Context: Cheese is a food derived from milk that is produced in a wide range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk, usually the milk of cows, buffalo, goats, or sheep. During production, the milk is usually acidified, and adding the enzyme rennet causes coagulation. The solids are separated and pressed into final form. Some cheeses have molds on the rind or throughout. Most cheeses melt at cooking temperature., Milk is a pale liquid produced by the mammary glands of mammals. It is the primary source of nutrition for infant mammals (including humans who breastfeed) before they are able to digest other types of food. Early-lactation milk contains colostrum, which carries the mother's antibodies to its young and can reduce the risk of many diseases. It contains many other nutrients including protein and lactose., Rennet is a complex of enzymes produced in the stomachs of ruminant mammals. Chymosin, its key component, is a protease enzyme that curdles the casein in milk. This helps young mammals digest their mothers' milk. Rennet can also be used to separate milk into solid curds for cheesemaking and liquid whey. In addition to chymosin, rennet contains other important enzymes such as pepsin and a lipase., The domestic goat ("Capra aegagrus hircus") is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe., In computer science, ACID ("Atomicity, Consistency, Isolation, Durability") is a set of properties of database transactions. In the context of databases, a single logical operation on the data is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction., The sheep ("Ovis aries") is a quadrupedal, ruminant mammal typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Although the name "sheep" applies to many species in the genus "Ovis", in everyday usage it almost always refers to "Ovis aries". Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female sheep is referred to as a "ewe", an intact male as a "ram" or occasionally a "tup", a castrated male as a "wether", and a younger sheep as a "lamb"., A grater ( also known as a shredder ) is a kitchen utensil used to grate foods into fine pieces . It was invented by François Boullier in the 1540s , originally to grate cheese ., Proteins (or ) are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity., A kitchen utensil is a hand-held, typically small tool or utensil that is used in the kitchen, for food-related functions. A cooking utensil is a utensil used in the kitchen for cooking. Other names for the same thing, or subsets thereof, derive from the word "ware", and describe kitchen utensils from a merchandising (and functional) point of view: kitchenware, wares for the kitchen; ovenware and bakeware, kitchen utensils that are for use inside ovens and for baking; cookware, merchandise used for cooking; and so forth., Fat is one of the three main macronutrients, along with carbohydrate and protein. Fats, also known as triglycerides, are esters of three fatty acid chains and the alcohol glycerol., Enzymes are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process upon which enzymes may act are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. The set of enzymes made in a cell determines which metabolic pathways occur in that cell. The study of enzymes is called "enzymology"., Casein (or , from Latin "caseus", "cheese") is the name for a family of related phosphoproteins (S1, S2, , ). These proteins are commonly found in mammalian milk, making up 80% of the proteins in cow's milk and between 20% and 45% of the proteins in human milk.
Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive, to a binder for safety matches. As a food source, casein supplies amino acids, carbohydrates, and the two inorganic elements calcium and phosphorus., A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools., A mold (US) or mould is a fungus that grows in the form of multicellular filaments called "hyphae". In contrast, fungi that can adopt a single-celled growth habit are called yeasts., Subject: grater, Relation: subclass_of, Options: (A) alcohol (B) amino acid (C) being (D) calcium (E) carbohydrate (F) cheese (G) coagulation (H) computer (I) cooking (J) dna (K) fat (L) female (M) food (N) goat (O) growth (P) habit (Q) human (R) key (S) kitchen utensil (T) latin (U) liquid (V) location (W) milk (X) mold (Y) name (Z) order ([) ovis aries (\) pale (]) pathways (^) process (_) protein (`) rates (a) science (b) sequence (c) set (d) single (e) solid (f) species (g) study (h) temperature (i) tool (j) transfer (k) variety (l) word

Context: Symphonic metal is a subgenre of metal music which combines the characteristics of this genre, such as heavy drums and guitars, with different elements of classical music including symphonic instruments, choirs and on occasion, a full symphony orchestra. Keyboards reminiscent of power metal also often find a dominant place in this subgenre.
