The fifth annual meeting of Experimental Archaeology in Denmark (EAD) took place from 7 to 9 November 2025. This event followed previous meetings held at Ribe Vikingecenter, Middelaldercenteret, Bork Vikingehavn, and Vikingeborgen Trelleborg. The meeting serves as an opportunity for researchers, students, craftspeople, and others interested in experimental archaeology to meet and exchange ideas.
This article presents a selection of case studies developed within the Erasmus+ project CoVHer –Computer-based Visualization of Architectural Cultural Heritage (2022–2025), alongside the underpinning methodological framework. The project focused on the digital reconstruction of architectural works that have been lost or were never built, addressing critical concerns regarding the scientific credibility, transparency, and educational value of such hypothetical reconstructions. Building on previous collaborations, including contributions to the DFG Research Network: Digital 3D Reconstructions as Tools of Architectural Historical Research (2018–2022), CoVHer further developed key concepts and best practices in the field. It aimed to establish a shared methodology and vocabulary for virtual 3D reconstructions, especially in cases where physical remains are absent. The project produced four main results: (1) a set of theoretical principles and operational guidelines (CoVHer Guidelines) for assessing the scientific quality of 3D reconstructions, structured around criteria such as constructive accuracy, source traceability, interoperability, and communicative effectiveness; (2) a series of 3D case-study reconstructions developed by partner institutions and evaluated according to these criteria, incorporating polygonal and mathematical modelling as well as virtual and mixed reality technologies; (3) the CoVHer Repository, an online platform designed to store and share scientifically validated reconstructions, complete with documentation and metadata structured using a CIDOC Conceptual Reference Model (CRM)-based ontology; and (4) the development of Open Educational Resources, including a Massive Open Online Course (MOOC) hosted by the University of Bologna and blended learning modules implemented across participating institutions. Through this integrated approach, CoVHer has contributed to defining standards and tools for scholarly reconstruction practices, promoting critical engagement with digital heritage, and enhancing educational strategies in architecture and historical studies. The project’s outcomes are intended to support researchers, educators, and cultural institutions in producing and disseminating credible, transparent, and reusable virtual reconstructions.
Building upon our previous work on underwater (UW) image colour restoration, this paper advances the self-adaptive colour calibration (SACC)pipeline, by introducing a systematic, reference-based quantitative evaluation. UWimagery is notoriously affected by wavelength-dependent light absorption, scattering, and colour attenuation; these factors distort the visual appearance of submerged objects and complicate scientific documentation. Traditional model-based correction techniques often rely on well-calibrated equipment or prior environmental data; many artificial intelligence (AI)-driven approaches suffer from dataset bias and limited generalisability. The work explained below addresses these challenges by providing a flexible pipeline that restores colours without requiring extensive environmental metadata; this methodology is particularly well-suited for archival and in-field datasets. New datasets acquired from the 18th-century Nissia shipwreck site, located off Protaras in Cyprus, were employed to evaluate the pipeline under real-world excavation conditions. These datasets, captured with a rigid camera–strobe configuration, include reference regions with colour charts; these provide reliable ‘ground-truth’(GT)values for objective comparison. Structure from Motion (SfM) and Multi-View Stereo (MVS) were used to derive depth maps, which, together with red-green-blue (RGB)values, were input to a Feedforward Neural Network (FNN). The network was trained using Adam and RMSprop optimisers, enabling the restoration of perceptually accurate colours across varying conditions. Three metrics, modified R², Euclidean Distance, and the D metric, were applied to assess performance. The evaluation is constrained by the limited number of images containing colour charts; even so, this limitation reflects authentic field conditions, where divers must prioritise site documentation over calibration. Overall, this study validates the robustness of the SACC pipeline and introduces a replicable framework for evaluating UW image colour restoration. Beyond methodological advances, the findings highlight the potential of the pipeline to support cultural heritage documentation, archaeological interpretation, and long-term preservation of submerged sites.
Eimeriosis is a major problem affecting ruminants worldwide. The disease is primarilycaused by Eimeriaspecies, whichare specialized for each host and grow in the small and large intestine of animals. The losses due to subclinical infections (especially weight loss) and clinical disease (diarrhea) make the species of this genus a very significant economic concern. Therefore, this study was conducted in some areas of Wasit Province. A total of 180fecal samples fromgoats, of both sexes and covering different age groups and months, were collected. All fecal samples were examined microscopically, and 75 positive fecal samples were taken for molecular examinationand further analyzed using conventional PCR, sequencing and phylogenetic analysis. Microscopic results showed that the overall infection rate was 41.6%. The incidence of Eimeriaspecies ranged from 5.55% to 22.22% across three different species of the genus Emeria Schneider, 1875, namely E. arloingi(Marotel, 1905), Martin, 1909 (22.22%), E. christenseniLevine, Ivens & Fritz, 1962 (13.88%), andE. hirciChevalier, 1966(5.55%). Regarding the PCR reaction, results from the 18S rRNA, COI gene and genetic sequencing, Confirmed that the fecal samples were positive for EimeriaSchneider, 1875 species.

