Metallic cylinder model

See under Smoke Floats Navy Sea Markers Type 0, Model 1, Model 2 were light metal cylinders with rounded nose and conical tail, provided with fins. They contd fine A1 dust with 6.5% Zri dust. On impact with water the plug in the nose was forced into the body forcing the tail portion to be freed from the body, thereby scattering Al-Zn pdr,... 

Type 93 A/Tk (Antitank) and A/P (Antipersonnel) Land Mine, known as Tape Measure Mine, was a light metal cylinder 6% inches diam and 1% inches high, filled with 2-lbs of cast PA and Booster of pressed PA. It was activated by pressure on Percussion Primer, located on top of Mine (pp 202—03, Fig 152). Described in Ref 7>, p 183 as Land Mine Model 93 (1933)... 

The 1-D concentric cylinder models described above have been extended to fiber-reinforced ceramics by Kervadec and Chermant,28,29 Adami,30 and Wu and Holmes 31 these analyses are similar in basic concept to the previous modeling efforts for metal matrix composites, but they incorporate the time-dependent nature of both fiber and matrix creep and, in some cases, interface creep. Further extension of the 1-D model to multiaxial stress states was made by Meyer et a/.,32-34 Wang et al.,35 and Wang and Chou.36 In the work by Meyer et al., 1-D fiber-composites under off-axis loading (with the loading direction at an angle to fiber axis) were analyzed with the... 

Sample Preparation for SEM. Samples for the scanning electron microscopy (SEM Model Joel JXA-8600) were prepared by first immersing the membrane into a liquid nitrogen. This made the membrane brittle. The membrane was broken into small pieces and some of the pieces were mounted on the metal cylinder that forms part of the stage inside the microscope. The membrane was mounted such that its cross-section (or the broken face) was perpendicular to the electron beam. This way we were able to study the pore structure of the membrane directly. Our focus was to study the edge that was in contact with the bottom wall of the bottle. All membranes were coated with carbon to make them conductive prior to any microscopy work. 

This velocity profile is commonly called drag flow. It is used to model the flow of lubricant between sliding metal surfaces or the flow of polymer in extruders. A pressure-driven flow—typically in the opposite direction—is sometimes superimposed on the drag flow, but we will avoid this complication. Equation (8.51) also represents a limiting case of Couette flow (which is flow between coaxial cylinders, one of which is rotating) when the gap width is small. Equation (8.38) continues to govern convective diffusion in the flat-plate geometry, but the boundary conditions are different. The zero-flux condition applies at both walls, but there is no line of symmetry. Calculations must be made over the entire channel width and not just the half-width. 

Rats are placed onto a hot metal plate maintained at 52 °C surrounded by a Plexiglas cylinder (Height 26 cm Diameter 19 cm). The hot plate apparatus we use is provided by Apelex, 92220 Bagneux, France (Model DS37). The latency to the first foot-lick is measured (maximum 30 seconds).
