Domain longitudinal

The obtained oscillation wavelength values can be compared approximately with local order domain longitudinal length, which in model [8,9] is accepted to be equal... 

For the NFS spectrum of [Fe(tpa)(NCS)2] recorded at 108 K, which exhibits a HS to LS ratio of about 1 1, a coherent and an incoherent superposition of the forward scattered radiation from 50% LS and 50% HS isomers was compared, each characterized by its corresponding QB pattern (Fig. 9.16) [42]. The experimental spectrum correlates much better with a purely coherent superposition of LS and HS contributions. However, this observation does not yield the unequivocal conclusion that the superposition is purely coherent, because in the 0.5 mm thick sample the longitudinal coherence predominates since many HS and LS domains lie along the forward scattering pathway. In order to arrive at a more conclusive result, the NFS measurement ought to be performed with a smaller ratio aJD on a much thinner sample. Such an experiment would require a sample with 100% eiuiched Fe and a much higher beam intensity. 

Dynamic parameters for heterogeneous systems have been explored in the liquid, liquid like, solid like, and solid states, based on analyses of the longitudinal or transverse relaxation times, chemical exchange based on line-shape analysis and separated local field (SLF), time domain 1H NMR, etc., as summarized in Figure 3. It is therefore possible to utilize these most appropriate dynamic parameters, to explore the dynamic features of our concern, depending upon the systems we study. 

Of particular practical value for studies of fibers is /, (x3) (the intensity projected on the direction of the fiber axis, x3). It measures the average domain extensions and their arrangement in fiber direction. The information contained in this intensity describes the longitudinal structure after Bonart [16]. In order to demonstrate the chord distributions related to the longitudinal structure we may imagine that one of the directions indicated in Fig. 8.17 were the fiber axis. 

The first vector lists the relevant ecological domains of the river system the hydrological character the longitudinal, vertical and lateral connectivity aspects of sediment transport and morphology landscape features and biotopes as well as relevant aspects of aquatic ecosystems. 

Figure 12.5 Calculated mean temperature fields in combustors with a set of similar open-edge V-gutter flame holders of height H = 3 cm and apex angle of 60°. The isoterms divide the entire temperature interval from the initial temperature To to combustion temperature Tc into 10 uniform parts and correspond to t = 27.5 ms. The combustor is 1 m long and the distance between the planes of flame holders is 0.05 m. Flame holders are shifted in longitudinal direction by OH (no shift) (a), IH (6), 2H (c), 3H (d), and 5H (e). Combustion of stoichiometric methane-air mixture at the mean inlet velocity Ui = 20 m/s, po = 0.1 MPa, To = 293 K, ko = 0.24 J/kg, /o = 4 mm. The lower and upper boundaries of the computational domain are the symmetry planes...

Similarly to non-selective experiments, the first operation needed to perform experiments involving selective pulses is the transformation of longitudinal order (Zeeman polarization 1 ) into transverse magnetization or ly). This can be achieved by a selective excitation pulse. The first successful shaped pulse described in the literature is the Gaussian 90° pulse [1]. This analytical function has been chosen because its Fourier transform is also a Gaussian. In a first order approximation, the Fourier transform of a time-domain envelope can be considered to describe the frequency response of the shaped pulse. This amounts to say that the response of the spin system to a radio-frequency (rf) pulse is linear. An exact description of the... 

Fig. 6.10. Structure of Ca -cal-modulin. a) Structure of free Ca -calmodulin. Calmodulin is composed of two domains that can each bind two Ca ions. Both domains are linked via a flexible structural element. The Ca ions are represented as spheres. MOLSKRIPT representation according to Krauhs, (1991). b) Ca -calmodulin in complex with a peptide that is derived from the Ca -binding domain of the myosin light chain kinase. Ca -calmodulin is represented as a band, and the peptide substrate is a ball and stick" model. The perspective is along the longitudinal axis of the hnear peptide substrate.
