Conservation and Restoration OpenLab
Open laboratories (OpenLabs) in Cultural Heritage institutions are an effective way to provide visibility into the behind-the-scenes processes and promote documentation data collected and produced by domain specialists. Cultural Heritage (CH) institutions have been adopting new practices to improve their services and meet the preferences and needs of potential audiences. One such practice is the transformation of conservation and restoration (CnR) laboratories into OpenLabs, which allow visitors to see the various processes that take place “behind the scenes” .

Muntanya Assolada
Muntanya Assolada is a Bronze Age settlement located on the right bank of the Xúquer river, in Spain, built on the top of a spur of the Corbera mountain range, dominating the river plain from a height of 227 metres (745 ft) above sea level. It is located in the municipality of Alzira, Valencia, Spain. Excavation campaigns began in 1978, under the direction of Bernat Martí Oliver, and continued until 1996, and work on the site was resumed in 2004. From the 1990s Rosa Enguix Alemany and María Jesús de Pedro joined the direction of the site. At present the excavated area covers 700 square metres (7,500 sq ft) and includes different structures, like a central street and rectangular departments on both sides; a wall of two meters wide that preserves almost three meters of height (6.6 × 9.8 ft); occupancy soils and abandonment episodes; livestock stabling; and terracing of the slopes to expand its surface. At present the site is property of the Alzira City council, and the new beginning of the excavations by the Servei d'Investigació Prehistòrica has as objective the consolidation of the exhumed structures and its signposting for visitor access. A nearby burial cave indicates the continuity in the use of natural caves as necropolis, and an individual burial has been found in a pit in the interior of the area too. On the other hand, the recovered remains show a wide chronological sequence between the Early Bronze and the Late Bronze.

Drone Photogrammetry for Underwater Cutural Heritage Documentation
Underwater cultural heritage (UCH) is an irreplaceable resource with intrinsic value that requires preservation, documentation, and safeguarding. Documentation is fundamental to increasing UCH resilience, providing a basis for monitoring, conservation, and management. Advanced UCH documentation and virtualization technologies are increasingly important for dissemination and visualization purposes, domain expert study, replica reproduction, degradation monitoring, and all other outcomes after a metric survey of cultural heritage (CH). Among the different metric documentation techniques, underwater photogrammetry is the most widely used for UCH documentation. It is a non-destructive and relatively inexpensive method that can produce high-resolution 3D models and 2D orthomosaics of underwater sites and artifacts. However, underwater photogrammetry is challenged by the different optical properties of water, light penetration, visibility and suspension, radiometric issues, and environmental drawbacks that make underwater documentation difficult.

Stable Isotopes Rationale for Tell Humeida
The techniques of agriculture and animal husbandry at Tell Humeida, a Middle Uruk Period (Late Chalcolithic) site on the middle Syrian Euphrates, were studied using stable isotopes of bone collagen of domestic and wild mammals and from cereal and ruderal plant seeds.

Kandake: Nubian Women Rulers
Kandake is the Meroitic word for “queen”; however, it does not necessarily signify a sole ruling monarch. The role of kandake is not only the female counterpart of the king but a complementary dual player in Kushite rulership. In comparison to ancient Egyptian queens, Nubian female rulers are underrepresented in the field of Egyptology. Iconographic and funerary evidence in the archaeological record shows that these women held power and status equal to Nubian and Egyptian kings and could be considered a model for sole female rulership in the ancient world.

Defining Imitative Coinage in the Roman Imperial Period on the Territory of the Empire
Imitative coinage is understood to be any currency issued outside of the official known coin series. This currency could have been issued by individuals or state agents, and its main function was not profit, but rather it responded to currency shortages and acted as a currency of necessity. It must be distinguished from the currency itself, which had a lucrative intent on the part of the issuers. Coin imitation was a phenomenon that occurred during various chronological periods throughout the Roman Imperial era, essentially linked to historical events that caused a monetary shortage. This refers to a phenomenon where coinage not issued by the official authority was introduced into circulation and utilized in commercial exchanges of various kinds, a fact that can be demonstrated archaeologically. Imitative coinage can be detected through detailed numismatic studies, revealing variability in stylistic elements, as well as physical characteristics (such as weight or diameter) when compared to the official issue. Coin imitation should not be confused with monetary counterfeiting, as its intention was not to profit the unofficial issuer, but rather to facilitate daily commercial exchanges. Even so, the characteristics of both can be similar in some cases, which can make it difficult to assign them to one type or the other. The imitative pieces, primarily in bronze types though not limited to them, played a highly significant role in maintaining Roman economic systems during periods of decline in official currency.
