The edition of the Twelve Tables in Roman Statutes

In Roman Statutes the Twelve Tables Law have undergone a considerable shift: a considerable part of the delicts (iniuria, arbores furtim caesae and furtum) has been moved from Table VIII to Table II. It is argued that this shift, which breaks with the accepted arrangement, is unwarranted. Further, some observations are made on the edition of several rules in the Twelve Tables.

CALCIUM AND STRONTIUM MODEL AS FUNCTION OF AGE

Coefficients at the midpoints of 30-day intervals are summarized in Tables XXXVI–XXXVIII. Calcium intake and retention as a function of age were taken from Tables VI and XII, respectively, and corrected according to Appendix C. Strontium intake was derived similarly from Table XV. The procedures by which the other values in Tables XXXVI and XXXVII were computed are summarized in Table XXXIX. The growth of the infant was assumed to begin 8 days after birth. Calcium fluxes at age 8 and 16 days were estimated to be the same as those in the following 30-day interval (see Table XXXVI), except for the total retention value taken from Table XII. Strontium intakes were taken to be 420 µg per day at these ages, based on an estimated strontium/calcium ratio of 0.9 mg per gram for a diet consisting mostly of formula. These estimates enable one to compute the accumulation of calcium and strontium between birth and the ages at which data were collected. Although several sets of values are given to three digits, these are presented only for internal consistency when computing fluxes; the accuracy of the values is represented better in Figures 15 and 21. Note, for example, that values of calcium in feces in Table XXXVI differ by several milligrams per day from directly measured values in Table VIII. All values in Table XXXVIII, except the strontium intake (which is identical to values in Table XXXVII), were obtained by trial-and-error fitting of strontium-90 values in urine and feces to the measured values for 30-day intervals (see Figure 29).
