Tell Shiyukh Tahtani, Nord Siria. Relazione sull'attività della Missione Eufrate nell'anno 2008.
2008
Survey and excavations in the Middle Euphrates Valley, Syria. 2008 Season.
Tell Shiyukh Tahtani on the Euphrates. Highlights of the last excavation seasons
2010
In recent years (2006-09) the University of Palermo Euphrates expedition has continued rescue excavations at Tell Shiyukh Tahtani (the “Lower Hill of Sheikhs”) as part of the Tishreen Dam Salvage Project. Located on the left bank of the River south of Jerablus, in the land that once was the Carchemish district, this small mound has revealed a long occupation sequence from around 3.000 B.C. to Byzantine and early Islamic times. During the last three seasons we mainly concentrated in the investigation of the eastern slope of the upper tell (Area CD), where a continuous Bronze Age occupation has been detected. Apart from the later levels (EB IV, Middle and Late Bronze Age), one of the main goa…
Sistema mafioso e anticomunità. Percorsi per leggere le comunità criminali.
2018
The studies on to mafia feeling take sprout from reflections, bibliographical searches and workshop conducted by a group teachers of the athenaeum of Palermo at the end of the years ’80. The incipit from which the authors have departed is that in Sicily the attitude towards the mafia crime it constitutes a ‘cultural theme’, consequential from the inner of transpersonal relationships typical of the social context and above all family in which the subjects in evolutionary age are found. This contribution get up from the psyco-pedagogic theme of the education and the development of community in criminal contexts, in a society without values that it loses the same sense of community and affilia…
How Pioneering Managers Strive to Integrate Social Risk Management in Government Debt Collection
2019
This study explores risk management issues in local government-owned enterprises in accordance to the third wave of governance, organization and management logics of Public Administration: the Public Value approach. However, the coexistence between the emerging Public Value approach and the more traditional and consolidated ones is often difficult, also because of the resistance of shareholders who may not consider the management of system-level risks as a priority mission for their company. For this reason, we have analysed the strengths and weaknesses of the Traditional Approach and the New Public Management approach in the public sector management. The case study presented reveals some i…
A micellar multitasking device: sensing pH windows and gauging the lipophilicity of drugs with fluorescent signals.
2010
A multitasking fluorescent device can be obtained by forming micelles of Triton X-100, containing a lipophilic macrocyclic Cu(2+) complex and the coordinating fluorophore Coumarin 343 (C343), which features a COOH moiety. At low pH the two micellised components do not interact, and the fluorescence of Courmarin 343 (C343) is intense. At intermediate pH, C343 is deprotonated and coordinates to the Cu(2+) centre in its apical position, with fluorescence quenching. At higher pH the deprotonated C343 is displaced from Cu(2+) by the formation of an OH(-) complex, and the fluorescence is revived. This allows the system to carry out its first task as it behaves as an "on-off-on" fluorescent sensor…
Entre Mediterraneo y Atlantico: reflexiones sobre las fronteras
2017
Nell’ultima decade del secolo scorso, il tema della “frontiera” si è imposto tanto nel dibattito politico, nazionale e internazionale, quanto nella riflessione storica (ma non solo) volta a recuperare nel passato le origini di problematiche di estrema attualità. Da allora, le complesse dinamiche sociali che hanno investito in particolar modo l’area mediterranea, hanno fatto sì che l’interesse per il significato storico delle frontiere non si esaurisse, bensì allargasse progressivamente lo spettro d’indagine per riportare alla luce processi di integrazione ed esclusione, di contrattazione e opposizione. La messa in discussione di identità e appartenenza, risultato della progressiva intensifi…
Fronteras: procesos y prácticas de integración y conflictos entre Europa y América (siglos XVI-XX)
2017
The borders have attracted the attention of historians and social scientists as spaces of conflict, traffic, exchange or cooperation. The volume analyzes territories of contact as a historical global reality and not as isolated entities
The inhibitory neural circuitry as target of antiepileptic drugs.
2001
Impairments and defects in the inhibitory neurotransmission in the CNS can contribute to various seizure disorders, i.e., gamma-aminobutyric acid (GABA) and glycine as the main inhibitory neurotransmitters in the brain play a crucial role in some forms of epilepsy. Recent advances in deciphering the molecular basis of the GABAergic and glycinergic systems has been achieved by means of cloning techniques and gene targeting strategies in animals, contributing to the understanding of drug action. As well, several anticonvulsive substances emerged which target key molecules of the inhibitory systems. Employment of recombinant expression systems, including, but not restricted to the inhibitory c…
Effects of GABA-transporter (GAT) inhibitors on rat behaviour in open-field and elevated plus-maze.
1999
The behavioural consequences of inhibition of gamma-aminobutyric acid (GABA) uptake were studied. Two GABA uptake inhibitors, tiagabine and SKF 89976-A, were administered to rats, and behaviour was analysed 30 min later in a standard open field, an enriched open field, and an elevated plus-maze. Eight groups of animals received either saline (0.9%), tiagabine, or SKF 89976-A. At a dose of 18.5 mg/kg, tiagabine, an established antiseizure drug, impaired motor coordination, enhanced exploratory activity and reduced anxiety related behaviour. SKF 89976-A exhibited minimal effects over the dose range tested. These results indicate that inhibition of GABA uptake might be a pharmacological strate…
Differential annotation of tRNA genes with anticodon CAT in bacterial genomes.
2006
We have developed three strategies to discriminate among the three types of tRNA genes with anticodon CAT (tRNA(Ile), elongator tRNA(Met) and initiator tRNA(fMet)) in bacterial genomes. With these strategies, we have classified the tRNA genes from 234 bacterial and several organellar genomes. These sequences, in an aligned or unaligned format, may be used for the identification and annotation of tRNA (CAT) genes in other genomes. The first strategy is based on the position of the problem sequences in a phenogram (a tree-like network), the second on the minimum average number of differences against the tRNA sequences of the three types and the third on the search for the highest score value …
