Container nesting

Abstract—Experimental and theoretical studies of the vibrational modes of carbon nanotubes are reviewed. The closing of a 2D graphene sheet into a tubule is found to lead to several new infrared (IR)- and Raman-active modes. The number of these modes is found to depend on the tubule symmetry and not on the diameter. Their diameter-dependent frequencies are calculated using a zone-folding model. Results of Raman scattering studies on arc-derived carbons containing nested or single-wall nanotubes are discussed. They are compared to theory and to that observed for other sp carbons also present in the sample.

Kastner et al. [25] also reported Raman spectra of cathode core material containing nested tubules. The spectral features were all identified with tubules, including weak D-band scattering for which the laser excitation frequency dependence was studied. The authors attribute some of the D-band scattering to curvature in the tube walls. As discussed above, Bacsa et al. [26] reported recently the results of Raman studies on oxidatively purified tubes. Their spectrum is similar to that of Hiura et al. [23], in that it shows very weak D-band scattering. Values for the frequencies of all the first- and second-order Raman features reported for these nested tubule studies are also collected in Table 1. 

IF(e) THEN—Block if, where e is a logical expression, followed by a sequence of statements and completed by an ENDIF statement. The block may include sub-blocks introduced by one or more ELSEIF statements and/or one ELSE statement and all sub-blocks may contain nested IF-THEN-ELSE blocks within them. For example,... 

Eggs of migratory waterfowl seem to be especially sensitive to paraquat at recommended application rates in an oil vehicle, but were significantly more resistant to the same dose applied in water (Table 22.6). Application of paraquat in oil solution appears contraindicated in areas containing nesting waterfowl. 

Semantic rules are expressed as templates a dialect contains nested packages for its semantic rules. Each rule translates a slightly higher-level notation into its equivalent lower-level one. Here, any line between two type boxes that contains an explicit stereotype means the same as inverse attributes (see Figure 9.41). So what should an association line mean if it has no stereotype tag To define a default, you identify the untagged feature with the appropriate tag9 (see Figure 9.42). 

Within each arena there were two hay bales containing nest boxes. At the opposite end of the arena there was a water font and nearby a balance weigh-head. The balance weigh-head was connected to a PC recording any activity on the balances. Five food bowls, containing ground maintenance diet (Special Diet Services, Witham, Essex, UK), were distributed in each arena so that all four arenas were laid out identically. These food bowls were refilled daily, as was the water font. 

Compared with the above systems, the most important feature of the Cyber system is to achieve to exploit both potential concurrency and alternation at the same time in a simple and systematical way, by considering data dependencies and control structure in behavioral description. Therefore, it can synthesize more efficient control and more completely resource sharing from description containing nested conditional branchings and loops while maintaining the same ability to exploit potential concurrency with other system, and without incresise of computational complexity. Moreover, all possible paths for conditional branches are scheduled optimally. 

However, each branch of conditional branches should have its individual sequence suitable for itself. This could be done by scheduling each path separatedly. Nevertheless, such approaches are weak in exploiting global potential parallelism. In addition, they cannot search for the possibilities that branches are executed before the conditionals are resolved. The Cyber system can generate such efficient control sequences in simple method for CDFGs containing nested conditional branches. 

The LN2 is poured into a container called a dewar, which consists of two containers nested within each other separated by a vacuum. The liquid nitrogen is poured into a hole in the top of the dewar, and it may take several minutes for some of the LN2 to boil off as the dewar is chilled to temperature. It may take upwards of a liter of LN2 to accomplish this task. Once the dewar is cooled and filled, it will typically stay chilled for 8 hours, so the detector usually only needs to be filled once per work day. In theory, MCT detectors can be used at room temperature, but they will give very noisy spectra they work best when cooled to LN2 temperatures. The problem... 

Smaller amounts of phosphoms, or elemental phosphoms-containing materials, are also shipped in 115-L (30-gal) dmms that are DOT regulated (U.S. DOT lAl or 1A2 classification) and have thick shells and special gaskets and fittings for protection. Quantities up to 0.5 kg (1 lb) are allowed for shipping in two hermetically sealed (soldered), nested cans inside a wooden box where the empty space is filled with vermiculite (U.S. DOT 4C1, 4C2, 4D, or 4F classification). AH air transportation of elemental P, both U.S. and international, was prohibited beginning in 1992. 

Constant-pressure calorimetry requires only a thermally insulated container and a thermometer. A simple, inexpensive constant-pressure calorimeter can be made using two nested Styrofoam cups. Figure 6-16 shows an example. The inner cup holds the water bath, a magnetic stir bar, and the reactants. The thermometer is inserted through the cover. The outer cup provides extra thermal insulation. 

Minimize overall number of steps and stages preferably using nested MCRs as far as possible as the main strategy in a synthetic plan to a complex target. Overall convergence is maximized dramatically if a plan contains a late-stage MCR that involves components that are themselves terminal products of independent parallel linear sequences.
