Conservation-restoration Of The Statue Of Liberty
A centennial conservation-restoration of the Statue of Liberty (''Liberty Enlightening the World'') occurred between 1984 and 1986. The Statue of Liberty, by French sculptor Frédéric Auguste Bartholdi, is a colossal sculpture on Liberty Island in New York Harbor and is a part of the Statue of Liberty National Monument. Much of the restoration effort was based on unprecedented restorative methods, as metallurgical repair work on such a large scale had never been attempted. Many scientists, engineers, government organizations, and professional consultants evaluated and dealt with the various problems and tasks facing the restoration effort. The restored statue was reopened during Liberty Weekend, its 100-year anniversary celebration held July 3–6, 1986. Pre-restoration documentation efforts The preparations for the centennial celebration of the Statue of Liberty began in 1979. The centennial conservation-restoration project was formed by the National Park Service (NPS), the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statue Of Liberty Restoration Project
A statue is a free-standing sculpture in which the realistic, full-length figures of persons or animals are carved or cast in a durable material such as wood, metal or stone. Typical statues are life-sized or close to life-size; a sculpture that represents persons or animals in full figure but that is small enough to lift and carry is a statuette or figurine, whilst one more than twice life-size is a colossal statue. Statues have been produced in many cultures from prehistory to the present; the oldest-known statue dating to about 30,000 years ago. Statues represent many different people and animals, real and mythical. Many statues are placed in public places as public art. The world's tallest statue, '' Statue of Unity'', is tall and is located near the Narmada dam in Gujarat, India. Color Ancient statues often show the bare surface of the material of which they are made. For example, many people associate Greek classical art with white marble sculpture, but there is evide ...

Lead(II,IV) Oxide
Lead(II,IV) oxide, also called red lead or minium, is the inorganic compound with the formula Pb3O4. A bright red or orange solid, it is used as pigment, in the manufacture of batteries, and rustproof primer paints. It is an example of a mixed valence compound, being composed of both Pb(II) and Pb(IV) in the ratio of two to one. Structure Lead(II,IV) oxide has a tetragonal crystal structure at room temperature, which then transforms to an orthorhombic (Pearson symbol ''oP''28, Space group Pbam, No. 55) form at temperature . This phase transition only changes the symmetry of the crystal and slightly modifies the interatomic distances and angles.

Penny (United States Coin)
The cent, the United States one-cent coin (symbol: ¢), often called the "penny", is a unit of currency equaling one one-hundredth of a United States dollar. It has been the lowest face-value physical unit of U.S. currency since the abolition of the half-cent in 1857 (the abstract mill, which has never been minted, equal to a tenth of a cent, continues to see limited use in the fields of taxation and finance). The first U.S. cent was produced in 1787, and the cent has been issued primarily as a copper or copper-plated coin throughout its history. The penny is issued in its current form as the Lincoln cent, with its obverse featuring the profile of President Abraham Lincoln since 1909, the centennial of his birth. From 1959 (the sesquicentennial of Lincoln's birth) to 2008, the reverse featured the Lincoln Memorial. Four different reverse designs in 2009 honored Lincoln's 200th birthday and a new, "permanent" reverse – the Union Shield – was introduced in 2010. The coin is ...

Salmon (color)
Salmon is a range of pinkish- orange to light pink colors, named after the color of salmon flesh. The first recorded use of ''salmon'' as a color name in English was in 1776.Maerz and Paul ''A Dictionary of Color'' New York:1930 McGraw-Hill Page 203; Color Sample of Salmon: Page 43 Plate 10 Color Sample A7 The actual color of salmon flesh varies from almost white to light orange, depending on their levels of the carotenoid astaxanthin due to how rich a diet of krill and shrimp the fish feeds on; salmon raised on fish farms are given non-synthetic or artificial coloring in their food. __TOC__ Variations of salmon Light salmon resembles the color salmon, but is lighter, not to be confused with dark salmon, which resembles salmon pink but is darker. Salmon pink (or ''salmon'' in Crayola crayons) was introduced by Crayola in 1949. See the List of Crayola crayon colors. Dark salmon resembles the color salmon, but is darker.

Patina
Patina ( or ) is a thin layer that variously forms on the surface of copper, brass, bronze and similar metals and metal alloys ( tarnish produced by oxidation or other chemical processes) or certain stones and wooden furniture (sheen produced by age, wear, and polishing), or any similar acquired change of a surface through age and exposure. Additionally, the term is used to describe the aging of high-quality leather. The patinas on leather goods are unique to the type of leather, frequency of use, and exposure. Patinas can provide a protective covering to materials that would otherwise be damaged by corrosion or weathering. They may also be aesthetically appealing. Usage On metal, patina is a coating of various chemical compounds such as oxides, carbonates, sulfides, or sulfates formed on the surface during exposure to atmospheric elements (oxygen, rain, acid rain, carbon dioxide, sulfur-bearing compounds). In common parlance, weathering rust on steel is often mistakenly r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Sheathing
Copper sheathing is the practice of protecting the under-water hull of a ship or boat from the corrosive effects of salt water and biofouling through the use of copper plates affixed to the outside of the hull. It was pioneered and developed by the Royal Navy during the 18th century. In antiquity, ancient Greeks used lead plates to protect the underwater hull. Development Deterioration of the hull of a wooden ship was a significant problem during the Age of Sail. Ships' hulls were under continuous attack by shipworm, barnacles and various marine weeds, all of which had some adverse effect on the ship, be it structurally, in the case of the worm, or affecting speed and handling in the case of the weeds. The most common methods of dealing with these problems were through the use of wood, and sometimes lead, sheathing. Expendable wood sheathing effectively provided a non-structural skin to the hull for the worm to attack, and could be easily replaced in dry dock at regular inter ...

Scaffolding
Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man-made structures. Scaffolds are widely used on site to get access to heights and areas that would be otherwise hard to get to. Unsafe scaffolding has the potential to result in death or serious injury. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half pipes and art projects. There are five main types of scaffolding used worldwide today. These are tube and coupler (fitting) components, prefabricated modular system scaffold components, H-frame / façade modular system scaffolds, timber scaffolds and bamboo scaffolds (particularly in China and India). Each type is made from several components which often include: * A base jack or plate which is a load-bearing base for the ...

Computer-aided Design
Computer-aided design (CAD) is the use of computers (or ) to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software are helpful in protecting products and inventions when used in patent applications. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The terms computer-aided drafting (CAD) and computer aided design and drafting (CADD) are also used. Its use in designing electronic systems is known as '' electronic design automation'' (''EDA''). In mechanical design it is known as ''mechanical design automation'' (''MDA''), which includes the process of creating a technical drawing with the use of computer software. CAD software for mechanical design uses either vector-based graphic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
