The relative configurations of vicinal protons follow from the characteristic values of their coupling constants. Thus 16.1 Hz confirms the trans relationship of the protons on C-8 and C-9, 10.8 Hz confirms the cis relationship of the protons on C-6 and C-1. The 2.0 Hz coupling is common to the oxirane protons at = 3.00 and i.27 this value fixes the trans relationship of the protons at C-4 and C-5 following a comparison with the corresponding coupling in the methyloxirane (2.6 Hz). The anti relationship of the protons A-H and h-H can be recognised from their 8.7 Hz coup-... [Pg.187]

Phenol and hexamethylphoshoramide (HMPA) were selected, respectively, as the standard H-bond donor and H-bond acceptor with their values fixed on free energy and enthalpy H-bond scales for phenol, -2.50 for the H-bond donor enthalpy factor (TJ and also for the H-bond donor free energy factor (Ca) for HMPA, 2.50 for the H-bond acceptor enthalpy factor ( J and 4.00 for the H-bond acceptor free energy factor (CJ. [Pg.132]

Resource value fixed production costs cfc, Vr e i in the resource-specific currency are input data not decision-relevant for optimization, but being used in order to calculate earnings before tax profits. Production fixed costs include the value depreciation of the resource, shift personnel costs and other fixed production-related cost blocks. [Pg.192]

Therefore, the growth rate, /i, for this bacterial culture, after an initial phase of very rapid exponential growth, will ultimately settle down to a value fixed by the rates of wash out plus die off ... [Pg.748]

In the following phase diagrams of panel b), c), d), e) we keep the value fixed (y i=70 meV), while we change the J2 and 73 values in order to show the effects of the strength of the anisotropic interactions on the thermodynamic behaviour of the system. [Pg.152]

Value fixed in the refinement due to the statistical disorder of the ligands in the cubic space group. [Pg.82]

With this value fixed, several interesting quantities depend only on the product kA and the rate of light absorption J. These quantities are... [Pg.10]

When a chemical system is studied, it is assuredly very important to determine its variance whose value fixes the form of the equilibrium law for the system but before even calculating the variance, it is expedient to answer this question Is the equilibrium of the system stable, indifferent, or unstable ... [Pg.473]

The first attempt at estimating interindividual pharmacokinetic variability without neglecting the difficulties (data imbalance, sparse data, subject-specific dosing history, etc.) associated with data from patients undergoing drug therapy was made by Sheiner et al. " using the Non-linear Mixed-effects Model Approach. The vector 9 of population characteristics is composed of all quantities of the first two moments of the distribution of the parameters the mean values (fixed effects), and the elements of the variance-covariance matrix that characterize random effects.f " " ... [Pg.2951]

With respect to equation (3.17), the standard normal distribution function has a mean value fix = 0 and a standard deviation cr = 1. The area under a standard normal distribution is equal to unity. The standard normal distribution function can be written as N(0,1). [Pg.40]

In practice, because of some instrumental or environmental errors, an isosbestic point is rather a small surface than a real point, and a procedure has been proposed for its detection [8,9]. An isosbestic point is defined by the wavelength XjP (orX/p for hidden IP) as a point where the apparent coefficient of variation (CV ) is lower than a limit value (fixed to 2.5%, value obtained from a statistical study on repeatability) ... [Pg.32]
