Caldera

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.

Etymology

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.

Caldera formation

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

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.

Novell Corsair

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 (film)

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.

Plot

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.

Toba (Nova Crnja)

Toba (Serbian Cyrillic: Тоба, Hungarian: Tóba) is a village in Serbia. It is situated in the Nova Crnja municipality, in the Central Banat District, Vojvodina province. The village has a Hungarian ethnic majority (84.08%) and its population numbering 691 people (2002 census).

History

The Field Marshal, Count Robert Zichy-Ferraris from the prominent Hungarian family of Zichy, established the settlement of the Toba in 1789. During the first half or 19th century, Zichy sold his property to Henry, Count of Chambord, pretender to the throne of France. Henry appointed Barron Cyril Billet as his governor. Baron Billet and his sons were managing property for approximately 50 years. During that period, they were playing important role in the social life of the region. The castle, small family residential house and Roman Catholic Church of Holy Trinity were built during that period. By the mid-19th century, settlement was known as the Great Toba, and the population of the village mostly consisted of the tobacco growers. After the death of Henry, Robert I, Duke of Parma inherited his property. After Duke's death, his son Elias of Bourbon-Parma sold the property to the Bank of Timisoara. After the World War I, whole region, which was once part of the Austro-Hungarian Monarchy, become the part of newly formed Kingdom of Yugoslavia.
