Holding current

Once fired, a thyristor cannot be controlled. Ft requires a forced commutation to switch it off and (he gate control is quite cumbersome. To swdtch OFT-, (he conducting current Is reduced to less than its holding current. The commutation circuitry is ihcrctbre highly complex an[Pg.118]

In this paper, we propose a dynamic SDR scheme to reduce both the key storage cost and the rekey communication cost of static SDR. Dynamic SDR uses a key tree that is large enough to hold currently active members (as opposed to all members, both active and inactive) in order to reduce key storage. This...

Auxiliary methods can hold current value when the auxiliary is inexpensive, available in both enantiomeric forms, and, for amine synthesis, can be incorporated with concomitant generation of the new stereogenic a chiral amine center. Reductive amination with chiral ammonia equivalents not only holds this potential but is now a proven and established method that allows chiral primary amine synthesis in two reaction steps (reductive amination and hydrogenolysis) from prochiral ketones. The approach is of interest because of its overall reaction step efficiency. 

As nientioned above, observations of PDRs reveal inhomogeneities down to the smallest accessible scales. For a fixed point in space, the oKserved spatial fluctuations lead due to hydrodynamic motions to temporal fluctuations ill the radiation field. If the time scale for the x ariation of the radiation field becomes comparable or even smaller than the timescale for the chemical reactions, the assumption of a kinetic equilibrium does not hold. Currently, we perform time dependent calculations for a chemical network consisting of 38 different species in order to study the influence of small scale fluctuations in the UV radiation field.

To understand the behavior of these processes, we associate one or more subscripted abstract variables to each declared object x in the HDL text, to hold current(x), the value of X when the description has stabilized (just before the clock edge), and the successively assigned values to the object in the process or always statement. 

Case (c). The switching device has no stable operating point between the high resistance OFF state and the conductive ON state to which the device switches when the voltage exceeds the threshold voltage V. The device switches to its original OFF state when the current is decreased below the holding current Ij. The characteristic is essentially symmetric. The threshold switch described by Ovshinsky (1967, 1968) is an example of this device. 

Each member of the rescue team shall be trained in basic first aid and in cardiopulmonary resuscitation (CPR). At least one member of the rescue team holding current certification in first aid and in CPR shall be available. 

The employer must also do these same things when setting up an in-house rescue team. But with an in-house team, the employer is responsible for providing all the equipment and PPE (and training the workers on how to use it). Training would have to include information on how to be an entrant and how to do the rescues. The rescue team employees would need training in basic first aid and CPR (at least one team member on active rescue duty must hold current certification in first aid and CPR). In addition, employees on a rescue team must practice making rescues at least once every 12 months. 

Deutsches Museum http //www.deutsches-museum.de/ (accessed September 21, 2010). The archives of the Deutsches Museum are the leading collections for the history of science and technology in Enrope. They hold currently 4.3 kilometers of archival material, sources, and documents. The archival collections focus on transportation, aeronautics, and astro-nantics, the history of physics and chemistry. The library offers literature that primarily relates to the history of the natural sciences and technology, ranging from nonfiction titles to scientific mannals or specialist essays and papers from the invention of the letterpress to the present day (from Web page).