Symphonic metal bands often feature classically trained female vocalists, giving rise to the nickname opera metal or operatic metal, and it is not uncommon for them to feature a second vocalist performing growls, a more common characteristic of gothic metal.
Perhaps the most typical and prominent examples of symphonic metal bands are Finnish band Nightwish, Dutch bands Within Temptation, Delain and Epica, and Swedish band Therion, all four of which place a large focus on elements prevalent in film scores on top of the more basic classical components utilized more widely in the genre., Black metal is an extreme subgenre and subculture of heavy metal music. Common traits include fast tempos, a shrieking vocal style, heavily distorted guitars played with tremolo picking, raw (lo-fi) recording, unconventional song structures, and an emphasis on atmosphere. Artists often appear in corpse paint and adopt pseudonyms., Lake of Sorrow is the debut studio album by the Norwegian gothic metal band The Sins of Thy Beloved . It was recorded at Sound Suite Studio in August , 1998 and released the same year through Napalm Records ., Gothic metal (or goth metal) is a fusion genre combining the heaviness of heavy metal with the dark atmospheres of gothic rock. The music of gothic metal is diverse with bands known to adopt the gothic approach to different styles of heavy metal music. The genre originated during the early 1990s in Europe originally as an outgrowth of death-doom, a fusion of death metal and doom metal. Lyrics are generally dark and introspective with inspiration from gothic fiction as well as personal experiences., Gothic fiction, which is largely known by the subgenre of Gothic horror, is a genre or mode of literature and film that combines fiction and horror, death, and at times romance. Its origin is attributed to English author Horace Walpole, with his 1764 novel "The Castle of Otranto", subtitled (in its second edition) "A Gothic Story." The effect of Gothic fiction feeds on a pleasing sort of terror, an extension of Romantic literary pleasures that were relatively new at the time of Walpole's novel. It originated in England in the second half of the 18th century and had much success in the 19th, as witnessed by Mary Shelleys "Frankenstein" and the works of Edgar Allan Poe. Another well known novel in this genre, dating from the late Victorian era, is Bram Stokers "Dracula". The name "Gothic" refers to the (pseudo)-medieval buildings, emulating Gothic architecture, in which many of these stories take place. This extreme form of romanticism was very popular in England and Germany. The English Gothic novel also led to new novel types such as the German "Schauerroman" and the French "Georgia"., Brant Bjork (born March 19, 1973) is an American musician, singer, songwriter, multi-instrumentalist, and producer from Palm Desert, California. He is perhaps best known as the drummer and founder of the influential Californian stoner rock band Kyuss. Bjork played in Vista Chino, along with former Kyuss vocalist John Garcia. Until October 2014 when Nick Oliveri announced that there was a falling out and that Bjork and Garcia would continue working on their solo projects. He is one of the more notable figures in the stoner rock and Palm Desert scenes., Gothic rock (also referred to as goth rock or simply goth) is a musical subgenre of post-punk and alternative rock that formed during the late 1970s. Gothic rock bands grew from the strong ties they had to the English punk rock and emerging post-punk scenes. Proto-gothic bands include Siouxsie and the Banshees, Joy Division, Bauhaus and the Cure., Power metal is a subgenre of heavy metal combining characteristics of traditional metal with speed metal, often within symphonic context. Generally, power metal is characterized by a more uplifting sound, instead of the heaviness and dissonance prevalent in styles such as doom metal and death metal. Power metal bands usually have anthem-like songs with fantasy-based subject matter and strong choruses, thus creating a theatrical, dramatic and emotionally "powerful" sound. The term was first used in the middle of the 1980s and refers to two different but related styles: the first pioneered and largely practiced in North America with a harder sound similar to speed metal, and a later more widespread and popular style based in Europe (especially Scandinavia, Germany, Greece and Italy), South America (especially Brazil and Argentina) and Japan, with a lighter, more melodic sound and frequent use of keyboards., Karma to Burn, sometimes known as K2B, is a desert rock/stoner rock band from Morgantown, West Virginia comprising guitarist