Preload is an engineering term with several meanings. In the general sense, it refers to the internal application of stress to certain mechanical systems. In the general sense, it refers to the internal application of stress to certain mechanical systems.
Multiple techniques exist for preload control to ensure that the tension in the bolt is close to the one specified in the design (some bolt-to-bolt statistical variations are inevitable): [1] torque-controlled tightening is a simple and most popular approach: the fastener is tightened until the torque limit is reached.
Preload can still be approximated by the inexpensive echocardiographic measurement end-diastolic volume or EDV. Preload increases with exercise (slightly), increasing blood volume (as in edema, excessive blood transfusion (overtransfusion), polycythemia) and neuroendocrine activity (sympathetic tone). An arteriovenous fistula can increase ...
Photo-activated localization microscopy (PALM or FPALM) [1] [2] and stochastic optical reconstruction microscopy (STORM) [3] are widefield (as opposed to point scanning techniques such as laser scanning confocal microscopy) fluorescence microscopy imaging methods that allow obtaining images with a resolution beyond the diffraction limit.
A complementary maneuver for differentiating disorders is the Valsalva maneuver, which decreases preload. [7] Handgripping maneuver Cardiac Finding
Preload may refer to: Science and technology. Preload (cardiology), maximum stretch of the heart at the end of diastole; preload (software), code-prefetching ...
Designed to be attractive to first-time users, the Palm Z22 included many of the basic applications made famous by the iconic Palm family of handheld PDAs. [2] Positioned as an entry-level PDA and priced below the $100 price mark it lacked pricy extras such as: a camera, an MP3 player, an expansion SD memory slot, etc.
