Sheet overlay

FIGURE 2 Panel A shows the secondary structural Greek Key motif of CC chemokines, as typified by CCL2. Three antiparallel p-pleated sheets overlay a C-terminal, a-helical domain. Panel B shows the elongated CCL2 dimer, which is facilitated by interactions of the chemokine N-termini. The CCL2 monomers making up the dimer are depicted in blue and red. 

Epoxy resins are also used in special appHcations, such as an overlaying procedure requiring a durable, heat-resistant bond of a difficult-to-bond overlay on a wood-base panel substrate. Metal sheets used as overlays, for example, often require an epoxy adhesive. 

Ferrous-aUoy-clad tube sheets are generally prepared by a weld overlay process in which the alloy material is deposited by welding upon the face of the tube sheet. Precautions are required to produce a weld deposit free of defects, since these may permit the process fluid to attack the base metal below the alloy. Copper-aUoy-clad tube sheets are prepared by brazing the alloy to the carbon steel backing material. 

Computational accuracy can be dramatically improved by dynamically adding elements where they minimize the error. For example, more elements ean be added in the neighborhood of a strong gradient in the velocity to help resolve shocks and vortex sheets. Elements may be removed from regions of smooth flow to minimize the computational cost without degrading the overall accuracy. The concept is shown in Fig. 9.6 where a finer mesh overlays the original mesh. This mesh refinement can be carried out to as many levels as necessary [15], [16], [17]. 

Hot melts are sometimes applied on top of a water-based primer, as mentioned above. The primer penetrates the paper and stiffens the ends of the paper sheets prior to their being attaehed to the eover with a hot melt overlayer. In some eases a pre-primer is employed whieh aetually penetrates eaeh sheet and stiffens the eore of the paper as well. 

MCBase offers the possibility to load the original CAMPUS data of different suppliers from version 3.0 and higher into one database, which allows direct comparison. It has been developed in close cooperation with the CAMPUS consortium. For more information see http //www.m-base.de/. MCBase is user friendly and offers extremely efficient handling of material data. All CAMPUS options are available define search profiles define and sort tables print tables and data sheets curve overlay scatter plots. In addition MCBase 4.1 offers search in curves search for comparable grades text search update via Internet calculation of simulation parameters. A French version of MCBase is available from the distribution agent in France. 

Figure 10 The global structures of Bowman-Birk inhibitors are diverse, but the reactive sites are structurally highly conserved. Reactive sites are oriented to the bottom right corner. The double-stranded /3-sheets neighboring the reactive sites are clearly visible, (a) 1 mvz, (b) 1 bbi, and (c) 1 h34. (d) The overlay of the backbone traces of the three BBIs ((a)-(c), colors as before) reveals their structural similarity. Additionally SFTI-1 (green, Ijbl) adopts the same fold in its active site. The residues (Arg in 1 mvz, Lys for other peptides) are also shown N and C denote the N- and C-termini of the truncated loops.

Vinyl overlays are thin sheets of polyvinyl chloride, often with a simulated grain pattern, which are glued to the particleboard to obtain an inexpensive finish of relatively low durability. Particleboard panels containing a 3"dimensional design can be vacuum laminated with vinyl films, provided sharp corners are not present in the design. The thermoplastic vinyl film is heated to the softening temperature and, as the air is withdrawn from between the film and the machined panel, atmospheric pressure from above forces the film to conform to the contours of the panel. 

Advantages of plywood are many fold. The chief purpose in overlaying the wood first practiced by the ancients and later by artisans in the 18th and 19th centuries was to produce a surface of beauty over a less aesthetic surface. Today plywood is a mixture of this same objective of aesthetics and the functional period. The inherent property of veneercutting utilizes the valued woods in full-size sheets to its greatest potential, whereas other methods of utilization would be too costly or impossible.

Pru av 1 represents an overlay of 22 chains retrieved from RCSB Protein Data Bank (accession number le09), Api g 1 (2bk0). Highly flexible loops between (33-(34 and (37-a3 structures are depicted in blue, (3-sheets in green, and a-helices in red. 

A recent variant of laminates of this nature is surfaced with two or more transparent overlay sheets, each of which carries a printed pattern that forms part of the whole design the result is to give depth to the design, and a three-dimensional effect. 

In laminates intended for use out-of-doors papers with superior colourfastness may be used and normally their construction includes an overlay sheet of ultra-violet absorbing thermoplastic film—which helps to reduce fading of the colour, and whitening. 

General Survey. The general survey is conducted for one USGS quadrangle sheet at a time. Historic aerial photographs are interpreted for selected years (generally ten year intervals) to identify abandoned dumps. A record of interpretations is made on mylar sheets attached to one photo in each stereo pair. These overlay sheets are retained as important permanent documentation for the study.
