Decrement time

SIGN is used to determine whether the carriage position is incrementing or decremented. TIME is the sampling time of the proportional control algorithm. 

It is important to realize that the CSHT does not predict the time to patient awakening but simply the time until the plasma concentration of a drug has fallen by half. The patient may need the plasma concentration to fall by 75% in order to awaken, and the time taken for this or any other percentage fall to occur is known as a decrement time. 

The CSHT is, therefore, a form of decrement time when the specified percentage is 50%. When using propofol infusions, the decrement time is commonly quoted as the time taken to reach a plasma level of 1.2 pg.ml-1, as this is the level at which wake up is thought likely to occur in the absence of any other sedative agents. 

Decrements in vigilance (i.e., ability to detect small changes in one s environment that occur at unpredictable times) decreased exercise performance in both healthy persons and those with chronic obstructive pulmonary disease... 

Sato et al. " measured the viscosities of some binary and ternary alkali carbonates. Since melt creep must be prevented, a highly sintered alumina crucible was used instead of a gold-plated nickel crucible. Homogeneity of a mixture sample was achieved by gas bubbling. A laser beam is combined with a computer-assisted time counter to obtain the logarithmic decrement. Roscoe s equationi3i has been used for calculation of the viscosity, while it has been claimed by Abe et al. that the viscosities calculated from Roscoe s equation are 0.6-1.5% lower than those from more rigorous equations. 

The first role of a reservoir is to impose on the system a gradient that makes the subsystem structure nonzero. The adiabatic flux that consequently develops continually decreases this structure, but the second role of the reservoir is to cancel this decrement by exchange of variables conjugate to the gradient. This does not affect the adiabatic dynamics. Hence provided that the flux is maximal in the above sense, then this procedure ensures that both the structure and the dynamics of the subsystem are steady and unchanging in time. (See also the discussion of Fig. 9.) A corollary of this is that the first entropy of the reservoirs increases at the greatest possible rate for any unconstrained flux. 

Both THC and ethanol increase reaction time, and produce decrements in standing steadiness and psychomotor coordination (Belgrave et al. 1979). Whereas the peak effects of ethanol appeared quickly and wore off quickly (after 280 minutes), THC s effects were slower in onset and longer in duration. The effects of combined THC and ethanol are additive and not synergistic, and THC did not alter blood-ethanol levels. Other studies have shown an interaction between ethanol and THC on psychomotor skills necessaiy for driving, although there were no interactions on the subjective "high," heart rate acceleration, or THC plasma concentration (Perez-Reyes et al. 1988). 

Evaporite and seasalt cycling effects are not included in this estimate. This was done by subtracting out molar concentrations equivabnt to that of the chloride ion. Increment seawater concentration is rbing over time decrement seawater concentration is declining over time. 

At the ID50, 302196 produces impairment of Variable Interval Time Reproduction (VITA) scores (Fig. 53). This decrement is very similar to that shown for Number Facility (Fig. 54). Four dose groups are shown in each graph. The decline in scores is very rapid and recovery occurs early. 

Acute exposure to levels of 200,000ppm and above causes deterioration of performance on tests of reaction time it has been suggested that the threshold at which nitrous oxide starts to affect performance lies between 80,000 and 120,000ppm. Other smdies have examined the effects of trace levels of nitrous oxide on performance tests, with conflicting results. In one unconfirmed study, volunteers exposed to 50 ppm for up to 4 hours showed decrements in audiovisual performance tests. In another report, similar exposures did not produce any changes in a battery of psychomotor tests including an audiovisual task, but there was a nonsignificant trend for mood factors such as tiredness to occur. ... 

Usual dose Initial dose of 25 mg twice/day, with increases in increments of 25 to 50 mg 2 or 3 times/day on the second and third day, as tolerated, to a target dose range of 300 to 400 mg/day by the fourth day, given 2 or 3 times/day. Further dosage adjustments should occur at intervals of at least 2 days. Dose increments/decrements of 25 to 50 mg twice/day are recommended. Efficacy was demonstrated in a dose range of 150 to 750 mg/day. The safety of doses above 800 mg/day has not been evaluated. 

Metabolic acidosis Hyperchloremic, nonanion gap, metabolic acidosis is associated with topiramate treatment. This metabolic acidosis is caused by renal bicarbonate loss because of the inhibitory effect of topiramate on carbonic anhydrase. Generally, topiramate-induced metabolic acidosis occurs early in treatment, although cases can occur at any time during treatment. Bicarbonate decrements usually are mild to moderate rarely, patients can experience severe decrements to values below 10 mEq/L. Conditions or therapies that predispose to acidosis may be additive to the bicarbonate lowering effects of topiramate. If metabolic acidosis develops and persists, consider reducing the dose or discontinuing topiramate.

As a second set of internal displacement coordinates we may choose the increments or decrements to the three OCO angles. Before using this set to form a representation which will tell us the normal coordinates involving inplane OCO bends, we must be careful to note that all of the coordinates in the set are not independent. If all three of the angles were to increase by the same amount at the same time, the motion would have A symmetry. It is obviously impossible, however, for all three angles simultaneously to expand within the plane. Thus the A representation which we shall find when we have reduced the representation is to be discarded as spurious. 

In view of the strong dependence of the mass transfer coefficient on moisture content and the 35-fold range of that property, the required residence time and other conditions will be found by analyzing the performance over small decrements of the moisture content.
