<p>The monitoring of environmental corrosivity around works of cultural heritage is a key task in the field of both active and preventive conservation. In the case of metallic artworks, this task can be performed by means of coupons or sensors realised with the same materials as the artworks to be conserved. In this work, a measurement system for the development and testing of sensors for atmospheric corrosivity monitoring is presented. The metrological features of the measurement system operated in conjunction with a developed sensor are analysed. The sensor allows for considering the different corrosion behaviours due to the presence of corrosion layers on the object to be preserved. The first developed sensors are made of pre-corroded copper and their resistance is measured. The developed system allows for monitoring thickness loss of over 3 nm in the temperature range of 23 °C – 39 °C. The performed analysis demonstrated that the system presents an efficient laboratory setup for the development and characterisation of sensors for atmospheric corrosivity monitoring.</p><div> </div>

Systematic research into art and cultural heritage objects in museum collections are growing daily across the world. They are generally undertaken in partnership with archaeologists, curators, historians, conservators, and restorers. The use of scientific methods to answer specific questions about objects produced by different societies reveals the materials and technologies used in the past and gives us a better understanding of the history of migration processes, cultural characteristics, and thereby more grounded parameters for the preservation and conservation of cultural heritage. The use of non-destructive methods, such as the PIXE analysis, is very suitable in such studies because damage or alteration is avoided and the integrity of the object maintained. Such techniques gave historians and curators at the Archaeological and Ethnology Museum in São Paulo new understanding of the Chimu collection of ceramics as well as of the technical process of preventive conservation.

Abstract The article presents the analysis of metrological properties of a two-current-source supplied circuit. It includes such data as precise and simplified equations for two circuit output voltages in the function of relative resistance increments of sensors. Moreover, graphs showing nonlinearity coefficients of both output voltages for two resistance increments varying widely are presented. Graphs of transfer resistances, depending on relative increments of sensors resistance were also created. The article also contains a description of bridge-based circuit realization with the use of a computer and a data acquisition (DAQ) card. Laboratory measurement of the difference and sum of relative resistance increments of two resistance decade boxes were carried out indirectly with the use of the created measurement system. Measurement errors were calculated and included in the article, as well.

The Canadian Conservation Institute (CCI) has developed a Geographic Information System (GIS) of hazards for Canadian cultural heritage institutions. The greatly increased access to open data is changing how advisory bodies like the CCI and the public can access and share information. For the purpose of investigating how a GIS approach can assist the CCI with its mandate to improve the preservation of collections, a map layer of cultural heritage institutions across Canada has been assembled and continues to be upgraded for accuracy, inclusion and detail (Fig. 1). This was combined with a collation of hazard layers; a partial list includes: seismic risk, notably expectations of earthquake severity tied to improvements in the national building code, tsunami exposure, wildfire data, hurricane, tornado, lightning density, pest distribution, and energy use indicators such as heating degree days and climate norm data. The platform allows examination of expectations around climate change driven risks such as sea-level rise, storm-incursions, permafrost melt. The GIS approach will also allow reassessments around expected changes to flood risk maps issued by jurisdictions, as well as Statistics Canada layers on population related factors such as changes in numbers of local populations, income and demographic shifts which can be stressors or opportunities. Sources have been drawn from federal, provincial, municipal, and academic evaluations of hazards, which now are more commonly published as GIS products. Mapping Canadian heritage institution's within a GIS improves our ability to: visualise and interpret to clients the relative magnitude of their local hazards, make ties to more refined local analyses, and show adjacencies to mapped historical events. From a national perspective the GIS can generate profiles of aggregated institutional exposure to the hazards, and more readily identify sub-populations of institutions for which particular risks would rank higher or lower among their concerns. This improves CCI's preventive conservation advisory service's perspective on mappable risks for any institution we deal with as clients. Ultimately, through federal initiatives in open data, it is our intention that client groups can look at the GIS for the purpose of educating themselves on hazards they would want to prepare for.
