Bacterial Viruses Subcommittee and Archaeal Viruses Subcommittee of the ICTV: Update of taxonomy changes in 2021
2021
In this article, we – the Bacterial Viruses Subcommittee and the Archaeal Viruses Subcommittee of the International Committee on Taxonomy of Viruses (ICTV) – summarise the results of our activities for the period March 2020 – March 2021. We report the division of the former Bacterial and Archaeal Viruses Subcommittee in two separate Subcommittees, welcome new members, a new Subcommittee Chair and Vice Chair, and give an overview of the new taxa that were proposed in 2020, approved by the Executive Committee and ratified by vote in 2021. In particular, a new realm, three orders, 15 families, 31 subfamilies, 734 genera and 1845 species were newly created or redefined (moved/promoted). Supplem…
The petrology of two distinct granulite types in the Hengshan Mts, China, and tectonic implications
2005
Abstract The Archean to Proterozoic Hengshan Complex (North China Craton), comprises tonalitic and granodioritic gneisses with subordinate mafic lenses, pegmatites and granites. Amphibolite facies assemblages predominate, although granulite-facies relics are widespread, and greenschist-facies retrogression occurs in km-wide shear zones. Mafic lenses, locally abundant, occur as strongly deformed amphibolite (hornblende+plagioclase) boudins or sheets. In contrast to previously published models we find two series of mafic rocks with distinctly different granulite-facies evolutions. In the north of the Complex, relict high-pressure mafic granulites are garnet+clinopyroxene-bearing rocks with a …

Le Tombe a Tempio di Norchia: dal rilievo all’anastilosi virtuale e alla ricostruzione tridimensionale
2018
Le attività di ricerca presentate in questo contributo sono state essenzialmente finalizzate al rilievo delle facciate delle due tombe presso la necropoli dell’Acqualta e alla documentazione della porzione ovest del frontone della Tomba occidentale (sinistra), conservato al Museo Archeologico Nazionale di Firenze1275. Tali rilievi, effettuati con tecniche indirette, sono stati realizzati, oltre che come basi documentali per lo studio dei due monumenti, anche in funzione della creazione di modelli tridimensionali, che sono stati utilizzati, in particolare, per lo studio ricostruttivo e il restauro virtuale delle facciate rupestri; quest’ultimo si è basato sia sul prospetto bidimensionale che…
Color degradation mapping of rock art paintings using microfading spectrometry
2021
[EN] Rock art documentation is a complex task that should be carried out in a complete, rigorous and exhaustive way, in order to take particular actions that allow stakeholders to preserve the archaeological sites under constant deterioration. The pigments used in prehistoric paintings present high light sensitivity and rigorous scientific color degradation mapping is not usually undertaken in overall archaeological sites. Microfading spectrometry is a suitable technique for determining the light-stability of pigments found in rock art paintings in a non-destructive way. Spectral data can be transformed into colorimetric information following the recommendations published by the Commission …
The President of the gold diggers: Sources of power in a gold mine in Burkina Faso
2003
The article provides an example of how 'formal' and 'informal' modes of power and legitimacy, as well as material and symbolic leadership resources, may intersect and interrelate. It analyses the sources of power that a Big Man in West Africa mobilised in order to appropriate mining rights and to establish leadership in a gold mining camp. As an entrepreneur in an economic field directly regulated by state laws and authorities, he has to operate within these structures while at the same time subverting them by creating a 'system of personal power' that resembles Sahlins' classic model of the Big Man in Melanesia. Although he is elected to represent the gold diggers, his leadership position …
Integrated use of unmanned aerial vehicle photogrammetry and terrestrial laser scanning to support archaeological analysis: The Acropolis of Selinunt…
2021
Southwestern Sicily is an area of infrequent seismic activity; however, some studies carried out in the archaeological Selinunte site suggest that, between the fourth century BC and the early Middle Ages, probably at least two earthquakes strucked this area with enough energy to damage and cause the collapse and kinematics of much of the architecture of Selinunte. Take into account that, in 2008, a noninvasive archaeological prospection and traditional data gathering methods along the Acropolis north fortifications were carried out. Following these first studies, after about 10 years, a new geophysical campaign was carried out. This second campaign benefited from the application of modern t…
ROMAN DACIA IN THE DIGITAL ERA
2020
The study of Roman Dacia in the last two centuries produced thousands of articles, studies, monographs and proceedings and revealed at least 3800 archaeological sites from the short period of existence of the province between 106-270 AD. The large quantity of material evidence – epigraphic, figurative, ceramic, architectural and numismatic – is constantly growing due to the numerous rescue excavations in the last two decades. The emergence of digital humanities and the possibilities of digital era created new perspectives in cataloguing, collecting and presenting archaeological big data. The article presents some of the major results of digital humanities focusing on the digitization of the…
Pottery decoration in the Neolithic of Kaf Taht el-Ghar (Tetouan, Morocco). AGRIWESTMED Works 2012
2021
Presentamos el estudio de los restos cerámicos de la fase neolítica de Kaf Taht el-Ghar (Mechrouha, Tetuán, Marruecos), enfocado principalmente en el análisis de técnicas y patrones decorativos. Ello cuenta con el interés añadido de corresponder, en su fase antigua, a las cerámicas asociadas a las primeras evidencias de agricultura y ganadería en el Magreb Occidental, encuadradas en el tercer cuarto del VI milenio cal AC. En dichas decoraciones dominan impresiones variadas, en particular las realizadas con concha estriada y lisa, peine y de cypraea. El uso de tales técnicas podría incluir estas primeras producciones cerámicas dentro del mundo impresso-cardial de la Europa mediterránea centr…
PATRIMONIO ARCHITETTONICO E TIMELESS TIME : PER UNA PERMANENZA TEMPORANEA
2018
Com’è avvenuto per le precedenti rivoluzioni industriali, la digitalizzazione non ha sortito effetti soltanto nei processi e nei prodotti tecnologici. Tra le sue dirompenti conseguenze sulla società e sugli individui, l’emergere di una diversa concezione del Tempo sta già condizionando il campo operativo e soprattutto teoretico dell’ambiente costruito connotato da significati culturali. Inusitate forme di memoria mettono in crisi la visione tradizionale di patrimonio, fondata su una visione lineare del tempo che separa nettamente il Passato dal Futuro, lasciando al Presente un mero ruolo da passatore. Superata la presunta immutabilità, ambizione di ormai obsoleti obiettivi conservativi rigi…
