Commander Of The Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organisations, and public service outside the civil service. It was established on 4 June 1917 by King George V and comprises five classes across both civil and military divisions, the most senior two of which make the recipient either a knight if male or dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order. Recommendations for appointments to the Order of the British Empire were originally made on the nomination of the United Kingdom, the self-governing Dominions of the Empire (later Commonwealth) and the Viceroy of India. Nominations continue today from Commonwealth countries that participate in recommending British honours. Most Commonwealth countries ceased recommendations for appointments to the Order of the British Empire when they cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biographical Memoirs Of Fellows Of The Royal Society
The ''Biographical Memoirs of Fellows of the Royal Society'' is an academic journal on the history of science published annually by the Royal Society. It publishes obituaries of Fellows of the Royal Society. It was established in 1932 as ''Obituary Notices of Fellows of the Royal Society'' and obtained its current title in 1955, with volume numbering restarting at 1. Prior to 1932, obituaries were published in the ''Proceedings of the Royal Society''. The memoirs are a significant historical record and most include a full bibliography of works by the subjects. The memoirs are often written by a scientist of the next generation, often one of the subject's own former students, or a close colleague. In many cases the author is also a Fellow. Notable biographies published in this journal include Albert Einstein, Alan Turing, Bertrand Russell, Claude Shannon, Clement Attlee, Ernst Mayr, and Erwin Schrödinger. Each year around 40 to 50 memoirs of deceased Fellows of the Royal Soci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Geological Society Of Cornwall
The Royal Geological Society of Cornwall is a geological society based in Penzance, Cornwall in the United Kingdom. It was founded in 1814 to promote the study of the geology of Cornwall, and is the second oldest geological society in the world, after the Geological Society of London which was founded in 1807. History The first President of the society was Davies Gilbert, the first Secretary John Ayrton Paris, and other notable members include Humphry Davy (some of whose papers are held by the Society), and William Gregor, who discovered titanium. The society's first premises was a house in North Parade, Penzance and in 1853 the Borough of Penzance put forward plans for a new public building on the west side of Penzance. It was planned to have the Borough offices, county court and police station in the east wing, the two floors of the west wing housing the RGSC's museum and a public hall between the two run by a public company. The foundation stone was laid on 27 April 1864, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tarbuttite
Tarbuttite is a rare phosphate mineral with formula Zn2(PO4)(OH). It was discovered in 1907 in what is now Zambia and named for Percy Tarbutt. Description and habit Tarbuttite is white, yellow, red, green, brown, or colorless; in transmitted light it is colorless. Traces of copper cause green coloring, while iron hydroxides cause the other colors. Colorless crystals tend to be transparent while colored specimens have varying degrees of transparency. The mineral occurs as equant to short prismatic crystals up to , in sheaf-like or saddle-shaped aggregates, or as crusts. Individual crystals are commonly rounded and striated. Structure Zinc ions are surrounded by oxygen in a nearly perfect trigonal bipyramid and phosphate groups are tetrahedral. The crystal structure consists of zig-zag chains of Zn1 polyhedra linked by phosphate groups and pairs of Zn2 polyhedra. In each unit cell are two formula units of Zn2(PO4)(OH).Cocco, p. 321.

Parahopeite
Zinc phosphate is an inorganic compound with the formula Zn3( PO4)2. This white powder is widely used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead). It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become the most commonly used corrosion inhibitor. Zinc phosphate coats better on a crystalline structure than bare metal, so a seeding agent is often used as a pre-treatment. One common agent is sodium pyrophosphate. Minerals Natural forms of zinc phosphate include minerals hopeite and parahopeite. A somewhat similar mineral is natural hydrous zinc phosphate called tarbuttite, Zn2(PO4)(OH). Both are known from oxidation zones of Zn ore beds and were formed through oxidation of sphalerite by the presence of phosphate-rich solutions. The anhydrous form has not yet been found naturally. Dentistry Zinc phosphate dental cement is one of the oldest a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Encyclopædia Britannica Eleventh Edition
The ''Encyclopædia Britannica'' Eleventh Edition (1910–1911) is a 29-volume reference work, an edition of the ''Encyclopædia Britannica''. It was developed during the encyclopaedia's transition from a British to an American publication. Some of its articles were written by the best-known scholars of the time. This edition of the encyclopaedia, containing 40,000 entries, has entered the public domain and is easily available on the Internet. Its use in modern scholarship and as a reliable source has been deemed problematic due to the outdated nature of some of its content. Modern scholars have deemed some articles as cultural artifacts of the 19th and early 20th centuries. Background The 1911 eleventh edition was assembled with the management of American publisher Horace Everett Hooper. Hugh Chisholm, who had edited the previous edition, was appointed editor in chief, with Walter Alison Phillips as his principal assistant editor. Originally, Hooper bought the rights to th ...

Penelope Spencer
Penelope Spencer (30 December 1901–3 October 1993) was an English dancer who is remembered for her modern approach to free-style dancing and choreography. Early life Born in the London district of Battersea, she was the daughter of geologist Leonard James Spencer and of Edith Mary Close, a schoolteacher. From the age of 11, she was trained in theatre and ballet at the Italia Conti Academy where she studied under the pioneering modern dancer Margaret Morris. Career In 1921, on Morris's recommendation, she was engaged by Rutland Boughton to stage dances and choruses for the Glastonbury Festival, some of which he incorporated in his opera ''The Immortal Hour''. She then spent a brief period as principal dancer at the British National Opera Company performing in '' The Jewels of the Madonna''. From 1924, she arranged dances for the productions of Sybil Thorndike and Lewis Casson, including ''The Cenci'' and ''Henry VIII'', and also associated with Nigel Playfair, the manager of t ...