This article explores how the topics of fishing and urban development are addressed in a Vietnamese social history museum. Drawing on a project taking place in the Museum of Danang, it describes the way the museum represented the voices of a displaced fishing community who were moved from traditional fishing huts on the riverside to a social housing complex as part of Danang’s urban development plan in the 2000s. Capturing the impact of the community’s relocation on their fishing livelihoods through an exhibition of objects, photographs and texts, the article reveals ways in which nostalgia is recruited to make social, political and moral commentary on urban equality and livelihood change in a rapidly developing city. Methodologically, the project explored the limits of critical representation in an authoritarian state and how nostalgia can be understood as a subtle call for ethical action.
Beeswax is a frequently mentioned binder additive in the literature. Unfortunately, it is not so durable as to be well preserved in archaeological records, although there are faint exceptions. Because of its strengthening capabilities, which is believed to be its role, this research set out to carry out an experiment to verify the effects of adding it to the adhesives potentially used in the European Stone Age. The study used pine resin and its various compositions with beeswax and frequently used charcoal. The binders obtained were then compared with birch tar, which is considered to be one of the best adhesives in prehistory. Arrow ballistics were used to verify the effectiveness of beeswax addition, which shows that this addition has a high-quality effect on the natural binders.

Durante o tratamento de feridas, profissionais de enfermagem precisam consultar várias informações para decidirem o que fazer e precisam registrar as informações produzidas. Este trabalho relata uma investigação sobre as necessidades informacionais de profissionais de enfermagem durante o tratamento de feridas. Foi aplicado um questionário com 14 perguntas para 50 participantes de um curso de Terapia Larval, um tipo de tratamento de feridas. O questionário abordava o perfil dos participantes e suas necessidades informacionais. Após a análise descritiva individual dos dados coletados em cada pergunta, analisou-se possíveis relações entre algumas respostas para verificar a influência do perfil do participante sobre sua necessidade informacional. Identificou-se informações importantes sobre o paciente, suas feridas, fontes de informação utilizadas, modos de registro de informações produzidas durante os atendimentos, e sobre os tipos de apoio informacional que um software poderia oferecer para apoiar o tratamento de feridas. Uma melhor compreensão das necessidades informacionais durante o tratamento serve de insumo para o oferecimento de um melhor suporte informacional aos profissionais e pacientes envolvidos.

In the 1970s, the world knew the long-tailed nesokia Nesokiabunnii(Khajuria, 1981) (Rodentia, Muridae) from the Mesopotamian marshes of Garden of Eden in Southern Iraq. This distinct rodent was known from only five voucher specimens collected at the confluence of Tigris and Euphrates Rivers in southern Iraq while its occurrence in Southwestern Iran had neverbeen reported. In the 1990s, a large extent of its natural habitat was catastrophically
636First photographic recordsdesiccated and the animal was last seen in the 1970s. Since then, the status of this elusive rodent was shrouded in mystery. In 2007, an extraordinary photograph of a carcass of this species came to the light from Hawizeh Marsh which was interpreted as concrete evidence of the species’ persistence in the marshes of southern Iraq after the desiccation in the last century. In 2021, after more than 40 years, exclusive photographic records of living N.bunniiwere obtained for the first time from Central Marshes in southern Iraq and from Edhe’am Marsh in southwestern Iran. The new distribution range is highlighted in this note. Furthermore, the first photographs of living N.bunniiare provided along with notes on its ecology and behavior.

