Futurism (Christianity)
Futurism is a Christian eschatological view that interprets portions of the Book of Revelation, the Book of Ezekiel, and the Book of Daniel as future events in a literal, physical, apocalyptic, and global context. By comparison, other Christian eschatological views interpret these passages as past events in a symbolic, historic context (Preterism and Historicism), or as present-day events in a non-literal and spiritual context (Idealism). Futurist beliefs usually have a close association with Premillennialism and Dispensationalism.

OFFSystem
The Owner-Free File System (OFF System, or OFFS for short) is a peer-to-peer distributed file system in which all shared files are represented by randomized multi-used data blocks. Instead of anonymizing the network, the data blocks are anonymized and therefore, only data garbage is ever exchanged and stored and no forwarding via intermediate nodes is required. OFFS claims to have been created with the expressed intention "to cut off some gangrene-infested bits of the copyright industry."

Centaur (Minor Planet)
Centaurs are small solar system bodies with a semi-major axis between those of the outer planets. They generally have unstable orbits because they cross or have crossed the orbits of one or more of the giant planets; almost all their orbits have dynamic lifetimes of only a few million years, but there is one centaur, (514107) 2015 BZ509, which may be in a stable (though retrograde) orbit. Centaurs typically behave with characteristics of both asteroids and comets. They are named after the mythological centaurs that were a mixture of horse and human. It has been estimated that there are around 44,000 centaurs in the Solar System with diameters larger than 1 kilometer. The first centaur to be discovered, under the definition of the Jet Propulsion Laboratory and the one used here, was 944 Hidalgo in 1920. However, they were not recognized as a distinct population until the discovery of 2060 Chiron in 1977. The largest confirmed centaur is 10199 Chariklo, which at 260 kilometers in diameter is as big as a mid-sized main-belt asteroid, and is known to have a system of rings. It was discovered in 1997. However, the lost centaur 1995 SN55 may be somewhat larger. No centaur has been photographed up close, although there is evidence that Saturn's moon Phoebe, imaged by the Cassini probe in 2004, may be a captured centaur that originated in the Kuiper belt. In addition, the Hubble Space Telescope has gleaned some information about the surface features of 8405 Asbolus. (As of 2008), three centaurs have been found to display comet-like comas: 2060 Chiron, 60558 Echeclus, and 166P/NEAT. Chiron and Echeclus are therefore classified as both asteroids and comets. Other centaurs, such as 52872 Okyrhoe, are suspected of having shown comas. Any centaur that is perturbed close enough to the Sun is expected to become a comet.

Meic Torcaill
The Meic Torcaill, also known as the Meic Turcaill, the Mac Torcaill dynasty, and the Mac Turcaill dynasty, were a leading Norse-Gaelic family in mediaeval Dublin. The kindred produced several eminent men and kings of Dublin before the English conquest of the kingdom in 1170. Afterwards the family fell from prominence, losing possession of their extensive lands in the region. In time the Meic Torcaill lost precedence to other Dublin families, such as the Harolds and Archbolds.

Surya Namaskar
Surya Namaskar (Sanskrit: सूर्यनमस्कार IAST: Sūrya Namaskāra), Salute to the Sun or Sun Salutation, is a practice in yoga as exercise incorporating a flow sequence of some twelve gracefully linked asanas. The asana sequence was first recorded as yoga in the early 20th century, though similar exercises were in use in India before that, for example among wrestlers. The basic sequence involves moving from a standing position into Downward and Upward Dog poses and then back to the standing position, but many variations are possible. The set of 12 asanas is dedicated to the solar deity Surya. In some Indian traditions, the positions are each associated with a different mantra. The precise origins of Surya Namaskar are uncertain, but the sequence was made popular in the early 20th century by Bhawanrao Shriniwasrao Pant Pratinidhi, the Rajah of Aundh, and adopted into yoga by Krishnamacharya in the Mysore Palace, where the Surya Namaskar classes, not then considered to be yoga, were held next door to his yogasala. Pioneering yoga teachers taught by Krishnamacharya, including Pattabhi Jois and B. K. S. Iyengar, taught transitions between asanas derived from Surya Namaskar to their pupils worldwide. Variant yoga sequences such as those called Chandra Namaskar (Moon Salutation) have been created based on the original sequence taught by Pant Pratinidhi.

Life and Death
Life and death (死活) is a fundamental concept in the game of Go, where the status of a distinct group of stones is determined as either being "alive", where they may remain on the board indefinitely, or "dead," where the group will be lost as "captured". The basic idea can be summarized by:

Black Sea Climate and Ecology
Short-term climatic variation in the Black Sea region is significantly influenced by the operation of the North Atlantic oscillation, the climatic mechanisms resulting from the interaction between the north Atlantic and mid-latitude air masses. While the exact mechanisms causing the North Atlantic Oscillation remain unclear, it is thought the climate conditions established in western Europe mediate the heat and precipitation fluxes reaching Central Europe and Eurasia, regulating the formation of winter cyclones, which are largely responsible for regional precipitation inputs and influence Mediterranean Sea surface temperatures (SST's). The relative strength of these systems also limits the amount of cold air arriving from northern regions during winter. Other influencing factors include the regional topography, as depressions and storms systems arriving from the Mediterranean are funneled through the low land around the Bosporus, Pontic and Caucasus mountain ranges acting as waveguides, limiting the speed and paths of cyclones passing through the region.

Compounds of Zinc
Compounds of zinc are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript behavior, they are generally colorless (unlike other elements with the oxidation number +2, which are usually white), do not readily engage in redox reactions, and generally adopt symmetrical structures.
