A frequency response device has been designed and built based on previous efforts by Y. Yasuda, L. C. V. Rees, F. Meunier, and Ph. Grenier. This design uses the best attributes of the three previous devices and is improved in five specific ways. First, the device makes use of the fast response capacitance manometer. Second, the device uses a servomotor to push and pull a metal bellows pump, which drives the sinusoidal input function, removing the chance of “floating” the bellows. Third, both sinusoidal and step-change volume perturbations can be studied. Fourth, the overall cost of the device was kept below $30 000. Finally, the pressure transducer is mounted only 8 cm from the sample, instead of ∼30 cm, thus removing any averaging of the pressure signal at higher frequencies. The device is currently capable of measuring frequencies between 0.005 and 5 Hz, a range of three full orders of magnitude. The system can operate at temperatures between room temperature and 473 K and pressures between 0.3 and 300 Torr. Two systems were used to test the device, n-hexane/silicalite and methanol/silicalite. The model developed by Yasuda is used to analyze the frequency response of these systems. This model can describe a system as having more than one diffusivity and accounts for the presence of a surface resistance to diffusion. The results for n-hexane/silicalite and methanol/silicalite are compared to those of van den Begin and Nayak, respectively, and are in good agreement. Also, the diffusivities measured using this device are comparable to those estimated in 1997 by Rees using the frequency response method. In addition to measuring the diffusion rate processes, the kinetic parameters associated with a surface resistance to diffusion were also estimated.

After a new reading of P.CtYBR inv. 4510, combined with a musical analysis, it is possible to detect the presence of three musical pieces, written respectively in diatonic scales of hypo-iastian, iastian and hyper-iastian. These three melodies are notably different in their composition. The first one shows a large variety of rhythmical figures, uses chromatic degrees and metaboles, when the two others seem to be written in a soberer way. In particular, the hypothesis of a new scale, created by the componer for this first piece only, is proposed here.

New readings and a rearrangement of the fragments have led to this reedition of anArsinoite bank register, first published two years ago (APF 55/2 [2009] 230-250

accès payant en janvier 2022) Christian Palestinian Aramaic 4.12.1 Manuscript Evidence and Modern EditionsChristian-Palestinian-Aramaic fragments of Ecclesiasticus are preserved of three different manuscripts. The first fragment has been published by Duensing, 1 who says that it was a piece of parchment used to repair a Syriac manuscript, but he does not give any further information about this Syriac manuscript. 2 No more information is given about the physical aspect of this CPA fragment, which contains three short passages of Ben Sira: Sir 12:17-18; 13:3-4; and 13:7. The edition and the description suggest that what was published is a strip of parchment cut along the width and that the leaf contained three columns. This would hence be the first witness to a CPA manuscript written in three columns.The second fragment is a leaf of palimpsest parchment found in Cairo Genizah (Cambridge, Univ. Library, T.-S. 12.191). It was published by Smith-Lewis and Dunlop-Gibson 3 in 1900 and reprinted by the same two years later. It gives the text of Sir 18:18-19:1. The leaf presents various lacunae, notably on the upper and on the lower parts of the right column of the recto and, thus, on the left column of the verso. Because of this, few letters or words are readable in Sir 18:18; 18:21-22; 18:31-32; and 19:1. The text was reedited by Müller-Kessler and Sokoloff, who made emendations and numerous propositions to fill the lacunae. 4 The third manuscript is a leaf cut in two parts, found in the store-room of the Great Mosque in Damaskus. The two fragments were published in 1905 by Schulthess as II 4 and II 10. 5 They belonged to a group of seven original parchment leaves, all cut in two parts, bound together, and reused for Arabic comments on the Quran. 6 The CPA text was reedited by Müller-Kessler and Sokoloff, who have filled some of the lacunae. 7 The present location of these fragments is unknown; thus, the last editors were not able to check the readings of Schulthess. It has to be noticed that the transcription of Schulthess presents an oddity: the recto side of the fragments contains together 24 lines of text, while the verso side contains 23 lines. The text though does not translate properly the Greek Vorlage on the verso side. Precisely around the cut of the two pieces, on the right column, the translation of δυνάμεως κραταιᾶς "mighty power" (Sir 46:5) is missing. On the left column, the size of the lacuna -one line only -seems too short to contain the translation of ἔναντι ἐκκλεσίας "oppose an assembly" (Sir 46:7), which
