In paper conservation ethanol is used as an antifungal agent. However, information on the antifungal efficacy of this alcohol is scarce and often inconsistent. In this study, we clarify if ethanol is effective and safe to use in paper conservation in the short as well as in the long term. None of the tested ethanol concentrations (5–100%) promoted conidia germination, but rather delayed or entirely inhibited it, depending on alcohol concentration and contact time. In a simulation of an interventive treatment of samples colonized by fungi, all the tested ethanolic solutions (30, 70, and 100%) revealed antifungal activity. The best results were obtained with 70% ethanol, showing fungicidal properties on four of the five-tested fungal species (Aspergillus niger, Cladosporium cladosporioides, Penicillium chrysogenum, and Penicillium corylophilum). No deleterious effects of 70% ethanol on the tested paper were observed either in the short or in the long term. 相似文献

AbstractMost artworks require a stable microclimate and a field study has been undertaken to understand the environmental risks in a mountain church that is heated once a week. The church was selected on the basis of the artworks present and the existing heating system: a hot-air system which is popular due to its low cost and rapid response. The heating system is switched on only during the liturgical services and generates rapid temperature and humidity changes which, in the long run, are very damaging. The temperature stratification leaves people with their feet in cold air, whereas the air in the upper levels is too hot and dry. Moisture condenses on the cold walls. Deliquescent salts in masonry and frescoes undergo dangerous crystallization cycles. Wooden artifacts contract and expand in line with humidity cycles. Deposition of candle and incense smoke is increased, darkening the artworks. The paper discusses these problems, some common errors, and possible methods to mitigate the risk factors. 相似文献

In recent years Qatar has invested a significant sum of money on exhibitions of contemporary artists and public art. This paper discusses decision-making processes in the conservation of contemporary artworks installed in newly emerging art markets such as Qatar, where there are no established practices. In 2014, Richard Serra's East–West/West–East, an installation of four vertical plates made of weathering (Corten?) steel, which span one kilometre at heights so as to reach the level of the surrounding gypsum plateaus, was installed in the Brouq Nature Reserve near Zekreet desert, two kilometres from the sea in the western part of Qatar. The artwork is already considered by some a landmark for the isolated area. The plates have started to develop protective corrosion layers, although Corten? is not completely corrosion resistant when located near coastal sites. They have also started to bend and are heavily inscribed by visitors. Conservation of public art is complex, as site-specific artworks are linked with the landscape and defined by the relationships they develop with the public. Art installations of this magnitude demand not only conservation measures but also a management plan. The isolated location, the scale of the artwork, the aggressive environment, and the lack of supervision and monitoring of the area challenge current practices but offer an opportunity to develop methods to preserve art of site-specific art in new environments and diverse audiences. Monitoring will allow a better understanding of the interactions of visitors with the artwork and will shed light on the material's behaviour in this specific environment. 相似文献

This paper examines the preservation and curatorial approaches explored for the exhibition Silent Explosion: Ivor Davies and Destruction in Art at Amgueddfa Cymru – National Museum Wales (November 2015–March 2016). The collaboration between the artist, curator/researcher, and conservators is considered and the evolving and flexible way in which transient pieces were presented/re-presented is described. The paper offers a case study in the context of this exhibition and argues that regardless of whether it is in traditional media (such as painting) or as time-based media (unstable and open to interpretation), Davies' work challenges a perception of artworks as finished, single-authored objects. 相似文献

Explore a Painting in Depth, an experiment presented in the Canadian Collection of the Art Gallery of Ontario, consisted of a booth that offered seating for two visitors and, opposite them, The Beaver Dam, a 1919 landscape painting by the Canadian artist J. E. H. MacDonald. In a 12‐minute audio‐guided Exercise for Exploring, visitors were invited to engage in a creative process with the imagery of the painting. This paper sketches how the experiment evolved, presents the background of the Exercise for Exploring, and surveys the effects of the exhibit on a wide range of visitors. The question is raised: How can facilitating visitors' creative responses to artworks be part of the museum's educational mandate and its arsenal of interpretive resources? More broadly: Do strategies that foster and privilege visitor creativity, as well as honor the creativity of artists, affect the accessibility and relevance of the museum for the general public? 相似文献

