In the previous sub-Section the theory-in-action, defined by Argyris (Argyris et al., 1996), sets the targets according to which a deviation is resolved. In his control paradigm De Leeuw (Leeuw de, 1986) calls this theory-in-action the controlling process, and he displays the task or transformation process as the controlled process, as can be seen in Figure 21. [Pg.69]

Crystallization and reactivity in two-dimensional (2D) and 3D crystals provide a simple route for mirror-symmetry breaking. Of particular importance are the processes of the self assembly of non-chiral molecules or a racemate that undergo fast racemization prior to crystallization, into a single crystal or small number of enantiomorphous crystals of the same handedness. Such spontaneous asymmetric transformation processes are particularly efficient in systems where the nucleation of the crystals is a slow event in comparison to the sequential step of crystal growth (Havinga, 1954 Penzien and Schmidt, 1969 Kirstein et al, 2000 Ribo et al 2001 Lauceri et al, 2002 De Feyter et al, 2001). The chiral crystals of quartz, which are composed from non-chiral Si02 molecules is an exemplary system that displays such phenomenon. [Pg.54]

Laparoscopy The liver is enlarged and displays a dark reddish cyanotic surface with a rounded margin. Congested veins and collaterals in the abdominal region suggest portal hypertension. Transformational processes may occur in a chronic course (in 30-40% of cases) or when the liver is only partially affected, so that even the picture of a cirrhosis has been observed. Ascites, occasionally also in its sanguinolent form, is detected in most patients. [Pg.830]

The anatase phase, for a long time considered as the most electrochemically active polymorph, [ZAC 88, ZHE 09] has a discharge potential around 1.8 V versus Li and displays a complex insertion mechanism in three stages [WAG 07] an initial Li insertion process according to a solid solution mechanism, then a biphasic transformation process from the initial phase to a phase crystallizing in an orthorhombic space group which corresponds to a distortion in the Ti s octahedral coordination sphere and finally a solid solution-type insertion reaction. This... [Pg.28]

Thermal treatment of shock-modified theta-phase alumina, which initially contained about 30% alpha phase, showed a dramatic change in the rate of transformation to the alpha phase [90B01]. As shown in Fig. 7.13, the shocked sample showed no evidence for an incubation period and displayed a rapid conversion to the alpha phase, in sharp contrast to the unshocked sample. Such behavior clearly indicates that the shock process resulted in formation of larger concentrations of alpha-phase nuclei. [Pg.178]

Chapter 8 consists of the following in Sect. 8.2 the physical model of the process is described. The governing equations and conditions of the interface surface are considered in Sects. 8.3 and 8.4. In Sect. 8.5 we present the equations transformations. In Sect. 8.6 we display equations for the average parameters. The quasi-one-dimensional model is described in Sect. 8.7. Parameter distribution in characteristic zones of the heated capillary is considered in Sect. 8.8. The results of a parametrical study on flow in a heated capillary are presented in Sect. 8.9. [Pg.351]

Transition metal centered bond activation reactions for obvious reasons require metal complexes ML, with an electron count below 18 ("electronic unsaturation") and with at least one open coordination site. Reactive 16-electron intermediates are often formed in situ by some form of (thermal, photochemical, electrochemical, etc.) ligand dissociation process, allowing a potential substrate to enter the coordination sphere and to become subject to a metal mediated transformation. The term "bond activation" as often here simply refers to an oxidative addition of a C-X bond to the metal atom as displayed for I and 2 in Scheme 1. [Pg.232]

Fig. 10.12. Pulse sequence for amplitude modulated 2D J-resolved spectroscopy. The experiment is effectively a spin echo, with the 13C signal amplitude modulated by the heteronuclear coupling constant(s) during the second half of the evolution period when the decoupler is gated off. Fourier transformation of the 2D-data matrix displays 13C chemical shift information along the F2 axis of the processed data and heteronuclear coupling constant information, scaled by J/2, in the F1 dimension.
