Two operative risk indicators as tools for negotiating contracts between curators of Museums and HVAC technical services providers

2020

Abstract The purpose of Heating, Ventilating and Air-Conditioning (HVAC) systems in museums is to properly control important microclimate parameters; such systems, in fact, apart from ensuring the visitors’ wellbeing, are requested to guarantee suitable indoor conditions for the proper conservation of the important cultural goods hosted by museums. Hence, in case of disservice, or interruption due to maintenance interventions, it is important to quantify the economic damage induced to exhibited and/or stored works of art (or even to the building museum itself). Accordingly, it is essential to guarantee the shortest possible period of disservice during which probable damages for the works of…

The Distribution and Chronology of Trading Equipment in Present-Day Latvia in the Tenth to Thirteenth Centuries

2017

This article brings together the main research findings of recent years relating to tenth to thirteenth-century trading equipment from present-day Latvia. Finds of collapsible scales and weights from all regions of Latvia have been mapped and investigated. These include finds from archaeological sites in the Zemgale and Kurzeme regions that have previously not been extensively analysed. Issues relating to the chronology of the scales and weights are discussed. The main trade routes and the dynamics of trade contacts are determined, based on the distribution of the material in different regions. Key words: trade routes, chronology, scales, weights.

Regional inequality and economic development in Spain, 1860–2010

2016

Abstract Fifty years ago Jeffrey G. Williamson suggested that during the process of economic development regional income differences trace out an inverted U-shaped pattern. Since then several studies have tested this hypothesis. Yet, most of these only explore particular stages of development. This study, however, investigates the long-term evolution of regional income inequality. Using a novel dataset spanning 150 years, we describe per-capita GDP disparities across Spanish provinces (NUTS3) from 1860 to 2010. Moreover, to gain a deeper understanding of regional inequality, we examine other relevant dimensions: modality, mobility and spatial clustering. Overall, the findings confirm the ex…

Julien : les années parisiennes

2009

This article intends to scrutinize in what ways Julian’s stay in Gaul as a Caesar were decisive in Julian’s political and military education, and whether a specific ruling style and manner may be detected in the Parisian years of Julian’s government. Relying on a critical analysis of the documentation (Julian himself, Mamertinus, Ammianus, Libanios), the author examines the military and civilian aspects of Julian’s training as an apparently inexperienced ruler but quick learner. She carries out a prosopographical study of the Caesar’s circle and the administrative staff which was then on duty, combining friendly and hostile persons. Gaul offered him a training ground and he became even the …

A Late Roman industrial complex with glass furnaces in the northern area of Valencia

2008

Abstract Information from excavations in Conde de Trenor street (1997) and Cisneros square (1986 and 1998) has confirmed that this area situated in the north of Valencia was a river port district dedicated to commercial activities and storing goods during the Roman Imperial period and maybe also in the Republican period. At the end of the third century A.D. the function of these port buildings changed and the evidence suggests that they became industrial workshops. The bases of three circular furnaces were found with fragments of glass containers, bottles, glasses, window panes and some slag. The recent excavation which took place in 2004–2006 in the Palau Cervero , 4 Cisneros square also s…

HISPANIC HOARDS FROM ALVARELHOS TO TOMARES: A HISTORICAL REVIEW

2020

With this contribution we would like offer a first and brief approximation about the Hispanic Coin Hoards, roughly dated between the reigns of Augustus and the end of the Tetrarchy. We will focus solely on the imperial hoards found in the Iberian Peninsula. In a chained, diachronic and casuistic way, we offer an analysis according to a series of variables: historical events, archaeological context, pattern of hoarding and functionality. For the data collection, in the present chapter we do not intend to be exhaustive. We will cite the most outstanding examples of Hispanic-Roman Hoarding, in order to understanding the historical-economic evolution from Iberian Peninsula.With this contributio…

Different methods for soluble salt removal tested on late-Roman cooking ware from a submarine excavation at the island of Pantelleria (Sicily, Italy)

2014

Abstract This paper deals with the comparative evaluation of different procedures of salt extraction designed for archaeological ceramics from submarine burial environments. The experimental work was carried out on a particular type of late-Roman cooking ware finds (Pantellerian ware) found in a shipwreck near the shoreline of the Island of Pantelleria (Sicily). The studied ceramic test-pieces were first recognised in terms of bulk characteristics (mineralogy, petrography and chemistry). SEM-EDS observation allowed verification of the presence of various secondary minerals at the surface and in the pore spaces formed after the prolonged permanence in seawater under oxidising or reducing con…

Consolidation and protection by nanolime: recent advances for the conservation of the graffiti, Carceri dello Steri Palermo and of the 18th century l…

2014

Abstract Nanolime dispersed in 2-propanol was extensively used for the consolidation of wall paintings. The knowledge of the advances of this methodology dealing with all the possible effects associated with the nanolime new material in conservation is fundamental to assess and improve the technique. In this paper, four different dispersions of Ca(OH) 2 nanoparticles were characterised by Small Angle X-rays Scattering technique (SAXS) and Transmission Electron Microscopy (TEM) in order to achieve information on size, shape, polydispersity, agglomeration, and crystal structure (by SAED patterns) of the particles. Once characterised, the dispersions were tested in two different case studies, …

Characterization of Iranian Moarraque glazes by light microscopy, SEM-EDX and voltammetry of microparticles

2008

Abstract Glazed ceramics have been traditionally used in Iran for decorating mosques and some civil historical buildings. In particular, Moarraque glazes have been extensively used in the indoor and outdoor decoration of mosques in Iran since the middle 14th century. The pieces have a complex elaboration based on a main glazed piece corresponding to the skeleton structure of the Shah Abbasi flower, which contains a number of holes, where are placed, mosaic-like, smaller glazed pieces forming a compact and single tile. The present work describes the analytical study performed on the glazes of several pieces of Moarraque tiles from the Ali Ebn Abi Taleb Mosque (Esfahan, Iran), which date back…
