To simplify the calculation, the cornea is assumed to be a thin spherical lens with a fixed anterior to posterior corneal curvature ratio and an index of refraction of 1.3375. Central corneal power can be measured by keratometry or corneal topography. Corneal radius of curvature relates to corneal power with the equation: r = 337.5/K. [3]
The THM400 was the first three-speed, Simpson-geared automatic to use overrunning clutches for both first and second gear reaction, a feature that eliminated the need to coordinate the simultaneous release of a band and application of a clutch to make the 2-3 gear change. Owing to this feature, as well as the use of a large, multi-plate clutch ...

USAF officials fear that retiring the U-2 amid RQ-4 upgrades will create a capability gap [154] In the House Armed Services Committee's markup of the FY 2015 budget, language was included prohibiting the use of funds to retire or store the U-2; it also requested a report outlining the transition capabilities from the U-2 to the RQ-4 Block 30 in ...
In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. [1] In 1878, a hydroelectric power station was designed and built by William, Lord Armstrong at Cragside, England. It used water from lakes on his estate to power Siemens dynamos. The electricity supplied power ...
