Virtually all of this development and improvement of Volume 2, especially in the much expanded Chapters 10 and 12, is thanks to the thorough and painstaking work of Terry Baldwinson, who has carefully sifted through an extensive yet scattered range of primary sources. Our grateful thanks are due to John Holmes and Catherine Whitehouse for their patient copy editing and to the publications staff of the Society, especially Carol Davies, who have prepared all the material in this new edition for publication. 

Spectrometer ARL 3400 C Quantovac 1 m Paschen-Range monuing grating ruled 1080 lines mm"1, 0.309 nm mm-1 reciprocal linear dispersion (3rd order). Primary slit width 20 pm, secondary slit 50 pm, Hamamatsu R-306 photomultiplier tube... 

They used a vertical cylindrical pot furnace of batch type, like Rogers. Two conversion concepts were simulated (a) overfired, updraft, fixed horizontal grate, and batch reactor and (b) underfired, updraft, fixed horizontal grate, and batch reactor. The diameter was 178 mm and primary air was supplied under the grate (Figure 7). A mirror was placed above the overbed section to be able to observe the combustion behaviour. 

Thermocouples were placed inside the fuel bed, to be able to follow the temperature history, which contained a great deal of information about the thermochemical processes occurring in the bed. The sample ports were positioned at 45, 145 and 245 mm above the grate. These ports could also be used for gas sample probes. The primary air could be preheated up to 200°C and the air flow rate could be varied between 150-1500 1/min. 

Heat fluxes (grate loadings) on 1500 kW/m can be obtained by cocurrent combustion, but for wet biofuels the heat fluxes are only 500 kW/m. Wood chips with a moisture content of 40% are very hard to bum in a cocurrent configuration. On the other hand, if a countercurrent configuration is used between fuel feed and primary air flow it is possible to bum very wet fuels upto 55-60%. Heat fluxes on 1 500 kW/m can be attained for wood chips with a moisture content of 40%, if the air flow velocity is 0.1 m/s. 

Primary air (underfire air) supplied through the grate and secondary air (overfire air) was supplied between section C and D through eight radial tubes with small nozzles. The secondary air jets were introduced normal to the vertical flow of over-bed combustion gases. 

Primary fundings for these investigations were provided by the American Water Works Research Foundation and U.S. Environmental Protection Agency. The work was supported by the U.S. Department of Energy, Division of Environmental and Biomedical Research. The co-operation and advice of James S. Fritz, Harry J. Svec, Ron Webb, O. Thomas Love, Michael Taras and the various representatives of the fourteen water utilities are gratefully acknowledged. 

Eventually, cis-l,2-di-9-anthrylethylene was prepared, as originally planned, by catalytic hydrogenation of bis-9-anthrylacetylene 53 [148]. Also, thanks to the appearance of a suitable oxidant for the conversion of primary and secondary alcohols into aldehydes and ketones [149], the synthesis of l,2-di-9-anthrylethanol 127 has been accomplished [51]. Numerous other chromophorically substituted anthracenes discussed in Sections II and III then became available as a matter of consequence. In retrospect, I feel gratefully indebted not only to my co-workers for their collaboration, but also to those numerous authors from whose earlier published efforts in the area of anthracene chemistry we have benefitted in our photochemical... 

The phenomenological description of signal generation in TDFRS is, in principle, straightforward [27,28,33,44,45]. The primary source of excitation is the optical interference grating formed by the two writing beams, which intersect under an angel 6 inside the sample ... 

Now, the effective linear response function h(t) can be identified with g(t) as defined in Eqs. (25) and (29) h(t) = g(t). The primary sample response is the heterodyne diffraction efficiencyy (t) = Chet(t)- The instantaneous contribution of the temperature grating to the diffraction efficiency is expressed by the 5-function in g(t) [Eq. (25)]. After the sample, an unavoidable noise term e(t) is added. The continuous yff) is sampled by integrating with an ideal detector over time intervals At to finally obtain the time-discrete sequence y[n]. 

The text has been substantially revised, many new examples incorporated and errors corrected. A substantial new chapter dealing with supramolecular chemistry has been incorporated. Once again, a deliberate decision was made to try to limit references to the secondary rather than the primary literature. Where structural data have been presented, the use of the files of the Cambridge Crystallographic Data Centre and the Brookhaven Protein Structure Data Base are gratefully acknowledged. 

The data collected and shown are from secondary sources—where they have previously been critically evaluated and selected—whenever warranted, but more recent primary sources in research journals have been used to supplement the former or to supersede them if deemed necessary. Access to the primary sources has been through the abstracts up to 1996. The selection of the solvents for which the data are included in this book (the List) is discussed in the Introduction. I am solely responsible for such choices, regarding solvents and data, as have been made. I will be grateful for indications of errors, oversights, and further useful data that may be brought to my attention. Some of the tables are confined to those solvents from the List for which the relevant data have been reported. However, for most of the more extensive tables, many blank spaces have been left, and in some cases entire rows of data have been left blank. This was done with the hope of calling attention to the lack of reliable data, and the expectation that some of these blanks may be filled within the useful lifetime of this book (and its author).
