Perfect order focus

Crystals are distinguished by the regular, periodic order of their components. In the following we will focus much attention on this order. However, this should not lead to the impression of a perfect order. Real crystals contain numerous faults, their number increasing with temperature. Atoms can be missing or misplaced, and dislocations and other imperfections can occur. These faults can have an enormous influence on the properties of a material. 

By using a measure like total perfect orders to evaluate the performance of suppliers, you are able to get a complete picture of their performance. Most suppliers get most of the criteria right for an order, but the focus needs to be on getting all seven of the criteria right. Performance like this is what it is going to take to remain competitive in the global market. 

Once a free carrier has been created, we then encounter a further class of fascinating transport phenomena associated with the low dimensionality of the system and this is where we want now to focus our attention upon. Let us first consider the diffusion of carriers along a one-dimensional chain. A realistic view of the polymer backbone in PDA is of course not one of perfect order but every now and again we must expect a defect which leads to the formation of a trap (or anti-trap) with probability s [5]. In addition, carriers will also eventually reach recombination centres which lead to the total annihilation of the charge [6]. Depending on the time temperature domain, an ordinary trap may be indistinguishable from a recombination centre. We therefore... 

The primary objective of preprocessing treatments is to remove the nonchemical biases from the spectral information. Scattering effects induced by particle size or surface roughness may lead to offsets or other more complex baseline distortions. Differences in sample density or the angle of presentation may induce overall intensity variations as well as additional baseline distortions. Most samples are not perfectly uniform on the microscopic scale, and these effects may dominate the initial contrast observed in an un-processed chemical image. In some cases this contrast may provide useful information to the analyst however, it is generally removed in order to focus on the chemical information. 

Spin-Spin Coupling Although we focus on spin-orbit coupling (SOC), we need to consider the tensorial structure of electronic spin-spin coupling Second-order SOC mimics perfectly first-order spin-spin coupling and vice versa, so that they cannot be told apart (see the later section on second-order spin-orbit splitting). 

We remark that memory function methods have been extensively applied to perfect crystals, where they are alternative tools to the traditional band structure methods. In the presence of translational symmetry and long-range order, however, the use of the memory function techniques is not essential but rather a matter of convenience (or taste) in a number of situations. We thus focus on the study of the electronic structure in systems that are aperiodic because of impurities our unorthodox way of looking at defects is to consider them as a source of a given frozen-in disorder in an otherwise perfect crystal lattice. The more general case of the presence of stochastic disorder will be discussed in Section VI.
