Role In Successful Production Research Articles

Vegetative Propagation of Enterolobium cyclocarpum (Jacq.) Griseb. by Coppice Shoot Cuttings

Experiments were carried out to induce rooting on coppice shoot cuttings of Enterolobium cyclocarpum with the aid of auxins. Auxin treatments stimulated sprouting of cuttings in almost all seasons, but only cuttings prepared in January-March responded for rooting. Highest percentage (60) of rooting was obtained with IBA 100 ppm followed by 200 ppm (30%). IAA treated cuttings showed rooting only in 20 percent. No rooting was recorded either in control or in NAA treated cuttings. Cuttings having diameter of 1.5 cm and above responded well. The results demonstrated that season of preparation of cuttings, auxin concentration and thickness of the cuttings play significant role in successful production of propagules.

Molded neoprene liner pads for the poseidon missile launcher

AbstractNeoprene formulations and mechanical designs have been developed to meet special operational requirements for the Poseidon Missile Launch System liner. The liner supports the missile in an aligned position, provides shock mitigation, reacts properly with the missile during launch, and damps vibrations. Operational requirements include static and dynamic compressive stiffness, damping, and water drainability. A mechanical design was evolved that utilized notched, prebuckled struts as supporting members. Compression–deflection characteristics were modified by simultaneous changes in geometrical design and polymer formulation. A study of the effects of variations in polymer compounding and mechanical design on the compressive stiffness, rate sensitivity of the compression–deflection characteristics, and vibrational damping is described. Mold release agents and their role in successful production are discussed.
