1. There is some evidence of racetracks being developed in several ancient civilizations. The most impressive ancient racetracks were certainly the hippodromes of the Ancient Greeks and the circuses of the Roman Empire. Both of these structures were designed for horse and chariot racing. The stadium of the Circus Maximus in Ancient Rome, could hold 200, 000 spectators
2. This theory of social reproduction has been significantly theorised by Pierre Bourdieu. However Bourdieu as a social theorist has always been concerned with the dichotomy between the objective and subjective, or to put it another way, between structure and agency. Bourdieu has therefore built his theoretical framework around the important concepts of habitus, field and cultural capital. These concepts are based on the idea that objective structures determine individuals ' chances, through the mechanism of the habitus, where individuals internalise these structures. However, the habitus is also formed by, for example, an individual's position in various fields, their family and their everyday experiences. Therefore one's class position does not determine one's life chances, although it does play an important part, alongside other factors
3. An important field of current research concerns structures that were being restored at the time of the eruption. Some of the older, damaged, paintings could have been covered with newer ones, and modern instruments are being used to catch a glimpse of the long hidden frescoes. The probable reason why these structures were still being repaired around seventeen years after the earthquake was the increasing frequency of smaller quakes that led up to the eruption
4. However, these last levels of subdivisions of municipalities do not have their own local administration: they are mostly as the natural economical units for agricultural exploitation and are the reference space for families ( so they may be appended to the names of peoples and their land / housing properties ) and are still used in statistics. Historically, these structures have been used for defensive purpose as well, and were more tied to the local catholic church and parishes ( notably after the Reconquista )
5. Architects ' fee structures are typically based on a percentage of construction value, as a rate per unit area of the proposed construction, hourly rates or a fixed lump sum fee. Combinations of these structures are also common. Fixed fees are usually based on a project's allocated construction cost and can range between 4 and 12% of new construction cost, for commercial and institutional projects, depending on a project's size and complexity. Residential projects range from 12 to 20%. Renovation projects typically command higher percentages, as high as 15-20%
6. An optical system typically has many openings, or structures that limit the ray bundles. These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place, or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system. In general, these structures are called stops, and the aperture stop is the stop that determines the ray cone angle, or equivalently the brightness, at an image point
7. In 1868, Muybridge travelled to the newly acquired American territory of Alaska to photograph the Tlingit Native Americans, occasional Russian inhabitants, and dramatic landscapes for the US government. In 1871, the Lighthouse Board hired Muybridge to photograph lighthouses of the American west coast. From March to July, he travelled aboard the Lighthouse Tender Shubrick to document these structures. In 1873, Muybridge was commissioned by the US Army to photograph the Modoc War against the Native Americans in northern California and Oregon. Many of his stereoscopic photos were published widely, and can still be found today
8. The second debate has been over the ability to make universal claims about all cultures. Although Boas argued that anthropologists had yet to collect enough solid evidence from a diverse sample of societies to make any valid general or universal claims about culture, by the 1940s some felt ready. Whereas Kroeber and Benedict had argued that "culture"—which could refer to local, regional, or trans-regional scales—was in some way "patterned" or "configured, " some anthropologists now felt that enough data had been collected to demonstrate that it often took highly structured forms. The question these anthropologists debated was, were these structures statistical artifacts, or where they expressions of mental models? This debate emerged full-fledged in 1949, with the publication of George Murdock's Social Structure, and Claude Lévi-Strauss's Les Structures Élémentaires de la Parenté
9. In the US and Canada, many new houses are built in housing tracts, which provide homeowners a sense of "belonging" and the feeling they have "made the best use" of their money. However, these houses are sometimes built as cheaply and quickly as possible by large builders seeking to maximize profits. Many environmental health issues may be ignored or minimized in the construction of these structures. In one case in Benicia, California, a housing tract was built over an old landfill. Home buyers were never told, and only found out when some began having reactions to high levels of lead and chromium
10. In material sciences, many complicated inorganic and organometallic systems have been analyzed using single-crystal methods, such as fullerenes, metalloporphyrins, and other complicated compounds. Single-crystal diffraction is also used in the pharmaceutical industry, due to recent problems with polymorphs. The major factors affecting the quality of single-crystal structures are the crystal's size and regularity; recrystallization is a commonly used technique to improve these factors in small-molecule crystals. The Cambridge Structural Database contains over 500, 000 structures; over 99% of these structures were determined by X-ray diffraction
