In 1953, he received an offer from the University of Pennsylvania, one of the oldest and most distinguished universities in the United States, which was also located in a major center of chemical industries. In 1954, he accepted the position as the Benjamin Franklin Professor of Chemistry and chairman of the Chemistry Department. In the transitional summer of 1954, he gave a series of lectures on polymer chemistry at the Brooklyn Polytechnic Institute, which became the basis of his first book, Reactions at the Carbon-Carbon Double Bond. An important original idea posited in this book was the phenomenon of pi-bonding. From the beginning of his doctoral research at Harvard, a major common thread to many of Charles contributions was his keen interest in the detailed mechanisms by which chemical reactions occur.

Pipe dope Pipe connections require the use of pipe dope. American Petroleum Institute (API) specified pipe dope contains about 30% lead by weight and, therefore, can be of concern when disposed of. One simple waste minimization technique is to ensure that all pipe dope is used and containers are completely empty. However, lead-free, biodegradable pipe dopes are now available and, if feasible, should be substituted for API specified pipe dope. Even if API specified pipe dope is necessary for making the required connections, pipe supply companies should be asked to provide pipe with lead-free pipe dope on the thread protectors. 

Figure 5.8 Cross-sectional TEM images of GaN films on (a) nonporous SiC substrate, and (b)-(d) on porous SiC substrates. The label ps denotes a porous substrate and np denotes a nonporous substrate. The surface pore density of the substrate in (b) is 13 prrr2, and in (c) and (d) is 11.5 pm-2. The open tubes in the GaN films on porous substrates are marked by T (the tubes appear white in contrast near the top of the film where they are empty, and black near the interface where they are filled by Ga). The regions labeled D contain a relatively low number of threading dislocations originating at the interface (due to the lateral epitaxial growth over the substrate pores), and they contain dislocation half-loops gliding in from tubes. One half-loop is faintly seen to the right of a in (c). Reproduced from A. Sagar et al., J. Vac. Sci. Technol. B 21, 1812. Copyright (2003), with permission from the American Institute of Physics...

Figure 8.13 Plan-view transmission electron micrograph of GaN grown on a TiN interlayer [16]. Screw- or mixed-type threading dislocations (s) exhibit a characteristic black/white image contrast aligned with the scattering vector (g). Contrast from edge dislocations (e) is much weaker.

Nevertheless, these things said, there are examples here and there of cures, or at least remissions. Thus, there is Elaine Nussbaum s Recovery from Cancer A Personal Story of Sickness and Health, published in 1997. And there is the organization called Institute for Noetic Sciences in Sausalito, California, that keeps track of such cases ( noetic, pertaining to the mind). It would be extremely informative to determine if there is any sort of a common thread that links these recoveries.

The themes of witchcraft and mental illness, the Inquisition and Institutional Psychiatry, form two distinct threads which may be pulled from the tapestry of Western man s cultural history and examined separately. This is what I have tried to do in this volume. To place the events and ideas here examined in their historical context, and to provide the reader with a sweeping, though fragmentary, view of the whole fabric from which these threads have been tom, I have assembled, in this Appendix, a synoptic history of the dates, events, men, and opinions that seemed to me illustrative of, and significant in, the unfolding of this aspect of our history. 

The initial aluminum FSW studies conducted at The Welding Institute (TWI) used a cylindrical threaded pin and concave shoulder tool machined from tool steel (Ref 2). Since that time, tools have advanced to complex asymmetric geometries and exotic tool materials to friction stir higher-temperature materials. This...

Tables 9.9((a) through (c)), which follow, sununarize Chlorine Institute recommendations. They are taken from Tables 4-1 through 4—7 of Pamphlet 6. Certain threaded valves are permitted in small sizes. Except for connections to transport equipment, instruments, and special process equipment, flanged valves are preferred in piping classes II, III, V, and VI. In the tables, S denotes satisfactory service, NR denotes not recommended, and a dash denotes the lack of sufficient experience to support classification (as of December 1998).

The Cetex Institut fur Textil- und Verarbeitungsmaschinen gemeinniitzige GmbH based in Chemnitz, Germany, has been developing new areas of application for the 3D contour warp knitting process oti double-bar Raschel machines since 1997. The objective, to enable the incorporation of directly oriented thread systems into the base fabric (filler thread, weft thread), was reached (Anmi., 1997b). 

The (Cl)-5 thread is applicable to ton container valves and fuse plugs however, to avoid interfering with the eductor tube weld attachment, a very short lead must be used on the tap for a (Cl)-5 ton container valve thread. Chlorine Institute Pamphlet 17 does not recommend use of (Cl)-5 threads in chlorine cylinders [3].
