Packard Campus For Audio-Visual Conservation
The National Audiovisual Conservation Center, also known as the Packard Campus for Audio-Visual Conservation, is the Library of Congress's audiovisual archive located inside Mount Pony in Culpeper, Virginia. Establishment From 1969 to 1988, the campus was a high-security storage facility operated by the Federal Reserve Board. With the approval of the United States Congress in 1997, it was purchased by the David and Lucile Packard Foundation from the Federal Reserve Bank of Richmond via a $5.5 million grant, done on behalf of the Library of Congress. With a further $150 million from the Packard Humanities Institute and $82.1 million from Congress, the facility was transformed into the National Audio-Visual Conservation Center, which completed construction in mid-2007, and after transfer of the bulk of archives, opened for free public movie screenings on most weekends in the fall 2008. The campus offered, for the first time, a single site to store all 6.3 million pieces of the li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freeze-drying
Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process that involves freezing the product and lowering pressure, removing the ice by sublimation. This is in contrast to dehydration by most conventional methods that evaporate water using heat. Because of the low temperature used in processing, the rehydrated product retains much of its original qualities. When solid objects like strawberries are freeze dried the original shape of the product is maintained. If the product to be dried is a liquid, as often seen in pharmaceutical applications, the properties of the final product are optimized by the combination of excipients (i.e., inactive ingredients). Primary applications of freeze drying include biological (e.g., bacteria and yeasts), biomedical (e.g., surgical transplants), food processing (e.g., coffee) and preservation. History The Inca were freeze drying potatoes into chuño from the 13th century. The process involved mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Eastman House
The George Eastman Museum, also referred to as ''George Eastman House, International Museum of Photography and Film'', the world's oldest museum dedicated to photography and one of the world's oldest film archives, opened to the public in 1949 in Rochester, New York. World-renowned for its collections in the fields of photography and cinema, the museum is also a leader in film preservation and photograph conservation, educating archivists and conservators from around the world. Home to the 500-seat Dryden Theatre, the museum is located on the estate of entrepreneur and philanthropist George Eastman, the founder of Eastman Kodak Company. The estate was designated a National Historic Landmark in 1966. History The Rochester estate of George Eastman (1854–1932) was bequeathed upon his death to the University of Rochester. University presidents (first Benjamin Rush Rhees, then Alan Valentine) occupied Eastman's mansion as a residence for ten years. In 1948, the university ...

Art Deco
Art Deco, short for the French ''Arts Décoratifs'', and sometimes just called Deco, is a style of visual arts, architecture, and product design, that first appeared in France in the 1910s (just before World War I), and flourished in the United States and Europe during the 1920s and 1930s. Through styling and design of the exterior and interior of anything from large structures to small objects, including how people look (clothing, fashion and jewelry), Art Deco has influenced bridges, buildings (from skyscrapers to cinemas), ships, ocean liners, trains, cars, trucks, buses, furniture, and everyday objects like radios and vacuum cleaners. It got its name after the 1925 Exposition internationale des arts décoratifs et industriels modernes (International Exhibition of Modern Decorative and Industrial Arts) held in Paris. Art Deco combined modern styles with fine craftsmanship and rich materials. During its heyday, it represented luxury, glamour, exuberance, and faith in socia ...

Silent Film
A silent film is a film with no synchronized Sound recording and reproduction, recorded sound (or more generally, no audible dialogue). Though silent films convey narrative and emotion visually, various plot elements (such as a setting or era) or key lines of dialogue may, when necessary, be conveyed by the use of intertitle, title cards. The term "silent film" is something of a misnomer, as these films were almost always accompanied by live sounds. During the silent era that existed from the mid-1890s to the late 1920s, a piano, pianist, theatre organ, theater organist—or even, in large cities, a small orchestra—would often play music to accompany the films. Pianists and organists would play either from sheet music, or musical improvisation, improvisation. Sometimes a person would even narrate the inter-title cards for the audience. Though at the time the technology to synchronize sound with the film did not exist, music was seen as an essential part of the viewing experie ...

Overview Overview includes: * Pipe organs, which use air moving through pipes to produce sounds. Since the 16th century, pipe organs have used various materials for pipes, which can vary widely in timbre and volume. Increasingly hybrid organs are appearing in which pipes are augmented with electric additions. Great economies of space and cost are possible especially when the lowest (and largest) of the pipes can be replaced; * Non-piped organs, which include: ** pump organs, also known as reed organs or harmoniums, which ...

Gigabyte
The gigabyte () is a multiple of the unit byte for digital information. The prefix '' giga'' means 109 in the International System of Units (SI). Therefore, one gigabyte is one billion bytes. The unit symbol for the gigabyte is GB. This definition is used in all contexts of science (especially data science), engineering, business, and many areas of computing, including storage capacities of hard drives, solid state drives, and tapes, as well as data transmission speeds. However, the term is also used in some fields of computer science and information technology to denote (10243 or 230) bytes, particularly for sizes of RAM. Thus, prior to 1998, some usage of ''gigabyte'' has been ambiguous. To resolve this difficulty, IEC 80000-13 clarifies that a ''gigabyte'' (GB) is 109 bytes and specifies the term ''gibibyte'' (GiB) to denote 230 bytes. These differences are still readily seen for example, when a 400 GB drive's capacity is displayed by Microsoft Windows as 372 ...

Petabyte
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as The Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nitrate Film
Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms. It was also used to replace gunpowder as a low-order explosive in mining and other applications. In the form of collodion it was also a critical component in an early photographic emulsion, the use of which revolutionized photography in the 1860s. Production The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose. The quality of the cellulose is important. Hemicellulose, lignin, pentosans, and mineral salts give inferior nitrocelluloses. In precise chemical terms, nitrocellulose is not a nitro compound, but a nitrate ester. The glucose repeat unit (anhydroglucose) within the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
