A caldera is a cauldron-like volcanic feature on large central volcanoes, a special sort of volcanic crater (from one to several kilometers in diameter), formed when a magma chamber was emptied. The depression then originated either in very big explosive eruptions or in erosion and collapse of the magma chamber roof. The previous emptying of this magma chamber is often accomplished during a series of effusive eruptions in the volcanic system, even kilometers away from the magma chamber itself.
The word comes from Spanish caldera, and this from Latin caldaria, meaning "cooking pot". In some texts the English term cauldron is also used.The term caldera was introduced into the geological vocabulary by the German geologist Leopold von Buch when he published his memoirs of his 1815 visit to the Canary Islands, where he first saw the Las Cañadas caldera on Tenerife, with Montaña Teide dominating the landscape, and then the Caldera de Taburiente on La Palma.
A collapse is triggered by the emptying of the magma chamber beneath the volcano, sometimes as the result of a large explosive volcanic eruption (see Tambora in 1815), but also during effusive eruptions on the flanks of a volcano (see Piton de la Fournaise in 2007) or in a connected fissure system (see Bárðarbunga in 2014/15). If enough magma is ejected, the emptied chamber is unable to support the weight of the volcanic edifice above it. A roughly circular fracture, the "ring fault", develops around the edge of the chamber. Ring fractures serve as feeders for fault intrusions which are also known as ring dykes. Secondary volcanic vents may form above the ring fracture. As the magma chamber empties, the center of the volcano within the ring fracture begins to collapse. The collapse may occur as the result of a single cataclysmic eruption, or it may occur in stages as the result of a series of eruptions. The total area that collapses may be hundreds or thousands of square kilometers.
Caldera OpenLinux (COL) is a defunct Linux distribution that was originally introduced by Caldera in 1997 based on the German LST Power Linux distribution, and then taken over and further developed by Caldera Systems (now SCO Group) since 1998. A successor to the Caldera Network Desktop put together by Caldera since 1995, OpenLinux was an early "business-oriented distribution" and foreshadowed the direction of developments that came to most other distributions and the Linux community generally.
Corsair, a user interface for NetWare, was a project run by Novell corporation's Advanced Technology Group (ATG) between 1993 and 1995. Novell wanted an internet desktop and conducted research on how to better and more easily integrate and manage network access for users. Windows's own support for connecting to Novell networks would not be improved until later releases and the Internet was dominated by Unix-based operating systems. Relative to their needs, Novell deemed the Unixes of the day were too hardware intensive, too large, and charged too much in license fees.
Caldera is an 11-minute computer animated short film released in 2012. It was directed by Evan Viera, co-written by Chris Bishop, co-produced by Chris Perry, and created in conjunction with Bit Films, the computer animation incubator program at Hampshire College in Amherst, Massachusetts.
Caldera received a Prix Ars Electronica Award of Distinction in the Computer Animation category in 2012.
Caldera is about a young girl who goes off her medication and leaves a bleak metropolis to immerse herself in a vibrant oceanic cove. Ultimately, the story is about the young girl’s impossible predicament, where she can not live in either the fantastical and haunting world of psychosis or in the marginalizing society that mandates her medication.
The Byzantine Empire, sometimes referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern-day Istanbul, originally founded as Byzantium). It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm; its citizens continued to refer to their empire as the Roman Empire (Ancient Greek: Βασιλεία τῶν Ῥωμαίων, tr. Basileia tôn Rhōmaiōn; Latin: Imperium Romanum), or Romania (Ῥωμανία), and to themselves as "Romans".
Several events from the 4th to 6th centuries mark the period of transition during which the Roman Empire's Greek East and Latin West divided. Constantine I (r. 324–337) reorganised the empire, made Constantinople the new capital, and legalised Christianity. Under Theodosius I (r. 379–395), Christianity became the Empire's official state religion and other religious practices were proscribed. Finally, under the reign of Heraclius (r. 610–641), the Empire's military and administration were restructured and adopted Greek for official use instead of Latin. Thus, although the Roman state continued and Roman state traditions were maintained, modern historians distinguish Byzantium from ancient Rome insofar as it was centred on Constantinople, oriented towards Greek rather than Latin culture, and characterised by Orthodox Christianity.
Byzantine is a heavy metal band from Charleston, West Virginia that formed in 2000. The band consists of frontman and co-founder Chris "OJ" Ojeda (rhythm guitar and vocals), Brian Henderson (guitar), Matt Wolfe (drums) and Sean Sydnor (bass guitar). They have released three studio albums on Prosthetic Records and two independent albums. Byzantine is widely hailed as the most underrated band of the modern NWOAHM movement. Due to various circumstances, the band reported their split on January 26, 2008, one day after the release of their third album, but reunited in 2010. Byzantine is known for its unique sound and modern, "forward thinking" musical style, which explores different musical territories and song structures. On January 26, 2012 the band announced that it is recording a new album, 4 years after disbanding.
Byzantine formed in the spring of 2000 by bassist Chris "Cid" Adams, drummer Jeremy Freeman, guitarist Tony Rohrbough, and vocalist/guitarist Chris "OJ" Ojeda after their former bands New Family and Temper disbanded. Byzantine wrote four songs before Jeremy Freeman left. Seven more songs were written and 2000-2001 Demos was recorded and self-released in 2001. Byzantine became a part of the local West Virginia heavy metal scene.
Byzantine usually refers to the Roman Empire during the Middle Ages.
