Layers overlap

Security layers of protection Also known as concentric rings of protection, a concept of providing multiple independent and overlapping layers of protection in depth. For security purposes, this may include various layers of protection such as countersurveillance, counterintelligence, physical security, and cyber security.

It is important to remember that the overlapping layers in which we are interested are solutions of pendant or looped polymer chains surrounded by solvent. There is room for interpenetration of the two domains, but the process is uphill thermodynamically. 

The combined results of all the electron microscopic measurements alluded to in this section as well as results that had been reported by other laboratories present a model for the holoenzyme CFo F, embedded in a lipid bilayer, as shown in the lower portion of Fig. 6 (D). In this model, the a- and P-subunits in CFi are shown distributed in two overlapping layers, with the a-subunits closer to CFq. The smaller y-, 8- and e-subunits are asymmetrically distributed in the center surrounded by the a- and P-subunits. In the upper portion of Fig. 6 (D) is a top view of CFj drawn on the basis of signal-enhanced projections, such as those shown in Fig. 6 (B) and (C). The total length of CFq was found to be 8.3 nm. Although there was a lack of definitive information regarding subunits I, II and IV at the time, they were positioned above and below subunit III. The cylinder formed by the 8-kDa component of subunit III was considered to be the main pathway for proton translocation. The function of subunits I, II and IV in establishing a pathway for proton translocation or forbinding CF, was unclear at the time. ...

Fig. 4 Porphyrin-sieve-type clathrate consisting of stacked networks of hydrogen-bonded MTCPP moieties, showing four to 5 overlapping layers. The van der Waals width of the interporphyrin channels propagating through the crystal and accessible to other species is about 1.5 (View this art in...

Accumulators can provide specialty products, an example being clear stripping systems. Two separately extruded melts enter the head and fuse together prior to exiting. Like overlapping layer formation of the parison, this feature also provides a positive way to strengthen weld lines. 

XRD analysis was as well performed on crosslinked nanocomposites based on synthetic poly(isoprene) and containing CNT." The (002) reflection, reported in Figure 2.4b, was also observed in the pattern of the nanocomposite. Analogously to what reported above for nanocomposites with nano-G, the peak width analysis led to calculate a higher number of overlapped layers and... 

Polypropylene (PP) was blended with ethylene-co-vinyl alcohol (EVAL) and maleated polypropylene (PP-MA). The blends were extruded through a sheeting die that engendered overlapping layers of EVAL. Their presence reduced permeability by gases or liquids through the PP wall ...

The many forms of calcium carbonate described clockwise from top). An abalone shell is composed of thin overlapping layers of calcium carbonate, interspersed with a protein (a class of macromolecules described in Chapter 22). Limestone is a mixture of calcium carbonate and other compounds found in sedimentary rocks. Aragonite is one of the crystalline solid forms of calcium carbonate, characterized by the arrangement of carbonate ions in two planes that point in opposite directions. Blackboard chalk is often incorrectly believed to be made from the mineral chalk, which is a form of calcium carbonate, but, in fact, it is made from calcium sulfate. Iceland spar is the clear form of the mineral calcite, which is calcium carbonate arranged in a different crystal structure from that of aragonite.
