After African trades: changing in Cignana landscape between Late Antiquity and Medieval age

2017

International audience; In many parts of Sicily, the Late Antiquity represents a period of strong transformation in settlement patterns and landscapes. These changes occur also on an area 20 km SE from Agrigento, on the southern coast of the island: this is the territory around the imperial villa of Cignana (2nd-3th century AD), where the University of Palermo carried out some surveys from 2007. During the surveys more than 30 new topographic units of Late Antiquity were detected: some of them are big and accurately dated, others are small and difficult to interpret. Usually, they have located in easily accessible places, close to springs and the road system. Principally African pottery all…

Importation and Trade of African Pottery in the Ancient Ecclesia Carinensis During the Late Roman Age

2015

The territory of Carini, on the northwest coast of Sicily, 30 km from Palermo, is often mentioned by ancient sources. According Thucydides in this area was located the ancient Hykkara. Itinerarium Antonini recalls the statio of Hykkara along the via Valeria. This route in Late Antiquity became very important for the deportatio ad aquam of the agricoltural products. Gregorius Magnus in the epistles (VI century A.D.) mentions a diocese of Karines, as witnessed alike by the acts of synods to 782. The archaeological excavations, still ongoing, in the Early Christian cemetery nearby the little modern town of Villagrazia di Carini have revealed the presence of a strong Christian community. The se…

Costruzione dei rilevati stradali e ferroviari: valutazione delle metodologie di progetto delle terre trattate con calce

2010

Nella costruzione delle opere civili e, soprattutto, delle infrastrutture di trasporto, elemento qualificante per la minimizzazione degli impatti economici ed ambientali è l’adozione del trattamento con calce dei terreni argillosi di scavo, di per sé non idonei ad essere impiegati nei manufatti in terra, e la loro utilizzazione - previo trattamento con calce, appunto - per la costruzione di rilevati ed altre opere in terra. La tecnica del trattamento con calce delle terre argillose permette di ottenere diversi vantaggi di ordine tecnico, economico ed ambientale. I progressi tecnologici conseguiti negli ultimi decenni, particolarmente per quanto riguarda gli studi di progetto, i mezzi di can…

A study of the novel anti-inflammatory agent florifenine topical anti-inflammatory activity and influence on arachidonic acid metabolism and neutroph…

1995

We have evaluated the effects of the novel anti-inflammatory agent florifenine, 2-(1-Pyrrolidinyl)ethyl N-[7-(trifluoromethyl)-4-quinolyl]anthranilate, on topical inflammation in mice, free radical-mediated reactions, arachidonic acid metabolism and some neutrophil functions. Topical administration of florifenine produced dose-related anti-inflammatory activity in 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced ear oedema and with a lower potency, in the response induced by arachidonic acid (AA). Florifenine also inhibited neutrophil migration and PGE2 content in the inflammed ears. In human whole blood, florifenine was a potent and selective inhibitor of TXB2 generation. This anti-infla…

Discovery of novel anti-inflammatory drug-like compounds by aligning in silico and in vivo screening: The nitroindazolinone chemotype

2011

In this report, we propose the combination of computational methods and in vivo primary screening in zebrafish larvae and confirmatory in mice models as a novel strategy to accelerate anti-inflammatory drug discovery. Initially, a database of 1213 organic chemicals with great structural variability - 587 of them anti-inflammatory agents plus 626 compounds with other clinical uses - was divided into training and test groups. Atom-based quadratic indices - a TOMOCOMD-CARDD molecular descriptors family - and linear discriminant analysis (LDA) were used to develop a total of 13 models to describe the anti-inflammatory activity. The best model (Eq. (13)) shows an accuracy of 87.70% in the traini…

Isolation of two triterpenoids and a biflavanone with anti-Inflammatory activity from Schinus molle fruits.

2003

Three compounds with anti-inflammatory activity were isolated from Schinus molle fruits. Two of the compounds were identified as 3- epi-isomasticadienolalic acid ( 1), isomasticadienonalic acid ( 2) and chamaejasmin ( 3). Triterpenes 1 and 2, and biflavanone 3 were tested on two models of mice paw inflammation: one of acute inflammation, induced by subcutaneous injection of either phospholipase A (2) (PLA (2)) or carrageenan in the paws of mice, and one of chronic inflammation in the form of eczema, provoked by repeated administration of TPA to the ears of mice. On the PLA (2)-induced mouse paw oedema, only 2 was active (30 mg/kg, 66 % inhibition at 60 min), whereas all compounds reduced th…

Union recognition in Britain's offshore oil and gas industry: implications of the Employment Relations Act 1999

2004

The Employment Relations Act 1999 (ERA) has provided trade unions in the UK with new opportunities for achieving recognition. After a long history of anti-unionism in the offshore oil and gas industry, employers have voluntarily ceded recognition to Trades Union Congress (TUC)-affiliated trade unions. The legitimacy of this recognition process has been contested by the non-TUC Offshore Industry Liaison Committee (OILC), an offshore workers’ union, seeking to act as a recognised bargaining agent. The ERA may be promoting ‘business friendly’ agreements at the expense of claims to recognition of other bargaining agents and of democratic employee choice.

Trade, innovation and interdependence : a spatial econometric approach

2015

This thesis studies the consequences for innovation of international trade allowing for spatial interdependence. Indeed, the mechanisms through which international trade affects innovation are based on highlighting factors that, because they are the source of increasing returns, represent real engines of the growth. Yet, the accumulation process of these factors depends on effects which are constraints in space .First, trade flows by which technology is supposed to transmit between countries are interdependent. Second, the results highlighted in existing literature capture only the direct effect of trade on innovation. However, it is possible that a country benefits technology from an anoth…

A critical review of life cycle assessment benchmarking methodologies for construction materials

2022

As it stands, the construction sector accounts for a significant proportion of global emissions. The majority of these emissions can be associated with material production. As a result, the importance of quantifying these environmental impacts is continually increasing. However, there is a current lack of guidance and methodologies regarding how to benchmark the impacts of construction products, and thus achieve more transparent environmental reporting and decision-making. Therefore, the aim of this study was to review engineering life-cycle assessment (LCA) literature and applicable standards to identify the key methodological variables required and the key steps for a sector-wide methodol…
