Perforated coins from graves at the Viminacium necropolis of Više Grobalja
A common problem that occurs when interpreting finds of perforated Roman
coins is whether they had been perforated in Roman times or later. Hence, the
specimens that originate from an undisturbed archaeological context, as is
the case with finds from the Viminacium necropolis of Više Grobalja, are
indispensable. A total of 47 perforated coins were discovered: 31 with a
single and 16 with three perforations. The analysis of the context of the
finds, in some specimens, allows the confident assertion that they had
constituted a part of jewellery. [Projekat Ministarstva nauke Republike

Perforated coins from graves at the Viminacium necropolis of Pećine
A common problem that occurs when interpreting finds of perforated Roman
coins is their function and whether they were perforated in Roman times or
later. Hence, the specimens which originate from an undisturbed
archaeological context, as is the case with finds from the Viminacium
necropolis of Pećine, are indispensable. A total of 45 perforated coins were
discovered at Pećine: 23 from graves and 22 from sacrificial areas. [Project

METAL DELM - metal avrelianis contribution to the study of mining coins and anonymous quadrantes
In the course of rescue archaeological investigations at the Viminacium
necropolis of Vi{e Grobalja in 1984, one anonymous quadrans of the VIII
Apollo group was discovered (cat. 1). It was discovered in trench 63 in the
immediate vicinity of a grave with an inhumation (G 343) that, besides two
pottery vessels, also yielded as grave offerings one as of Faustina the
Elder, minted after her death, in AD 141. Other finds presented here are four
specimens of Roman mining coins from the private collection of Petar Fajfri}
from [abac (cat. 2-5). All specimens come from the well known site of Duge
Njive in the area of the village of Banatsko Polje (Bogati} borough) where,
by all appearances, are the remains of a vicus or smaller settlement. Five
specimens of mining coins from that site have already been published. Both
mining coins and anonymous quadrantes represent, in general, rare types of
numismatic finds. Nine anonymous quadrantes are known so far from the
territory of Serbia (Table 1) and the provenance is known for three specimens
from the region of Guberevac-Babe (Kosmaj), housed in the National Museum in
Belgrade. All three belong to the Minerva group with an owl facing to the
right represented on the reverse. For two more anonymous quadrantes the place
of discovery is known: one specimen comes from Singidunum and belongs to the
Mercury group and the other that was found at Viminacium and is the subject
of this paper is of the Apollo group. There are four more specimens from
unknown sites for which it is assumed that they come from the Upper Moesia
territory. Two of them are from the Vajfert collection and two from the
Kovačević collection in the National Museum in Belgrade, There has, however,
been a somewhat greater number (38) of Roman mining coins discovered in
Serbia (Table 1). We know the finding locations of 25 of them: from the
Kosmaj area (Babe, Guberevac and Stojnik), the Ibar valley (from the vicinity
of TrepÄŤa and So~anica), Ritopek, Belgrade and Banovo Polje. We do not know
the provenance for the remaining 13 specimens, but it is assumed that they
come from the Upper Moesia territory. The anonymous quadrans discovered at
the Viminacium necropolis of Vi{e Grobalja belongs, as previously mentioned,
to the Apollo group. The only analogous piece known from the territory of
Serbia comes from the Kovačević collection in the National Museum in
Belgrade. Most of the known specimens belong to the Minerva group (3), there
are two pieces of the Mars group, one of Mercury and one undetermined (Table
1). The anonymous quadrans from Viminacium is the second of its kind
discovered along the Upper Moesia section of the Danube limes. The quadrans
from Singidunum was found in the zone of the Roman Singidunum harbour and
belongs to the Mercury group. Five specimens of mining coins in the Fajfri}
collection published earlier belong to the same METAL DELM type with a bust
of Diana on the obverse and deer on the reverse. To this group should be
added our specimen cat. 2, and as such this type is the best represented
group (6) of mining coins from the site of Duge Njive at Banovo Polje. The
same group, Metalli Delmatici, also includes cat. 3, which has the head of
Mars on the obverse and armour on the reverse. Then there are the two
identical quadrantes of the group MetalliAureliani (cat. 4, 5) and their only
analogy from the territory of Serbia is the quadrans from the Kosmaj area.
The nine specimens of mining coins from the site of Duge Njive at Banovo
Polje make up a considerable proportion of the total number of mining coins
in Serbia. Their importance is even greater because of the fact that seven
METAL DELM specimens are the first of that group for which we know the
finding location. Finds of the anonymous quadrans from the Viminacium
necropolis of Vi{e Grobalja and the mining coins from Banovo Polje complete
the picture of the topography of this kind of numismatic finds. Their
publishing is, mainly because of the known provenance, more significant for
future investigations
Seasonal variation in marine-snow-associated and ambient-water prokaryotic communities in the northern Adriatic Sea
The structure and activity of prokaryotic communities were determined in marine snow and in the ambient water of the northern Adriatic Sea in different seasons (autumn, spring and summer). The seasonal variation in the composition of marine-snow-associated and ambient-water bacterial communities was assessed by T-RFLP (Terminal Restriction Fragment Length Polymorphism) on the 16S rRNA gene (16S rDNA) and 16S rRNA transcript (16S rRNA) level. On the 16S rDNA level, the bacterial community composition of the marine snow and ambient water was similar in summer and autumn, but not in spring. In contrast, on the 16S rRNA level, indicative of the active bacterial community, the marine-snow-associated bacterial community was different from that of the ambient-water, and different from the bacterial community on the 16S rDNA level, except in autumn. To phylogenetically characterize the bacterial and archaeal community composition associated with marine snow and the ambient water, clone libraries of 16S rDNA and 16S rRNA were constructed from 2 contrasting seasons. Phylogenetic profiling revealed a higher similarity among bacterial communities in summer compared to late autumn. Certain bacterial and archaeal groups were exclusively associated with summer or autumn marine snow, suggesting that marine-snow-associated prokaryotic communities are subjected to successional changes similar to ambient-water communities. Moreover, the presence of bacterial groups enriched in marine snow including Vibrionales and sulphate-reducing bacteria is consistent with niche partitioning and metabolic adaptations of the particle-associated microbiota
Harmonised reference genes and PCR assays for GMO quantification
Chapitre 16International audienceGMO production has been accompanied, in several countries, by a number of regulations that set mandatory requirements for GMO traceability and labelling in relation to a relative GMO content. Analytical methods have been developed to trace GMOs, including the taxon from which the GM crop originates. The latter are referred to as reference assays and taxon is preferred to species as several crops refer at subs-species levels. This chapter examines the currently available reference assays and describes several bottlenecks raised by the required specificity and stability of these reference assays. It includes a proposal to establish a core collection of taxa until the issue of availability of accurate reference assays is solved
