Josiah Marshall Heath
Josiah Marshall Heath (8 November 1790 – 28 January 1851) was an English metallurgist, businessman and naturalist, who invented the use of manganese to deoxidise steel. In India he learned the local steel-making processes, including wootz, but having failed to found a profitable steel mill there he returned to England and settled in Sheffield. His patent kick-started Sheffield's steel industry, but the poor wording of his patent caused competitors not to pay him royalties, and he died in poverty. Career in India Heath was the son of Rear-Admiral William Heath (1749-1815) and his first wife Rebecca (1765-1795) who was the daughter of Rev. Josiah Marshall, rector of Fahan. He joined the East India Company in 1806 as a Writer in the Madras Presidency. In 1808 he became an assistant to the secretary of the Board of Revenue and in 1809 an examiner under the Secretary to the Board of Trade. In 1811 he became a registrar of Chingleput Zilla. In 1812 he was deputy commercial resid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals, including the production of metals and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mineral processing, the extraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menai Suspension Bridge
The Menai Suspension Bridge ( or ) is a suspension bridge spanning the Menai Strait between the island of Anglesey and the mainland of Wales. Designed by Thomas Telford and completed in 1826, it was the world's first major suspension bridge. The bridge still carries road traffic and is a Grade I listed structure. Background The Menai Strait was created by glacial erosion along a line of weakness associated with the Menai Strait fault system. During a series of Pleistocene glaciations (that lasted from about 2,580,000 to 11,700 years ago), a succession of ice-sheets moved from northeast to southwest across Anglesey and neighbouring Gwynedd, scouring the underlying rock and creating a series of linear bedrock hollows. The deepest of these channels eventually became flooded by the sea as the ice sheets receded, forming the Menai Strait. As Anglesey has been an island throughout recorded human history, the only way to reach it was by crossing the strait. However, this has always b ...

Greater Asiatic Yellow Bat
The greater Asiatic yellow bat (''Scotophilus heathii'') is a species of vesper bat. It is found in Afghanistan, Bangladesh, Cambodia, China, India, Indonesia, Laos, Myanmar, Nepal, Pakistan, Philippines, Sri Lanka, Thailand and Vietnam. Like many bats, females have delayed ovulation, with the ability to store sperm. This makes them particularly of interest to biologists. Studies have shown that seasonal changes in hormones allow them to deposit fat before the onset of winter. It is named after Josiah Marshall Heath, who presented the type specimen to the Zoological Society of London The Zoological Society of London (ZSL) is a charity and organization devoted to the worldwide animal conservation, conservation of animals and their habitat conservation, habitats. It was founded in 1826. Since 1828, it has maintained London Zo .... Description The head and body length of the greater Asiatic yellow bat is , the forearms measure , and the wingspan is.

Chapman & Hall
Chapman & Hall is an imprint owned by CRC Press, originally founded as a British publishing house in London in the first half of the 19th century by Edward Chapman and William Hall. Chapman & Hall were publishers for Charles Dickens (from 1840 until 1844 and again from 1858 until 1870), Thomas Carlyle, William Thackeray, Elizabeth Barrett Browning, Anthony Trollope, Eadweard Muybridge and Evelyn Waugh. History Upon Hall's death in 1847, Chapman's cousin Frederic Chapman began his progress through the ranks of the company and eventually becoming a partner in 1858 and sole proprietor on Edward Chapman's retirement from Chapman & Hall in 1866. In 1868 author Anthony Trollope bought a third of the company for his son, Henry Merivale Trollope. From 1902 to 1930 the company's managing director was Arthur Waugh. In the 1930s the company merged with Methuen & Co. Ltd., Methuen, a merger which, in 1955, participated in forming the Associated Book Publishers. The latter was acquire ...

Redox
Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. The oxidation and reduction processes occur simultaneously in the chemical reaction. There are two classes of redox reactions: * Electron transfer, Electron-transfer – Only one (usually) electron flows from the atom, ion, or molecule being oxidized to the atom, ion, or molecule that is reduced. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * Atom transfer – An atom transfers from one Substrate (chemistry), substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously, the oxidation state of oxygen decreases as it accepts electrons r ...

Josiah Marshall Heath Grave Kensal Green Cemetery
Josiah () or Yoshiyahu was the 16th king of Judah (–609 BCE). According to the Hebrew Bible, he instituted major religious reforms by removing official worship of gods other than Yahweh. Until the 1990s, the biblical description of Josiah’s reforms were usually considered to be more or less accurate, but that is now heavily debated. According to the Bible, Josiah became king of the Kingdom of Judah at the age of eight, after the assassination of his father, King Amon, and reigned for 31 years, from 641/640 to 610/609 BCE. Josiah is known only from biblical texts; no reference to him exists in other surviving texts of the period from ancient Egypt or Babylon, and no clear archaeological evidence, such as inscriptions bearing his name, has ever been found. However, a seal bearing the name " Nathan-melech," the name of an administrative official under King Josiah according to , dating to the 7th century BCE, was found in situ in an archeological site in Jerusalem.

Carbide
In chemistry, a carbide usually describes a compound composed of carbon and a metal. In metallurgy, carbiding or carburizing is the process for producing carbide coatings on a metal piece. Interstitial / Metallic carbides The carbides of the group 4, 5 and 6 transition metals (with the exception of chromium) are often described as interstitial compounds. These carbides have metallic properties and are refractory. Some exhibit a range of stoichiometries, being a non-stoichiometric mixture of various carbides arising due to crystal defects. Some of them, including titanium carbide and tungsten carbide, are important industrially and are used to coat metals in cutting tools. The long-held view is that the carbon atoms fit into octahedral interstices in a close-packed metal lattice when the metal atom radius is greater than approximately 135 pm: *When the metal atoms are cubic close-packed, (ccp), then filling all of the octahedral interstices with carbon achieves 1:1 ...

Carbon
Carbon () is a chemical element; it has chemical symbol, symbol C and atomic number 6. It is nonmetallic and tetravalence, tetravalent—meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. Carbon makes up about 0.025 percent of Earth's crust. Three Isotopes of carbon, isotopes occur naturally, carbon-12, C and carbon-13, C being stable, while carbon-14, C is a radionuclide, decaying with a half-life of 5,700 years. Carbon is one of the timeline of chemical element discoveries#Pre-modern and early modern discoveries, few elements known since antiquity. Carbon is the 15th abundance of elements in Earth's crust, most abundant element in the Earth's crust, and the abundance of the chemical elements, fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. Carbon's abundance, its unique diversity of organic compounds, and its unusual abi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
