The SD Series is a direct evolution of the Smith & Wesson SW designs. The grip angle is the same since the SD pistols use the same magazines as the Sigma pistols (though with different magazine bottom plates). The trigger guard is larger, and the SD line has industry-standard accessory rails rather than a proprietary rail.
In 2000 the SD card was announced. SD was envisioned as a single memory card format for several kinds of electronic devices, that could also function as an expansion slot for adding new capabilities for a device. [21] In 2001, SmartMedia alone captured 50% of the digital camera market and CF had captured the professional digital camera market.
Toshiba hoped the SD card's DRM would encourage music suppliers concerned about piracy to use SD cards. [9] The trademarked SD logo was originally developed for the Super Density Disc, which was the unsuccessful Toshiba entry in the DVD format war. For this reason, the letter "D" is styled to resemble an optical disc. [10]
By decreasing the wavelength, increasing the numerical aperture from 0.60 to 0.85, and making the cover layer thinner to avoid unwanted optical effects, designers can cause the laser beam to focus on a smaller spot, which effectively allows more information to be stored in the same area. [119] For a Blu-ray Disc, the spot size is 580 nm. [120]
Erythromelalgia, or Mitchell's disease (after Silas Weir Mitchell), is a rare vascular peripheral pain disorder in which blood vessels, usually in the lower extremities or hands, are episodically blocked (frequently on and off daily), then become hyperemic and inflamed.

[6] [9] Concentrations of LSD decreased following first-order kinetics with a half-life of 3.6±0.9 hours and a terminal half-life of 8.9±5.9 hours. [ 6 ] [ 9 ] The effects of the dose of LSD given lasted for up to 12 hours and were closely correlated with the concentrations of LSD present in circulation over time, with no acute tolerance ...
