This article presents a previously unpublished altarpiece depicting the Glory of Saint Francis of Paola, preserved at the side-altar a pars Evangelii in the nave of the Church of the Holy Trinity in Cepic (Cepich), a small village in the Arsa Valley in Croatia. The painting, together with the altar, must have been part of the 18(th) century furnishings of the church which was first documented in 1606 and reconstructed to its present form in 1872. Dating back to the 18th century are also the high altar (1779) which was erected at the time of the parish priest Nicolo Grabrich and which in its mensa still retains part of a tombstone from 1715 and the other side-altar, erected by the parish priest Ancich at his own expense (1707). The Glory of Saint Francis of Paola displays unequivocal stylistic and compositional similarities with the Gorizia works attributed to Francesco Pavona (1692-1773). For exemplifying purposes, an altarpiece depicting Saint Nicholas, Anthony the Great and Saint Florian from Romans d'Isonzo (dated 1749) is examined, as well as two small pastel portraits of Saint Philip Romolo Neri and Saint Teresa of Avila, dating from the first half of the century and preserved at the Provincial Museums of Gorizia. The Istrian altarpiece from Cepic should most likely also be dated back to this time period. In the Pedena (Pican) Cathedral there is another painting that seems to be close in style to Pavona, portraying John the Baptist, Saint Vincent Ferrer and Saint Francis of Paola. The altarpiece was commissioned by Gorizia-born Bishop Bonifacio Cecotti (1697-1765), who ascended the episcopal throne in 1741. With the help of an annual revenue of 300 German guldens granted to him by Empress Maria Theresa or Austria in 1754, Cecotti was able to enlarge the church and renovate its four side-altars. Among these there is also the side-altar dedicated to John the Baptist and the recipient of the above-mentioned painting. In front of this altar is also the recumbent tomb of the prelate. Incidentally, it should be noted that the Pedena bishopric would be a suffragan of the archbishopric of Gorizia from 1752 onwards. Although the ecclesiastical ties thus seem to have favoured the relationship between the Habsburg Istria and the Gorizia region, the commissioner of the painting from Cepic should be looked for in secular circles. The village was, in fact, part of the seignory of Waxenstein (Kozljak), which was an allodial fief of the ducal branch of the Auerspergs. During the period in question, the holder of the benefit was Prince Henry of Auersperg (1697-1783), the likely commissioner of the altarpiece. Probatory of this thesis, in the absence of other documents, is the iconography of the very altarpiece with the Glory of Saint Francis of Paola: the Prince had been christened as "Heinrich Gregor Josef Johann Baptist Franz von Paula" and in 1726 had got married for a second time to the Baroness Francesca Trautson-Falkenstein (1708-1761), of whom there exists a portrait depicting her as a Franciscan Tertiary. Additional research in the parochial archives of Cepic could shed new light on the church as well as on Pavona and his work.

Well designed scintillator detectors, including such examples as ARSA, SAUNA, and XIA's "PhosWatch", can readily achieve the state of the art radioxenon detection limits required for nuclear explosion monitoring. They are also reliable, robust detectors that do not require cryogenic cooling for operation. All three employ the principle of beta-gamma coincidence detection to reduce background counting rates, using a BC-404 plastic scintillator to detect the betas and a CsI or NaI scintillator to detect the gamma-rays. As a consequence of this commonality of design, all three also display a "memory effect" arising from the diffusion of Xe into BC-404. Thus, when one sample is pumped out of the detector, a fraction remains behind, embedded in the BC-404, where it artificially raises the signal counting rate for the next sample. While this is not a fatal flaw in scintillator detectors, developing a method to eliminate the memory effect would significantly enhance their utility. This paper reports efforts to develop thin, amorphous Al2O3 films, deposited by atomic layer deposition (ALD) to act as diffusion barriers on the BC-404 surfaces exposed to radioxenon. Using radon as a convenient substitute for Xe, film thicknesses between 2 and 10 nm were originally investigated and found to show a memory effect to varying degrees. A second set of 20 and 30 nm films was then produced, which appeared to completely eliminate the radon memory effect, but, when consequentially tested with radioxenon, were found to exhibit xenon memory effects that were approximately half of the effect found on uncoated BC-404. We draw two conclusions from this result. The first is that it will be necessary to develop an improved method for depositing thicker ALD Al2O3 films at lower temperatures while still retaining high film quality. The second is that, since xenon is required to test for the xenon memory effect, we need a test method that does not require xenon radio-isotopes in order to facilitate screening large numbers of samples.
