Conservation-restoration Of Leonardo Da Vinci's The Last Supper
The conservation-restoration of Leonardo da Vinci's ''The Last Supper'' is an ongoing project that has spanned many centuries. Completed in the late 15th century by the Renaissance artist Leonardo da Vinci, the mural is located in the refectory of the Convent of Santa Maria delle Grazie, Milan, Italy. ''The Last Supper'' was commissioned by Ludovico Sforza, Duke of Milan in 1495, as part of a series of renovations to the convent with the intention that the location would become the Sforza family mausoleum. Work began on ''The Last Supper'' in 1495 and lasted until 1498. The scene is understood to depict the Bible verse John 13:22, showing the reactions of the Twelve Disciples, at the Last Supper, in the moments following Jesus’s announcement that one among them will betray him. Techniques and Materials Used When he received the commission for ''The Last Supper'', Leonardo da Vinci had never worked on a piece of this great a size, fifteen feet high by almost twenty-nine fe ...

Magnesium
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. In the cosmos, magnesium is produced in large, aging stars by the sequential addition of three helium nuclei to a carbon nucleus. When such stars explode as supernovas, much of the magnesium is expelled into the interstellar medium where it ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Casein
Casein ( , from Latin ''caseus'' "cheese") is a family of related phosphoproteins (CSN1S1, αS1, aS2, CSN2, β, K-casein, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in breast milk, human milk. Sheep's milk, Sheep and buffalo milk have a higher casein content than other types of milk with human milk having a particularly low casein content. Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive. The most common form of casein is sodium caseinate. In milk, casein undergoes phase separation to form colloidal casein micelles, a type of secreted biomolecular condensate. As a food source, casein supplies amino acids, carbohydrates, and two essential elements, calcium and phosphorus. Composition Casein contains a high number of proline amino acids which hinder the formation of common secondary structural motifs of proteins. There are also no di ...

Shellac
Shellac () is a resin secreted by the female lac bug on trees in the forests of India and Thailand. It is processed and sold as dry flakes and dissolved in alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish. Shellac functions as a tough natural primer, sanding sealant, tannin-blocker, odour-blocker, stain, and high-gloss varnish. Shellac was once used in electrical applications as it possesses good insulation qualities and it seals out moisture. Phonograph and 78 rpm gramophone records were made of it until they were replaced by vinyl long-playing records from 1948 onwards. From the time it replaced oil and wax finishes in the 19th century, shellac was one of the dominant wood finishes in the western world until it was largely replaced by nitrocellulose lacquer in the 1920s and 1930s. Etymology ''Shellac'' comes from ''shell'' and ''lac'', a calque of French , 'lac in thin pieces', later , 'gum lac'. Most European langua ...

Lunette
A lunette (French ''lunette'', "little moon") is a half-moon shaped architectural space, variously filled with sculpture, painted, glazed, filled with recessed masonry, or void. A lunette may also be segmental, and the arch may be an arc taken from an oval. A lunette window is commonly called a ''half-moon window'', or fanlight when bars separating its panes fan out radially. If a door is set within a round-headed arch, the space within the arch above the door, masonry or glass, is a lunette. If the door is a major access, and the lunette above is massive and deeply set, it may be called a tympanum. A lunette is also formed when a horizontal cornice transects a round-headed arch at the level of the imposts, where the arch springs. If the top of the lunette itself is bordered by a hood mould it can also be considered a pediment. The term is also employed to describe the section of interior wall between the curves of a vault and its springing line. A system of intersectin ...

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry James

He is regarded as a key transitional figure between literary realism and literary modernism, and is considered by many to be among the greatest novelists in the English language. He was the son of Henry James Sr. and the brother of philosopher and psychologist William James and diarist Alice James. He is best known for his novels dealing with the social and marital interplay between ''émigré ''Americans, English people, and continental Europeans. Examples of such novels include '' The Portrait of a Lady'', ''The Ambassadors'', and ''The Wings of the Dove''. His later works were increasingly experimental. In describing the internal states of mind and social dynamics of his characters, James often wrote in a style in which ambiguous or contradictory motives and impressions were overlaid or juxtaposed in the discussion of a character's psyche. For their unique ambiguity, as well as for other aspects of their composition, his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
