Rate coefficients have been determined for protodeboronation of benzene- and thiophene-boronic acids in a range of aqueous perchloric acid mixtures at temperatures between 25 and 90 °C630. First-order rate coefficients are given in Table 204, but not all of the rates were measured at the acidities indicated (see Table footnote), but were corrected to these making use of the linear relationship which was found, in preliminary experiments, to exist between log rate and H0. Similarly, the relative reactivities to thiophene-2-, thiophene-3-, and benzene-boronic acid (8.5 x 10s, 7.1 x 103, and 1.0, respectively) were obtained at an H0... [Pg.301]

The previously described reactivity data for the five-membered heterocycles are gathered (in terms of o+ values) in Table 6.12 no data are given for nitration because the rates are encounter controlled and meaningless in terms of electronic effects. Among the other data, those for mercuriation, protiodemercuriation, and protiodeboronation are doubtful, and other qualifying aspects are noted in the table footnotes. The following main features are noteworthy. [Pg.129]

Give every formal table a brief, informative title that describes its contents in nonsentence format. The title should be complete enough to be understood without referring to the text. Place details in table footnotes, not in the title. [Pg.371]

Define nonstandard abbreviations in table footnotes. Name the variable being measured, and indicate the unit of measure after a comma or slash or within enclosing marks. Use the same style within and among all tables. [Pg.371]

Try to keep all entries at similar lengths by placing any explanatory material in table footnotes. If you use a dash as a column entry, explain it in a footnote the first time it is used (e.g., —, too low to be measured ). [Pg.372]

Table footnotes include explanatory material referring to the whole table and to specific entries. Examples of information that should be placed in general footnotes referring to the whole table are the following units of measure that apply to all entries in the table, explanations of abbreviations and symbols used frequently throughout the table, details of experimental conditions if not already described in the text or if different from the text, general sources of data, and other literature citations. [Pg.373]

Tables 4 and 5 summarize performance results for two different starting points. The first (xl) is closer to a minimum than the second (x2) and has lower function value and gradient norm by about four orders of magnitude (see table footnotes for details). From both starting points, we first note how well preconditioning works in TN. The residual truncation criterion of [54] and [55] was used here with cr = 0.5. With preconditioning, the number of inner (PCG) iterations is reduced by two to three orders of magnitude. Even the number of Newton iterations is reduced, and the time is accelerated by a factor of 2 to 3. Not only is precision of the resulting gradient norm not sacrificed it improves. This is a typical observation with good preconditioning. Tables 4 and 5 summarize performance results for two different starting points.

In these calculations the total volume of monomer was constant (300 cm /dm water) and the specific surface area of SDS on the monomer was set to 50 A per molecule. The other parameters arc given in the table footnote. It appears that absorption of emulsifier on the monomer droplets surface starts to become significant at droplet radii S/rm. With S — 2 g/dm HjO one passes the CMC for the emulsifier at a droplet diameter of about 1.5 foa, with 5 g S the corresponding value is 0.2/im. With droplets below that size one should expect that the droplets may become the important loci for particle nudeation. [Pg.89]

Make sure that all of the columns are really necessary. If there are no entries in most of a column, it probably should be deleted and replaced with a general table footnote. Or, if the entries in the entire column are the same, the column should be replaced with a table footnote that says In all cases, the value was x or whatever is appropriate. [Pg.156]

Every column must have a heading that describes the material below it. Be as succinct as possible, keep headings to two lines if possible, and use abbreviations and symbols whenever practical. Be consistent with the text and with other column headings. Define nonstandard abbreviations in table footnotes. Name the variable being measured and indicate the unit of measure after a comma, after a slash, or within enclosing marks. Use the same style within and among all tables. A unit of measure alone is not an acceptable column heading. A unit of measure under a straddle rule, as in Table 1, is acceptable. [Pg.390]

If a column heading applies to more than one column, use a rule below it that spans the columns to which it applies this is called a straddle rule. Below the rule, give the specific headings for each column. A column heading should not apply to the entire table information that describes all of the columns belongs in a general table footnote. [Pg.390]

In the first step, develop the partial derivative into a Jacobian determinant. Then lookup in Table 1.4 both numerator and denominator and insert the abbreviation. In the final step, from the table footnotes again expand the abbreviation into a Jacobian determinant. [Pg.49]

The second and third i iconfiguratioils are described in Figs 1 and 2 (all dimensions iii metres). Earthen materials were centered inside and placed outside the nested tanks as described tn Table L Three cases lire included where other fissile materials (table footnotes g and h) contact the tank array. These simulate interaction situations as might occur in a production facility. The resulting critical heights for the% two configurations are also reported.in Table L... [Pg.733]

The similarities and differences between iron-NO and iron-oxygen bonding have been the subjects of debate, and model compounds provide important correlations between structure, spectroscopy, and redox chemistry of iron nitrosyls. The nitrosyl groups in these complexes can be described as NO S = 0), NO S = 1/2), NO S = 0), NO (S = 1), and NO S = 1/2). The associated iron ions have charges and spins such that the overall numbers of iron d electrons plus NO Jt electrons are 6-8 in most experimentally accessible model compounds. The notation for these complexes follows the Enemark and Feltham conventions [51]. The EPR visible complexes are d , or (Fe-NO) , and d , or (Fe-(NO)2). Both S = 3/2 and S = 1/2 d complexes are found. Table 2 summarizes possible electronic states that might be considered for d iron-nitrosyl complexes. Representative references to those electronic states that are experimentally observed, or calculated, are given in the table footnotes. [Pg.255]
