Reduced frequency interval

Both extended spectra are now optimized by trial and error corrections of H(t) in such a way that, over the entire reduced frequency interval, G"(w) calculated by means of [6] approximates G (w) measured, and G (w) measured minus G (constant value. Of course, Equations [5] and [6] are now used with the extended integration limits. With some routine, this procedure yields two optimized spectra after about eight iterative adjustments of the entire extended spectra. [Pg.525]

Oligomenorrhea Reduced frequency of menses with a time interval between periods more than 40 days but less than 6 months. [Pg.1572]

Comprehensive investigations of these substances have long ago proven beyond doubt that psilocybin, mescaline and LSD are not physically addictive, nor do they cause withdrawal S5Tnptoms of any kind. Repeated self-experimentation over long periods of time is rare most long-term users eventually reduce frequency of use due to the nature of these substances that initiate powerful transpersonal processes and facilitate the emergence of personal conflicts. Besides, habitual daily users quickly develop tolerance to the point of being unable to experience any psychoactive effects at all. That is why clinical trials are spaced to allow for intervals of at least one week between repeated applications. [Pg.105]

To overcome difficulties associated with recording the very broad lineshapes encountered in " N NMR spectroscopy, a stepped-frequency approach can be used, in which the lineshape is constructed from observations made at a number of smaller frequency intervals. Figure 8.8A shows the lineshape determined in this manner for KNO3, together with the simulated lineshape (Hill and Yesinowski 1996). This approach is, however, very time consuming and inefficient, since only a small fraction of the spins is excited at any particular instant. To increase the sensitivity and reduce the recycle time, a technique known as Reorientation-Induced Redistribution of Isochromats (RotlsseRIe) has been developed, in which the powder sample is slowly rotated at 1 rpm about an axis perpendicular to the magnetic field (Yesinowski and... [Pg.475]

The advantage of this derivative spectroscopy [2] with a frequency-modulated laser is the possibility for phase-sensitive detection, which restricts the frequency response of the detection system to a narrow frequency interval centered at the modulation frequency Q. Frequency-independent background absorption from cell windows and background noise from fluctuations of the laser intensity or of the density of absorbing molecules are essentially reduced. Regarding the signal-to-noise ra-... [Pg.11]

In practice, since x(t) is a frequency band-limited signal, equation (11) shows that H(u) is known only on the finite interval wherein X(u) 0. There are also problems when the input signal is small, reduced to noise. [Pg.746]

Six placebo-controlled studies showed that duloxetine reduces incontinent episode frequency and the number of daily micturitions, increases micturition interval, and improves quality-of-life scores. These benefits were statistically significant but clinically modest. [Pg.961]

The therapy of a chronic disease requires repeated drug dosing. In the case of a short biological half-life, the drug has to be administered up to several times daily within short intervals. To reduce the application frequency, sustained formulations have been developed. For this purpose liquid crystalline excipients are appropriate candidates, because in a liquid crystalline vehicle the drug diffusion is reduced by a factor of 10 to 1000 in comparison with a liquid vehicle such as a solution [35-37]. The factor depends on liquid crystal. [Pg.143]
