Cylindrical shape

Three-Dimensional Ultrasonic Reflection Tomography of Cylindrical Shaped Specimens. 

Table 4 shows, the sources are available with physical sizes ranging from 1 mm x 1 mm up to 3 mm x 3 mm. They are produced from firmly compressed selenium pellets of cylindrical shape. The activities range up to 3 TBq or 80 Ci, which is the maximum allowed loading of the GammaMat SE portable isotope transport and working container, as well as the Source Projector M-Se crawler camera. 

The truncated octahedron and the rhombic dodecahedron provide periodic cells that are approximately spherical and so may be more appropriate for simulations of spherical molecules. The distance between adjacent cells in the truncated octahedron or the rhombic df)decahedron is larger than the conventional cube for a system with a given number of particles and so a simulation using one of the spherical cells will require fewer particles than a comparable simulation using a cubic cell. Of the two approximately spherical cells, the truncated octahedron is often preferred as it is somewhat easier to program. The hexagonal prism can be used to simulate molecules with a cylindrical shape such as DNA. 

Particle shape is also important. Disk-shaped as well as cylindrical-shaped conductors have a high response because large induced current loops are formed. Small randomly shaped conductors, such as those present in cmshed slag, also respond favorably. Sphere-shaped particles generate small-current loops, however, and do not have a high response. Multiple-current loops occur in conductors that have irregular bends, producing counteractive forces that tend to nullify each other. 

Atmospheric Tanks The term atmospheric tank as used here applies to any tank that is designed to be used within plus or minus several hundred pascals (a few pounds per square foot) of atmospheric pressure. It may be either open to the atmosphere or enclosed. Minimum cost is usually obtained with a vertical cylindrical shape and a relatively flat bottom at ground level. 

A vaiiation of the basic cylindrical shape is the multicone drum which contains a series of compartments formed by annular baffles [Stirling, in Knepper (ed.), Agg/nm rarin/1, Interscience, New York, 1962]. 

Advantages of the drum are protection of contents, ease of reclosure, and appreciable reuse-resale value. A serious limitation is the inefficient use of space because of the cylindrical shape, which results in high storage and transportation costs. To overcome this, a fiber drrtm with a square cross section (Ro-Con drum) and the brtlk corrugated bag in box have been developed.

Pelleted Activated Carbon - extruded and cylindrical shaped with diameters from 0.8 to 5 mm. These are mainly used for gas phase applications because of their low pressure drop, high mechanical strength and low dust content. 

We produced multilayer tubes with diameters between 20 A and 70 A and up to 2000 A in length [4]. An STM image of such tubes is shown in Fig. 3. The cylindrical shapes are well displayed. 

It is assumed in the above-mentioned methods that the influence of confined space on the supplied jet can be described by the reduction of the axial component and the value as for jet development in the counterflow. The value of i/,. is assumed to be the same throughout each cross-section but variable along the jet length. The value of can be found from the continuity equation, which in the case of jet distribution in a space of cylindrical shape can be presented as... 

A psychrometer measures the dry-bulb and wet-bulb temperatures simultaneously. The measurement of the wet-bulb temperature is achieved by means of a wet wick placed over the thermometer bulb. The thermometer can be practically of any type. A cylindrically shaped sensor is preferred. The wet-bulb temperaturesensing element, covered with the wick, and the dry-bulb temperature sensor, are placed in the airstream to be measured. The stream, generated by a small fan, should have a velocity of 3-5 m s and can be either transverse or axial. The...

At a critical length that depends on relative laminate thickness, the deformation solution trifurcates at point T, i.e., above the critical length, three possible room-temperature shapes exist (1) a saddle shape, (2) a cylindrical shape with Kj, = -i- k and Ky = 0, and (3) a cylindrical shape with k, = 0 and Ky = - k. For this 102/902)x laminate, the critical length is 35 mm. 

Metal Jacket—This type is primarily used on piping, heat exchangers, and other cylindrical shapes. 

Combustion behavior differed in some respects between continuous and instantaneous spills, and also between LNG and refrigerated liquid propane. For continuous spills, a short period of premixed burning occurred immediately after ignition. This was characterized by a weakly luminous flame, and was followed by combustion of the fuel-rich portions of the plume, which burned with a rather low, bright yellow flame. Hame height increased markedly as soon as the fire burned back to the liquid pool at the spill point, and assumed the tilted, cylindrical shape that is characteristic of a pool fire.

To account for the fact that the blast wave from the vessel will not be perfectly symmetrical, P, and 7 are adjusted, depending on R. To account for the vessel s placement slightly above ground level, P is multiplied by 1.1. To account for the vessel s cylindrical shape, P, is multiplied by 1.6 and 7 is multiplied by 1.1. Thus,... 

Springs made from coils of wire are used to store elastic energy which is a form of potential energy. The most common type of spring is cylindrically shaped, with coils evenly spaced and of the same diameter. A ballpoint pen uses a coil spring to hold the point in place for writing and to return it to the case for protection. 

Cylindrical bearings have solid or helically wound hollow cylindrically shaped rollers, which have an approximate length diameter ratio ranging from 1 1 to 1 3. They normally are used for heavy radial loads beyond the capacities of comparably sized radial ball bearings. 

In addition to alkyl-substituted derivatives, soluble PPPs 6 are also known today containing alkoxy groups as well as ionic side groups (carboxy and sulfonic acid functions) [18]. Schliiter et al. recently described the generation of soluble PPPs decorated with densely packed stcrically demanding dendrons on the formation of cylindrically shaped dendrimers, so-called cylinder dendrimers ] 19]. 

The cylindrical shape of a burnable object may not be intimately associated with its flammability after all. 

Concentricity Term to describe two circles or cylindrical shapes having a common center and common axis, such as the inside or outside diameters of a barrel or outside diameters of the surface and bearing surfaces of a screw. Deviation from concentricity is referred to as runout. Also refers to the relationship of all inside dimensions to all outside dimensions usually expressed in thousands of inch or millimeter FIM (full indicator movement). Deviation from concentricity is usually referred to as a runout. The concentricity should allow for the maximum part tolerance. The geometry of the part should help indicate the tolerance applied.
