Abstract

Monitoring for insect pests in museums is conventionally carried out by using sticky ‘blunder’ traps. Trials of traps enhanced by the addition of the calling pheromone of Anthrenus sarnicus (Coleoptera; Dermestidae) are shown to increase capture rates for this species, thus rapidly identifying areas requiring appropriate counter-measures. Progress on developing comparable techniques targeted at another museum pest beetle, Attagenus smirnovi, is also reported.  相似文献

ABSTRACT

The National Museum of Ethnology, Osaka, Japan, collects a vast amount of materials and information related to peoples’ life and culture, and makes them available to society through exhibitions and other activities. The number of collected items is increasing every year: 343581 objects have been collected from Japan and abroad as of March 2017. The continuous efforts have been necessary to improve storage conditions and to save space for both general and special storerooms. The former, which account for 90% of the storage capacity of the museum, are air-conditioned during working hours, with temperature and relative humidity (RH) settings varying with the seasons. The latter, which house objects for which strict conservation conditions are required, are air-conditioned for 24 hours with fixed settings of temperature/RH throughout the year determined by the nature of the materials from which the objects have been made or formed. Storage re-organization began with special storerooms, for which the number of objects and the storage area are far more limited in comparison with the general storerooms. The storage shelves for fur/skin/feather (almost 1000 objects) and for carpets (almost 550 objects) were all renewed in FY2007/2008. Then two large-scale innovation projects for general storerooms were conducted: construction of storage areas for ships equipped with a CO2-based and anoxic pest treatment facility (FY2015), and a complete refurbishing of the general storeroom for large objects (FY2016). Windows were set in the corner of this storeroom to provide visitors an opportunity to view and learn about the museum activities. In parallel to the above projects, daily storage improvement efforts have been undertaken. Storeroom No. 3, chosen as an example for general storerooms for small and medium-sized objects, was used to investigate the range of issues related to the shelving arrangement and storage conditions. Guidelines for storage re-organization were formulated according to the results of the investigation and according to the experiences gained through the renewal of special storerooms. Storage re-organization undertaken in storeroom No. 3 was conducted for 6 years at the rate of around 2000–4000 objects per year with a low budget and with reuse of existing shelves. In FY2016, all objects in storeroom No. 3 were properly redistributed. About 40% of the storage space was saved. Over these 10 years of storage re-organization, preventive measures have been taken for sustainable collection management. As early as FY1992, pest trap investigations have been carried out seasonally. Since FY2004, the results of investigations have been analyzed using a customized computer program. Subsequently, appropriate integrated pest management measures have been taken. In addition, since FY2014, energy-efficient air-condition control has been adopted for general storerooms. It consists of switching off air-conditioning in spring and autumn, and of starting it only when the temperature or RH values become too high in summer or too low in winter. Because the turning-off of air-conditioning causes comparable or even less climatic fluctuation, it was considered acceptable both economically and from a conservation perspective. It is estimated that turning the air-conditioning off during transitional seasons brings cost savings of about 3000000–4000000 JPY (about 26800–35700 USD as of 23 September 2017) per annum, which accounts for almost 30% of the electricity expenditures for all general storerooms.  相似文献

ABSTRACT

The Natural History Museum (NHM), London was one of the first national museums to introduce a museum-wide integrated pest management (IPM) strategy that includes the concept of risk zones (Doyle, Pinniger, and Ryder 2007). This system is based on the principle of pest prevention within a museum building, which will always have a resident population of pest insects. The loss of Dichlorvos [DDVP] resulted in an urgent need to implement a museum-wide IPM programme to protect vulnerable collections both in storage areas and on display. With such a large, diverse collection in a complex series of interconnecting buildings, it became necessary to break the programme down into sections. Thus the development and implementation of the concept of risk zones: classifying areas of the museum from high risk to low risk has proved a useful and effective method to promote staff awareness and best practice as part of a comprehensive IPM programme.  相似文献