William Mecum, bassist Eric Clutter, and drummer Evan Devine. The band are noted for their uncompromising, mostly instrumental sound., Doom metal is an extreme style of heavy metal music that typically uses slower tempos, low-tuned guitars and a much "thicker" or "heavier" sound than other metal genres. Both the music and the lyrics intend to evoke a sense of despair, dread, and impending doom. The genre is strongly influenced by the early work of Black Sabbath, who formed a prototype for doom metal with songs such as "Black Sabbath", "Children of the Grave", "Electric Funeral" and "Into the Void". During the first half of the 1980s, a number of bands from England (Pagan Altar, Witchfinder General), the United States (Pentagram, Saint Vitus, Trouble) and Sweden (Candlemass, Count Raven) defined doom metal as a distinct genre., Abigor is an Austrian atmospheric black metal band formed in 1993. They are named after an upper demon of war in Christian demonology., Metalcore is a broad fusion genre of extreme metal and hardcore punk. The word is a blend of the names of the two genres. Among other genres blending metal and hardcore, such as crust punk and grindcore, metalcore is noted for its use of breakdowns, which are slow, intense passages that are conducive to moshing. Pioneering metalcore bandssuch as Integrity, Earth Crisis and Converge, all of which had formed by 1990are described as leaning more toward hardcore, with their style sometimes being called metallic hardcore, whereas later bandssuch as Killswitch Engage, All That Remains, As I Lay Dying, Bullet for My Valentine, and Parkway Drive are described as leaning more towards metal. Pantera (who influenced Trivium, Atreyu, Bleeding Through and Unearth) and Sepultura have been particularly influential to the development of metalcore in the 2000s, which saw many bands in the genre achieve considerable commercial success., Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking, deep growling vocals and screams, aggressive, powerful drumming featuring double kick or blast beat techniques, minor keys or atonality, abrupt tempo, key, and time signature changes and chromatic chord progressions. The lyrical themes of death metal may invoke slasher film-stylized violence, religion (sometimes Satanism), occultism, Lovecraftian horror, nature, mysticism, mythology, philosophy, science fiction, and politics, and they may describe extreme acts, including mutilation, dissection, torture, rape, cannibalism, and necrophilia., Vintersorg ("Winter Sorrow" in English) is a Swedish band from Skellefteå, formed in 1994 under the name Vargatron (Wolfthrone in English). Musically, Vintersorg has covered a wide number of heavy metal genres; while the band is mostly rooted in extreme metal styles, particularly black metal and Viking/folk metal, it has also expanded into progressive metal and avant-garde metal. Lyrically, the band deals with topics on fantasy, mythology, nature, the cosmos, and metaphysics. Vintersorg means "Winter Sorrow," but the name was taken from The Legend of the Ice People series by Margit Sandemo, where the character Vintersorg is the son of a great pagan leader., The Sins of Thy Beloved was a Death-doom/gothic metal band from Bryne, Norway, founded in 1996., Falkenbach is a viking metal group from Germany that is signed to "Prophecy Productions". The name means ""Falconbrook"" in German. The one permanent member is Vratyas Vakyas (real name Markus Tümmers). They are one of the very first Viking metal bands, starting in 1989, with their first release that same year., Folk metal is a fusion genre of heavy metal music and traditional folk music that developed in Europe during the 1990s. It is characterised by the widespread use of folk instruments and, to a lesser extent, traditional singing styles (for example, Dutch Heidevolk, Danish Sylvatica and Spanish Stone of Erech). It also sometimes features soft instrumentation influenced by folk rock., Monster Magnet is an American stoner rock band. Hailing from Red Bank, New Jersey, the group was founded by Dave Wyndorf (vocals and guitar), John McBain (guitar) and Tim Cronin (vocals and drums). The band first went by the names "Dog of Mystery", "Airport 75", "Triple Bad Acid" and "King Fuzz" before finally settling on "Monster Magnet", taken from the name of a 1960s toy made by Wham-O, which Wyndorf liked when he was a child.