Despite substantial literature on the dyeing of textiles, there is a lack of research about colouring Japanese mending papers (tissue papers) used for paper conservation purposes. This study investigates the fungal bioreceptivity of Japanese tissue papers after they have been treated with various dyes and pigments. A variety of toning materials including plant dyes, watercolours, acrylic paints, inks, pastels, gouaches, and colour pencils are commonly used by conservators for paper toning purposes. In this study, two Japanese tissue papers (Yukyu-shi and Sekishu Mare) were treated with selected plant dyes, watercolours, and acrylic paints and then inoculated with fungal species. Quantitative real-time polymerase chain reaction (qPCR) was used to quantify the DNA from Aspergillus niger and Penicillium rubrum as a proxy for fungal species abundance before and after inoculation and artificial moist heat ageing. qPCR primers which were universal for fungi amplified DNA from papers inoculated with A. niger and P. rubrum and these species were found to grow less on treated Sekishu Mare and Yukyu-shi papers compared with untreated papers. Sekishu Mare papers treated with artists' acrylic paints were found to be more resistant to fungal growth than similarly treated Yukyu-shi papers. This study suggests that for the best long-term preservation outcomes for paper materials in archives, libraries, galleries, and museums, acrylic paints generally perform better in conservation terms than most plant dyes and watercolours, although most colourants displayed some bioinhibition. 相似文献

ABSTRACTDuring construction of a 6 km long railway tunnel close to historic churches in Stockholm, a preventive monitoring model was applied for ensembles of large-scale immovable ecclesiastical artworks. Construction work such as blasting and pile-driving took place during five years under or very close to these immovable works of art. In Sweden, risk assessment related to construction work is focused on risks associated with the building; meanwhile, there is no common approach for protecting the immovable historic works of art and architectural surfaces. This paper discusses how a preventive model for vibration monitoring on immovable artworks was developed and used as well as how the preventive purpose was perceived by different stakeholders during and after the tunnelling work. Experience from this project concludes that monitoring that includes uniform visual inspection becomes crucial for being able to protect the artworks. The concept of vibrations standards relying on fixed numbers of critical vibrations levels for mitigating the effects of vibration on immovable art can be questioned based on experiences from this project. 相似文献

In fine arts, contemporary artists seek to showcase their artistic skills and concepts. There is very little awareness by most artists on the quality of materials they use in art production and the conservation needs of contemporary artworks which pose conservation challenges as materials used and the physical quality of artworks produced are secondary to what the artists seek to express. Of prime interest to them is the expression of concepts through various genres of art creation. However, the quality of material used by most artists is largely affected by their financial situation and inadequate knowledge on the durability of such materials. Artworks created using recycled materials such as found objects and cheap materials like poor quality paint on paintings, low grade paper in artworks, or poor quality wood present conservation challenges to professionals in galleries. The end product are artworks made from composite materials, some stable and unstable. Thus professionals are faced with a dilemma to reconcile the conservation needs of these artworks and the artists’ expression of their concepts. Moreover, in the absence of remedial conservation measures, artworks are prone to deterioration. This is worsened by dwindling donor and government funding which negatively impacts on the gallery's capacity to conserve the art. Additionally, conceptual expression, artistic creativity, and commercialisation of the art are of priority over conservation. Therefore there is need to maintain a balance between the need to express concepts and commercialise the art on one hand and to conserve the contemporary artworks on the other hand. 相似文献

