Legislative Route
In the United States, a legislative route (LR) or legislative highway is a highway defined by laws passed in a state legislature. The numbering of such highways may or may not correspond to the numbers familiar to the public as part of the state, U.S. highway, and Interstate highway systems. Legislative routes may be composed of several such roads, and conversely, state, U.S., and Interstate highways may be made up of several legislative routes. Minnesota also had highways defined in an amendment to the Minnesota State Constitution in 1920, and those roads are known as constitutional route In the U.S. state of Minnesota, a legislative route is a highway number defined by the Minnesota State Legislature. The routes from 1 to 70 are constitutional routes, defined as part of the Babcock Amendment to the Minnesota State Constitution, p ...s. References Roads in the United States {{US-road-stub ...

Limiting Reagent
The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. The amount of product formed is limited by this reagent, since the reaction cannot continue without it. If one or more other reagents are present in excess of the quantities required to react with the limiting reagent, they are described as ''excess reagents'' or ''excess reactants'' (sometimes abbreviated as "xs"). The limiting reagent must be identified in order to calculate the percentage yield of a reaction since the theoretical yield is defined as the amount of product obtained when the limiting reagent reacts completely. Given the balanced chemical equation, which describes the reaction, there are several equivalent ways to identify the limiting reagent and evaluate the excess quantities of other reagents. Method 1: Comparison of reactant amounts This method is most useful when there are only two reactants. On ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
22 Long Rifle
The .22 Long Rifle or simply .22 LR or 22 (metric designation: 5.6×15mmR) is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of rifles, pistols, revolvers, smoothbore shotguns, and submachine guns. In terms of units sold it is by far the most common ammunition in the world today. Common uses include hunting and shooting sports. Ammunition produced in .22 Long Rifle is effective at short ranges, has little recoil, and is cheap to purchase, making it ideal for training. History American firearms manufacturer J. Stevens Arms & Tool Company introduced the .22 Long Rifle cartridge in 1887. The round owes its origin to the .22 BB Cap of 1845 and the .22 Short of 1857. It combined the case of the .22 Long of 1871 with a bullet, giving it a longer overall length, a higher muzzle velocity and superior performance as a hunting and target round, rendering the .22 Extra Long cartridges obsolete. The .22 LR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawrencium
Lawrencium is a synthetic chemical element with the symbol Lr (formerly Lw) and atomic number 103. It is named in honor of Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements. A radioactive metal, lawrencium is the eleventh transuranic element and the last member of the actinide series. Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding lighter elements with charged particles. Fourteen isotopes of lawrencium are currently known; the most stable is 266Lr with half-life 11 hours, but the shorter-lived 260Lr (half-life 2.7 minutes) is most commonly used in chemistry because it can be produced on a larger scale. Chemistry experiments confirm that lawrencium behaves as a heavier homology (chemistry), homolog to lutetium in the periodic table, and is a valence (chemistry), trivalent element. It thus could also be classified as the first of the 7th-period tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L(R)
In set theory, L(R) (pronounced L of R) is the smallest transitive inner model of ZF containing all the ordinals and all the reals. Construction It can be constructed in a manner analogous to the construction of L (that is, Gödel's constructible universe), by adding in all the reals at the start, and then iterating the definable powerset operation through all the ordinals. Assumptions In general, the study of L(R) assumes a wide array of large cardinal axioms, since without these axioms one cannot show even that L(R) is distinct from L. But given that sufficient large cardinals exist, L(R) does not satisfy the axiom of choice, but rather the axiom of determinacy. However, L(R) will still satisfy the axiom of dependent choice, given only that the von Neumann universe, ''V'', also satisfies that axiom. Results Given the assumptions above, some additional results of the theory are: * Every projective set of reals – and therefore every analytic set and every Borel set of reals ...

Link Register
A link register (LR for short) is a register which holds the address to return to when a subroutine call completes. This is more efficient than the more traditional scheme of storing return addresses on a call stack, sometimes called a machine stack. The link register does not require the writes and reads of the memory containing the stack which can save a considerable percentage of execution time with repeated calls of small subroutines. The IBM POWER architecture, and its PowerPC and Power ISA successors, have a special-purpose link register, into which subroutine call instructions put the return address. In some other instruction sets, such as the ARM architectures, SPARC, and OpenRISC, subroutine call instructions put the return address into a specific general-purpose register, so that register is designated by the instruction set architecture as the link register. In some others, such as PA-RISC, RISC-V, and the IBM System/360 and its successors, including z/Architecture, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lexical Resource
In digital lexicography, natural language processing, and digital humanities, a lexical resource is a language resource consisting of data regarding the lexemes of the lexicon of one or more languages e.g., in the form of a database. Characteristics Different standards for the machine-readable edition of lexical resources exist, e.g., Lexical Markup Framework (LMF) an ISO standard for encoding lexical resources, comprising an abstract data model and an XML serialization, and OntoLex-Lemon, an RDF vocabulary for publishing lexical resources as knowledge graphs on the web, e.g., as Linguistic Linked Open Data. Depending on the type of languages that are addressed, a lexical resource may be qualified as monolingual, bilingual or multilingual. For bilingual and multilingual lexical resources, the words may be connected or not connected from one language to another. When connected, the equivalence from a language to another is performed through a bilingual link (for bilingual lexi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