<ref name="http://www.monstermagnet.net/bio.htm"></ref>, Death-doom is an extreme subgenre of heavy metal. It combines the slow tempos and pessimistic or depressive mood of doom metal with the deep growling vocals and double kick drumming of death metal. The genre emerged in the mid-1980s and gained a certain amount of popularity during the 1990s, but had become less common by the turn of the 21st century. In turn, death/doom gave rise to the closely related genre of funeral doom as well as to the more melodic and romantic gothic metal., Napalm Records is an Austrian independent record label focused on heavy metal and hard rock. Originally, Napalm focused mainly on black metal bands such as Abigor and Summoning and folk metal bands such as Falkenbach and Vintersorg. Later on, the label expanded its roster by adding gothic metal, symphonic metal, power metal, doom metal, and metalcore bands, as well as stoner rock acts Monster Magnet, Karma to Burn, and Brant Bjork. Napalm has its own publishing house named Iron Avantgarde Publishing., Stoner rock or stoner metal is a musical subgenre which combines elements of heavy metal, psychedelic rock, acid rock, doom metal, and blues rock. The term desert rock is often used interchangeably with the term "stoner rock" to describe this genre; however, not all stoner rock bands would fall under the descriptor of "desert rock." Stoner rock is typically slow-to-mid tempo and features a heavily distorted, groove laden bass-heavy sound, melodic vocals, and "retro" production. The genre emerged during the early-1990s and was pioneered foremost by the Californian bands Kyuss and Sleep., Hard rock is a loosely defined subgenre of rock music that began in the mid-1960s, with the garage, psychedelic and blues rock movements. It is typified by a heavy use of aggressive vocals, distorted electric guitars, bass guitar, drums, and often accompanied with pianos and keyboards., Subject: lake of sorrow, Relation: genre, Options: (A) acid rock (B) atonality (C) black metal (D) child (E) classical music (F) crust punk (G) death metal (H) doom metal (I) extreme metal (J) fantasy (K) folk metal (L) fusion (M) gothic fiction (N) gothic metal (O) gothic rock (P) grindcore (Q) hard rock (R) hardcore punk (S) heavy metal (T) instrumental (U) legend (V) literature (W) lovecraftian horror (X) march (Y) metalcore (Z) music ([) musical (\) mystery (]) opera (^) orchestra (_) politics (`) power metal (a) progressive metal (b) prophecy (c) religion (d) rock (e) romantic (f) science (g) science fiction (h) song (i) speed metal (j) symphonic metal (k) symphony (l) terror (m) viking metal (n) war

Context: A 3270 Emulator is a terminal emulator that duplicates the functions of an IBM 3270 mainframe computer terminal on a PC or similar microcomputer., A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and minimal input/output (I/O) circuitry mounted on a single printed circuit board. Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense)., Irma board , originally spelled IRMA board , refers to a brand of coaxial interface cards for PCs and Macintosh computers used to enable 3270 emulator programs to connect to IBM mainframe computers . IRMA boards were invented by Technical Analysis Corp. ( TAC ) , acquired by Digital Communications Associates , Inc. ( DCA ) who manufactured and marketed the Irma products from 1982 on . DCA of Alpharetta , Georgia , was acquired in 1994 by Attachmate Corporation of Bellevue , Washington . A board with all the capabilities of that which would eventually be called IRMA was originally developed in - house by Amdahl Corp in 1977 , but it was not actively marketed by Amdahl ., The IBM 3270 is a class of block oriented computer terminal (sometimes called "display devices") introduced by IBM in 1971 normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. Due to the text colour on the original models, these terminals are informally known as "green screen" terminals. Unlike a character-oriented terminal, the 3270 minimizes the number of I/O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable., A terminal emulator, terminal application, term, or tty for short, is a program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term "terminal" covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window., Mainframe computers (colloquially referred to as "big iron") are computers used primarily by large organizations for critical applications, bulk data processing, such as census, industry and consumer statistics, enterprise resource planning, and transaction processing., Subject: irma board, Relation: instance_of, Options: (A) application (B) architecture (C) central processing unit (D) class (E) computer terminal (F) data (G) day (H) emulator (I) enterprise (J) graphical user interface (K) industry (L) interface (M) mainframe computer (N) microcomputer (O) printed circuit board (P) sense (Q) system (R) term (S) terminal emulator (T) video (U) window
