Bases, Sources, and Studies

This chapter provides summaries of seleeted data resourees available to the CPQRA praetitioner. These resourees are summarized in a eonsistent format that allows them to be easily reviewed and eompared. Those resources whieh are available to CCPS and contain equipment failure rate data of suffieient quality are used for the data tables in Seetion 5.5. 

Seetion 4.1 deseribes how data resourees were ehosen for inelusion in this book. Section 4.2 describes the format used to present the information on the data resources, and Sections 4.3 through 4.8 present these data resources. Eaeh resouree section is preceded by an index of the resources presented in the section.

Chapter 4—Data Bases, Sources, and Studies Summarizes and characterizes several generic data resources available to risk analysts and process engineers in the CPI. It includes a discussion of the resource search and selection process and the presentation format for the information on resources. 

Appendix D—Unreviewed Data Bases, Data Sources, and Studies Provides a list of data resources that were uncovered too late for review.

Alternative feedstocks for petrochemicals have been the subject of much research and study over the past several decades, but have not yet become economically attractive. Chemical producers are expected to continue to use fossil fuels for energy and feedstock needs for the next 75 years. The most promising sources which have received the most attention include coal, tar sands, oil shale, and biomass. Near-term advances ia coal-gasification technology offer the greatest potential to replace oil- and gas-based feedstocks ia selected appHcations (10) (see Feedstocks, coal chemicals). 

Numerical simulation of hood performance is complex, and results depend on hood design, flow restriction by surrounding surfaces, source strength, and other boundary conditions. Thus, most currently used method.s of hood design are based on experimental studies and analytical models. According to these models, the exhaust airflow rate is calculated based on the desired capture velocity at a particular location in front of the hood. It is easier... 

Concerns over atmospheric methane as a greenhouse gas and the large contribution of biomethanogenesis as a source of this gas make it important to determine the relative significance of various components of this activity. A recent paper (8) summarized estimates (28-30) of source fluxes of atmospheric methane based on several carbon isotopic studies and presented new data on natural sources and biomass burning. These data (Table III) show that of a total flux of 594 million tons (Tg) per year, 83% is produced via biomethanogenesis from a combination of natural (42%) and anthropogenic (41%) sources. 

The diet of the 19 century residents of Upper Canada was determined from historical sources and was reproduced in order to carry out chemical analysis. Stable carbon isotope analysis of food and human bone demonstrates that the spacing between the food eaten and the bone collagen is around 5.6%o. The value may vary slightly from this estimate since the latter is based on a reconstructed diet and a large number of bone samples, which exhibit a small amount of variation. Nevertheless, this empirically derived result agrees well with estimates from field (Vogel 1978), and laboratory studies (reviewed in Ambrose 1993).

The remarkable processes of life and decay are based on the ability of enzyme systems to function in a dual role in the dynamic metabolism associated with living systems. On the one hand, the enzymes present in organisms promote the synthesis of complex organic compounds from low molecular weight intermediates, and, on the other hand and simultaneously, other enzymes present therein facilitate the degradation of such compounds. Thus, in the study of the source and ultimate fate of a natural substance in living cells, the investigation of both the pathway of its synthesis and its breakdown are of equal importance. 

Summary. This Chapter focuses on the investigation of fast electron transport studies in solids irradiated at relativistic laser intensities. Experimental techniques based upon space-resolved spectroscopy are presented in view of their application to both ultrashort Ka X-ray sources and fast ignition studies. Spectroscopy based upon single-photon detection is unveiled as a complementary diagnostic technique, alternative to well established techniques based upon bent crystals. Application of this technique to the study of X-ray fluorescence emission from fast electron propagation in multilayer targets is reported and explored as an example case.
