Ardmore, Pennsylvania
Ardmore is an unincorporated community and census-designated place (CDP) spanning the border between Delaware and Montgomery counties in the U.S. state of Pennsylvania. The population was 12,455 at the 2010 census and had risen to 13,566 in the 2020 census. Ardmore is a suburb on the west side of Philadelphia within Lower Merion Township in Montgomery County and Haverford Township in Delaware County. Originally named "Athensville" in 1853, the community and its railroad station were renamed Ardmore in 1873 by the Pennsylvania Railroad, on whose Main Line, west out of Philadelphia, Ardmore sits at Milepost 8.5. The Autocar Company moved its headquarters to Ardmore in 1899 and constructed a factory on the edge of the downtown area. The factory closed in 1954; during demolition in 1956, a major fire broke out that threatened the downtown area before it was extinguished. Today, Ardmore consistently ranks among the most desirable suburbs of Philadelphia. Geography According t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White House
The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue Northwest, Washington, D.C., NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800. The term "White House" is often used as a metonym for the Executive Office of the President of the United States, president and his advisers. The residence was designed by Irish-born architect James Hoban in the Neoclassical architecture, neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800, using Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) added low colonnades on each wing that concealed stables and storage. In 1814, during the War of 1812, the mansion was set ablaze by British forces in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1950 Births
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 '' Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Zincite
Zincite is the mineral form of zinc oxide ( Zn O). Its crystal form is rare in nature; a notable exception to this is at the Franklin and Sterling Hill Mines in New Jersey, an area also famed for its many fluorescent minerals. It has a hexagonal crystal structure and a color that depends on the presence of impurities. The zincite found at the Franklin Furnace is red-colored, mostly due to iron and manganese dopants, and associated with willemite and franklinite. Zincite crystals can be grown artificially, and synthetic zincite crystals are available as a by-product of zinc smelting. Synthetic crystals can be colorless or can range in color from dark red, orange, or yellow to light green. Both natural and synthetic zincite crystals are significant for their early use as semiconductor crystal detectors in the early development of crystal radios before the advent of vacuum tubes. As an early radio detector it was used in conjunction with another mineral, galena, and this de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franklinite
Franklinite is an oxide mineral belonging to the normal spinel subgroup's iron (Fe) series, with the formula ZnFe3+2O4. As with another spinel member magnetite, both ferrous (2+) and ferric (3+) iron may be present in Franklinite samples. Divalent iron and/or manganese (Mn) may commonly accompany zinc (Zn) and trivalent manganese may substitute for some ferric iron. At its type locality, Franklinite can be found with a wide array of minerals, many of which are fluorescent. More commonly, it occurs with willemite, calcite, and red zincite. In these rocks, it forms as disseminated small black crystals with their octahedral faces visible at times. It may rarely be found as a single large euhedral crystal. Franklinite was a minor ore of uranium, sulfuric acid, and mercury. It is named after its local discovery at the Franklin Furnace, Franklin Mine and Sterling Hill Mining Museum, Sterling Hill Mines in New Jersey.

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Public Library
A public library is a library that is accessible by the general public and is usually funded from public sources, such as taxes. It is operated by librarians and library paraprofessionals, who are also Civil service, civil servants. There are five fundamental characteristics shared by public libraries: they are generally supported by taxes (usually local, though any level of government can and may contribute); they are governed by a board to serve the public interest; they are open to all, and every community member can access the collection; they are entirely voluntary, no one is ever forced to use the services provided and they provide library and information services services without charge. Public libraries exist in many countries across the world and are often considered an essential part of having an educated and literate population. Public libraries are distinct from research library, research libraries, school library, school libraries, academic library, academic librar ...

Mobile, Alabama
Mobile ( , ) is a city and the county seat of Mobile County, Alabama, United States. The population within the city limits was 187,041 at the 2020 census, down from 195,111 at the 2010 census. It is the fourth-most-populous city in Alabama, after Huntsville, Birmingham, and Montgomery. Alabama's only saltwater port, Mobile is located on the Mobile River at the head of Mobile Bay on the north-central Gulf Coast. The Port of Mobile has always played a key role in the economic health of the city, beginning with the settlement as an important trading center between the French colonists and Native Americans, down to its current role as the 12th-largest port in the United States.Drechsel, Emanuel.

Plinth
A pedestal (from French ''piédestal'', Italian ''piedistallo'' 'foot of a stall') or plinth is a support at the bottom of a statue, vase, column, or certain altars. Smaller pedestals, especially if round in shape, may be called socles. In civil engineering, it is also called ''basement''. The minimum height of the plinth is usually kept as 45 cm (for buildings). It transmits loads from superstructure to the substructure and acts as the retaining wall for the filling inside the plinth or raised floor. In sculpting, the terms base, plinth, and pedestal are defined according to their subtle differences. A base is defined as a large mass that supports the sculpture from below. A plinth is defined as a flat and planar support which separates the sculpture from the environment. A pedestal, on the other hand, is defined as a shaft-like form that raises the sculpture and separates it from the base. An elevated pedestal or plinth that bears a statue, and which is raised from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fallingwater
Fallingwater is a house designed by the architect Frank Lloyd Wright in 1935 in the Laurel Highlands of southwest Pennsylvania, about southeast of Pittsburgh in the United States. It is built partly over a waterfall on Bear Run in the Mill Run section of Stewart Township, Fayette County, Pennsylvania. The house was designed to serve as a weekend retreat for Liliane and Edgar J. Kaufmann, the owner of Pittsburgh's Kaufmann's Department Store. After its completion, ''Time'' called Fallingwater Wright's "most beautiful job" and it is listed among '' Smithsonian''s "Life List of 28 Places to See Before You Die". The house was designated a National Historic Landmark on May 11th, 1976. In 1991, members of the American Institute of Architects named Fallingwater the "best all-time work of American architecture" and in 2007, it was ranked 29th on the list of America's Favorite Architecture according to the AIA. The house and seven other Wright constructions were inscribed as a Worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historic Paint Analysis
Historic paint analysis, or architectural paint research, is the scientific analysis of a broad range of architectural finishes, and is primarily used to determine the color and behavior of surface finishes at any given point in time. This helps us to understand the building's structural history and how its appearance has changed over time. Historic paint analysis shares a common methodology with the conservation and restoration of paintings used to conserve and restore two- and three dimensional works of art. This involves the identification of components such as organic or inorganic pigments and dyes contained in the pigments. Historic paint analysis also identifies the pigments' media of suspension such as (water, oil, or latex and the paints' associated substrate. A variety of techniques are used to identify and analyze the pigment layers and finish exposure, including Finish Exposure, optical microscopy, fluorescent light microscopy, polarized light microscopy, and Fourier- ...
