Triggered automaticity

Calculate the relative number of atoms of each element contained in each of the following alloys (a) Wood s metal, which is a low-melting-point alloy used to trigger automatic sprinkler systems and is 12.5% tin, 12.5% cadmium, and 24% lead by mass in bismuth (b) a steel that is 1.75% by mass carbon in iron. 

Two forms of abnormal activity, early (top) and delayed after depolarizations (bottom). In both cases, abnormal depolarizations arise during or after a normally evoked action potential. They are therefore often referred to as "triggered" automaticity that is, they require a normal action potential for their initiation. 

Instruments designed to detect and warn about leaks, acetone escapes and small fires before they become serious, and maybe even trigger automatic fire-fighting equipment, can also be installed. 

The application of AMDIS is triggered automatically by the end of the chromatographic run. It works in the background and the results of intermediate processes are not visible on the screen. The program detects peaks in the process of deconvolution, isolates their spectra from the background and overlapping peaks and compares the pure spectra of detected peaks with the spectra in the library currently used by AMDIS. 

Triggered automaticity is also a possible mechanism for abnormal impulse generation. Briefly, triggered automaticity refers to transient membrane depolarizations that occur during repolarization (early after-depolarizations [EADs]) or after repolarization (delayed afterdepolarizations [DADs]) but prior to phase 4 of the action potential. After-depolarizations may be related to abnormal calcium and sodium influx during or just after full cellular repolarization. Experimentally, early after-depolarizations may be precipitated by hypokalemia, type la antiarrhythmic drugs, or slow stimulation rates— any factor that blocks the ion channels (e.g., potassium) responsible... 

Daemon A long-lived computer process that runs unattended to perform continuous or periodic systemwide functions. Some daemons are triggered automatically to perform their tasks, while others operate periodically. 

The driver system does not have an automatic Safety Evaluation component like the carriers system does (once a month carriers are automatically evaluated based on their BASIC Scores), so there are no Intervention Thresholds that will trigger automatic interventions for drivers (at this time). This is what some have interpreted to mean that drivers are not being evaluated or intervened with. ... 

Failing to require a driver to make a record of duty status (requires a violation threshold of 51% or more of examined records to trigger automatic failure). 

Although fatal and poorly tolerated ventricular tachyarrhythmias are initiated and perpetuated by one of three fundamental mechanisms (reentry, triggered automaticity, and abnormal automaticity), clinically, they arise from a broad range of pathologic conditions that are difficult, if not impossible, to quantify. 

Following manual stimulation of active contraction in the apices of the top two cells to initiate the simulation, the apices of the neighbouring active cells are stretched and so triggered, automatically, to contract. This leads to a wave of contraction propagated, domino-like, from cell to cell. These coordinated changes in cell shape lead to an overall change in tissue form similar to that seen in neural tube formation (Fig. 2). 

In the first set of conditions contraction of sides was triggered automatically. All of the cells of the reticulum were active and so responded automatically to the stretching of some cell sides which occurs as the wound opens. The results of this simulation suggest that these conditions can not account for the wound closure seen in real embryonic tissues (Fig. 5). The wound starts to close but then re-opens because cells peripheral to the wound become stretched and they contract, pulling the wound open. 

Statistical process control (SPC) aligns data of measured samples with historical trends and control limits which are based on observed statistical data. Notifications to process engineers or immediate corrective actions are triggered automatically if an instable behavior of the controlled process is recognized (Dietrich and Schulze 2003). 

The system evaluations are revised to include a consideration of the thrust loads associated with system actuation. The thrust loads occur when the seismic triggers automatically actuate the injection system on a design basis earthquake (DBE). 

Safety features on the loop included burst disks for over-pressure protection on the gas side and pressure relief valves on the water side. An emergency shutdown could be commanded by the user, or triggered automatically in the event a safety device was activated. The emergency shutdown would command the turbines to shut down and turn off alt heater power. A safety barrier to provide noise reduction and to protect against debris (in the event of a catastrophic failure) was considered. The requirements for the barrier had not been finalized at the time the project was canceled. 

Manual initiation - All protective actions are normally triggered automatically but they can also be triggered manually on operator s request. Nevertheless, once a protective action is initiated, manual actions can not prevent or interrupt the normal execution of the required protective action.