The webbing clothes moth Tineola bisselliella (Hummel, 1823) is one of the most common museum pests and can be found all over the world. The larvae damages objects made of feather, wool, fur, and other keratinaceous materials. Pheromone traps are important tools in integrated pest management, which allow the detection of infestations and evaluation of their extent. Organic-rich dust (detritus) or other materials of animal origin, such as dead birds, can be an alternative food source for the moths. This paper analyzes monitoring data collected with pheromone traps from six different museums in Vienna and Berlin and tries to differentiate between moths resulting from infested objects or moths coming from other food sources, such as organic-rich dust. Annual totals of moths trapped and catch rate (moths per trap) are important guides for selecting appropriate remedial measures. Long-term data (over six years) enabled us to interpret monitoring results and differentiate between active infestation of objects and cleaning or housekeeping problems. However, detailed knowledge of the site and buildings, availability of high-quality food for the larvae, and lack of regular cleaning are also important factors to consider when interpreting the data.  相似文献

This paper discusses the three phases of the lifecycle of the bojale drum: its custodianship by the queen of Bakgatla‐baga‐Kgafela; the drum's use in bojale (girls’ initiation ceremony); and its presence in Phuthadikobo Museum, a community institution. This lifecycle was observed by the author prior, during, and post initiation in bojale, a girls’ initiation school in 2009. The drum's use, its royal significance and sacredness, is barely documented in its museum record, which can result in its misinterpretation. The recommendations are that the drum's documentation, preservation, handling, and storage in the museum should incorporate its intangible cultural attributes if the museum is to be relevant to the Bakgatla‐baga‐Kgafela community. In conclusion, bojale drum is an example of how material culture can connect a museum with its community through the living culture of bojale.  相似文献

ABSTRACT

The 2008 Wenchuan earthquake brought numerous issues to the attention of researchers of seismic mitigation in Chinese museums. After the Wenchuan earthquake, the structural design team of Chengdu Museum conducted a series of research projects on seismic mitigation and subway vibration control design of buildings. These projects included the following topics: optimization of design, numerical simulation of seismic performance, analysis of key technologies for the base isolation structure, in-depth studies on structural vibrations caused by the nearby subway, and proposals for reducing structural vibrations. In 2015, after the superstructure of Chengdu Museum was completed, conservators evaluated the safety of permanent exhibitions under earthquake conditions. Seismic protection devices were installed on the showcases according to the preventive conservation requirements for museum collections. Reinforced measures were used for museum collections according to the methods suggested in the document ‘Specification for seismic protection of museum collection’ (WW/T 0069-2015). The conservators also built a systematic platform for earthquake monitoring for museum collections. Preventive conservation studies on seismic protection and subway vibration control in Chengdu Museum are summarized and forecasted.  相似文献

Abstract

Accelerated corrosion tests have been used for almost 30 years to exclude corrosive materials from museum display and storage. The method reported by Green and Thickett in 1995 has been developed to allow the evaluation of three metals (silver, copper and lead) simultaneously in a single test. Comparison of a wide range of materials has shown that the differences in results introduced by this modification are less than the differences encountered with replicate tests using the same material employing the previous method. Problems encountered with corrosion in lead control tests have been investigated and the method has been modified to remove this effect. The cleaning method for the test vessels has been modified to exclude the hazardous chemical, chromic acid.  相似文献

ABSTRACT

Previously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO2 was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO2 decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present.  相似文献

Speculation about the character and purposes of American art museums has occasioned intense debate since their inception—never more so than today. Whether to be elitist or populist, object‐based or audience‐based forms the crux of many heated arguments. This article asserts that, in the midst of competing philosophies, the successful American art museum has in reality grown from an amalgam of ideas that form a via media or middle path, far more inclusive and pragmatic than is usually noted. This comprehensive philosophy is most effectively demonstrated in the work of Henry Watson Kent at the Metropolitan Museum of Art in New York during the first decades of the twentieth century. The work of Kent and his colleagues at the Metropolitan Museum is here examined as a paradigm for the via media museum practice that speaks to the aspirations of America's current art museum leadership.  相似文献

