Natural products obtained from plants with biocidal activity represent an alternative and useful source in the control of biodeterioration of documentary heritage, without negative environmental and human impacts. In this work, we studied the antimicrobial activity of seven essential oils against microorganisms associated with the biodeterioration of documentary heritage. The essential oils were obtained by steam distillation. The antimicrobial activity was analyzed using the agar diffusion method against 4 strains of fungi and 6 bacterial strains isolated from repositories air and documents of the National Archive of the Republic of Cuba and the Historical Archive of the Museum of La Plata, Argentina. Anise and garlic oils showed the best antifungal activity at all concentrations studied, while oregano oil not only was effective against fungi tested but also prevented sporulation of them all. Orange sweet and laurel oils were ineffective against fungi. Clove, garlic, and oregano oils showed the highest antibacterial activity at 25% against Enterobacter agglomerans and Streptomyces sp., while only clove and oregano oils were effective against Bacillus sp. at all concentrations studied. This study has an important implication for the possible use of the natural products from plants in the control of biodeterioration of documentary heritage.

Burkina Faso and Mali have been grappling with multiple security threats including jihadist challenge, military coup d'état, violent extremism, and poor governance. These complex security problems have escalated into national conflicts, state failure, internal displacements, and forced migration. This paper examined the changing patterns of the drivers and enablers of these security threats and how these forces feed into the protracted challenges of forced migration and population displacements.

Stephan Schätzl was the parish priest of Viechtwang, Upper Austria. He lived in the aftermath of the Peace of Augsburg in a period of schism between Roman Catholics and Lutherans. His portrait, depicted only 6 days before his demise in 1590, shows that he had extreme ante mortem cachexia.

Background: The article presents, from a diachronic perspective, the concerns of valorization and preservation of the documentary heritage through digitisation projects in the Romanian Library System. The development of the argument is made starting from the analysis of the interest in the subject in international literature (through a bibliometric analysis) and the investigation of the online presence of libraries expressed statistically from the typology of forms of representation, to specific digital products and services, thus highlighting how they evolved in the sense of diversifying and modernizing the products and services provided and taking into account the political, economic, and technological constraints.
Methods: The evaluation of the involvement of Romanian libraries in digitisation activities was done through the such research methods as content analysis and scientometric research, which allowed the carrying out of a longitudinal case study extended for the period 2007-2022, during the unravelling of the events.

Over the recent period, there has been an increasing interest in the use of pulsed infrared thermography (PT) for the non-destructive evaluation of Cultural Heritage (CH). Unlike other techniques that are commonly employed in the same field, PT enables the depth-resolved detection of different kinds of subsurface features, thus providing helpful information for both scholars and restorers. Due to this reason, several research activities are currently underway to further improve the PT effectiveness.
