Smoothing triangular

In the case of the cubic closed structured metal crystal, there are glide planes within the atomic layers in all directions, thus the mechanical attack can be repelled from many directions through the movement between atomic layers. The elementary cube itself allows the movement of smooth triangular layers in four directions, i.e. perpendicular to the four diagonal spaces. In comparison, the hexagonally closed structured metal crystal has only one direction of the triangular layer in the hexagonal unit cell. These metals are not very ductile and crumble to dust when force is applied. [Pg.107]

The full description of the deep chemical peel procedure is found in Chapter 8. Before the peeling, the subcision (subcutaneous incision) technique is used to free the fibrous bands from the base of the scars. For this purpose we use an i8-gauge 1.5-inch NoKor Admix needle (Becton Dickinson and Co). This needle has a triangular tip similar to No. 11 blade (Fig. 9.5). it allows smooth separation of fibrous cords. The needle is inserted through a skin surface, and its sharp edges are maneuvered under the defect to make subcutaneous cuts or incisions. The depression... [Pg.94]

In addition to the aforementioned methods, fiber cross-sectional shape is used to produce differences in appearance. Surface lobes can break up smoothness and reduce glitter, and triangular or T shapes can generate subtle sheen effects to fabrics and yams. The patent literature is filled with various cross-sectional shapes which have been used to provide visual and tactile effects that are not possible with natural fibers. [Pg.423]

Last, but by no means least, reference should be made to the use of proteins in nano-fabrication [492]. One approach is illustrated by the fabrication of a 1-nm-thick metal film with 15-nm-diameters holes, periodically arranged on a triangular protein lattice [493]. Advantage was taken of the 10-nm-thick, uniformly porous surface (or S) layer of the crystalline protein obtained from the thermophilic bacterium Sulfolobus acidocaldarius. The protein was adsorbed from a dilute solution onto a molecularly smooth carbon-film surface, metal coated by evaporation, and ion milled to give spatial ordering of holes with the same nanometer periodicity as the protein lattice [493]. [Pg.96]

EP is frequently defined nowadays as GPi (or medial GP) also in rodents, adopting in rodents the subdivision of the GP in two segments (cf. the rat atlases of Paxinos and Watson (1998) and Swanson (1992) cf. also the mouse atlases of Hof et al. (2000) and Paxinos and Franklin (2001)). The majority of neurons of both the GP divisions are large and fusiform or triangular, with very long, thick, smooth and sparsely branching dendrites (see for reviews Heimer et al., 1995, and Gerfen, 2004). The term ventral pallidum refers to the ventral or subcommissural part of the pallidal complex (see Section 7). [Pg.40]

All such points formed smooth curves when plotted on the three-component triangular graphs used for each system investigated except that of the potassium chloride-water-THF system. In the latter case, two solubility curves appeared which met in an invariant point. The solubility plots are shown in Figures 1, 2, and 3. [Pg.186]

Case II of Fig. 1 shows the cross-section of a pit formed by a preferential etch at a dislocation on a material whose planes form closed figures, such as the cubic system or the pyramidal planes of the hexagonal system. The relative etch rates are Rd > Ra > Ry F°r example, if the dislocation is normal to a 111 surface, triangular pyramidal pits will be formed. These pits have smooth, rather than terraced, sides as shown in Fig. 3. If, however, the dislocation line is at an angle to a ill surface, the triangular pyramidal pit is lopsided (Fig. [Pg.158]

It is of some importance to mention that the "waveform" pattern as defined by Gunning [8] cannot be comprehoided as a projection normal to the 221 plane of his model, which model resembles the P-PCS-structure. Among the possible candidates that we have investigated for the description of the PLB structure (the D-, P-, and G-PCS structures and four other cubic PMS s based structures), the D-PCS structure alone accounts for all structural features of the PLB that are available to us. Of particular value is the recognition of the prominent triangular-like structural elements of the D-surface, which have only been observed in the D-PCS structure. We should point out that the opposite case i.e. the lack of such triangular elements, does not exclude the D-PCS in a structural evaluation of a cubic membrane, and we have encoxmtered cases in which the aspect of the D-cubic membrane is smoothly curved. [Pg.264]
