Fig. 2. A portion of an unrolled cylinder with screw helicity. The broken line is parallel to the cylinder axis, and the cylindrical sheet has been cut along a generatrix (full line parallel to the cylinder axis), a and b are the unit vectors of the two-dimensional carbon layer in hybridization.

Fig. 4. Screw helicity the system of (P, O) coordinates used to describe Ihe orientation of the two-dimensional sp carbon layer in an unrolled cylindrical sheet whose edges are shown by the slanted unlabelled full lines. Closure of the cylinder is obtained by rolling the sheet around the direction of the cylinder axis given by the dotted line and superimposing hexagons A and B. The slanted dashed lines correspond to a continuous line of unbroken hexagons of the cylinder, and indicate the apparent angle of pitch /3.

Fig. 20. Schematic representation of the unrolled major groove of the MPD 7 helix showing the first hydration shell, consisting of all solvent molecules that are directly associated with base edge N and O atoms. Base atoms are labeled N4,04, N6,06 and N7 solvent peaks are numbered. Interatomic distances are given in Aup to 3,5 A represented by unbroken lines, between 3,5-4,1 A by dotted lines. The eight circles connected by double-lines represent the image of a spermine molecule bound to phosphate groups P2 and P22. There are 20 solvent molecules in a first hydration layer associated with N- and O-atoms l58)...

Stainless steel coil and sheet stock is unloaded and stored outdoors under protective cover. As it is needed, the coil stock is moved indoors by a forklift to one of six automatic tube mills where the sides of unrolled metal strips are curled up to form a continuous, cylindrical pipe. The seam of the resulting pipe is fused in an electric in-line welding operation. An abrasive saw is used to cut the continuously formed pipe to specified lengths sections of poorly welded pipe are cut away. 

Schmidt-Lantermann clefts are structures where the cytoplasmic surfaces of the myelin sheath have not compacted to form the major dense line and therefore contain Schwann or glial cell cytoplasm (Fig. 4-9). They are common in peripheral myelin but rare in the CNS. These inclusions of cytoplasm are present in each layer of myelin. The clefts can be visualized in the unrolled myelin sheet as tubes of cytoplasm similar to the tubes making up the lateral loops but in the middle regions of the sheet, rather than at the edges (Fig. 4-9). 

Hard rubber fire hoses are usually provided throughout the process area of a hydrocarbon facility. The coil of a hose on a hose reel presents a considerable friction loss factor to the flow of water through it. In some instances a fire water hose reel may not be completely unrolled from a reel before its use. Therefore it is prudent to conduct a hose reel flow test with a partial removal of the hose and full unreeling from it. The spray reaches of each scenario can then be fully evaluated and observed. 

The ease of unrolling a hose reel to the protected hazard should be tested. 

Scott et al. [53] and McFadden et al. [54] first described this mechanical interface in 1974 and 1976. A diagram of a commercialized moving belt interface is shown in Fig. 19.11. The interface first consisted of a spool of wire, which was unrolled off one spool and onto another. As the wire was wound from spool to spool, the effluent from a liquid chromatographic separation was applied to the wire. As the wire was transported through...

Dimensional Stability. The separator should lay flat and should not curl at the edges when unrolled, as this can greatly complicate cell assembly. The separator should also not shrink when exposed to electrolyte. The cell winding should not affect the porous structure in any adverse way. 

First ply or as vapor barrier under insulation. Coated on both sides with asphalt and surfaced on top side with fine mineral granules (2,9). k Product does not crack, tear, or cause damage upon being unrolled at 10—60°C.

The participants were Diaz, Valdes and Don Alejandro, who sat on a bench and watched over the others during the proceedings. The curandero and Diaz, who had taken laMarldi several times previously, each had doses prepared from 50 pairs of leaves. Valdes received a beginner s dose prepared from 20 pairs. They took the Salvia preparations around 22 30 h. The visitors shared a large cot while the shaman lay on apetate, or sleeping mat which was unrolled on the floor.
