanism Ferrier proposed the following reaction mechanism: In this mechanism, the terminal olefin undergoes hydroxymercuration to produce the first intermediate, compound 2, a hemiacetal. Next, methanol is lost and the dicarbonyl compound cyclizes through an attack on the electrophilic aldehyde to form the carbocycle as the product. A downside to this reaction is that the loss of CH3OH at the anomeric position (carbon-1) results in a mixture of α- and β-anomers. The reaction also works for substituted alkenes (e. g. having an -O Ac group on the terminal alkene). Ferrier also reported that the final pro ...

Ferrier Rearrangement
The Ferrier rearrangement is an organic reaction that involves a nucleophilic substitution reaction combined with an allylic shift in a glycal (a 2,3- unsaturated glycoside). It was discovered by the carbohydrate chemist Robert J. Ferrier. Mechanism In the first step, a delocalized allyloxocarbenium ion (2) is formed, typically with the aid of a Lewis acid like indium(III) chloride or boron trifluoride. This ion reacts in situ with an alcohol, yielding a mixture of the α (3) and β (4) anomers of the 2-glycoside, with the double bond shifted to position 3,4. Examples Modifications Forming of C-glycosides By replacing the alcohol with a silane, C-glycosides can be formed. With triethylsilane (R'=H), the reaction yields a 2,3-unsaturated deoxy sugar. Nitrogen analogue An analogous reaction with nitrogen as the heteroatom was described in 1984 for the synthesis of the antibiotic An antibiotic is a type of antimicrobial substance active against bacteria. It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kathleen Ferrier Award
The Kathleen Ferrier Award is a prestigious contest for Opera singers held each April in London, England. The first competition was held in 1956. According to the '' Telegraph'', the competition has a record of "spotting winners". Originally conceived to offer a prize equivalent to a year's tuition plus support, the competition now offers a first prize of £10,000, a second prize of £5,000 and a Song Prize of £2,500. The competition is open to singers of any nationality who have completed at least one year of study at a UK conservatoire or with a recognised vocal coach in the UK. They must be under 29 years of age at the time of the final audition. There is also an MBF Accompanist's prize, provided in 2005 by Arthur & Gwyneth Harrison. Pianists competing for the accompanist's award must also be under 29. The first recipient of the award was British-born Barbara Anne Robinson. The Kathleen Ferrier Memorial Scholarship Fund, which funds the award, was founded in 1953 in memor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