Un vaso recientemente adquirido por el Estado para el Museo Arqueológico Nacional, un ánfora apulia de figuras rojas del Pintor de Baltimore, fechada entre 330 y 320 a. C., nos permite realizar, a través de la lectura de sus imágenes, un recorrido por los paisajes infernales y paradisíacos del imaginario suritálico. El programa iconográfico e ideológico de este vaso, decorado con una escena de naiskos, una escena con personajes junto a una estela funeraria y una escena con la visita de Orfeo a los Infiernos, incide en un mensaje claramente salvífico, ofreciendo la promesa para los difuntos de una nueva existencia, edénica e inmortal, más allá de la muerte.

Sammendrag
I 1871 vedtok Stortinget å tillate etableringen av brennevinssamlag,
i form av private aksjeselskaper som kunne få ansvaret for skjenkingen
og omsetningen av alkohol i norske byer. Ifølge loven skulle overskuddet
fra disse selskapene gå til allmennyttige formål i kommunen. Dette
bidro til å skape en nær forbindelse mellom alkohol- og kulturpolitikk
på siste del av 1800-tallet, da norske kulturinstitusjoner ble mottaker
av betydelige summer fra brennevinsprofitt.
Denne artikkelen analyserer Trondhjems Brændevinsamlags bevilgninger
til Trondhjems Kunstforening og Nordenfjeldske Kunstindustrimuseum
i perioden 1891 til 1904. Gjennom en undersøkelse av samlagets privatarkiv
drøfter jeg hvorfor brennevinsprofitt ble kanalisert inn i trøndersk
kulturliv, hvordan pengene ble anvendt, samt hvilke konsekvenser
tilskuddene fikk for disse to institusjonenes virksomhet. Formålet
med artikkelen er å fremheve betydningen av privat finansiering
av norsk museumsvesen i et historisk perspektiv.

Over the past few years, beekeeping has been a media focal point. Nevertheless There is a paucity of knowledge surrounding the prehistory of beekeeping outside of the information from the east and south Mediterranean regions. The author is an archaeologist and a beekeeper and commenced this project in 2016, having given presentations and submitted articles to a German beekeeping magazine (Guber 2016) and conducting research of “archaeobeekeeping” within archaeological contexts.
O presente estudo tem como objectivo essencial lançar um novo olhar sobre as quase ignotas pinturas que actualmente
decoram os altares laterais da igreja de S. Francisco de Tomar, oriundas da capela-mor da igreja do extinto Convento
de Nossa Senhora da Soledade das Trinas do Mocambo, de Lisboa. Dedicadas a temas marianos, a nossa proposta
de datação situa a sua feitura no segundo quartel do século XVIII (c.1730-40) e cremo-las tributáveis a um dos
sequazes do fa presto Bento Coelho da Silveira. A análise pictórica das mesmas revela, contudo, um pintor mais
evoluído compositivamente, já liberto do penumbrismo seiscentista e aberto às novas influências ítalo-francesas,
nomeadamente de Simon Vouet, Chaperon e Maratti.

This article introduces an important group of ethnographic, biological, and unpublished archival materials deriving from two expeditions to Madagascar by American naturalist William Louis Abbott (1860–1936). The first was from February to September 1890; the second from January to July 1895 when Abbott rushed back to Madagascar not only to collect for the Smithsonian but also to join the Merina in their unsuccessful war of independence against the encroaching French government. Beyond summarizing localities he visited and the current organization and usefulness of his collections for research, the article attempts to interpret archival records to assess Abbott's collecting focus, biases, and purposes; his perspectives on contemporaneous events in Madagascar; and also the role that “naturalist” collectors such as Abbott played within the history of anthropology and of museums. Ethnographic information is embedded not only within the ethnographic collections but also within associated biological collections and archives.

The Great War (1914–1919) forced society to decide whether cultural heritage institutions, as a whole, had value. An examination of the types of materials gathered during the Great War, the identity of the collectors, and the intended purpose the repositories highlights the shift in the methodological practices of libraries, archives, and museums during this period. This study focuses primarily on three Allied museums created during the conflict: The Imperial War Museum in England, the Bibliothèque-Musée de La Guerre in France, and the Liberty Memorial in the United States. These institutions emphasize how types of repositories were used as they instituted contemporary collecting practices to further education, to create community-based collections for increased public understanding, and to create a social memory about the Great War.
