Cross-cutting

To make sure that all contractors and subcontractors maintain a minimum level of safety performance, the client, or general or main contractor, should establish standards for compliance. During the project planning stage, affected prime contractors should have an opportunity to provide input and resolve differences. Cross-cut committees are encouraged to allow prime contractors to standardize or normalize such essential elements as procedures, permit systems, and training.

Once initiated, and provided the surface continues to be exposed to the environment, the process of hydration continues at a slow, but measurable rate. The adsorption of the water is accompanied by changes in the physical properties of the obsidian. The refractive index of the obsidian, for example, is altered as it becomes hydrated. If the obsidian was subjected to alternative wet and dry periods, successive hydrated layers are formed on the surface. The differences in refractive index between the bulk and the hydrated layer (or layers) creates an interface between the bulk and the hydrated layer, and between the layers, that stands out sharply when observing a cross-cut section of obsidian under a microscope (see Fig. 23). Thus the thickness of the hydrated layer, or layers, can be measured. 

Figure 3 presents results of adhesion for LBG1025/PVDF composites. As one can see, in the particular testing conditions, LBG1025 has a poor adhesion (100% of the coating has been removed by the Scotch tape even without a need to make cross-cut scratches on the surface of current collector).

The final chapter addresses the cross-cutting issue of materials processing for SOFC applications. The challenges in developing materials that satisfy the stringent materials property requirements is further complicated by the need to fabricate the materials in the desired shapes and with the desired microstructures. The production of a cost-effective SOFC requires compromises between materials properties and processing methods to produce materials with adequate properties at an acceptable cost.

The practical implementation of the Directive takes place by means of the development of a series of BAT Reference Documents (BREFs) which serve as guidance documents either for individual industrial sectors (such as the chlor-alkali industry) or, in the case of the so-called lateral BREFs , for cross-cutting activities. 

Cross-cut ( -cuf) According to ASTM D 3359, method B (ISO 2409), a lattice with 6 cuts in each direction is made in the film to the substrate. Then, pressure tape (TESAPACK 4287) is applied over the lattice and then removed, and adhesion is evaluated by comparison with descriptions and pictures. The method is used to establish whether the adhesion of the coating to the substrate may occur between the coats (adhesive break) or in the coating (cohesive break).

An important point to note is that the underfilm darkening is not associated with any fall off in film performance in terms of adhesion, cross-cut undercutting, blistering or exfoliation. 

In addition to Au, a variety of Au-Sb, Au-Ag and Bi-Te alloys accompanied post-D2 arsenopyrite precipitation. Au and Bi-Te alloys are also locally concentrated in the biotite-rich margins of tonalite dykes that were contaminated by the host sediments. These alloys also appear to be concentrated within the HGA and are locally associated with disseminated scheelite and F-apatite. The latter also occur in late-stage veins that cross-cut weakly foliated granodiorite stocks that lie immediately beneath the HGA. A combination of BSE and CL imaging reveals that precipitation of these post-D2 sulfides and alloys occurred within a micro-porosity network that records dissolution-precipitation reactions... 

Numerous aphanitic to fine-grained sannaite lamprophyres have been observed. They are dark grey to greenish, range in width from 15 cm to 3 m, and cross-cut the ZSSC, LMSC and Ottertail Formation. The lamprophyres all trend between ESE to WNW. 

The contacts between lamprophyres and the IRAC range from planar to very irregular. The lamprophyres typically exhibit a chilled margin. However, at both the hand sample and thin-section scale, a sannaite lamprophyre sample exhibits a cuspate boundary against a nepheline syenite dyke, indicative of two partially molten materials. Lamprophyre dykes cross-cutting syenitic dykes have also been observed. 

Three textural types of pyrite occur in all samples examined 1) early framboids or irregular masses, 2) isolated euhedra, and 3) pyrites with massive cores and spongy or porous rims (Fig. 1). Types 2 and 3 occur in both shale and cross-cutting to bedding parallel veins, whereas type 1 occurs in shale only. 

Type III mineralization consists of late carbonate quartz veins with minor sulfides (= 20%). These veins cross cut Type I mineralization. 

Upright veins cross-cut bedding in the host sedimentary rocks at a high angle, trend 075-090° and dip ca. 70-80°S. Jaclyn North veins roughly parallel bedding, similarly trend 075-090° and dip 35-45° N. 

This chapter is not intended to furnish a comprehensive review of the latest theoretical developments across all types of reaction and catalyst in heterogeneous catalysis. It will instead briefly survey two cross-cutting themes that have in recent years benefited substantially from theoretical insights, especially what first-principles DFT calculations have been able to explain and predict, and that are commanding substantial current interest the design of new catalysts aided by theoretical insights and the elucidation of the molecular level effects of reactive physiochemical environments on catalytic reactivity. The relatively simple and predictable structure of metals...
