The study concerns Italian masonries and focuses on historical, medieval and modern mortars. Within the context of the different regions under examination (Piedmont, the Po Valley area, Latium, the Umbria-Marche region, and Apulia and Sardinia) a wide variety of materials with different chemical-physical characteristics were used in masonry work, determining different structural behaviors. The project aims at improving our knowledge about historical mortars in order to further the conservation of Italian built heritage, especially in zones with seismic risk. To achieve these results, we took samples and carried out analyses to investigate the different mechanical and cohesion properties that influence the vulnerability of ruined or collapsed structures. This information has enabled advances to be made in the prevention, maintenance, protection and preservation of historical buildings. Further details will concern the history of construction techniques, with particular regard to the relationship between local resources and construction sites. Another important topic is the role of different components and additives during the preparation of the mortars and their level of hydraulicity.

The research paper discusses the problem of distorting the body proportions in Ramses II statues during the inadequate restoration operations carried out in the 21st century in Egypt. It also discusses the correct artistic body proportions and formation of Ramses II, which must be followed when assembling and restoring statues depicting this figure, at the same time taking into consideration other, unrestored statues, reliefs and paintings of the same subject. In addition, it looks at global restoration technologies that can help to solve the problem of improper restoration in Egypt.

Albumen, silver gelatin and chromogenic prints are found abundantly among photographic collections in Egypt. Due to the uncontrolled environment in archives and libraries, this precious visual heritage with its high protein and cellulose content provides the right culture medium required for fungal growth. Many essential oils have been proven to have antibacterial and antifungal properties. Essential oils offer a safe alternative to other common disinfection methods; however, their effect on the properties of photographs have not received much study. This paper studies the effect of vapors of anise, cinnamon, clove, lavender and thyme oils on albumen, silver gelatin and chromogenic prints, to find a proper disinfection method that is user-friendly and environmentally safe and respects the nature of photographic materials. Essential oils were provided by the National Research Center (NRC) in Cairo, Egypt. Artificially aged albumen prints, and naturally aged silver gelatin and chromogenic prints were exposed in desiccators to the selected essential oils in the vapor phase for a period of 5 days. All samples were artificially aged at a temperature of 80°C and 65% RH for a period of 5 days to study the long-term effects of the tested treatments. Treatments were evaluated using several techniques including visual inspection, microscopic inspection, colorimetric measurements, and attenuated total reflectance Fourier transform infrared spectroscopy. Results showed that all tested essential oils had a very slight effect on the tested photographic samples; however lavender oil was found to be the best option, specifically in terms of preserving the chemical properties of the photographic surfaces.

The osteological investigation of archived and historic skeletal collections can often provide clues to how they were organised and managed, offering key osteobiographical insight into past populations. A small, yet significant, collection of skulls housed at the Museum “Giuseppe Sergi” of the Sapienza University of Rome, remained anonymous prior to a recent reassessment protocol started in 2018. This collection was excavated from a funerary area discovered during the 19th century from the site of Castel Trosino (Ascoli Piceno, Italy). The cemetery was part of an important community during the Longobard domination of Italy, as testified by the richness of the cultural artefacts reported with the burials. The 19 skulls presented in this paper are the only ones available for assessment; all the others were lost shortly after the first excavation. Their importance is related to providing a better understanding of biological evidence of a community that lived in Italy during the Early Middle Ages.

This article presents the findings from a two-year study of the Last Supper canvas in the Abbey of Tongerlo, Belgium, including a detailed review of its provenance as well as a multispectral study conducted by IMEC and IPARC. The study used a composite multidisciplinary approach, with traditional connoisseurship and literary research augmented by scientific examination, including IRR (Infrared Reflectography). The article argues that based on the available evidence, the Tongerlo Last Supper was produced in Leonardo’s Milanese workshop between 1507 and 1509, as a collaborative project involving the Leonardeschi Giampietrino, Andrea Solario, and Marco d’Oggiono under Leonardo’s supervision. Furthermore, the infrared spectography scans suggest that the face of John in the painting was painted by Leonardo himself.

Architectural heritage surveying plays a fundamental role in the preservation of historic buildings for scientific research, education and tourism. The use of Unmanned Aerial Vehicles and Terrestrial Laser Scanning techniques are essential for architectural heritage surveying and mapping. In recent years, the combination of Building Information Modelling (BIM) with heritage studies has been presented as Historic BIM (HBIM) which, integrated with UVA and TLS, is a technique that is able to deal more efficiently with the management and protection of historic buildings. This paper focuses on the integration of UVA images and point clouds from laser scanning to build a 3D architectural model for the documentation of Chinese historic buildings. In particular, the method, tested in the case study of the traditional village, Hexinwu, China, can contribute further to the analysis, evaluation and heritage planning of this remarkable architectural structure, thus increasing its historical significance for the future.

Tourists’ interest in traveling to Lahore (more specifically to the Badshahi Mosque and the Royal fort) has increased in recent years and is expected to continue. Despite this, very few facts are known about an individual's attitude towards cultural heritage. This study looks at the pre- and post- visit factors that encourage tourists to come to the cultural heritage sites and also identifies variables that help to estimate their willingness to pay (WTP) for admission to visit them. The data from 200 tourists was collected through a well-prepared questionnaire and then used in the final analysis. The contingent valuation method (CVM), considered to be the most useful, with a dichotomous choice question, was used to estimate the WTP. Two models were used in estimating the WTP, i.e. binary regression and ordinary least squares (OLS). The findings acknowledged that tourists were interested in retaining happy memories, experiences and knowledge through the visit. More than 75% of the tourists were willing to pay for cultural heritage, had a positive attitude toward it and would like to visit these destinations again. Tourists’ income was a positive and significant determiner of WTP; the total cost of the visit and environmental issues were negatively related to WTP. As tourism provides an important source of income, the findings of this study point to some practical recommendations that may be implemented in the future by local authorities.

The aim of this study is to highlight the appearance of deterioration resulting from weathering effects on the beech wood used in the ornamentation of wooden window grilles (Mashrabiya) in the Mosque of Prince Hassan, in Akhmim-Sohag and in the Mosque of Khawand Asalbay, in Fayoum, Egypt. This wood was accurately examined with a Digital microscope and Scanning Electron Microscope (SEM) to diagnose the deterioration processes on the surface of the wood. Fourier transform infrared (FTIR) was used to identify the changes in the main components of the beech wood resulting from weathering factors. The chromatic change of the beech wood surface was measured by spectrophotometer and the results were calculated by using the CIE-L*a*b* system. Results showed the physical and chemical changes that had occurred in the degraded beech wood. The results helped to develop a treatment plan using already experimented materials that do not harm the wooden artifacts.
