GenoCAD-Theoretical foundation-GenoCAD is rooted in the theory of formal languages; in particular, the design rules describing how to combine different kinds of parts and form context-free grammars. | milkshake721/2.1M-wiki-STEM |
GenoCAD-Theoretical foundation-A context free grammar can be defined by its terminals, variables, start variable and substitution rules. In GenoCAD, the terminals of the grammar are sequences of DNA that perform a particular biological purpose (e.g. a promoter). The variables are less homogeneous: they can represent lo... | milkshake721/2.1M-wiki-STEM |

Pig iron-History-The phase transition of the iron into liquid in the furnace was an avoided phenomenon, as decarburizing the pig iron into steel was an extremely tedious process using medieval technology. | milkshake721/2.1M-wiki-STEM |
Pig iron-Uses-Traditionally, pig iron was worked into wrought iron in finery forges, later puddling furnaces, and more recently, into steel. In these processes, pig iron is melted and a strong current of air is directed over it while it is stirred or agitated. This causes the dissolved impurities (such as silicon) to b... | milkshake721/2.1M-wiki-STEM |
Pig iron-Uses-Modern uses Until recently, pig iron was typically poured directly out of the bottom of the blast furnace through a trough into a ladle car for transfer to the steel mill in mostly liquid form; in this state, the pig iron was referred to as hot metal.

The use of a white background and lights of incremental brightness is called "white-on-white" perimetry. This type of perimetry is... | milkshake721/2.1M-wiki-STEM |
Visual field test-Perimetry-Microperimetry Microperimetry assesses the macular function in a similar way to perimetry. However, fundus imaging is performed at the same time. This allows for fundus tracking to ensure accurate stimulus placement. Thus, microperimetry provides enhances the retest reliability, enables prec... | milkshake721/2.1M-wiki-STEM |
Visual field test-Methods of stimulus presentation-Static perimetry Static perimetry tests different locations throughout the field one at a time. First, a dim light is presented at a particular location. If the patient does not see the light, it is made gradually brighter until it is seen. The minimum brightness requi... | milkshake721/2.1M-wiki-STEM |
