Summary of Major Points

Estimated Exposures (pg/kg/day) to the General Population Based on Extrapolated Intake from Urinary Metabolites in 289 Individuals Measured by Blount et al. (2000), 170 5-6 Properties of Biomarkers Used as Examples in Chapter 5, 188 7-1 Summary of Major Points in Research Agenda, 252...

Tricyclics interact with other drugs and substances at a variety of points during distribution and metabolism. Most interactions occur at the CYP isoenzyme complex in the liver. Other interactions occur at peripheral sites and involve interaction at the noradernergic receptors (a and P). A summary of major TCA drug interactions is given in Table 23.2. 

Figure 10.4. A summary of major human P450s involved in drug metabolism, including major substrates, inhibitors, and inducers (adapted from Breimer) - The sizes of the circles indicate the approximate mean percentages of the total hepatic P450 attributed to each P450 (See also Figure 10.1 and Table 10.5). The overlap of the circles is to make the point that overlap of catalytic action is often observed, although the overlap does not necessarily refer to the indicated substrates (or inhibitors).

Our understanding of how the events preceding a disaster unfold has been greatly expanded in the last 20 years by the careful examination of a number of high profile accidents (Boxes 7.1 and 7.2). The brief summaries of major accidents, and the account of the Columbia Space Shuttle accident, allow us to reflect on the many ways in which failure can occur and the complexity of the story that may unfold during a serious investigation. Human beings have the opportunity to contribute to an accident at many different points in the... 

The summary of the bulk chemical compositions (major elements, minor elements, rare earth elements), Sr/ Sr (Farrell et al., 1978 Farrell and Holland, 1983), microscopic observation, and chemistry of spinel of unaltered basalt clarifies the tectonic setting of Kuroko deposits. Based on the geochemical data on the selected basalt samples which suffered very weak alteration, it can be pointed out that the basalt that erupted almost contemporaneously with the Kuroko mineralization was BABB (back-arc basin basalt) with geochemical features of which are intermediate between Island arc tholeiite and N-type MORE. This clearly supports the theory that Kuroko deposits formed at back-arc basin at middle Miocene age. 

The first part of Chapter II is tutorial in nature and lays the background thought to be necessary for the discussion and analysis in the latter chapters. The material on non-equilibrium effects included in this chapter and Chapter IH is perhaps one of the more complete coverages of this subject to be presented in a book. The performance of chemical propellants is then analyzed in the last two chapters. In particular, the authors hope that the readers will find the Postface a useful and stimulating summary of most of the major points made throughout the text. 

The human-related sources of mercury to the environment are numerous and widespread. Most direct inputs of mercury from point sources to aquatic systems have largely been contained in most developed countries. Inputs of mercury to the environment via the atmosphere are of the greatest concern. These emissions, coupled with long-distance transport of elemental mercury, have resulted in elevated concentrations of mercury in fish from locations that are removed from anthropogenic sources (e.g., open-ocean, and semi-remote regions in the United States, Canada, Scandinavia Wiener et al., 2002). A summary of the fluxes from major sources (for 1995) is shown... 

In the following, we provide a summary of the most important kinds of defects at the MgO surface (Table2.1). In a broad classification, one can recognize at least 12 major kinds of point defects ... 

As already pointed out, the majority of the pertinent literature is in Chinese while the rare contributions in English are not at all detailed. Therefore, we have included in the next subsection (5.2.6) a summary of modem Chinese APT technology written by an expert from China. 

The following is a summary of some of the major points of PEGylation chemistry of biological macromolecules. 

Table 9 shows the summary of the present status of ozone sensing[6]. From the view point of global environment, a major need for ozone sensing lies in the measurement of ozone concentration in high altitude of atmosphere. Especially, small and light sensors which can be mounted on a sonde or a rocket are desired. Liquid electrolyte sensors are being used now for such... 

To illustrate the point that popular books on chemistry are rare, we analysed the Guide to Popular Science Books (Rennison, 2000), which consists of titles and summaries of content of popular science books as sold by Waterstones, the major UK bookshop chain. We found that the number of books that have an overtly chemical theme was under 4% of the total. The balance of chemistry to other disciplines reflected in this analysis is echoed by displays on the shelves of Popular Science in most bookshops. A quick check at any shop will confirm that chemistry is under-represented. Even in Singapore, that most technological of societies, a major bookshop features 27 shelves of popular physics, another 29 of astronomy and just one of chemistry.
