Atrium

Atrium may refer to:

Atrium (architecture)

In architecture, an atrium (plural: atria or atriums) is a large open space located within a building. Atria were a common feature in Ancient Roman dwellings, providing light and ventilation to the interior. Modern atria, as developed in the late 19th and 20th centuries, are often several stories high and having a glazed roof and/or large windows, and often located immediately beyond the main entrance doors (in the lobby).

Atria are a popular design feature because they give their buildings a "feeling of space and light". The atrium has become a key feature of many buildings in recent years. Atria are popular with building users, building designers and building developers. Users like atria because they create a dynamic and stimulating interior that provides shelter from the external environment while maintaining a visual link with that environment. Designers enjoy the opportunity to create new types of spaces in buildings, and developers see atria as prestigious amenities that can increase commercial value and appeal.Fire control is an important aspect of contemporary atrium design due to criticism that poorly designed atria could allow fire to spread to a building's upper stories more quickly.

Atrium (heart)

The atrium (plural: atria) is one of the two blood collection chambers of the heart. It was previously called the auricle, but that name has now been in use as being synonymous with the right or left atrial appendage. The atrium is a chamber in which blood enters the heart, as opposed to the ventricle, where it is pushed out of the organ. It has a thin-walled structure that allows blood to return to the heart. There is at least one atrium in animals with a closed circulatory system.

The atrium receives blood as it returns to the heart to complete a circulating cycle, whereas the ventricle pumps blood out of the heart to start a new cycle.

Structure

Humans have a four-chambered heart consisting of the right atrium, left atrium, right ventricle, and left ventricle. The atria, are the two upper chambers. The right atrium receives and holds deoxygenated blood from the superior vena cava, inferior vena cava, anterior cardiac veins and smallest cardiac veins and the coronary sinus, which it then sends down to the right ventricle (through the tricuspid valve) which in turn sends it to the pulmonary artery for pulmonary circulation. The left atrium receives the oxygenated blood from the left and right pulmonary veins, which it pumps to the left ventricle (through the mitral valve) for pumping out through the aorta for systemic circulation.

Myth

A myth is a traditional or legendary story, collection, or study. It is derived from the Greek word mythos (μῦθος), which simply means "story". Mythology can refer either to the study of myths, or to a body or collection of myths. A myth also can be a made up story to explain why something exists.

Academic usage

Generally associated with the academic fields of mythology, mythography or folkloristics, a myth can be a story involving symbols that are capable of multiple meanings. The body of a myth in any given culture usually includes a cosmogonical or creation myth, concerning the origins of the world, or how the world and its creatures came into existence. The active beings in myths are generally gods and goddesses, heroes and heroines or animals and plants. Most myths are set in a timeless past before recorded and critical history begins.

A myth is a sacred narrative in the sense that it holds religious or spiritual significance for those who tell it. Myths also contribute to and express systems of thoughts and values. Use of the term by scholars implies neither the truth nor the falseness of the narrative. To the source culture, however, a myth by definition is "true", in that it embodies beliefs, concepts and ways of questioning to make sense of the world.

Myth (series)

Myth is a series of real-time tactics video games for Microsoft Windows and Mac OS. The games are:

Myth was developed by Bungie and published in 1997 by Eidos in Europe and Bungie in North America. Myth II was also developed by Bungie and self-published in North America in 1998. It was published by GT Interactive Software in Europe. As a result of Bungie's sale to Microsoft in 2000, the company lost the franchise rights to Take-Two Interactive.Myth III: The Wolf Age was developed by MumboJumbo and published by Take-Two in 2001.

All three games have received good reviews, especially the first and second game. Although the third game also received a generally positive reception, many reviewers cited a number of bugs in the initial release, and there was a general feeling that Take-Two had not given MumboJumbo enough time to complete the game.

The Myth games are categorized as real-time tactics, representing a departure from established real-time strategy titles such as Warcraft and Command & Conquer; resource micromanagement and the gradual building up of armies are not part of the gameplay, which instead focuses entirely on squad and soldier-level tactics. Some critics have argued that this style of gameplay allows the games a far greater sense of realism than their real-time strategy contemporaries.
