C, All ligands are part of a continuous local segment of the protein chain S (semicontinuous), the majority of ligands are from a continuous segment of the protein chain D (discontinuous), several separated segments. [Pg.85]

An additional five Ca " -binding sites listed in Table II have continuous local peptide segments, providing the majority of the Ga ligands from protein [Table II 2SEC site I, four of seven ligands (Fig. 2f) ITEC site... [Pg.108]

Structurally, the Shilbottle Coalfield is relatively simple. The strata strike approximately 45°N and dip about 10° to the SE. Antithetic extensional faults disturb seam continuity locally (Fig. 6), and a single major fault system striking approximately 85°N (cropping out in the vicinity of Whittle Fig. 6) down-throws the coal to the north by some 200 m. [Pg.196]

The most favorable conditions for reactive processing of monolithic articles are created when the frontal reaction occurs at a plane thermal front. For example, a frontal process can be used for methyl methacrylate polymerization at high pressure (up to 500 MPa) in the presence of free-radical initiators. The reaction is initiated by an initial or continuous local increase in temperature of the reactive mass in a stationary mold, or in a reactor if the monomer is moving through a reactor. The main method of controlling the reaction rate and maintaining stability is by varying the temperature of the reactive mass.252... [Pg.174]

Stress corrosion cracking is a form of localized corrosion, where the simultaneous presence of tensile stresses and a specific corrosive environment prodnces metal cracks [157, 168]. Stress corrosion cracking generally occnrs only in alloys (e.g., Cn-Zn, Cu-Al, Cu-Si, austenitic stainless steels, titaninm alloys, and zirconinm alloys) and only when the alloy is exposed to a specific environment (e.g., brass in ammonia or a titaninm alloy in chloride solutions). Removal of either the stress on the metal (which must have a surface tensile component) or the corrosive environment will prevent crack initiation or cause the arrest of cracks that have already propagated. Stress corrosion cracking often occurs where the protective passive film breaks down. The continual plastic deformation of the metal at the tip of the crack prevents repassivation of the metal surface and allows for continued localized metal corrosion. [Pg.1815]

Meanwhile the technology of continuous local heat volume formation has been improved to such an extent that systems of this kind are permitted under the applicable standardization regulations and ate in use. This method employs on-site heat volume calculators which continuously (i.e. at very small intervals) link the measured volumes with the upper calorific values applicable at the same time. [Pg.336]

The problem was addressed by adding the drugs into a polymer matrix that is coated on the stent. This provided continuous local drug release to the injured lesion. [Pg.412]

Each operation shall be provided with continuous local exhaust ventilation so that air movement is always from ordinary work areas to the operation. Exhaust air shall not be discharged to regulated areas, non-regulated areas, or the external environment unless decontaminated. Clean makeup air shall be introduced in sufficient volume to maintain the correct operation of the local exhaust system. [Pg.327]

Figure 3.7 Representative curves for acoustic emission signai versus ioad for diamond-iike carbon coatings on siiicon. The solid line (a) illustrates the case with no local adhesion failure. The short-dashed line (b) illustrates the case with limited local adhesion failure. The long-dashed line (c) illustrates the case with "continuous" local adhesion failure. The spectra are offset vertically for clarity. ... [Pg.58]

Continued localization of shear is expected to lead to fracture by the various plastic failure processes, although the exact mechanism by which shear localization causes fracture is not known (Birbaum, 1990 Mag-nin et al., 1990). Moreover, it was shown in Sec. 5.3 that a high hydrogen concentration can be reached near dislocation pile-ups, which can favor cracking. [Pg.255]

Definition 8.2. A system X [continuous or discrete) is said to have a modulus if in some subspace B of the space of dynamical systems, where X G B, a continuous, locally non-constant functional h is defined such that if X and X are topologically equivalent, then h[X) = h[X). [Pg.74]
