Your Independent Grocer
Your Independent Grocer (YIG), known colloquially as "Independent" or "Yours" is a supermarket chain in Canada with more than 100 locations. It has stores in every province and territory except Manitoba, Nunavut, and Quebec. It is a unit of National Grocers, itself a unit of Loblaw Companies Limited. Stores are typically operated by a franchise owner. Many of the stores were originally Ottawa-area outlets of the defunct Quebec-based Steinberg's grocery chain. When Steinberg's was bought out by Metro Richelieu in 1992, the Ottawa-area franchises were spun off into the separate Your Independent Grocer chain. Many SaveEasy locations in Atlantic Canada became Your Independent Grocer locations between 2014 and 2016. In May 2018, select locations began delivery through Instacart.

YMCA Youth And Government
YMCA Youth and Government (YaG), also known as Youth In Government, or Model Legislature and Court, is a program of the YMCA of the USA that allows high school students to serve in model governments at the local, state, national, and international levels. The YMCA Youth and Government program currently operates in 49 states and Washington, DC. Each state may participate in the national programs, which include: the YMCA Youth Conference on National Affairs (CONA), YMCA National Judicial Competition, YMCA Youth Governors Conference (YGC), and YMCA Youth Advocate Program. History The YMCA Youth and Government program was established in 1936 in New York by Clement A. Duran, then the Boys Work Secretary for the Albany YMCA. The program motto, “Democracy must be learned by each generation,” was taken from a quote by Earle T. Hawkins, the founder of the Maryland Youth and Government program.

Yttrium Iron Garnet
Yttrium iron garnet (YIG) is a kind of synthetic garnet, with chemical composition , or Y3Fe5O12. It is a ferrimagnetic material with a Curie temperature of 560 K. YIG may also be known as yttrium ferrite garnet, or as iron yttrium oxide or yttrium iron oxide, the latter two names usually associated with powdered forms. In YIG, the five iron(III) ions occupy two octahedral and three tetrahedral sites, with the yttrium(III) ions coordinated by eight oxygen ions in an irregular cube. The iron ions in the two coordination sites exhibit different spins, resulting in magnetic behavior. By substituting specific sites with rare-earth elements, for example, interesting magnetic properties can be obtained. YIG has a high Verdet constant which results in the Faraday effect, high Q factor in microwave frequencies, low absorption of infrared wavelengths down to 1200 nm, and very small linewidth in electron spin resonance. These properties make it useful for MOI ( magneto optical i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
YIG Sphere
Yttrium iron garnet spheres (YIG spheres) serve as magnetically tunable filters and resonators for microwave frequencies. YIG filters are used for their high Q factors, typically between 100 and 200. A sphere made from a single crystal of synthetic yttrium iron garnet acts as a resonator. The field from an electromagnet changes the resonance frequency of the sphere and hence the frequency it will allow to pass. The advantage of this type of filter is that the garnet can be tuned over a very wide frequency range by varying the strength of the magnetic field. Some filters can be tuned from 3 GHz up to 50 GHz. Construction The YIG spheres themselves are on the order of 0.5 mm in diameter and are manufactured from slightly larger cubes of diced material by tumbling, as is done in the manufacture of jewelry. The garnet is mounted on a ceramic rod, and a pair of small loops around the sphere couple fields into and out of the sphere; the loops are half-turns, posi ...

The Curse Of Yig
"The Curse of Yig" is a short story by H. P. Lovecraft and Zealia Bishop in which Yig, "The Father of Serpents", is first introduced. Plot In 1889, upon arriving in Oklahoma, a couple learn about local legends surrounding a "snake god" called Yig, which takes vengeance on anyone who kills a serpent by either killing them or turning them into a half-snake monster. The husband has an intense fear of snakes, and his wife kills a nest of rattlesnakes at one of their campsites. The husband is horrified by the thought that Yig will take vengeance. After building their cabin, the husband is insistent on practicing various rituals from the native tribes to keep Yig away, grating heavily on his wife's nerves. In fear, the woman kills her own husband in the dark, thinking he is Yig. She is taken to an asylum, and dies there... but not before giving birth to four half-snake creatures. Background Bishop supplied the story idea and some notes, paying Lovecraft to flesh it out in 1928. Bish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
