Adjustments with Each Experiment

It turns out that, in the case of an imperfect inverting pulse, the factor of 2 in equation (3) must be substituted by an unknown factor K (< 2) it is thus recommended to turn to a non-linear fit of M fx) = Mo[l—ifexp(—x/Tj)], where the three quantities Mq, K, and Ti have to be refined, starting for example from values deduced from (4). It must be stressed that the measurement, as described above, does not require the system to have returned to equilibrium between two experiments with different x values, or between two consecutive scans if accumulation is necessary for improving the S/N ratio (4). If the repetition time T is smaller than 5Ti, the factor K of the above equation depends on the ratio T/Ti here and, just as before, has to be adjusted for each resonance. [Pg.7]

Transferring patients not currently treated with entacapone tablets from carbidopa/levodopa to carbidopa, levodopa, and entacapone combination tablets In patients with Parkinson disease who experience the signs and symptoms of end-of-dose wearing-off on their current standard release carbidopa/levodopa treatment, clinical experience shows that patients with a history of moderate or severe dyskinesias or taking more than 600 mg/day of levodopa are likely to require a reduction in daily levodopa dose when entacapone is added to their treatment. Maintenance therapy Individualize therapy and adjust for each patient according to the desired therapeutic response. [Pg.1322]

Typical Experiment. Polyox resin, Grade WSR-5M5, was transferred to a stainless steel hopper positioned over a vibrating feeder. The belt speed was set at 90 inches per minute, and the accelerator was adjusted (with the shutter closed) to deliver a current of 250 /xa. at 2 m.e.v. The shutter was opened, and the feeder was activated. The calculated dose was 0.75 megarad. After irradiation, the viscosity of each sample was measured. The average 5% aqueous solution viscosity for 27 samples of one particular blend was 78 7 cp., and the average for 16 samples of another was 80 =b 5 cp. [Pg.126]

To complete each experiment, prepare the reaction mixture as described above. Mix well and transfer to the reaction tube. Insert a small magnetic stir bar and place the pH electrode into the reaction mixture. Turn on the magnetic stirrer to a slow rate and check to see whether the stirrer affects the pH meter. Adjust the pH of the reaction mixture to a pH reading in the range of 6 to 6.2 with acid or base. Turn on the pH meter and recorder, if available, and then turn on the lamp to illuminate the chloroplasts. Mark the recorder sheet at the time the lamp is turned on. Allow the recorder to trace the pH reading with time for 60 seconds, and then turn off the light but continue to record the pH. Turn the lamp on after a dark interval of 30 seconds. Continue to record the pH for 60 seconds, again turn the lamp off, and continuously record the pH. Repeat the experiment with a fresh portion of chloroplasts. [Pg.353]

A and were subsequently swollen with monomer to the extent of 150-175 parts of monomer per hundred parts of polymer. The surfactant level was adjusted to 45% of saturation on the swollen particle surface so that each experiment was equivalent in surface density of surfactant at the start of the reaction. That maintained a stable latex throughout the polymerization and avoided new particle formation. [Pg.332]

As an example, fraction P2 of the BA waste experiment corresponded to that volume (= 1 m3) of percolate recovered between the time when the L/S 1 ratio was reached and that when the L/S 2 was reached. Received in the laboratory after a maximum time of 48 h, percolate samples were immediately treated in a manner similar to leachates obtained in the prerequisite study (i.e., centrifugation during 10 min at 3500 rpm, pH and conductivity measurements of each supernatant). The ecotoxicity of the different fractions was then assessed without filtration and pH adjustment with the same battery of bioassays used for the prerequisite study. [Pg.367]

For each experiment, the supernatant was placed in 15-mL conical tubes, and the pH was adjusted with either 1 N KOH or 1N HN03. The pH of the supernatant after the bioreactor run was 7.0. Simulated potato effluent (SPE) medium was used as a surfactin-free control and the pH adjusted likewise. SPE contained the following per liter of nanopure water 5 g of potato starch, 3.5 g of peptone, 3.5 g of tryptone, 0.2 g of MgS04-7H20,0.1 g of yeast extract, and 0.8 g of (NH4)2S04. [Pg.828]

For each experiment, up to 10% (w/v) NaCl was placed in 15-mL conical tubes. The supernatant was added and the tubes were gently stirred on a laboratory rotator for 2 h. With concentrations above 3%, the supernatant became cloudy with a precipitate that interfered with surface tension measurements. The supernatant was therefore left overnight in an upright position to allow the precipitate to settle out, and readings of surface tension were taken the following day. The SPE medium was used as a surfactin-free control and NaCl added likewise. When pH was included as a parameter in this experiment, NaCl was added first and the supernatant was stirred for 2 h. Then the pH of the supernatant was adjusted with either 1 N KOH or 1 N HNOs. [Pg.829]

All d/p cells can be provided with zero, span, elevation, and depression adjustments, either mechanical or electronic. Table 3.114 shows some typical d/p cell ranges and the available elevation and suppression setting adjustments for each. Whenever the d/p is at an elevation other than the connecting nozzle on an atmospheric tank, the zero of the d/p cell needs to be elevated or depressed. It is important to realize that two zero-reference points exist. One is the level in the tank that is considered to be zero (lower-range value) when the tank is almost empty. The other zero-reference point is the point at which the d/p cell experiences a zero differential pressure (zero value of the... [Pg.452]

The optimisation of the bio-oil was aimed at adjusting the operating conditions of the fast pyrolysis process to maximize the concentration of these reactive groups in the bio-oil, while maintaining a high overall oil yield. Figure 1 shows the main part of the small-scale production facility for small amounts of the oil. It consists of the biomass feeder, the reactor and a bio-oil collection system. Before each experiment, a batch of sand was preheated inside an electrical furnace to about bOO°C, where after it is mixed with cold sawdust in the bottom of the cone. The produced vapours could be immediately removed from the hot reactor, and collected in several water-cooled vessels. [Pg.1589]
