Light Rail
Light rail (or light rail transit, abbreviated to LRT) is a form of passenger urban rail transit that uses rolling stock derived from tram technology National Conference of the Transportation Research Board while also having some features from heavy rapid transit. The term was coined in 1972 in the United States as an English equivalent for the German word ''Stadtbahn'', meaning "city railway". From: 9th National Light Rail Transit Conference Different definitions exist in some countries, but in the United States, light rail operates primarily along exclusive Right_of_way#Rail_right_of_way, rights-of-way and uses either individual tramcars or multiple units coupled together, with a lower capacity and speed than a long heavy rail passenger train or rapid transit system. Narrowly defined, light rail transit uses rolling stock that is similar to that of a traditional tram, while operating at a higher capacity and speed, often on an exclusive right-of-way. In broader usage, light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latvijas Radio
Latvijas Radio (shortened LR; literally "Latvia's Radio") is Latvia's national public-service radio broadcasting network.

Legislative Route
In the United States, a legislative route (LR) or legislative highway is a highway defined by law Law is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior, with its precise definition a matter of longstanding debate. It has been variously described as a science and as the ar ...s passed in a U.S. state, 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 Legislative route (Minnesota), constitutional routes.

Ringer's Lactate Solution
Ringer's lactate solution (RL), also known as sodium lactate solution, Lactated Ringer's (LR), and Hartmann's solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water. It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure. It may also be used to treat metabolic acidosis and to wash the eye following a chemical burn. It is given by intravenous infusion or applied to the affected area. Side effects may include allergic reactions, high blood potassium, hypervolemia, and high blood calcium. It may not be suitable for mixing with certain medications and some recommend against use in the same infusion as a blood transfusion. Ringer's lactate solution has a lower rate of acidosis as compared with normal saline. Use is generally safe in pregnancy and breastfeeding. Ringer's lactate solution is in the crystalloid family of medications. It is isotonic, i.e. it has the same ton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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"), or to be in ''abundance''. 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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
22 Long Rifle
The .22 long rifle, also known as the .22 LR or 5.7×15mmR, is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of firearms including rifles, pistols, revolvers, and submachine guns. In terms of units sold, it is by far the most common ammunition that is manufactured and sold in the world. Common uses include hunting and shooting sports. Ammunition produced in .22 long rifle is effective at short ranges, has little recoil, and is inexpensive to purchase. These qualities make it ideal for plinking and marksmanship training. History American cartridge 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, render ...

Lawrencium
Lawrencium is a synthetic chemical element; it has symbol Lr (formerly Lw) and atomic number 103. It is named after Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements. A radioactive metal, lawrencium is the eleventh transuranium element, the third transfermium, 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 homolog to lutetium in the periodic table, and is a trivalent element. It thus could also be classified as the first of the 7th-period transition metals. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L(R)
In set theory, L(R) (pronounced ''L of R'') is the smallest transitive class, transitive inner model of Zermelo–Fraenkel set theory, ZF containing all the ordinal number, ordinals and all the real number, reals. Construction L(R) can be constructed in a manner analogous to the construction of Gödel's constructible universe, L, 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 real ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The ARMv7 architecture uses general-purpose register R14 as the link register, OpenRISC uses register r9, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
