Le conchiglie di Lamarck come beni culturali

2012

Con questo contributo si è voluto ricordare che nella turbolenta Francia nel 1793 per la prima volta i beni naturali vengono ufficialmente riconosciuti anche come beni culturali facenti parte del patrimonio di un popolo, che li deve custodire e tutelare. Il tutto era scaturito dalla necessità di salvare dalla distruzione due acquasantiere costituite da 2 valve di tridacna, una conchiglia esotica, presenti nella Chiesa di S. Sulpice a Parigi. A questo importante evento partecipò attivamente anche Jean Baptiste Lamarck, Professore di Zoologia degli Insetti e dei Vermi presso il Museo Nazionale di Storia Naturale di Parigi. Proprio dallo studio delle conchiglie attuali, comparate con quelle fo…

Effects of pyrolysis conditions on the porous structure development of date pits activated carbon

2012

International audience; Activated carbons were prepared from biomass of Algerian date pits for developing efficient and cheap adsorbents in the aim to remove heavy metals from waste water. Carbon adsorbents were obtained following two successive treatments: pyrolysis under dry nitrogen flow and physical activation under wet nitrogen flow. Pyrolysis process was optimized by varying some operating parameters such as temperature, nitrogen flow, heating rate and pyrolysis hold time in order to determine their effects on the porous structure development of date pits activated carbon. Chars obtained from pyrolysis process were activated with the same operating conditions (activation temperature o…

Limiting transport properties of lanthanide and actinide ions in pure water

2003

Summary The limiting transport properties, i.e. the limiting ionic conductivity (λ°) and the limiting diffusion coefficient (D°), of lanthanide and actinide ions at 298.15K have been calculated by means of the microscopic version of the Stokes–Einstein law involving (i) the effective charge and the ionic radius of the ions and (ii) the ion micro-viscosity, i.e. the viscosity of the hydrated water molecules in the vicinity of the ion. The latter quantity was derived from the variation of the dynamic properties of the water molecules in the first hydration shell with the surface charge density of common mono-atomic cations of various charges. The obtained results were found to be consistent w…

Taken from the sea, reclaimed by the sea: The fate of the closed harbour of Elaia, the maritime satellite city of Pergamum (Turkey)

2013

Abstract During Hellenistic times, when the Pergamenian kingdom was prospering, Pergamum was operating an important harbour, used by merchants and military at the city of Elaia. This paper focuses on the development, utilisation and decay of the closed harbour of Elaia, which is discussed in the context of the landscape evolution of the environs of the ancient settlement. Based on geoarchaeological, archaeological and literary evidence, the construction of two harbour moles in order to provide shelter against wave action and enemies can be attributed to the early Hellenistic period. Geoelectric measurements revealed the construction profile of the moles. Coring evidence indicated that toget…

Étude théorique de la dynamique du réseau de PbTiO3 dans la phase quadratique

1999

Resume La dynamique du reseau du titanate de plomb PbTiO 3 est etudiee en phase quadratique a l'aide d'un modele a coquille tenant compte des polarisabilites electroniques des ions de la maille elementaire et des interactions a longue et a courte portee. Les resultats de nos calculs mettent en evidence le role important joue par l'anisotropie de la polarisabilite electronique de l'oxygene. Il est montre aussi que les courbes de dispersion des phonons calculees dans la premiere zone de Brillouin sont en bon accord avec l'experience.

Comparison of numerical modelling techniques for impact investigation on a wind turbine blade

2019

Wind turbine blades are exposed to numerous impact risks throughout their lifetimes. The impact risks range from bird collisions during operation to impacts with surrounding structures at the time of transportation and installation. Impact loads on the fibre composite blades can induce several complex, simultaneously interacting and visually undetectable damage modes and have a high potential to reduce the local and global blade stiffness. An assessment of such impact-induced damages is therefore necessary and usually involves high computational costs using numerical procedures, especially when analysing large composite components. To minimise this computational expense, different numerical…

Lilibeo al tempo di Cicerone

2021

The volume that sees the light today is the fruit of the Study Day on "Lilibeo at the time of Cicero" held in Marsala, in the conference room of the Museo Lilibeo, on 3 May 2019 thanks to the joint effort of the Museum and the Culture and Society Department of the University of Palermo. In the short term, important changes in the council organizational structure, they led to the establishment of the Archaeological Park of Lilibeo including in a unitary structure the Lilibeo Regional Archaeological Museum, the archaeological area of ​​Capo Boeo, which represents the main nucleus, and other state-owned archaeological areas of the urban fabric of Marsala.
