Aula Magna (Central University Of Venezuela)
The Aula Magna is an auditorium at the Central University of Venezuela. It is located within the University City of Caracas, next to the University's main library building. The hall was designed by the Venezuelan architect Carlos Raúl Villanueva in the 1940s and built by the Danish company Christiani & Nielsen from 1952–53. It was declared a UNESCO World Heritage Site in November 2000 for being artistically and architecturally significant. The most notable feature of the hall is its acoustic 'clouds', which serve both aesthetic and practical functions. They are an element of the hall's design which contributed to the science of interior space acoustics, though the building exterior is also architecturally significant. The Aula Magna has been named the "most important auditorium" at the university. This is in part because of practicality: it is the largest capacity auditorium, being able to hold approximately 2,700 people with removable seats. However, it is also significant ...

University City Of Caracas
The University City of Caracas (Spanish: ''Ciudad Universitaria de Caracas''), also known by the acronym CUC, is the main campus of the Central University of Venezuela (UCV), located in central Caracas, the capital of Venezuela. It was designed by the Venezuelan architect Carlos Raúl Villanueva and was declared a World Heritage Site by UNESCO in 2000. The Ciudad Universitaria de Caracas is considered a "masterpiece" of architecture and urban planning, and greatly influenced Venezuelan architecture. Villanueva oversaw design from the end of the Second World War, and oversaw the campus construction for 20 years. He gave his skills and also vision of design principles to it, and it remains the only university campus designed by a single architect in the 20th century that has received cultural heritage recognition by UNESCO. The campus comprises a variety of different environments; its northern half is a Botanical Garden, with extensive sports facilities at its east, west and south. T ...

Pan-American Conference
The Conferences of American States, commonly referred to as the Pan-American Conferences, were meetings of the Pan-American Union, an international organization for cooperation on trade. James G. Blaine, a United States politician, Secretary of State and presidential contender, first proposed establishment of closer ties between the United States and its southern neighbors and proposed international conference. Blaine hoped that ties between the United States and its southern counterparts would open Latin American markets to US trade. History On 2 December 1823, President James Monroe delivered the 'Monroe Doctrine' which would eventually influence Secretary of State James G. Blaine to push for the creation of the Pan-American Conferences. In this speech, President Monroe stated that any further attempts by the Europeans to colonize the Americas (North, Central and South) would be seen as an act of aggression and would risk intervention by the United States. This doctrine wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incandescent
Incandescence is the emission of electromagnetic radiation (including visible light) from a hot body as a result of its high temperature. The term derives from the Latin verb ''incandescere,'' to glow white. A common use of incandescence is the incandescent light bulb, now being phased out. Incandescence is due to thermal radiation. It usually refers specifically to visible light, while thermal radiation refers also to infrared or any other electromagnetic radiation. Observation and use In practice, virtually all solid or liquid substances start to glow around , with a mildly dull red color, whether or not a chemical reaction takes place that produces light as a result of an exothermic process. This limit is called the Draper point. The incandescence does not vanish below that temperature, but it is too weak in the visible spectrum to be perceptible. At higher temperatures, the substance becomes brighter and its color changes from red towards white and finally blue. Inca ...

Cashmere Wool
Cashmere wool, usually simply known as cashmere, is a fiber obtained from cashmere goats, pashmina goats, and some other breeds of goat. It has been used to make yarn, textiles and clothing for hundreds of years. Cashmere is closely associated with the Kashmir shawl, the word "cashmere" deriving from an anglicisation of ''Kashmir'', when the Kashmir shawl reached Europe in the 19th century. Both the soft undercoat and the guard hairs may be used; the softer hair is reserved for textiles, while the coarse guard hair is used for brushes and other non-apparel purposes. A number of countries produce cashmere and have improved processing techniques over the years but China and Mongolia are two of the leading producers as of 2019. Afghanistan is ranked third. Some yarns and clothing marketed as containing cashmere have been found to contain little to no cashmere fiber, so more stringent testing has been requested to make sure items are fairly represented.

Theater (structure)
A theater, theatre or playhouse, is a structure where theatre, theatrical works, performing arts and musical Concert, concerts are presented. The theater building serves to define the performance and audience spaces. The facility usually is organized to provide support areas for performers, the technical crew and the audience members, as well as the stage where the performance takes place. There are as many types of theaters as there are types of performance. Theaters may be built specifically for a certain types of productions, they may serve for more general performance needs or they may be adapted or converted for use as a theater. They may range from open-air amphitheaters to ornate, cathedral-like structures to simple, undecorated rooms or black box theaters. A theatre used for opera performances is called an opera house. A theater is not required for performance (as in site-specific theatre, environmental theater or street theatre, street theater), this article is about s ...

Fiberglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non- magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Architectural Acoustics
Architectural acoustics (also known as building acoustics) is the science and engineering of achieving a good sound within a building and is a branch of acoustical engineering. The first application of modern scientific methods to architectural acoustics was carried out by the American physicist Wallace Sabine in the Fogg Museum lecture room. He applied his newfound knowledge to the design of Symphony Hall, Boston. Architectural acoustics can be about achieving good speech intelligibility in a theatre, restaurant or railway station, enhancing the quality of music in a concert hall or recording studio, or suppressing noise to make offices and homes more productive and pleasant places to work and live in. Architectural acoustic design is usually done by acoustic consultants. Building skin envelope This science analyzes noise transmission from building exterior envelope to interior and vice versa. The main noise paths are roofs, eaves, walls, windows, door and penetrations. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchestra
An orchestra (; ) is a large instrumental ensemble typical of classical music, which combines instruments from different families. There are typically four main sections of instruments: * bowed string instruments, such as the violin, viola, cello, and double bass * woodwinds, such as the flute, oboe, clarinet, saxophone, and bassoon * Brass instruments, such as the horn, trumpet, trombone, cornet, and tuba * percussion instruments, such as the timpani, snare drum, bass drum, cymbals, triangle, tambourine, and mallet percussion instruments Other instruments such as the piano, harpsichord, and celesta may sometimes appear in a fifth keyboard section or may stand alone as soloist instruments, as may the concert harp and, for performances of some modern compositions, electronic instruments and guitars. A full-size Western orchestra may sometimes be called a or philharmonic orchestra (from Greek ''phil-'', "loving", and "harmony"). The actual number of musicians employ ...