Digital technologies and their uses within museum collections have until recently been explored primarily from a technical viewpoint. Increasingly, museum professionals are moving beyond technologically‐driven reasoning to entertain new ways of conceptualizing both collections and information. This is leading to knowledge models beyond those already imagined. This paper considers the synergy between theoretical ideas in the academy and the computer ontologies that have been brought to bear on collections information. Drawing on user research findings from the Themescaping Virtual Collections project and the work of leading literary and media theorists, the paper examines how user needs and digital technologies are reformulating our understanding of museum collections and the relationships between museums and audiences.  相似文献

Abstract

Chloride-contaminated archaeological iron is unstable and problematic to store and display within museum collections. Reducing its chloride ion content using aqueous desalination followed by storage in controlled relative humidity offers one treatment option. This study reports a quantitative assessment of chloride extraction by aqueous deoxygenated alkaline desalination solutions from 120 individual archaeological iron nails. The three treatment methods comprised alkaline sulphite solution (0.1 M NaOH/0.05 M Na2SO3) at room temperature and at 60°C and sodium hydroxide solution (0.1 M) deoxygenated using a nitrogen gas positive pressure system at room temperature. Chloride extraction was monitored using a specific ion meter. The nails were digested after treatment to measure their residual chloride content. A wide range of extraction patterns emerged, with the majority of individual treatments extracting 60–99% of the chloride present. Residual chloride levels for 87% of the objects fell below 1000 ppm and 42% were below 200 ppm. Although no treatment extracted 100% of the chloride in the object, alkaline desalination produced very significant reductions in chloride content. The impact of this on future corrosion of the objects is discussed. This quantitative and statistically viable assessment of deoxygenated desalination treatments provides evidence to support their use in conservation practice, which will impact on procedures for the preservation and management of archaeological heritage.  相似文献

ABSTRACT

A decontamination treatment using liquid CO2 (li-CO2) and specifically developed for the requirements of museum objects (Lombardo, T., M. Wörle, V. Hubert, E. Hildbrand, I. Mayer, C. Hinterleitner, U. von Arx. 2020. “Influence of Process Parameters on Chlorinated Biocide Decontamination by li-CO2 on Artificially Contaminated Model Materials.” Studies in Conservation, in press, doi:10.1080/00393630.2019.1641001) was first tested on model materials of wood (with and without coating), silk, and wool with different dyes, paper, and leather in order to evaluate possible material changes. Then, selected museum objects from the collection of the Swiss National Museum were treated to determine the efficiency of biocide decontamination and any resulting chemical and/or structural changes. Results show that dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and chlorpyrifos were successfully removed. Wool, silk, leather, and non-coated wood did not experience any detectable modifications, while moderate to major modifications were observed in wood coated with shellac and polychromy.  相似文献

By far the most common species of woodworms perceived to be the main cause of damage to wood, and in particular to wooden art objects, are Anobium punctatum de Geer and Hylotrupes bajulas of Coleoptera family. In search of non-chemical methods for eradicating these wood pests, microwave (MW) heating can be an effective tool to help control the insects in their different life stages (eggs, larvae, and adult). The effect of 2.45?GHz frequency MW exposure on wooden art objects is described and discussed. MW heating time is reported in connection with lethal temperature of the pest and moisture content of the treated wooden object. The treatment was carried out using Microwood 12, especially conceived for portability, easy operation, and control. Microwood 12 consists of a switch mode high-voltage power supply and an industrial continuous wave magnetron connected to a rectangular-shaped horn antenna. The measure of temperature and control of operation is done via a built-in infrared thermometer.  相似文献

ABSTRACT

Clothesmoths catch data fromhistoric properties confirms numbers are on the increase in England. Citizen science research was conducted using Tineola bisselliella pheromone traps handed out from English Heritage properties from April to September 2017. One hundred and ninety-two participants recorded moth counts from residential properties in 42 counties in England. Using an average number of moths per trap, geographical spread indicates higher numbers in warmer southern counties of England. Pale-backed clothes moths Monopis crocicapitella were caught in significant numbers suggesting a new insect pest risk for historic house collections. Threshold numbers for clothes moths that could indicate an active infestation are proposed. Residential flats appear to be more vulnerable to clothes moth activity possibly related to the shared walls or spaces. The research was launched using a public relations campaign called ‘Operation Clothes Moth’ which generated major media activity across the internet, radio, television, newspapers and magazines. Public awareness of insect pest management, preventive conservation and the work of conservators and conservation scientists was significantly increased.  相似文献