AbstractHistorical texts have much to offer young researchers in Hong Kong and Mainland China. Yet, many students feel that such resources are of no value to them. Consequently, academic library usage rates for historical East Asian texts are low, and continue to drop. In Hong Kong and Mainland China, however, there still remains a widespread appreciation of Chinese calligraphy. Through leveraging this interest, academic libraries in East Asia can motivate university students to engage with historical texts and discover what they have to offer. This paper will recount and reflect upon the Calligraphy Connections Project, an initiative aimed at getting students to engage with historical East Asian texts through the creation of calligraphy artworks, which were subsequently exhibited to the public. 相似文献

If science can inspire art, can art inspire interest and learning about science? There is widespread experimentation in using the arts as tools for communicating science in science museums and other settings. When the arts work well in communicating important aspects of science, they can be powerful tools. Three artworks are discussed: Particle Fever, a film in development about particle physicists and the hunt for the mysterious Higgs Boson; The Great Immensity, a National Science Foundation‐supported musical about climate change: and Guardians, a ballet co‐produced by and performed in an aquarium. These three art‐and‐science hybrids have given this writer some understanding of at least one way to sift the successful from the unsuccessful ventures. 相似文献

Participatory art is a contemporary movement requiring viewers to take an active part in the artwork, by means ranging from interaction with materials to creative contribution. Artistic developments in the twentieth and twenty-first centuries, such as political and social engagement, led to the rise of participatory practices. Concurrently, museums have reacted to falling attendance and cultural shifts by seeking to create more engaging experiences for visitors. At the Denver Art Museum, this has led to an increased interest in displaying and collecting participatory art. Through case studies of works in the collection of the Denver Art Museum, Walking in Venus Blue Cave (2001) by Ernesto Neto and ¿Being Home? (2009) by Rupprecht Matthies, this paper explores the conservation of participatory artworks in museum collections, including their maintenance on display, long-term preservation of their interactive nature, and the possibility of involving communities in conservation actions and decision-making. 相似文献

Spectrometric handheld light meters that can provide adequate data for evaluation of replacement bulbs for contemporary art objects are now commercially available. This approach was taken to assess potential replacements for the incandescent street lamps in Chris Burden's Urban Light at LACMA, Los Angeles, USA. These meters are also useful tools for monitoring and characterizing museum lighting, which are currently done with illuminance (lux) meters. The new spectral light meters will enable conservators to tailor lighting recommendations for individual artworks, when spectral information from these meters is combined with damage function data on artists’ materials. The latter information can be obtained for some materials by a small modification to the microfade testing procedure, as exemplified by microfading colored samples Henri Matisse created during the design phase for La Gerbe. 相似文献

With the ratification of a new constitution in Afghanistan in 1964, freedom of expression was allowed and a number of independent newspapers emerged, among them the first satirical periodical, Tarjomān or Interpreter. This paper explores Tarjomān's contribution to satire in Afghanistan, a critical genre in a closed society. Tarjomān not only published satirical pieces in traditional forms, but also introduced new forms, especially political cartoons and satirical fiction. It transformed old forms for new sociopolitical needs, changing the status of satire from mere mockery to high art and making it a political tool. This was mainly due to the artistic and political skills of its founders, Nawin and Bashir. As well, satire found its closest connection with politics in modern times in Tarjomān. 相似文献

First aid for flood-damaged paper using saltwater: The inhibiting effect of saltwater on mold growth
《文物保护研究》2013,58(3):164-171
AbstractWith the aim of developing a new easy-to-use method for rescuing flood-damaged paper, the effect of saltwater on the inhibition of fungal growth on paper was investigated. This procedure could be used instead of, or assisted by freeze drying. Cellulose-digesting Trichoderma reesei, three types of fungi representative of fungi growing on paper (T. reesei, Aspergillus terreus, and Aureobasidium pullulans) and various naturally airborne fungi were cultured on cellulosic materials in liquid media containing artificial seawater with different salt concentrations. The addition of salts successfully inhibited the growth of T. reesei on microcrystalline cellulose at the concentration of 3.2% (m/m) or higher. The critical salt concentration, 3.2%, is within the general range of salt content in seawater. Other solutions of salts similar to sodium chloride also inhibited fungal growth. Although the observed growth-inhibiting effect was attributed to the high osmotic pressure of the salt solution, physiological effects depending on ion species used were also considered to be possible. The growth of all three types of fungi on copy paper was inhibited effectively when the salt concentration was increased. The growth of various fungi on pure cellulose, with enough oxygen supplied to pores, was completely inhibited (as assessed by visual examination) for 24 days at salt concentrations of 3.5% (m/m) or greater. The fact that the effect of saltwater on cellulosic materials was observed even under optimum medium conditions implies that fungi would be considerably inhibited on flood-damaged paper immersed in saltwater. This method is a promising first aid measure when circumstances do not allow for flood-damaged paper to be dried immediately. 相似文献

