Vessel heads can be made from explosion-bonded clads, either by conventional cold- or by hot-forming techniques. The latter involves thermal exposure and is equivalent in effect to a heat treatment. The backing metal properties, bond continuity, and bond strength are guaranteed to the same specifications as the composite from which the head is formed. AppHcations such as chemical-process vessels and transition joints represent approximately 90% of the industrial use of explosion cladding. 

Under some citcumstances the crack tip stress intensity is different than far-field stresses would indicate because of microstmctural effects behind the crack tip, such as fibers, whiskers, and bridging grains. Often far-field values indicate the crack is propagating at a stress intensity value higher than Kj and this apparent value usually increases as crack length increases. In spite of indications to the contrary, bonds continue to break at the same value of the stress intensity however, the crack tip is being shielded from some of the appHed stress intensity. To minimize confusion about Kj it has been suggested that the farfield value of the stress intensity be called When there are no microstmctural features that effectively reduce the crack tip stress intensity,...

The most common adhesive system used for bonding continuous fibers and fabrics to rubber is resorcinol-formaldehyde latex (RFL) system. In general, RFL system is a water-based material. Different lattices including nitrile and SBR are used as the latex for the adhesive system. 2-Vinylpyridine-butadiene-styrene is the common latex used in the adhesive recipe. RFL system is widely being used in tires, diaphragms, power transmission belts, hoses, and conveyor belts because of its dynamic properties, adhesion, heat resistance, and the capacity to bond a wide range of fabrics and mbbers. 

In summary, as the human-animal companies bond continues to grow and gain importance, veterinarians are expected to practice a higher quality of medicine. The pharmacist is in a position to assist the veterinarian in obtaining this goal. Familiarity with veterinary medicine, dosage forms, and animal drugs is useful to the pharmacist who acts as an advisor, reference source, and compounder to the veterinarian, the public, and members of the health care team.

The chemistry of the Pm-halogen bond continues to attract a good deal of attention. Unfortunately, much of the effort is undistinguished, and the best work has often been concerned with tidying up old reactions, rather than with breaking new ground. 

Attack on Unsaturated Carbon. The annual addition of phosphites to every variety of activated double bond continues. These include nitro-alkenes,9 a/S-unsaturated carboxylic acid derivatives,10 maleimides,11 fulvenes,12 and pyridinium salts.13 The reaction of diethyl phosphite with keten 0,N-, S,N, and Al,AT-acetals has been used to prepare the enamine phosphonates (19).14... 

Fig. 16. An unusual interrupted helix from subtilisin (residues 62-86), in which the helical hydrogen bonds continue to a final tum that is formed by a separate piece of main chain. Such interrupted helices (broken on one side of the double helix) are apparently a fundamental feature of nucleic acid structure as illustrated by tRNA, but are exceedingly rare in protein structure.
