An indication of the elasticity of a non-Newtonian fluid is obtained by extending a fluid bridge between a pair of relatively movable surfaces. Additionally, provided are methods for the treatment of cancer, a neoplastic disease state andor a hyperproliferative disorder, and methods of inhibiting Heat Shock Protein 90. It includes a locking stressing mechanism, an energy-storing spring, a hollow plunger displaceable in a cylinder and a nozzle. The network switch can further include a memory configured to store a first forwarding database, and a plurality of aggregate zone entries within the first forwarding database. The adjustable portion is mounted for movement relative to the base portion in a contracting direction wherein the container engaging surfaces move relatively towards one another and an expanding direction wherein the container engaging surfaces move relatively away from one another, thus enabling receipt of containers of various sizes between the container engaging surfaces. In one embodiment, the E-block has a metal core of aluminum.
