Much of the work reported in the literature on cellulose acetate reverse osmosis membranes has raised new and important questions with regard to the dense or “active” layer of these membranes. Several thickness values and structures have been attributed to the dense layer. To ensure the correct interpretation of the cellulose acetate structure thirteen different preparative techniques have been used in this investigation. These thirteen methods included various combinations of water substitution, freeze drying, freeze sectioning, fracturing, embedding, and microtomy techniques with both transmission and scanning electron microscope observations.It was observed that several factors can cause a distortion of the structure during sample preparation. The most obvious problem of water removal can cause swelling, shrinking, and folds. Improper removal of embedding materials, when used, can cause a loss of electron image contrast and, or structure which could hinder interpretation.

Image Simulations

For well over two decades computers have played an important role in electron microscopy; they now pervade the whole field - as indeed they do in so many other aspects of our lives. The initial use of computers was mainly for large (as it seemed then) off-line calculations for image simulations; for example, of dislocation images.Image simulation has continued to be one of the most notable uses of computers particularly since it is essential to the correct interpretation of high resolution images. In microanalysis, too, the computer has had a rather high profile. In this case because it has been a necessary part of the equipment delivered by manufacturers. By contrast the use of computers for electron diffraction analysis has been slow to prominence. This is not to say that there has been no activity, quite the contrary; however it has not had such a great impact on the field.

Inverse Coefficient

An inverse coefficient problem is considered for time-fractional anomalous diffusion equations with the Riemann-Liouville and Caputo fractional derivatives. A numerical algorithm is proposed for identification of anomalous diffusivity which is considered as a function of concentration. The algorithm is based on transformation of inverse coefficient problem to extremum problem for the residual functional. The steepest descent method is used for numerical solving of this extremum problem. Necessary expressions for calculating gradient of residual functional are presented. The efficiency of the proposed algorithm is illustrated by several test examples.

Scholars have barely begun to explore the role of the Old Testament in the history of the Spanish New World. And yet this text was central for the Empire’s legal thought, playing a role in its legislation, adjudication, and understandings of group status. Institutions like the Council of the Indies, the Inquisition, and the monarchy itself invited countless parallels to ancient Hebrew justice. Scripture influenced how subjects understood and valued imperial space as well as theories about Paradise or King Solomon’s mines of Ophir. Scripture shaped debates about the nature of the New World past, the legitimacy of the conquest, and the questions of mining, taxation, and other major issues. In the world of privilege and status, conquerors and pessimists could depict the New World and its peoples as the antithesis of Israel and the Israelites, while activists, patriots, and women flipped the script with aplomb. In the readings of Indians, American-born Spaniards, nuns, and others, the correct interpretation of the Old Testament justified a new social order where these groups’ supposed demerits were in reality their virtues. Indeed, vassals and royal officials’ interpretations of the Old Testament are as diverse as the Spanish Empire itself. Scripture even outlasted the Empire. As republicans defeated royalists in the nineteenth century, divergent readings of the book, variously supporting the Israelite monarchy or the Hebrew republic, had their day on the battlefield itself.

The study of graphic communication techniques that engineers, architects, and designers use to express ideas and concepts, or the graphic expression applied to the design process, is becoming increasingly important. The correct interpretation of graphic language allows the development of skills in the training of an engineer or architect. For this reason, research on this topic is especially valuable in finding improvements or new proposals that help toward a better understanding of those techniques. This Special Issue shows the reader some examples of different disciplines available, such as engineering graphics, industrial design, geometric modeling, computer-aided design, descriptive geometry, architectural graphics and computer animation.
