In the manuscripts of Epitoma rei militaris, we can find in the presentation of the work the following words: "[...] The Compendium of Military Art by Flavius Vegetius Renato uir ilustris comes, in number of four books, starts at a happy hour (7)" (Epitoma rei militaris, I, Pref.).
2: Word-initial h, which in post-classical verse could lengthen a nominally short final syllable that ended in a consonant (e.g., niger hispidus but uir humilis).
Ulcer inhibition ratio (U1R) was calculated as follows: UIR = ([U.sub.m] - [U.sub.t])/[U.sub.m] x 100%.
If a uniform impedance resonator (UIR) is used to replace [TSSIR.sub.b] to simplify the design and analysis of the TBBSF, the necessary condition of [Z.sub.3b] = [Z.sub.3a] always results in single value of [Z.sub.3b].
Figure 3(b) shows that when [Z.sub.1] and [Z.sub.2] are equal the characteristic impedance of the resonator is uniform and accordingly a uniform impedance resonator (UIR) is obtained.
