:''"CFYK-FM" was the previous call sign for what is now CBNY-FM, a repeater of CBU-FM Vancouver.'' CFYK-FM is a Canadian radio station, broadcasting at 98.9 FM in Yellowknife, Northwest Territories. The station broadcasts the programming of the CBC Radio One network and locally produced programs. CFYK was licensed in 1948 after an application by the Department of National Defence on behalf of the Royal Canadian Corps of Signals. It began operating in 1951 as a community radio station and was managed by civilian committee. It was turned over to the CBC in 1958. Local programming CFYK produces all of CBC Radio's local programs in the Northwest Territories, including ''The Trailbreaker'' on weekday mornings, the noon-hour program ''Northwind'', ''Trail's End'' in the afternoon, and ''Northern Air'' on weekend mornings. The station's afternoon programming also differs significantly from the rest of the network. Afternoon programming such as '' Q'' is pre-empted; instead, the stati ...

2,2,4,4-Tetramethyl-1,3-cyclobutanediol
2,2,4,4-Tetramethyl-1,3-cyclobutanediol (CBDO) is an aliphatic diol. This diol is produced as a mixture of ''cis''- and ''trans''-isomers, depending on the relative stereochemistry of the hydroxyl groups. It is used as a monomer for the synthesis of polymeric materials. CBDO is currently being researched as an alternative to bisphenol A (BPA). BPA is a precursor used in the production of a wide range of polymers including polycarbonates, polyesters, polysulfones, and polyester ketones. Replacement for BPA The controversies associated with BPA in large quantities are ultimately related to its endocrine disrupting abilities. Like BPA, CBDO is a diol with a structure suitable for making polyesters. CBDO’s C4 ring is sufficiently rigid to prevent the two OH groups from forming cyclic structures. Unlike BPA, there is no current evidence of carcinogenic or toxic effects from CBDO-based consumer products. There are, however, few studies on the toxicology of CBDO for both long ter ...
