A proposal for the use of Core and Buffer Zones to protect the heritage of the Cyrenean landscapes
No full textThe ancient landscapes surrounding Cyrene, which have been incredibly well preserved for centuries, have suffered more destructions in the past 7 or 8 years than in the whole of the last millennium. Urban encroachment, strong demographic pressure, unsustainable exploitation of resources and unplanned growth of infrastructures and services are threatening the archaeological heritage of this splendid site. The Department of Antiquities (DoA) has always struggled against these phenomena, but today the destructions are so great that the DoA is often powerless to act. This paper continues previous works on the damage to the Cyrenean necropoleis after 2011(Abdulkariem and Bennett, 2014; Al Raeid et al. 2016; Menozzi, Di Valerio et al. 2017; Menozzi, Tamburrino et al. 2017) and proposes strategies to help, on the basis of a preliminary report organised by the Mission of the University of Chieti in collaboration with the Departments of Antiquities of Cyrene and Tripoli, as requested by UNESCO. This preliminary step towards further improvements and needs to be discussed with other institutions and missions. The first part presents a proposal for controlling the core and buffer zones around Cyrene; the second part is an update on the recent damages to the necropoleis
PHERO SEMEROS e i contesti spezzati. Nuovi schemata iconografici dalla necropoli di Cirene: dal traffico illecito alla ricostruzione dei contesti
No full textThe
necropolis of Cyrene represents an unbelievable
context, very rich in elaborated architectures,
monumental funerary complexes and extraordinaire
archaeological finds. This huge and inestimable
site is still giving interesting news, especially
from the sculptural point of view. However, the
richness of this site and the unplanned and unsustainable
modern urban encroachment in the area
have determined for long time looting, vandalism
and even the destruction of elaborated and monumental
tombs. Numerous sculptures have been
robed during last years and often are brought outside
Libya to be sold illegally. Recently the Department
of Antiquities has recovered two egregious
sculptures, one of them from the southern necropolis
of Cyrene, while the second one has been recovered
in Tobruk by the army, with the help of the
DoA, before passing the Egyptian border. Two Libyan
colleagues (Abdulrhim S.Sharif and Said
Alannabi) are collaborating here with the report
concerning this statue from Tobruk, explaining
how the statue was robbed from Cyrene, for a certain
period was conserved illegally at Derna, probably
by a Daesh group, together with other objects
coming from Iraqi, Syria and Egypt, and then
was moved to be sold in Egypt, but fortunately
blocked by the army before passing the Libyan
border. The two statues are dating to the 4th-3rd century
BC and are gorgeous examples of Cyrenaican
sculptures. They are both in Paros marble and present
seated female statues, with elaborated dressing
and iconographic schema very well known for
strict parallels with the so called Cyrenaican Funerary
Goddesses. Moreover, a third statue, quite similar
for position, gesture, dressing and iconography,
has been recently sold through web and is now in a
private collection, and the traces of its ‘trip’ have
been lost. However is important to present also this
third statue together with the other two which are
very similar, and to reconstruct at least, their cultural
context. Moreover, the statue coming from
the southern necropolis presents also an inscription
with the name Phero Semeros, that is Phero,
daughter of Semer, which can find parallels in Cyrene
for both names: a detailed epigraphic and
onomastic study of C. Dobias Lalou is here presented
in appendix. Thanks to the work of the DoA
we can reconstruct the context of this statue,
which is a quite interesting and elaborated tomb,
the S197, which has never been published before,
but fortunately studied by Luca Cherstich, of
Chieti University. Moreover, during a recent
mission, also Oscar Mei, of Urbino University, has
been able to control the area, so we now know how
the context was and how it is now. Therefore this
paper intends, with the contributions of several
scholars of different Missions, both Italian, of
Chieti (Oliva Menozzi, Luca Cherstich, Silvano
Agostini) and Urbino (Oscar Mei) Universities as
well as of the French Mission (Morgan Belzic and
Catherine Dobias Lalou) and of the soas (School
don
(Igor Cherstich, ucl), to collaborate in studying
and publishing the sculptures, in reconstructing
the ‘broken contexts’ due to the looting, and try to
understand the routes of the illicit traffic of these
Cyrenaican sculptures up to the black market and
to the international auctions. The paper represents
a great example of how the collaboration among
missions and DoA can help in recovering, relocating
and re-contextualizing precious sculptures,
which have otherwise contexts ‘broken’ forever
An assessment of the impact of possible CAP reform scenarios on Romanian agriculture
No full textUsing a simplified model, with key-variable the prices of two different possible scenarios of CAP reform after 2013 (moderate and radical), this paper present a comparison between the price effects of implementation of each reform scenario at 2015 horizon on Romanian agriculture. This short analysis shows that, under the presented hypotheses, the net welfare effect, due to the price changes, for the selected products, is positive in both reform scenarios, yet greater in the case of the radical reform. Integrated in the large context of Romanian development, it seems that the influence of CAP reform upon agriculture and rural areas will be most likely a gradual one: an interpenetration between the two scenarios is foreseeable, starting with the moderate reform that will dominate the period around 2013, the reform measures acquiring a more radical character afterwards.CAP reform, Romania, welfare effects, Agricultural and Food Policy,

An improved procedure to test CMOS ICs for Latch-up
No full textAn improved, more complete strategy for latch-up testing of CMOS ICs is proposed in order to take into account important effects that have been neglected by standard procedures, but which are shown to reduce considerably the circuit resistance to latch-up. These phenomena include interactions among carriers injected by different p-n-p-n structures, voltage drops on power supply and ground lines caused by output pin load currents, and effects of power supply voltage and chip heating. All experiments with regard to this work have been performed by means of automatic test equipment, which provides the possibility of completely controlling the circuit state and operating conditions during testin
Rich, Sturmian, and trapezoidal words
No full textIn this paper we explore various interconnections between rich words, Sturmian words, and trapezoidal words. Rich words, first introduced by the second and third authors together with J. Justin and S. Widmer, constitute a new class of finite and infinite words characterized by having the maximal number of palindromic factors. Every finite Sturmian word is rich, but not conversely. Trapezoidal words were first introduced by the first author in studying the behavior of the subword complexity of finite Sturmian words. Unfortunately this property does not characterize finite Sturmian words. In this note we show that the only trapezoidal palindromes are Sturmian. More generally we show that Sturmian palindromes can be characterized either in terms of their subword complexity (the trapezoidal property) or in terms of their palindromic complexity. We also obtain a similar characterization of rich palindromes in terms of a relation between palindromic complexity and subword complexity
Extraction of the Series Resistances and Effective Channel Length of GaAs MESFETs by means of Electrical Methods
No full textThe authors present a numerical study on electrical methods to measure the source and drain resistances and the effective channel length of state-of-the-art gallium arsenide MESFETs. In particular, the effects of scaling on the physical meaning and gate voltage dependence of the extracted values are investigated. Fringing effects at the gate edges are found to be responsible for a substantial bias dependence of the series resistances, and hence for possible inaccuracies of extraction procedures that overlook such phenomena. A novel extraction technique is also proposed to overcome in part the limitations of conventional approaches
Effects of the interaction of neighboring structures on the Latch-up behavior of C-MOS ICs
No full textAn experimental investigation on the interaction between different parasitic devices in CMOS ICs from the point of view of latchup triggering is outlined. The study, carried out by means of ad hoc test structures, shows that this interaction: (a) can lead to significant increase in latchup susceptibility; (b) can involve devices very distant from one another; and (c) is not always suppressed by guard ring protections. The main features of the experimental results are discussed and explaine
