The first principle is called comparative observation with known positives and negatives. Examples include using microchemical spot testing, polarized light microscopy, and x-ray fluorescence (XRF) spectrometry. The second principle is defined as a preponderance of the evidence and will be illustrated through the characterization of indigenous and archaeological objects such as the Alaska Fur ID project and generation of a collections care “What’s That White Stuff” blog for small museums. The third principle is referred to as collaborative consensus, using examples of testing of adhesives for collections labeling, treatments of waterlogged archaeological basketry, and ongoing research about dyes used in Chilkat robes combining the expertise of a local group of weavers with GCMS analysis performed at Portland State University through the Pacific Northwest Conservation Science Consortium serving to highlight this concept.

These measurements may be used to determine the degree of stability of the metal artifacts for their long-term preservation. Based on the test results a conservation plan may be drafted according to three options: (1) active conservation intervention (e.g., treating with a chemical corrosion inhibitor or desalination); (2) preventive conservation through control of the environment; and (3) no protective measures necessary. Recommendations for conservators include simple tests on soil and representative artifacts as a guide to predict decay behavior for post-excavation collection management.

During a preservation needs assessment conducted by the Conservation Center for Art & Historic Artifacts (CCAHA), Museum staff pointed out tarnish and corrosion on the trophies in the memorabilia collection. This raised a number of questions, foremost being, “What should the museum do to slow down the deterioration of these metal objects?” The two institutions embarked on a collaborative research project aimed at answering this question. Existing literature supplied best practices, but the Museum wanted solutions specific to its needs and priorities. The Museum’s collections manager and CCAHA’s preventive conservation fellow worked together to investigate air quality on a modest budget and timeline. This case study explores the cost-effective and low-maintenance methods that were used to monitor environmental conditions, dust, acid off-gassing, and metal corrosion: dataloggers, sticky dust collectors, A-D Strips, and metal coupons. Evidence-based testing informed, educated, and initiated progress in collections care.

In industry, adhesive strength is often determined using standardized tests including 90° peel tests. However, not all conservation studios have or can afford mechanical testing equipment for such tests, although it is often readily accessible at third-party facilities. For a university conservation project, an international standard 90° peel test was modified to study the adhesive strength of consolidants for zinc white paints. Consolidants were applied to painting canvas strips, which were then adhered to zinc white paint layers on glass supports. The strips were peeled downward by continually adding fine sand to a cup attached to the end of the canvas strips. Video recordings were made of the continual loading and sudden stepwise extensions of the peeling samples, so that step-wise force - peel length curves could be plotted for each specimen. The data combined with examination of the peeled surfaces provided important qualitative information over strength and toughness (ductility/brittleness) for comparing the tested consolidant-zinc white systems. The adapted peel test is therefore a valuable method for testing adhesives and consolidants in the conservation studio. However, one must avoid overinterpreting the results, since consolidant selection depends on more factors than just mechanical properties.","PeriodicalId":17165,"journal":{"name":"Journal of the American Institute for Conservation","volume":"62 1","pages":"139 - 151"},"PeriodicalIF":0.5,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47593364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geometric variations between 3D models acquired with differing methods make metric conservation applications such as condition monitoring and measuring change over time challenging. This article presents an investigation of wavelength selection using a modified off-the-shelf DSLR camera and bandpass filters to improve input image quality in a 3D-reconstruction study of a wooden sculpture of a coyote and turtle from the Smithsonian American Art Museum. The sculpture has a large crack of concern to conservators, but its curved, dark shiny surface challenges image-based dimensional monitoring. Selecting infrared wavelengths rather than the visible light for 3D reconstruction input images reduced specular surface reflections and improved image contrast resulting in improved recording of the 3D shape. 3D-reconstructions using infrared radiation produce better reconstructions than those using visible light. In this case reconstructed surface discrepancies between visible light are ∼0.6 mm whilst those using infrared are ∼0.3 mm. Results suggest that reflected infrared images are more forgiving and flexible for recording 3D data over time for dark, shiny wooden surfaces and thus improve the reliability and comparability of image-based 3D-reconstruction.","PeriodicalId":17165,"journal":{"name":"Journal of the American Institute for Conservation","volume":"62 1","pages":"111 - 128"},"PeriodicalIF":0.5,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49498084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 3-dimensional ornate nature of this object posed additional challenges with respect to the development of a cleaning strategy, as the handling of gels on topographically complex gilded surfaces can be particularly problematic. Within a limited timeframe and without the use of sophisticated equipment, a comparative evaluation of a range of cleaning systems was designed to assess the efficacy of the removal of heavy soiling and bronze overpaint from this complex oil-gilt frame. This evaluation methodology entailed three different stages to better compare and select a suitable cleaning system. Free solvents, gels, and various emulsifiers were evaluated through empirical observation and documented using star diagrams (Excel radar charts), ultraviolet light, microscopy, and cross-section examination. The results indicated that hydrolyzed poly(vinyl acetate)-borate gels and modified silicone-based emulsions successfully removed the soiling and bronze overpaint while posing minimal risk to the oil gilded surface.","PeriodicalId":17165,"journal":{"name":"Journal of the American Institute for Conservation","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44788985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exacting in style and miniature in scale, each depicts one of a limited number of architectural motifs in black media. While compositions are repeated within the small set of known dessins-fumées, variations in superficial details and shading are observed between “copies.” The J. Paul Getty Museum has two of these rare objects, Moorish Arch and Courtyard of a Gothic Castle. The black materials used by Daguerre were characterized with non-invasive analytical methods, including digital microscopy, macro x-ray fluorescence scanning, Fourier-transform infrared spectroscopy, and Raman micro-spectroscopy; mockups were created to assess their potential methods of application. This research revealed that the Getty dessins-fumées are drawings and not produced by photographic or printmaking techniques. This study also characterizes the materials used to create the drawings and confirm the order in which they were applied. They are discussed with respect to how they address the uncertainty surrounding the development of photographic processes by Daguerre and others in the 1820s and 1830s.","PeriodicalId":17165,"journal":{"name":"Journal of the American Institute for Conservation","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49015359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Psychological health play a vital role in adherence to treatment regimen and self-management of diabetes. This study aims to identify the psychological predictors of self-care behaviors among patients with T2DM.Methods: A descriptive cross-sectional survey was conducted at a diabetic clinic at a tertiary care hospital in North India. Structured pre-tested personal and clinical profile and self-efficacy, diabetes distress, depression and anxiety, and complications and fear of developing hypoglycaemia due to diabetes mellitus in the future are measured through standardized questionnaires.Results: The mean age of the participants was 53.5 (±3.68) years, and 41.4% were in the overweight (BMI: 25.0-29.9) and obese (16.7%, BMI > 30) category. Self-care behaviours found significant association with self-efficacy (r = 0.34, P < 0.001), anxiety (r = -0.28, P < 0.001), depression (r = -0.28, P < 0.001) and diabetes-related distress (r = -0.30, P < 0.001). Further, self-efficacy (P = 0.001), diabetes distress (P < 0.001) and fear of developing hypoglycaemia (P < 0.001) were reported independent predictors of self-care behaviour in patients with T2DM.Conclusions: The current study suggests that self-efficacy, fear of hypoglycaemia and emotional state played an important role in adherence to self-care behaviour in T2DM management. Patients with diabetes mellitus should be routinely screened for psychological factors at diabetes clinics. Thus, developing tailored interventions to raise belief and self-efficacy might be a useful way to increase the involvement of patients in treatment.","PeriodicalId":17165,"journal":{"name":"Journal of the American Institute for Conservation","volume":"14 1","pages":"558-564"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11245295/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87857139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
