On wing times can reach 14,000 hours, an overhaul costs over $1.5 million and a set of LLPs $2.1 million for a 25,000 cycle life. [4] In 1995, GE invested $200 million to develop the -8C derivative for the CRJ700 .
The design was initiated by the U.S. EPA and the Lighting Research Center in 2004, in order to facilitate the deployment of compact fluorescent light bulbs with replaceable ballasts. [ 1 ] The GU24 fitting is compliant with a 2008 ruling by the California Energy Commission under Title 24 ( California Building Standards Code ) to require high ...
Often referred to as the Dash light series, it is part of the GE Dash 8 Series of freight locomotives. This locomotive model is distinguished from the predecessor Dash 8-40C by the addition of a newer "wide" or "safety" cab. A cowl-bodied version of this locomotive, built only for the Canadian market, was the GE Dash 8-40CM.
[5] Believed to be the first coupon ever, this ticket for a free glass of Coca-Cola was first distributed in 1888 to help promote the drink. By 1913, the company had redeemed 8.5 million tickets. [6] Coca-Cola's 1888-issued "free glass of" is the earliest documented coupon. [6] [7] Coupons were mailed to potential customers and placed in ...
While the purchase price of a CFL is typically 3–10 times greater than that of an equivalent incandescent lamp, a CFL lasts 8–15 times longer and uses two-thirds to three-quarters less energy. A US article stated "A household that invested $90 in changing 30 fixtures to CFLs would save $440 to $1,500 over the five-year life of the bulbs ...

[5] Recurring operating income rose by 34% to €1.2 billion , but was reduced by €107 million ( US$118 million ) due to the negative margins and initial costs of ...
In mathematics, the convergence condition by Courant–Friedrichs–Lewy (CFL) is a necessary condition for convergence while solving certain partial differential equations (usually hyperbolic PDEs) numerically. It arises in the numerical analysis of explicit time integration schemes, when these are used for the numerical solution.
Like the European modular furniture, display cabinets, ceiling tile grids, etc. they were designed for, these are based on multiples of the 300 mm (11.8 in) "metric foot" instead of the 12 in (305 mm) imperial foot, but are all 37 mm (1.5 in) shorter to allow space for the lampholder connections within the 300 mm modular units, and for much ...
