It is difficult to identify all of the possible events and their consequences in a complex chemical processing plant without the application of systematic procedures and proper management techniques. Several hazard evaluation procedures have been developed. Most of these procedures are described in other AIChE/CCPS publications such as Guidelines for Hazard Evaluation Procedures [2,3] and Guidelinesfor Quantitative Risk Analysis [4]. Other publications on hazard evaluation techniques include [246,247]. 

Jacobsen and co-workers (61) demonstrated that diimine-copper complexes are moderately selective for the asymmetric cyclopropanation of 1,2-dihydro-naphthalene, Eq. 44. A correlation was found between selectivities in the asymmetric aziridination and the asymmetric cyclopropanation catalyzed by the same species. Jacobsen argues that this supports the notion that the two processes follow similar mechanistic pathways. These workers also studied the complexation event between alkenes and Cu(I)-diimine complexes by NMR and by crystallographic characterization (62). For a thorough treatment of these results, see Section II.B.3. 

When available, fundamental process models are preferred. For many complex processes such as composite manufacturing in general and autoclave curing in particular, however, these models are often not available. This lack of availability is due to an inadequate understanding of the complex events that take place during the process. A fundamental process model is occasionally available, but it is still unsuitable for on-line model predictive control application due to the extensive computing time required to solve the model s equations. This lack of... 

Vibrational microspectroscopy provides a unique means for molecular level structure characterization of a variety of biological processes associated with skin. For the past several years, this laboratory has utilized Raman and IR spectroscopy, microscopy, and imaging to monitor the biophysics of the skin barrier, mechanisms of drug permeation and metabolism in intact tissue, and, more recently, the complex events that transpire during wound healing in an ex vivo skin model [1-6]. 

It is well established today that drug absorption through the alimentary canal walls is a complex event, which involves, in many cases, parallel or sequent microprocesses at the apical membrane of the absorptive cell (enterocyte) or between them (paracellular absorption). In addition to the various types of diffusion processes across the enterocyte membrane, numerous specific proteins—transporters and efflux pumps—are involved in the intricate drug absorption process. In the following sections the various epithelial tissues of the different organs of the GI tract will be looked at briefly. A review of major drug absorption mechanisms across epithelial cells, as they are customary today will follow. 

For example, some people think in images, others in words. Some can voluntarily anesthetize parts of their body, most cannot. Some recall past events by imaging the scene and looking at the relevant details others use complex verbal processes with no images. 

The atherosclerotic lesions develop in a complex, chronic process. The first detectable lesion is the so-called fatty streak, an aggregation of lipid-laden macrophage foam cells. The next stage of development is the formation of plaques consisting of a core of lipid and necrotic cell debris covered by a layer of connective tissue and smooth muscle cells. These plaques hinder arterial blood flow and may precipitate clinical events by plaque rupture and thrombus formation. Platelets from the thrombi, activated macrophages, and smooth muscle cells release growth factors and cytokines resulting in an inflammatory-fibroproliferative response that leads to the advanced lesions of atherosclerosis. 

The photophysical effects and mechanisms described in general terms in the above sections will now be illustrated with the aid of findings and interpretations from the world of dendrimers. Since straightforward luminescence effects are also mentioned elsewhere in this book in the context of syntheses (Chapter 2) and the individual types of compounds (Chapter 4) and are, moreover, considered as part of more complex events in Section 5.2, just a few characteristic examples of fluorescence and phosphorescence of dendrimers will be presented The adjacency of many groups in a molecule may lead to the occurrence of complex processes, which sometimes make it difficult to draw precise conclusions, but may sometimes also be useful and amenable to optimisation for various applications. 

The Genomic Potential Hypothesis develops the evolutionary events as a consequence of chemical/biochemical principles. Even complex biochemical processes such as thought and emotion fall under the purview of science and perusal of contemporary science literature supports that statement. 

In this report, chemical imaging is defined as the spatial and temporal characterization of the molecular composition, structure, and dynamics of any given sample—with the ultimate goal being able to both understand and control complex chemical processes. As illustrated by the case studies in Chapter 2, this ability to image or visualize chemical events in space and time is essential to the future development of many fields of science. 

Despite origination of interrelated reactions in the early 1900s, the outlook for chemical interference is expected to be, if not extraordinary, but quite useful for interpretation of complex events and voluntary control of processes proceeding in chemical and biological systems. 

The characteristics of membrane permeation are partition, including affinity, location, specific interaction with certain phospholipids, and diffusion kinetics. Because of the complex events involved during drug absorption in vivo, true membrane permeability modeling cannot always be expected. Therefore, many attempts have been made to develop suitable in vitro systems to study the permeation process and its dependence on membrane composition and drag physicochemical properties.
