One of the most popular techniques used for determining the hardness of a material is the Mohs scale that consists of a qualitative but an arbitrary hardness index scheme ranging from extremely soft materials (value of 1 Moh) to very hard materials such as diamond (10 Moh). Other techniques that are often employed for measuring hardness of substances are developed by Rockwell [72], Brinell [72], Knoop, and Vickers [73]. Over the years, more quantitative methods such as nanoindentation [74] have been developed. This technique applies a small and a controllable load on to the substrate with a probe. The depth of penetration along with a known geometry of the probe provides an indirect way to measure the area of contact at full penetration, which is then used to determine the hardness. The hardness is determined by the ratio of the total force to the contact area. Table 7.2 lists the bulk hardness of different materials, metal films, and abrasive particles, in both Moh and microhardness scales [75]. 

The relative polarity of solvents in the polarity index scheme differs from that in the solubility parameter scheme. For example, using 8 values methanol is more polar than acetonitrile whereas using Snyder s polarity index, acetonitrile is more polar than methanol. Practical experience suggests that methanol is more polar than acetonitrile and therefore supports the solubility parameter approach.

The rather limited crystallinity of PPP produced by the Kovacic route, which can be increased to 60% by annealing above 400°C, has been an obstacle to the determination of the unit cell. Well-oriented diffraction patterns have only been obtained in electron diffraction studies. Nonetheless, Kovacic et al. [169] have laid down the basic aspects of the structure and its problems in their very original work, which included an x-ray study. Their indexing scheme for the reflections has been verified in several later studies. The authors propose a pseudo-orthogonal cell with two chains passing through, and dimensions o = 7.81 A, h =...

Note, the continuity condition of concentration at the junction, y (N + 2) = is not listed as part of Eqs. 12.158, and we shall see that this is taken care of in the global indexing scheme.

One of the overlooked contributions that Referee 2 mentioned is the pioneering study in the numerical characterization of DNA, the paper by Raychaudhury and Nandy, Indexing Scheme and Similarity Measures for Macromolecular Sequences [9], We agree that this may be a pioneering study in the numerical qualitative characterization of DNA, but it does not represent the numerical quantitative characterization of DNA, a contribution to solving problems relevant for quantitative graphical bioinformatics. We claim that the first numerical quantitative characterization of DNA is the paper by Randid, Vracko, Nandy, and Basak [4].

The volume collapse of over 10% required by the indexing scheme of Akella et al. (1986) is rather large, while the much smaller volume discontinuity required by the -Np-type indexing fits perfectly to the available shock-wave data (Carter et al. 1975) for Sc at pressures over 25GPa. 

In this context, India has made important advances by implementing indexed schemes for crop insurance, successful in great part thanks to the governmental policy that requires the insurance sector to service the low-income populations (Mechler et al. 2006 Gine et al. 2010). Other countries in Africa, Asia, and Latin America are making use of similar schemes (Ibarra 2009). 

Here, uppercase U, V, and W indices are associated with the three-index scheme (instead of u, V, and w as previously), whereas lowercase u, v, f, and w correlate with the Miller-Bravais four-index system. For example, using these equations, the [010] direction becomes [1210]. Several directions have been drawn in the hexagonal unit cell of Figure 3.9. 

Point Coordinates Crystallographic points, directions, and planes are specified in terms of indexing schemes. The basis for the determination of each index is a coordinate axis system defined by the unit cell for the particular crystal structure. 

For hexagonal unit cells, a four-index scheme for both directions and planes is found to be more convenient. Directions may be determined using Equations 3.11a-3.11d... 

Another mechanical property that may be important to consider is hardness, which is a measure of a material s resistance to localized plastic deformation (e.g., a small dent or a scratch). Early hardness tests were based on natmal minerals with a scale constructed solely on the ability of one material to scratch another that was softer. A qualitative and somewhat arbitrary hardness indexing scheme was devised, termed the Mohs scale, which ranged from 1 on the soft end for talc to 10 for diamond. Quantitative hardness techniques have been developed over the years in which a small indenter is forced into the surface of a material to be tested under controlled conditions of load and rate of application. The depth or size of the resulting indentation is measured and related to a hardness number the softer the material, the larger and deeper the indentation, and the lower the hardness index number. Measured hardnesses are only relative (rather than absolute), and care should be exercised when comparing values determined by different techniques.
