This research highlights a recent discovery, at Poetovio, among a huge number of standard imported Roman oil lamps, of an open-shape copper-alloy lamp to be used with tallow (type Loeschcke XXV). This form, together with its clay counterpart (type Loeschcke XI), is typical of the northern Roman limes provinces where its production and usage was almost exclusive. To understand the uniqueness of this find so far south, the authors have mapped all the known parallels made of different metals. They also present a short introduction to the very eclectic clay variant, which is marginal almost everywhere except for Trier, where it constitutes by far the most common type, quantitatively speaking, of Roman lamps found in situ.

This research highlights an open-shape copper-alloy lamp to be used with tallow (type Loeschcke XXV), recently discovered at Poetovio, among a huge number of standard imported Roman oil lamps. This form, together with its clay counterpart (type Loeschcke XI), are typical of the northern Roman limes provinces, where they were produced and used almost exclusively. Finding such a lamp so far south merits note, hence the discussion of the distribution of known parallels, made of different metals, as well as a brief consideration of a very eclectic clay variant, which is marginal almost everywhere except at Trier, where it constitutes by far the most numerous type of Roman lamps found in situ.

Matteo Moronzon, a member of the Venetian family of woodcarvers, was mentioned for the first time in 1407 according to the present known archival documents. Probably after being trained in his father's workshop in Venice, he moved to Zadar with his family – his wife Francisca and sons Pietro and Francesco. In 1418 he undertook the commission of furnishing carved choir stalls for the cathedral of St. Anastasia in Zadar. Various archival documents testify that Matteo lived and worked in Zadar for many years. Therefore it can be assumed that he probably founded his own workshop in Zadar where his son Francesco was trained too. Apart from the attempt to reconstruct Matteo's life and career, the aim of this paper is to interpret one important woodcarving work of art preserved in situ: choir stalls in the former cathedral of Rab, today the arch parish church of the Assumption of the Blessed Virgin Mary in Rab. Without doubt Matteo was the master carver in the production of the choir stalls in Zadar. Since he lived in Zadar it was not unusual that he had the main role in carving the stalls. In Zadar the selection of motives is more balanced and there are no significant differences in the modelling of decorative elements. However, the question whether Matteo carved absolutely everything or he had assistants arises. Considering the amount of work that had to be done it must be assumed that he had assistants who participated in work and helped him to shape the stalls. However, in literature Matteo was considered the only and undisputed author of the choir stalls in Zadar, mostly because of the preserved document. The analysis of the choir stalls in Rab by Ivo Petricioli as well as their evident formal and stylistic similarities with the stalls from the cathedral in Zadar have led to the general acceptance of the hypothesis that they were carved at the workshop of Matteo Moronzon. However, a comprehensive comparative analysis that could confirm that hypothesis was still missing. The analysis of the details and the whole led to the overall conclusion that there were a huge number of similarities between the choir stalls in Rab and Zadar. Therefore it was concluded that Matteo was the principal designer of the choir stalls in Rab who also carved the best parts in Rab, while others, less successful parts, were made by his apprentices and assistants who at the time lived on the island of Rab. In this respect, if Matteo was accepted as the author of the choir stalls of the cathedral in Zadar he must also be accepted as the author of the choir stalls from the excathedral in Rab.

Cytogenetic Analyses

The translocation t(2;5)(p23;q35), discovered in CD30+ anaplastic large cell (ALC) lymphomas, creates a potentially oncogenic fusion gene, part of which is contributed by a novel tyrosine kinase, ALK. Absence of ALK expression from normal hematolymphoid cells provides a basis for the morphologic assessment of t(2;5). The distribution of the t(2;5) in ALC lymphomas and Hodgkin's disease (HD), as assayed by nonmorphologic methods, is controversial. We used in situ hybridization and/or immunohistology to show ALK gene products in 85 ALC lymphomas, 82 HD cases, 40 other lymphoproliferations, as well as in 6 HD- and 4 ALC lymphoma-derived cell lines. ALK gene products were restricted to t(2;5)-positive ALC lymphoma cell lines and tumor cells of 16 primary non-B cell, common-type ALC lymphomas. These were mainly from young patients with initial lymphonodal disease. ALK expression was not detectable in any other specimen, including all cases of HD and HD-like type ALC lymphoma as well as secondary ALC lymphomas. Full congruence was noted for labeling results obtained with both methods. In agreement with cytogenetic analyses, but at variance with recently published studies, ALK gene expression distinguishes a subset of ALC lymphomas from other CD30+ lymphomas, including HD. The results do not support concepts attributing a significant role to the t(2;5) in the development of HD.

In Situiron nanoparticles can be formed during copper alloy solidification. Here we consider ZCuSn3Zn8Pb6Ni1FeCo alloy.It is noted that high undercooling is the motive power of nanoparticles during solidification , which would act as heterogeneous nuclei to achieve outstanding contribution for grain refinement compared to ZCuSn3Zn8Pb6Ni1 alloy. Convection of the melt inhibit the growth of nanoparticles by way of prohibitting the deposition of iron atoms on the surface.This technique offer new enlightenment for the control of in-situ nanoparticles formed during alloy solidification,and also opens the door to a new class of dispersed nanoparticles strengthened materials.
