Adhering thread

Material. Protector material shall contain no compounds capable of causing corrosion or promoting adherence of the protectors of the threads and shall be suitable for service temperature (-50 to +150°F) (-46 to +66°C). [Pg.1147]

Successful applications of the SPMD technology under a wide variety of field conditions have been demonstrated by a number of researchers (see Appendix B or CERC, 2004). The common threads among successful applications of SPMDs are a basic understanding of potential sources of sample contamination and losses, the functional aspects of the SPMD technique, and the adherence to sound sampling approaches and good laboratory practices. [Pg.98]

Neutrophil. A granular leukocyte, having a nucleus with three to five lobes connected by slender threads of chromatin, and cytoplasm containing fine inconspicuous granules. Neutrophils have the properties of chemotaxis adherence to immune complexes, and phagocytosis. [Pg.572]

By itself a subject of study, metallic yam used in the past comes in a number of varieties that reflect the level of technology and trade of the time. A majority of metallic threads has been made into yarn by cutting prepared metallic material into strips that were then wound around a core thread of silk or linen. The metallic materials used were either gold or silver leaf adhered to membrane, parchment, leather, or paper or plain soft metal. Membrane is adversely affected by water and... [Pg.170]

The desmosomal junction is a morphological entity that is very distinct from adherence junctions involving classical cadherins [44]. The plasma membrane domains of apposing cells are separated by a 20-30 nm thick layer, which in cross section in electron micrographs reveals a midline structure and electron-dense threads stretching laterally from the midline back to the plasma membrane. The cytoplasmic face of each membrane domain is covered with an electron-dense plaque to which bundles of intermediate filaments attach, rather than the actin filaments present in adherence junctions containing classical cadherins. In most epithelia the intermediate filaments are based on keratins but rarer examples of desmosomal junctions coupled into intermediate filaments of the vimentin or desmin type are known [5]. [Pg.514]

Particles of the explosive are usually found adhering to the pipe cap or to the pipe threads in pipe bombs. This occurs either by handling during the construction or being impacted into the metal by the force of the explosion. [Pg.579]

The 14 and 1C threads uro not always adhered to. A house in Philadelphia say they usi laps of 13 threads, and a firm in Pittsburg advertise taps of 20 threads per inch. [Pg.333]

The capacity of pathogenic bacteria to adhere to mucosal membranes has been exploited in the modification of new mucoadhesive polymers. The ability of bacteria to adhere to a specific target is rooted from particular cell-surface components or appendages, known as fimbriae, which promote adhesion to other cells or inanimate surfaces. Fimbriae are extracellular, long thread-like protein polymers of bacteria that play a major role in many diseases. It has been reported that Escherichia coli adheres specifically to the lymphoid follicle epithelium of the ileal Peyer s patch in rabbits. Similarly, different staphylococci possess the ability to adhere specifically to the surface of mucus gel layers and not mucus-free surfaces. Thus, polymers have been modified by the attachment of these fimbriae to enhance mucoadhesion. An attachment protein derived from E. coli, K99-fimbriae, has been covalently attached to polyacrylic acid networks in an attempt to provide a novel polymer with enhanced adhesive properties (Figure 52.7). ... [Pg.1246]

It is meaningful to study the thermal properties of spider s silk thread from the heat resistant point of view since spider silks adhere to some objects such as rock and metal and may be heat-stable even at high temperatures between 60 °C and 100 °C. However, the thermal properties have not previously been studied, probably due to the difficulty in collecting draglines. Spider threads have been studied mainly from the morphological point of view. ... [Pg.297]

After the desired period of incubation, fix the embryo by flooding with methanol (for most immunological detection procedures), Zenker s fixative (for Feulgen-Rossenbeck staining), or in 4% formaldehyde in PBS (for in-situ hybridization and most other procedures). In the case of methanol or Zenker s, which are rapid fixatives, it is advantageous to submerge the cultured embryo in saline, then detach it from the vitelline membrane and transfer it to a clean dish with saline prior to fixation. Otherwise, the embryo adheres permanently to the membrane and the fixative denatures the albumen, generating threads of protein that tend to stick to the embryo. Formaldehyde can be poured directly onto the embryo, provided that the embryo is detached from the membrane within a few minutes. [Pg.274]

Holes can be molded-in rotational molded parts by using core pins to which the resin does not adhere. Bosses can be molded by molding a raised cylinder such as that at T. The tip of the cylinder is then cut off to leave an opening. The diameter of this type of hole should be at least 5 times the nominal wall thickness (D > 5W). Threads, both inside and outside, such as the one at S, are readily rotational molded. Recommended tolerances are provided in Table 8.17 (see Fig. 8.37). [Pg.708]

Bolas spiders, Mastophora spp., capture prey by swinging a sticky ball on the end of a thread at passing insects. Once struck, the prey adheres to the ball whereupon the spider descends the connecting strand and feeds on the prey. The success of such a short-range means of attack, requires that a substantial number of prey passes within the range of the spider s attack. Eberhard (1977)... [Pg.285]

Another development to prevent stent dislocation is the Reynders stent (Reynders Medical Supply, Lennik, Belgium), which is a screw-thread plastic prosthesis. The stent clicks into the tracheal cartilage rings, thus providing better airway-wall adherence. It also has a greater rigidity than sificone stents (Noppen et al. 1996,1999). [Pg.248]

Fig. 8 The three families of oligorotaxanes, exemplified by compounds derived from a heptameric DNP thread. The rotaxanes moods depend on their adherence to a selection rule forbidding CBPOT " to occupy adjacent DNP sites. Whereas Confiased rotaxanes can adopt multiple stable translational isomers and Frustrated rotaxanes cannot obey the rule at all, Happy rotaxanes express a single rule-compliant isomer...
