Figure 4.5 Influence of oxidant stress on action potentials recorded In an isolated rabbit ventricular myocyte, (a) Control action potential, (b) Action potential recorded 3 min after exposure to oxidant stress induced by the photoactivation of rose bengal (50 nu). (c) Spontaneous and repetitive action potential discharges induced 6.5 min after exposure to rose bengal. Action potentials were recorded via a 2.5 MQ suction electrode and a current-clamp amplifier. The cell was stimulated at 0.1 Hz with a 2 ms suprathreshold current pulse and, when the cell showed automaticity (after 6 min), stimulation was stopped. Redrawn from Matsuura and Shattock (1991b).

Figure 6.7 depicts an autosampler employed in a jtPLC system. Figure 6.8 details the autosampler component. Samples are transferred from the desired well in the microtiter plate into the columns of the Brio cartridge. If a 384-well plate is employed, the autosampler will carry out 3 sets of 8 injections into the columns, for a total of 24 columns. The solvent (mobile phase) does not circulate in the cartridge but is diverted into a backpressure regulator located in the waste line (Figure 6.2). This process of injection is known as stop-flow injection. After all samples are placed into the injection pits of the 24 columns in the cartridge (Figure 6.5), a clamp containing a seal...

A solution of 3 ml (14 mmol) of freshly distilled sebacoyl dichloride (for preparation see above) in 100 ml of carbon tetrachloride is placed in a 250 ml beaker. A solution of 4.4 g (38 mmol) of hexamethylenediamine in 50 ml of water is carefully run on to the top of this solution, using a pipette. (The aqueous solution can be made more readily visible by coloring it with a few drops of phenolphthalein solution.) A polyamide film is immediately formed at the interface and can be pulled out from the center with tweezers or clamps and laid over some glass rods it can now be pulled out continuously in the form of a hollow thread and wound up on to a spool driven by a slow-running motor. The polycondensation comes rapidly to a standstill if the motor is stopped, but immediately recommences, even after some hours, when the motor is restarted.

Hose Clamp A mechanical device for compressing fire hose to stop die flow of water. 

Assemble an apparatus for distillation with steam (Fig. 59a). Transfer the aqueous solution of iodine into flask 4. Distil off the iodine. For this purpose, open the clamp on tee-piece 3 and heat the water in steam boiler 1 until it boils. Next regulate the rate of steam flow with the aid of the clamp and carefully heat flask 4. After the main part of the iodine gathers in glass tube 5, open the clamp and stop heating steam boiler 1 and flask 4. 

Cognate preparation. m-Nitrobenzyl alcohol. Clamp a 500-ml three-necked flask, equipped with a mechanical stirrer, a thermometer and a burette, above the bench so that an ice bath can be placed beneath it. Place a solution of 15.1 g (0.1 mol) of m-nitrobenzaldehyde (Expt 6.19) in 100 ml of methanol in the flask and, while stirring, add a solution of sodium borohydride (1.4g, 0.037 mol NaBH4 in 2 ml of 2 m sodium hydroxide diluted with 18 ml of water) at the rate of 0.5 ml per minute, with occasional cooling to keep the reaction at 18-25 °C. When about three-quarters of the solution has been added, there is no further tendency for the temperature to rise, and the addition is stopped. Treat a small portion of the reaction mixture with dilute sulphuric acid hydrogen should be evolved. 

If, in order to do maintenance on the meter, the process flow cannot be stopped and the measurement point cannot be bypassed, the selection choice is limited to clamp-on meters. If the available straight upstream pipe run is insufficient, consider using meters that require less (such as magnetic, which requires five) diameters. Even if the meter installation requirements can be met, their effect on the overall system cost must still be quantified because the cost should also include installation, operation, and maintenance expenses. 

More crude methods have to be used when patients are to be clamped at a level much below their fasting glucose. The most used is simply to infuse insulin, until the wanted level is reached. The discussion is then whether the infusion has to be stopped when the test insulin is given, or has to be continued in order to give comparable results [131, 132]. From Eq. (40) it follows that, of a resting HGO of 2 mg kg-1 min-1, some 1.14 mg kg-1 min-1 goes to the brain, and with G = 5 mM, the value of Vglut is 1-72 mg kg-1 min-1. 

Patching may be feasible for stopping leaks in vessels or storage containers, or in situations when the contents cannot be transferred. The usual patching method is to affix some type of mechanical device in, over, or around the leak to restrict flow. A variety of clamps, capping tools, and sleeves are commercially available for this purpose. For piping systems, one technique... 

In todays world, many U.S. chemical plants rely on specialty leak repair contractors to stop steam and other utility fluid nuisance leaks. However, in the mid-1970s these contractors were not immediately available to many plant sites, so the plants had to create their own clamps or other containment systems if shutdowns were to be avoided.
