X-ray Computed Tomography (X-ray CT) is a sophisticated non-destructive imaging technique to investigate structures and materials of complex objects, its application can answer many conservation restoration questions. However, for Cultural Heritage investigations, medical CT scanners are not optimized case-studies: These instruments designed the human body, flexible difficult use in situ. To overcome these limitations safely works art on site—in laboratory or museum—the Laboratory University...
Detectors are a key feature of the contemporary scientific approach to cultural heritage (CH), both for diagnostics and conservation. INFN-CHNet is network Italian National Institute Nuclear Physics that develops applies new instrumentation study CH. This process results in optimized traditional state-of-the-art highly innovative detection setups spectrometric techniques. Examples former X-rays, gamma-rays, visible-light particles spectrometers tailored CH applications, with performances,...
The internal structures and the hygroscopicity of bio-based boards consisting giant reed (Arundo donax L.) hazelnut shells as bio-aggregates, a sodium silicate solution adhesive, were investigated. aim was to evaluate influence each material (the bio-aggregates adhesive) their distributions in on final performance. By carrying out X-ray computed tomography, porosities determined, allowing important considerations hygroscopicity. voids’ percentages between 26% 36% total volume composites....
The diagnosis of tuberculosis (TB) in osteoarcheological series relies on the identification osseous lesions caused by disease. study identified skeletal collections provides opportunity to investigate distribution relation this aim was examine evidence for TB late adolescent and adult individuals from human collection Certosa cemetery Bologna (Italy, 19th-20th c.). sample group consists 244 (138 males, 106 females) ranging 17 88 years age. divided into three groups basis recorded cause...
The northern Adriatic continental shelf hosts several coralligenous reefs rising from the sedimentary bottom and characterized by three main benthic assemblages, respectively, dominated algal turfs, encrusting calcareous rhodophyte (ECRs) or erect sponges. Bioconstruction bioerosion processes have been investigated using recruitment travertine limestone tiles deployed in a random site for each assemblages off Chioggia, 6.1–14.4 km offshore 20.2–25.4 m depth. Tiles were retrieved after 3 12...
In this paper, we describe the work done in order to run CT 3-D reconstruction algorithm on 120 GB raw data from more than 25\thinspace000 radiographs acquired Kongo Rikishi (XIII century) Japanese wooden statue. The was using Microsoft (Redmond) HPC cluster and then a local at INFN of Bologna. A speed-up factor 75 reached.
Abstract Scientific investigations of artworks are crucial in terms preservation since they provide a measurable evaluation the materials and state conservation. This is case Antonello da Messina’s painting “Ecce Homo”: its delicate conservation, with need for constant monitoring, required broad in-depth diagnostic campaign to support restorers. The project was carried out entirely situ using non-invasive cutting-edge techniques proposes multimodal data-centric approach, integrating 3D 2D...
Abstract Objectives During the middle‐to‐upper Paleolithic transition (50,000 and 40,000 years ago), interaction between Neanderthals Homo sapiens varied across Europe. In southern Italy, association fossils non‐Mousterian material culture, as well mode tempo of Neanderthal demise, are still vividly debated. this research, we focus on study two human teeth by using 3D geometric morphometric approaches for a reliable taxonomical attribution obtaining new radiometric dates archeological...
The diagnostic investigations are an important resource in the studies on Cultural Heritage to enhance knowledge execution techniques, materials and conservation status of a work art. In this field, due great historical artistic value objects, preservation is main concern; for reason, new technological equipment has been designed developed Physics Departments Universities Ferrara Bologna non-invasive approach study pictorial artworks other objects cultural interest. Infrared (IR)...
Novel bio-imaging techniques such as micro-Computed Tomography provide an opportunity to investigate animal anatomy and morphology by overcoming limitations imposed traditional anatomical drawings. The primate genital bones are complex structures whose occurrence in both male penis (baculum) female clitoris (baubellum) may be difficult assess individual cadavers. We tested a 3-step methodological protocol, including different ranging from inexpensive/simple more expensive/sophisticated ones,...
An isolated human cranium, dated to the early Eneolithic period, was discovered in 2015 at top of a vertical shaft natural Marcel Loubens gypsum Cave (Bologna area, northern Italy). No other anthropological or archaeological remains were found inside cave. In caves same area anthropic and funerary use are attested from prehistory more recent periods. We focused on investigating circumstances surrounding death this individual, since cranium shows signs some lesions that appear be results...
This study utilises X-ray Computed Micro-Tomography (μXCT) as a non-destructive and non-invasive method to recover the original surface features reveal characteristics of encrusted, illegible Roman copper-based coins before any physical cleaning process is performed. The were retrieved from topsoil during an archaeological survey in countryside ancient city Aquileia, Italy, severely degraded, covered with accumulated matter pronounced encrustations developed over centuries aging buried soil....
In this paper we introduce a calibration-free beam-hardening correction technique in computed tomography, which improves the results achieved by state-of-the-art method. Two main practical points are here underlined: (1) need to perform beam hardening without previous calibration; (2) consider shape of object all its whole three-dimensional extent. The proposed method requires: (a) first complete reconstruction means cone-beam filtered back projection algorithm; (b) segmentation...
