The superconducting properties of YBa 2 Cu 3 O 7−x are sensitive to the value of x, its oxygen content. Only those materials with 0 ≤ x ≤ 0.65 are superconducting below T c , and when x ~ 0.07 , the material superconducts at the highest temperature of 95 K , [ 6 ] or in highest magnetic fields: 120 T for B perpendicular and 250 T for B ...
Yttrium is a key ingredient in the yttrium barium copper oxide (YBa 2 Cu 3 O 7, aka 'YBCO' or '1-2-3') superconductor developed at the University of Alabama in Huntsville and the University of Houston in 1987. [49] This superconductor is notable because the operating superconductivity temperature is above liquid nitrogen's boiling point (77.1 K ...
The lib directory contains the code for the gem. The test (or spec) directory is used for testing. Rakefile is used by Rake to automate tests and to generate code. README includes the documentation, RDOC, for most gems. Gem specification (gemspec) contains information about the author of the gem, the time of creation and the purpose the gem serves.
YBA or yba can refer to a number of things: Young British Artists, a movement of British artists in the 1980s and 1990s; Yala language, a language spoken in Ogoja, Nigeria, by ISO 639 code; Young Buddhist Association, an association of Buddhists in the U.S. Banff Airport, an airstrip near Banff, Alberta, Canada, by IATA code
2 O 3). Many gems are crystals which are classified by their crystal system such as cubic or trigonal or monoclinic. Another term used is habit, the form the gem is usually found in. [12] For example, diamonds, which have a cubic crystal system, are often found as octahedrons. [13] Gemstones are classified into different groups, species, and ...
Many of the YBA artists graduated from the BA Fine Art course at Goldsmiths, in the late 1980s, whereas some from the group had trained at Royal College of Art. [ 2 ] The scene began around a series of artist-led exhibitions held in warehouses and factories, beginning in 1988 with the Damien Hirst-led Freeze and, in 1990, East Country Yard Show ...
Blocksworld also implemented community moderation; newly published worlds had to get "approved", and members of the community could "moderate" pending worlds by simply playtesting the world and approving or rejecting it. Another feature, the Prize Wheel, allowed players to spin a wheel and get a new block, texture, etc.
Mock-up image of opening a loot box in a video game. In video game terminology, a loot box (also called a loot crate or prize crate) is a consumable virtual item which can be redeemed to receive a randomised selection of further virtual items, or loot, ranging from simple customisation options for a player's avatar or character to game-changing equipment such as weapons and armour.
