Adjacent domain

Thus, in case of a strong binding with chemisorbed particle the surface of a solid body becomes charged with relative to its volume which inevitably leads to band bending in the surface-adjacent domain...

The theoretical models of effects of recharging of the surface on the band diagram in the surface-adjacent domain of semiconductor adsorbent accompanying adsorption have been developed. The effect of the surface band bending in semiconductor adsorbent on its electrophysical characteristics caused by transition phenomena have been studied. The theories of adsorption-caused response of above characteristics were derived for both ideal monocrystalline adsorbent [4] and monocrystal with... 

Numerical simulations indicate that relay of cAMP pulses represents a different mode of dynamic behavior, closely related to oscillations. Just before autonomous oscillations break out, cells in a stable steady state can amplify suprathreshold variations in extracellular cAMP in a pulsatory manner. Thus, relay and oscillations of cAMP are produced by a unique mechanism in adjacent domains in parameter space. The two types of dynamic behavior are analogous to the excitable or pacemaker behavior of nerve cells. 

However, the highly anisotropic conductivity within each domain also means that overall sample conductivity is sensitive to features of the macroscopic phase structure. Factors which promote particular arrangements of adjacent domains should influence conductivity. So should structural defects within a domain which would allow appreciable charge... 

These results show a clear distortion of substrate binding and catalytic activities upon fragmentation of the multienzymes. The substrate pocket architecture seems to depend on the context of adjacent domains as well. Although questions remain, the linearity rule of NRPS holds in ACV synthetases. Open questions remain on the fate of possibly misactivated amino acids in the terminal... 

Block copolymers consist of chemically distinct polymer chains that are tethered together to form a single macromolecule. If the individual blocks are immiscible when they are unattached, phase separation will also normally occur in the case of the copolymer, with morphologies that depend on the relative composition of the separate block species, and their manner of attachment (diblocks, triblocks, stars, etc.). This is a result of the physical connection of the blocks, which prevents them from separating over distances greater than the contour lengths of the respective blocks. The result is a microphase separation with adjacent domains that are richer in either of the chemical species. 

Figure 18 The structure of the extracellular region of Ep-cadherm (1L3W). Calcium ions bind to the loops between each two adjacent domains and the whole protein in the structure forms a curvature. N-acetyl-D-glucosamine molecules attached to the cadherin surface are in gray...

Fig. 3 Geometric models representing packing behavior of micelles, inverse micelles, and lamellar structures. Lipid molecules with domains that occupy a large lateral distance compared to adjacent domains of the molecule will conform to corresponding shapes and packing behavior. Micelles and inverse micelles approximate cone shape, whereas lamellar systems resemble cylinders. (Adapted from Refs. l)...

The change in the sign of the order parameter at the surface has been observed (for ferroelectricty) by using a model of imaging developed for the detection of static surface charge (Saurenbach and Terris 1990). For ferroelastics, this corresponds to the profile of the lateral reactive force. The SFM non-contract dynamic mode images (Lithi et al 1993) would correspond to the distribution of the normal reactive force. The divergence of the lateral force distribution away from the centre of the wall can be attributed to the simulated infinite extension of the lattice. In the simulated array, the lateral component of the force reached a finite value between two adjacent domain walls. 

Members of the PLD superfamily that exhibit PLD activity contain four conserved sequences (I—IV) of which sequences I and IV contain the HKD motifs [4] (Fig. 4.1). The functions of sequences I and III have not been defined, but it is assumed they participate in catalysis. Two adjacent domains, PX (Phox homology) and PH (pleckstrin homology), are located in the N-terminal sequences of mammalian, yeast and nematode PLDs and in the plant PLD C isozymes, but are absent from bacterial and most plant enzymes [5, 6]. The plant PLDs lacking the PX/PH tandem domain contain a Ca /phospholipid binding domain, designated C2, at the N-terminus and require Ca for activity [6]. 

Consider a molecule diffusing in free space or a solute molecule diffusing in solution. Upon colliding with a surface, assume that the molecule is sufficiently entrained by surface forces that there results a reduction in dimensionality of its diffusion space from d = 3 to d — 2, and that in its subsequent motion the molecule is sterically constrained to follow the pathways defined by the lattice structure of the surface (or, perhaps, the boundary lines separating adjacent domains). If at some point in its trajectory the molecule becomes permanently immobilized, either because of physical binding at a site or because an irreversible reaction has occurred at that site, then, qualitatively, this sequence of events is descriptive of many diffusion-reaction processes in biology, chemistry and physics.