Abstract

Technology-related organizations have several important leadership roles to play in creating an environment to nurture a successful transition of libraries into the new roles they will play. Among these roles are helping to create standards and protocols, advocacy, mentoring, creating heroes, and underwriting leadership training for new members of the profession. The willingness to take a leadership role presents several potential traps, which must be avoided diligently, through humility and vision.  相似文献

Abstract

Insect infestation is a serious problem in museum collections in Spain and Latin America. This paper investigates the efficacy of modified atmospheres as an anoxant for museum pests, using wooden objects including polychrome sculptures infested by Cerambycidae and Anobiidae species. Insects of long life cycle have been found to be very resistant to carbon dioxide atmospheres. However, inert gases such as argon and nitrogen used in plastic barrier bags effectively eliminated insects in all stages of development. No chemical alteration was observed in the treated materials, including polychromy. These treatments are in progress in a project for biodeterioration control in countries with both tropical or subtropical and Mediterranean climates.  相似文献

Abstract

A broad outline of the considerations which arise with regard to the conservation of a museum collection of tapestries is given in this paper. The various types of damage to, and deterioration of, tapestries is discussed.

Various methods of washing and dry cleaning, and the equipment necessary for these procedures, are reviewed, and a caution is included as to the necessity of testing all dyes for colour fastness in both water and any solvent used for dry cleaning. The equipment, materials and techniques of repair are discussed; three methods of repair being currently used in museums and specialist workshops — re-weaving, stitching on to a backing and the use of synthetic resins for impregnation and adhesion to a woven support. It is suggested in conclusion that the optimum method of repair in museums is stitching on to a backing. More research must be undertaken into the use of synthetic resins, and re-weaving usually alters the original appearance of the tapestry.

Finally, the need for specialised conservation staff in a museum with a tapestry collection is emphasised.  相似文献

ABSTRACT

Many museums are housed in historic buildings, sometimes the building itself is part of the museum collection. Creating a stable environment by providing a nearly constant temperature and relative humidity at correct levels decreases the risk of object degradation. Maintaining this steady indoor environment, however, increases energy consumption and risks to the historic building. Museum display cases offer a solution to the mitigation of risks to which valuable objects may be subjected by providing an extra layer of protection to indoor climate fluctuations. The Anne Frank House is a historic house museum located in Amsterdam. The museum has undergone several renovations in the last years to deal with an increase in the number of visitors to over 1.2 million a year. The original diaries and other documents of Anne Frank are permanently on display in the Anne Frank House. With the recent refurbishment the possibility arose to design a new state-of-the-art display case. This study presents the results of the experimental research related to the design, performed in-situ. The temperature and relative humidity in the new exhibition space and inside the new display cases were monitored to gain insight into the hygrothermal behavior of these controlled environments. A complementary numerical study was performed to investigate effects of dynamic climate control of the exhibition gallery and climate conditions in the display case under various circumstances. Four main conclusions are presented in this paper. The investigated display case design is able to provide a stable relative humidity environment by means of silica gel, while using an active box-in-box climate control system to create stable temperature conditions. The inner case temperature depends on the temperature supplied by the display case air handling unit. Protocols must be in place in case of malfunction or failure of the climate control system of the display case. The air handling unit of the case needs to be shut off to create a passive environment for the objects on display until necessary actions are taken. Exhibition gallery set points can be less stringent when susceptible museum objects are on display in the display case. The environments are separated and provide an opportunity for energy saving set point strategies. The last conclusion drawn is that the numerical study provides valuable insight into imposing dynamic control of set points for temperature and relative humidity in the exhibition gallery and the effect on the display case environment.  相似文献
