Transverse section

The tube was transversely sectioned, polished, and viewed with various microscopes. Large porous corrosion-product plugs extended entirely through the 0.050-in. (0.13-cm)-thick wall (Fig. 13.10B). The depressions contained 94% copper, 5% zinc, and 1% tin. 

In hardwoods, morphological structural elements in longitudinal series comprise the segmented structure termed vessel . Vessels, which are exposed in transverse section, constitute about 10-46% of the stem volume in deciduous hardwoods and are cells of relatively large diameters (50-300 p.m). Vessels have in short the appearance of open vertical tubes within the wood structure because their end walls have partially dissolved. By comparison, the hardwood vessel diameter can be as much a 10 times the diameter of a softwood fiber.

The coatings produced by metal spraying have an unusual structure which is characteristic of the method of formation. They are composed of small particles usually not more than 0-01 mm in diameter which, having reached the surface in the molten condition, have splashed outwards and then solidified. Figure 12.27 (left) shows in section the irregular form of the flattened particles. In transverse section the surface profile is undulating (Fig. 12.27 (right)).

The EMSIL obtained with the purified EPG on transverse sections of barley leaf epidermal cells taken pependicular to the long axis of the cells and anticlinal to the leaf surface, revealed that EPG substrate is localized primarily in the cell comers and middle lamella of these cells (Fig. 1). 

Figure 1. Transverse section of barley leaf epidermal cells taken perpendicular to the long axis of the cells and anticlinal to the leaf surface. The section has been labeled by the EMSIL technique (see Methods) utilizing purified C. sativus endopolygalacturonase and monoclonal antibody EPG-4, which is specific for this enzyme, in order to localize the substrate of the enzyme at the typical site penetrated by the fungal pathogen. Bar = 1 pm. Inset Comparable cell wall region as in Fig. 1 but labeled with monoclonal antibody JIM 5 to localize non-esterified pectin. Bar = 1 pm. Note the identical labeling patterns obtained with either method.

Fig. 5.5.7 A 2D slice through a H 3D MR image of the fixed-bed of catalyst particles. The catalyst particles appear as black fluid within the inter-particle space is indicated by lighter shades. Chemical conversion within ten selected volumes within each of the three transverse sections indicated is investigated in Figures 5.5.9-5.5.11. The direction of superficial flow (z) is also shown.

Studies of this reaction have recently been extended to acquisition of a 3(4)D CSI dataset, shown in Figure 5.5.12 the grey scale indicates the extent of conversion. As expected from the 1(2)D CSI and volume selective imaging studies discussed earlier, conversion is seen to be heterogeneous within transverse sections through the bed at any position along the direction of superficial flow. 

TJ, tight junction LS, lateral space. b Tortuosity is the tortuous length of the lateral space divided by the height of the cell. All physical dimensions are measured by electron microscopy using transverse sections of cell monolayers. c Calculated as (cell height — TJ length) X tortuosity.

Fig. 7.5. A schematic indication of some of the different membrane separated compartments in an advanced cell. PEROX is a peroxisome MITOCHLORO is either a mitochondrion or a chloroplast CHROMO is a vesicle of, say, the chromaffin granule ENDO is a reticulum, e.g. the endoplasmic reticulum. Other compartments are lysosomes, vacuoles, calcisomes and so on. Localised metal concentrations are shown. The figure is of a transverse section. To appreciate a cell fully it is necessary to have serial plane sections in parallel along the. "-direction.

High Resolution Transmission Electron Microscopy (HRTEM, Philips CM20, 200 kV) was applied to get structural and nanotextural information on the fibers, by imaging the profile of the aromatic carbon layers in the 002-lattice fringe mode. A carbon fiber coated with pyrolytic carbon was incorporated in epoxy resin and a transverse section obtained by ultramicrotomy was deposited on a holey carbon film. An in-house made image analysis procedure was used to get quantitative data on the composite.

The axon contains scattered neurotubules and loosely packed neurofilaments interconnected by side-arm material. The astrocytic process contains a bundle of closely packed filaments with no cross-bridges, flanked by several microtubules. Sometimes, a lumen can be seen within a filament. X60,000.

Figure 6.2. Sketch of the section of a high-frequency apparatus, in which, inside the primary induction coil (the inductor), another water-cooled copper tube, acting as a sample-container and as a field concentrator , is enclosed. In this copper tube, here shown in its transversal section, a hollow is made, obtaining a cradle in which the sample is contained. The cool surface of this copper container generally is not attacked by the (albeit molten) alloy and promotes its fast solidification and cooling.

Dentin slices. Enamel-dentin specimens were prepared by drilling a hollow cylinder through the crowns of the incisors. Dentin slices (diameter 6 mm, thickness 0.50 mm) were made as transversal sections with a water-cooled diamond wire sawing machine (Well, model 3142 W. Ebner,...
