Investigation Summary

The accident investigation report is the major result of the investigation. In general, the format should be flexible and designed specifically to best explain the accident. The format may include the following sections (1) introduction, (2) process description (equipment and chemistry), (3) incident description, (4) investigation results, (5) discussion, (6) conclusions, and (7) layered recommendations. 

The accident investigation report is written using the principles of technical documentation. Items 1-4 are objective and should not include the authors opinions. Items 5-7 appropriately contain the opinions of the authors (investigation team). This technical style allows readers to develop their own independent conclusions and recommendations. As a result of these criteria, the accident investigation report is a learning tool, which is the major purpose of the investigation. 

The previously described accident investigation report is a logical and necessary result of an investigation. It includes comprehensive details that are of particular interest to specialists. These details, however, are too focused for an average inquirer.

The District of Columbia staff was initially troubled by the allegation of a burial in the 1930s because it ran contrary to the assumption based on some evidence that any burials that did occur happened prior to 1922. Therefore, the District raised the issues presented in the phone call memorandum at the regular May 1998 work group meeting in Baltimore. The Corps provided a copy of its thorough investigation summary and added that they spoke with Noel s widow, who stated that Noel was nevo" in the CCC.

In summary, for the most active of catalysts, the copper(II) ion, the diamine ligands that were investigated seriously hamper catalysis mainly by decreasing the efficiency of coordination of the dienophile. With exception of the somewhat deviant behaviour of N,N -dimethylethylenediamine, this conclusion also applies to catalysis by Ni" ions. Hence, significant ligand-accelerated catalysis using the diamine ligands appears not to be feasible. 

In summary, the groups of Espenson and Loh observe catalysis of Diels-Alder reactions involving monodentate reactants by Lewis acids in water. If their observations reflect Lewis-acid catalysis, involvirg coordination and concomitant activation of the dienophile, we would conclude that Lewis-acid catalysis in water need not suffer from a limitation to chelating reactants. This conclusion contradicts our observations which have invariably stressed the importance of a chelating potential of the dienophile. Hence it was decided to investigate the effect of indium trichloride and methylrhenium trioxide under homogeneous conditions. 

Because of the extreme difficulty in handling fluorine, reported physical properties (Table 1) show greater than normal variations among investigators. A detailed summary and correlation of the physical, thermodynamic, transport, and electromagnetic properties of fluorine is given in Reference 20.

Three new papers bearing on the structure of strychnine have become available too late for inclusion in this summary of recent work. Woodward, Brehm and Nelson have compared the ultra-violet absorption spectra of strychnine and Leuchs s strychnone (p.. 559) and used the results for a discussion of the relationship of the two alkaloids. Prelog and Kathriner have investigated the oxidation of strychnine, i/t-strychnine and brucine by permanganate in weakly acid solution and Bailey and Robinson from a study of the brucones have confirmed the conclusion of Woodward et al. that Leuchs s strychnone is a true indole derivative. Mention must also be made of a paper by Clemo and King on new reduction products of strychnine, of which a preliminary account has been published with a summary of the ensuing discussion. 

The stereochemistry of the 1,4-addition to A -octal-l-one and 1,1-di-methyl-A -octal-2-one has been investigated by House and Marshall, respectively. In summary, steric and stereoelectronic factors play a part in the mechanism of conjugate addition of Grignard compounds. With methylmagnesium iodide, the introduction of an axial methyl group into steroidal 5a-A -3-ketones (3) and 5 -A -3-ketones (6) is favored by stereo-electronic factors in the transition state.

It seems quite obvious that the thiophenes are related to the polyacetylenes which they accompany. This viewpoint has recently been illustrated by the formation of thiophenes from polyacetylenes and hydrogen sulfide under almost biological conditions. In a recent lecture summary, the preparation of terthienyl, junipal, and (241) from 1,4-disubstituted butadiynes and hydrogen sulfide is claimed. A large number of bithienyls have been prepared and their nemato-dicidal activity investigated. All the compounds with strong activity were found to be derivatives of 2,2 -bithienyl. ... 

The tautoraerism of certain difunctional derivatives of l-thia-3,4-diazole has received considerable attention. Pala assigned structure 156 to 2,5-dimercapto-l-thia-3,4-diazole on the basis of infrared spectral data, and Thorn" reached the same conclusion by comparing its ultraviolet spectrum (measured in ethanol) with those of the four possible methylated derivatives. However, the infrared spectrum of a chloroform solution of the parent compound showed bands at 2600-2550 cm indicating an SH group and the probable occurrence of form 157 under these conditions, and this conclusion is supported by the occurrence of SH bands in solid state spectra obtained by Swiss investigators. For a summary of earlier work on these compounds, see reference 187.

Many investigators have studied the anodic behaviour of nickel. A complete discussion of the reactions occurring during anodic dissolution and passivation of the metal is outside the scope of this chapter, which is confined to a brief summary of the main features of practical significance.
