J. A. Voelcker (chemist, Born 1854)
John Augustus Voelcker Order of the Indian Empire, CIE (24 June 1854 – 6 November 1937) was an English agricultural chemist and the second son of the German-born English chemist Augustus Voelcker (1822–1884). John Augustus (Jr.) succeeded his father as consulting chemist to the Royal Agricultural Society of England and continued research on soil fertility. He headed a committee that examined issues in Indian agriculture in 1891. Early life and career John was the second of five sons of Augustus Voelcker and born at Cirencester. After school he studied chemistry under Temple Orme before joining University College where his chemistry teacher was Professor Alexander William Williamson. He was also a long distance runner and a member of the London Athletic Club. He won two medals at the 1881 AAA Championships. Voelcker then, like his father, studied chemistry in Giessen and received a doctorate for work on the composition of apatite and natural forms of calcium phosphate. He then ...

J A Voelcker CIE
J, or j, is the tenth Letter (alphabet), letter in the Latin alphabet, used in the English alphabet, modern English alphabet, the alphabets of other western European languages and others worldwide. Its usual name in English is English alphabet#Letter names, ''jay'' (pronounced ), with a now-uncommon variant ''jy'' ."J", ''Oxford English Dictionary,'' 2nd edition (1989) When used in the International Phonetic Alphabet for the palatal approximant, ''y'' sound, it may be called ''yod'' or ''jod'' (pronounced or ). History The letter ''J'' used to be used as the swash (typography), swash letter ''I'', used for the letter I at the end of Roman numerals when following another I, as in XXIIJ or xxiij instead of XXIII or xxiii for the Roman numeral twenty-three. A distinctive usage emerged in Middle High German. Gian Giorgio Trissino (1478–1550) was the first to explicitly distinguish I and J as representing separate sounds, in his ''Ɛpistola del Trissino de le lettere nuω ...

Calcium Sulphate
Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO4 and related hydrates. In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum. It has many uses in industry. All forms are white solids that are poorly soluble in water.Franz Wirsching "Calcium Sulfate" in Ullmann's Encyclopedia of Industrial Chemistry, 2012 Wiley-VCH, Weinheim. Calcium sulfate causes permanent hardness in water. Hydration states and crystallographic structures The compound exists in three levels of hydration corresponding to different crystallographic structures and to minerals: * (anhydrite): anhydrous state. The structure is related to that of zirconium orthosilicate (zircon): is 8-coordinate, is tetrahedral, O is 3-coordinate. * (gypsum and selenite (mineral)): dihydrate. * (bassanite): hemihydrate, also known as plaster of Paris.

Fluorapatite
Fluorapatite, often with the alternate spelling of fluoroapatite, is a phosphate mineral with the formula Ca5(PO4)3F (calcium fluorophosphate). Fluorapatite is a hard crystalline solid. Although samples can have various color (green, brown, blue, yellow, violet, or colorless), the pure mineral is colorless, as expected for a material lacking transition metals. Along with hydroxylapatite, it can be a component of tooth enamel, but for industrial use both minerals are mined in the form of phosphate rock, whose usual mineral composition is primarily fluorapatite but often with significant amounts of the other. Fluorapatite crystallizes in a hexagonal crystal system. It is often combined as a solid solution with hydroxylapatite (Ca5(PO4)3OH or Ca10(PO4)6(OH)2) in biological matrices. Chlorapatite (Ca5(PO4)3Cl) is another related structure. Industrially, the mineral is an important source of both phosphoric and hydrofluoric acids. Fluorapatite as a mineral is the most common p ...

Companion Of The Order Of The Indian Empire
The Most Eminent Order of the Indian Empire is an order of chivalry founded by Queen Victoria on 1 January 1878. The Order includes members of three classes: #Knight Grand Commander (GCIE) #Knight Commander ( KCIE) #Companion ( CIE) No appointments have been made since 1947, the year that British India gained independence as the Union of India and Dominion of Pakistan. With the death of the last surviving knight, the Maharaja Meghrajji III of Dhrangadhra, the order became dormant in 2010. The motto of the Order is ''Imperatricis auspiciis'', (Latin for "Under the auspices of the Empress"), a reference to Queen Victoria, the first Empress of India. The Order is the junior British order of chivalry associated with the British Indian Empire; the senior one is The Most Exalted Order of the Star of India. History The British founded the Order in 1878 to reward British and native officials who served in British India. The Order originally had only one class (Companion), but exp ...

Fertiliser
A fertilizer (American English) or fertiliser (British English; see spelling differences) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment or hand-tool methods. Historically fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations and byproducts of human-nature industries (i.e. fish processing waste, or bloodmeal from a ...

Robert H
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto.

Allan Octavian Hume
Allan Octavian Hume, CB ICS (4 June 1829 – 31 July 1912) was a British civil servant, political reformer, ornithologist and botanist who worked in British India. He was the founder of the Indian National Congress. A notable ornithologist, Hume has been called "the Father of Indian Ornithology" and, by those who found him dogmatic, "the Pope of Indian Ornithology". As an administrator of Etawah, he saw the Indian Rebellion of 1857 as a result of misgovernance and made great efforts to improve the lives of the common people. The district of Etawah was among the first to be returned to normalcy and over the next few years Hume's reforms led to the district being considered a model of development. Hume rose in the ranks of the Indian Civil Service but like his father Joseph Hume, a radical member of parliament, he was bold and outspoken in questioning British policies in India. He rose in 1871 to the position of secretary to the Department of Revenue, Agriculture, and Commerce und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secretary Of State For India
His (or Her) Majesty's Principal Secretary of State for India, known for short as the India Secretary or the Indian Secretary, was the British Cabinet minister and the political head of the India Office responsible for the governance of the British Indian Empire (usually known simply as 'the Raj' or British India), Aden, and Burma. The post was created in 1858 when the East India Company's rule in Bengal ended and India, except for the Princely States, was brought under the direct administration of the government in Whitehall in London, beginning the official colonial period under the British Empire. In 1937, the India Office was reorganised which separated Burma and Aden under a new Burma Office, but the same Secretary of State headed both departments and a new title was established as His Majesty's Principal Secretary of State for India and Burma. The India Office and its Secretary of State were abolished in August 1947, when the United Kingdom granted independence in th ...
