Continuous thread

In the extensive literature on polymer drag reduction, it has occasionally been reported that a continuous thread of a high-concentration polymer solution injected into the axis of a pipe produces a drag-reduction effect on the water flow in the pipe [856]. The thread seems to persist through the length of the pipe and little, if any, diffusion of polymer to the walls of the pipe is apparent. 

Stated differently, the third ingredient calls for an understanding of the evolution of Anglo-Saxon law and its subsequent adaptation and modification in America. Throughout this evolution runs a continuous thread of concern for just, fair and humane treatment of those fellow men who become subjects of litigation. 

The anisotropy of the coil has been calculated for other models of the macromolecule. Expressions for the anisotropy coefficient are known in the case where the macromolecule has been represented schematically by a continuous thread (the persistence length model) (Gotlib 1964 Zgaevskii and Pokrovskii 1970) and also in the case where the microstructure of the macromolecules has been specified. In the latter case, the anisotropy coefficient of the macromolecule is expressed in terms of the bond polarisabilities and other microcharacteristics of the macromolecule (Flory 1969). 

If the extrusion profile is a tiny cylinder, the obtained product is a continuous thread for textile applications. The industrial name of this product is Rayon , or artificial silk . A brilliant fabric with good dying properties is thus obtained. 

Composites with filler concentrations close to the percolation threshold exhibit conductivity which is sensitive to compressive deformation, since this brings the metal particles into contact, thereby forming percolation pathways. This sensitivity has been exploited especially in anisotropic composites. These are made by prealigning the metal particles with either electric or magnetic fields. This alignment is identical with that produced by external fields in electro- and magneto-rheological fluids where at a critical field continuous threads of... 

The acid chloride is dissolved, for example, in hexane, and the diamine in water along with some NaOH to soak up the HCl. The aqueous layer is gently poured on top of the diamine solution. The reactants diffuse to the interface, where they react rapidly to form a polymer film. The resulting polymer is insoluble in both phases and can be drawn off in the form of a rope. The continuous thread or rope can be wound on a windlass until one or the other of the two reactants is exhausted (Fig. 14.24). This polyamide has found applications in sport equipment and bristles for brushes. 

Silk is a fibrous protein produced by several insect species. Commercially, silk is produced from the cocoon stage larvae of the moth caterpillar Bombyx mori, as it has been, in China, for some 4500 years. A single cocoon produces a continuous thread up to 1 km in length, and the protein fibroin contains large amounts of glycine, alanine, tyrosine, proline and serine The peptide chains are arranged in anti-parallel P-sheets which make up the hierarchical structure of the crystalline silk fibres. A number of spiders also produce silk webs, although the fibroin structure is rather different to that from silk worms. 

The silkworm spins the whole of its cocoon without a stop and the silk therefore is a continuous thread. One cocoon may contain about three thousand yards of silk and about one thousand cocoons would be required to produce 4 oz of useful thread. The spinning of the cocoon takes 3 to 4 days and when it is complete the worm changes into a pupa which may be either male or female. The cocoons producing males are somewhat smaller and more cylindrical in shape than those from which the females emerge (see Fig. 5.24). Although the two glands join at a common orifice they produce separate filaments known as... 

Table 11.2 applies to conventional continuous threaded preformed screw closures as applied to glass, plastic or metal containers, but is also relevant to multistart and lug type finishes. Certain features on the container have to be matched against the closure.

In most works the preexecution helper thread is created and disposed by the main thread explicitly. During its lifetime it prefetches a single item, and then terminates. Instead of trigger points and short-lived helper threads, we propose that the helper thread be a continuous thread. In order for the preexecution engine to be of use.
