Irregular plate

Gram-negative halobacteria comprise extremely halophilic rods and irregular plates [108]. Their cell envelopes consist solely of S-layers made up of glycoproteins. 

Differential Scanning Calorimeter (DSC) was used by Rogers and Dinegar [165] in combination with X-ray and microscopy to find the reason for ano-lous behaviour in the heat of fusion of PF.TN crystallized by different meth- . Microscopy revealed the existence of at least three crystal habits of PETN ) ctragonal (2) needle, (3) irregular plates. Their heats of fusion A//t were ... 

The process of precleaning the plates and carrying out repeated measurements is work-intensive, but this is partly made up for by the fact, that it is no longer necessary to apply several spots of a sample, as there is no longer any uncertainty resulting from the irregular plate structure.

Within the posterior pelvic compartment all components of the levator ani muscle are to he found the puhococcygeus muscles and the iliococcygeus muscles constitute an irregular plate and insert into the coccyx where they overlap each other in a staggered arrangement (Fig. 1.5). The inferior component, the puhorectalis muscles, do not insert into any skeletal...

When the explosion-bonding process distorts the composite so that its flatness does not meet standard flatness specifications, it is reflattened on a press or roUer leveler (ASME SA20). However, press-flattened plates sometimes contain localized irregularities which do not exceed the specified limits but which, generally, do not occur in roU-flattened products. 

Figure 14.10 shows the end profile of a sectioned stack plate with deep, irregularly shaped casting voids at the intersection of walls. Sectioning through these void zones revealed deep internal tunnel porosity (Fig. 14.11). When viewed under a low-power microscope, the contours of porous areas showed distinct solidification features (dendrites).

It is clear from examination of the fracture surface and weld cross sections that the weld was improperly formed, resulting in an irregular plane of unbonded metal. The smoothly rippled, spherical contours in some regions of the fractured area are evidence of solidification of the weld metal along a free surface that was not in contact with the plate. Substantial porosity is apparent. 

Stiffnesses for single-layered configurations are treated first to provide a baseline for subsequent discussion. Such stiffnesses should be recognizable in terms of concepts previously encountered by the reader in his study of plates and shells. Next, laminates that are symmetric about their middle surface are discussed and classified. Then, laminates with laminae that are antisymmetrically arranged about their middle surface are described. Finally, laminates with complete lack of middle-surface symmetry, i.e., unsymmetric laminates, are discussed. For all laminates, the question of laminae thicknesses arises. Regular laminates have equal-thickness laminae, and irregular laminates have non-equal-thickness laminae. 

Deposit uniformity The uniformity of a deposit is an important factor in its overall corrosion resistance and is a function of geometrical factors and the throwing power of the plating solution. A distinction is made here between macro-throwing power, which refers to distribution over relatively large-scale profiles, and micro-throwing power, which relates to smaller irregularities... 

The copper cyanide bath has excellent macro-throwing power and is chosen whenever irregular-shaped parts are to be plated. The sulphate bath is not inferior when parts with very narrow recesses, i.e. with width of opening less than 6 mm, are to be plated, although its macro-throwing power is...
