Extramammary Paget's disease (EMPD) is a rare and slow-growing cancer, which occurs within the epithelial tissues [1] and accounts for 6.5% of all Paget's disease. [2] This disease presents similarly to the more conventional form of mammary Paget's disease (MPD). [ 3 ]
EPDM rubber (ethylene propylene diene monomer rubber) [1] [2] [3] is a type of synthetic rubber that is used in many applications. EPDM is an M-Class rubber under ASTM standard D-1418; the M class comprises elastomers with a saturated polyethylene chain (the M deriving from the more correct term polymethylene).
The de facto standard 8 inch FDD interface is based upon the Shugart Associates models SA800/801 [3] FDDs and models SA850/851 [4] FDDs. [5]: 171 The signal interface uses a 50-pin PCB edge connector which mates to a flat ribbon cable connector. Separate connectors are provided for both AC and DC power, as many 8 inch drives used AC spindle motors.
1.8-inch drives with ZIF connectors were used in digital audio players, such as the iPod Classic, and subnotebooks. Later 1.8-inch drives were updated with a micro-SATA connector and up to 320GB of storage (Toshiba MK3233GSG). The 1.8-inch form factor was eventually phased out as SSDs became cheaper and more compact. [38]
The half-angle (between the taper surface and the axis of the pipe) is arctan(1 ⁄ 32) ≈ 1.7899° ≈ 1° 47′. The standard for Nominal Pipe Size (often abbreviated NPS, which should not be confused with the abbreviation NPS for the straight thread form standard) is loosely related to the inside diameter of Schedule 40 series of sizes.
There are actually two Excellon formats, the older Excellon 1 and Excellon 2. Excellon 2 is a superset of IPC-NC-349. Commands from both are sometimes confusingly mixed in the same file. Excellon Automation stopped publishing the specification of its format, without statement on the IP and usage rights of the format. An archived copy exists. [8]
If hard covers are desired, they must be punched as well. In bulk applications, a paper drilling machine may be used. Then the user chooses a spine size that will match the document. Standard sizes are 4.8 mm (3 ⁄ 16 in) (for 16 sheets of 20# paper) up to 51 mm (2 in) (for 425 sheets). Spine lengths are generally 280 mm (11 in) to match the ...
The precise origins of the dimensions of US letter-size paper (8.5 × 11 in) are not known. The American Forest & Paper Association says that the standard US dimensions have their origin in the days of manual papermaking, the 11-inch length of the standard paper being about a quarter of "the average maximum stretch of an experienced vatman's arms".