This paper outlines a history of the union organizing of the American Newspaper Guild at Thomson Newspapers’ Peterborough Examiner in Canada from 1968 to 1969. It examines the communication tools that union members used to facilitate this labor organizing and “bite back” at the profitable Thomson chain. Peterborough newsworkers went on strike from November 1968 to April 1969 over union recognition. During the strike, the union members built an unprecedented alliance with Ontario university students, collaboratively launching a strike newspaper called the Peterborough Free Press. Expanding on the concept of temporary labor convergence, this paper considers how strike newspapers can be seen as a form of alternative journalism that newsworkers use as a campaigning tool to communicate their struggles to the public and put pressure on news corporations to bargain with them. This case study is situated in the local institutional contexts of labor relations at the Peterborough Examiner and the news industry in Peterborough, where Thomson Newspapers had a media monopoly. It is based on labor standpoint and signal juncture analyses of union archival documents and newspaper content. The research ultimately suggests that newsworkers should not only focus on communication tools but also build bridges with community members. 相似文献

This paper examines the ways in which two Internet-based civil society groups, Hasiru Usiru and Praja, negotiate online and offline spaces of collective action in Bangalore, India’s “IT City.” Based on ethnographic research, the study extends collective action theory through an examination of communicative interactions and experiences of urban civil society actors in a developing country. The paper highlight factors that impede and support collective actions, including attitudes toward the Internet as a tool for democratic engagement, ideological motivations, and perceptions of identity and membership, among others. Such a line of inquiry is significant in highlighting the possibilities of ICTs for collective action, while simultaneously avoiding the tendency to inflate and overestimate their capacity to produce social change. 相似文献

Using the example of communication about risk in a primary care setting, this paper puts forward a method of developing and evaluating a detailed search strategy for locating the literature for a systematic review of a ‘diffuse’ subject. The aim of this paper is to show how to develop a search strategy that maximizes both recall and precision while keeping search outputs manageable. Six different databases were used, namely Medline, Embase, PsychLIT, CancerLIT, Cinahl and Social Science Citation Index (SSCI). The searches were augmented by hand-searching, contacting authors, citation searching and reference lists from included papers. Other databases were searched but yielded no extra references for this subject matter. Of the 99 papers included, 80 were indexed on Medline. The Medline search strategy identified 54 of them and the remaining 26 were located on other databases. The 19 further unique references were found using the other databases and methods of retrieval. A combination of several databases must be used to maximize recall and to increase the precision of searches on individual databases, thus improving the overall efficiency of the search. 相似文献

This paper uses a range of case studies from contemporary art and indigenous collections to explore synergies between the disciplines and pose questions about contemporary perceptions of condition and durability. The idea that value is only connected to original material or specific perceptions of condition has been challenged repeatedly by the very makers and primary users of these collections. Nevertheless, old expectations in relation to collections may still affect conservation processes. The conservator is positioned at the center of these tensions, trying to understand, negotiate and mediate the interests and values of dynamic layers of significance associated with the object being treated. Attempting to homogenize or generalize these relationships would directly affect the complexity of the meanings of the artworks and run the risk of hollowing them. 相似文献
