Abstract

Two projects undertaken as part of a Unesco project for the conservation of the cultural heritage of Ecuador are described. Wall paintings in the dome of the church of EI Sagrario in Quito had been damaged by watersoluble salts carried by penetrating rainwater. The dome was protected with a hydrophobic coating and allowed to dry out prior to treatment of the paintings. As part of a programme to train Ecuadorean specialists, paintings on the south wall of a cloister in the convent of San Diego were selected as a model of conservation work.  相似文献

ABSTRACT

Cultural heritage assets are continuously exposed to risks and hazards. With the main aim to assess deterioration and improve conservation methods, the scientific community has proposed a variety of tools for the early identification of changes in heritage. Multidisciplinary approaches are common in heritage monitoring and conservation. This paper investigates the potential of change detection algorithms developed in remote sensing, and here applied at the monumental scale instead of the geo-spatial one. A monitoring methodology which integrates photogrammetry, 2D/3D change detection, and data interpretation is described and tested on the façade of the church of Stavros tou Missiricou (church of the Cross within the walls) in Nicosia, Cyprus.  相似文献

Abstract

The Palacio del Almirante in Cuzco, Peru, was badly damaged by an earthquake in 1950. Restoration work was interrupted due to lack of funds and various decorative elements, including the coffered wooden ceilings which had been dismantled, were dispersed. When conservation work resumed in 1975, the pieces had to be located and reassembled, with the help of photographs taken before the earthquake. The separate pieces were cleaned, disinfected and consolidated, missing pieces were replaced and the polychromy was reintegrated. Since the original beams could no longer support the weight of the ceilings, a system was devised whereby the ceilings were suspended from above by iron bars.  相似文献

ABSTRACT

This present work focuses on the mapping of marbles, decorative patterns and area of the mosaics of the St. Nicola’s Basilica in Bari (Italy) by their photogrammetric survey. The extraordinary importance of these mosaics is due to the stylistic uniqueness and the undisputed workmanship and to the employed materials for tesserae. These mosaics include the white and polychrome marbles, used in the Roman age and reused in medieval artistic production, and imitation stones used as substitutes during the past restorations. The digital survey was realised by the photogrammetric reconstruction of mosaics collecting a photo dataset, after the mosaics redrawing by an image processing software and finally implemented it with lithological identification marbles. It allowed to obtain a punctual mapping of materials, through which to identify original areas and restoration areas, decorative patterns, recurring geometries. The research carried out, supported by the photogrammetric reconstruction as established method for high resolution digital reproduction and mapping, not only ensures the conservation and improvement of the enjoyment of the mosaic floors of the St. Nicola’s Basilica, but allows to conduct studies on materials, decorative patterns and restoration areas directly on the digitized product.  相似文献

Abstract

The paper discusses the methodology adopted for and the results derived from a pilot project to conserve the lead and lead alloy communion tokens in the collections of St Andrews University. For the project a new conservation process, ‘potentiostatic reduction’, was developed, involving reduction of the tokens at ?1·2V vs. SCE (saturated calomel electrode) in 0·5M H2SO4, The aim of the pilot project was to test the effectiveness of the new process in tackling a largescale conservation problem by observing its effects on a wide range of tokens made of various alloys and suffering from varying degrees of corrosion. The results of the pilot project indicated that potentiostatic reduction is as effective as standard electrolytic reduction. Since the new technique greatly reduces the time required for the conservation of individual artifacts, there are substantial savings in conservation costs.  相似文献

Abstract

Three Hispano-Moresque woven textiles dating from the first half of the twelfth century were restored for an exhibition. The first two are from the reliquary of St Librada in Sigüenza cathedral and the third is from the tomb of St Bernard Calvó in Vich. The first piece depicts addorsed griffins, the second, eagles with extended wings and the third, facing sphinxes. Contained within circles, they belong to a class of textile known in mediaeval documents as pallia-rotata. The spaces between the circles are decorated with typically Islamic designs, and with representations of plants and animals. A similar material was used for all three pieces: silk for both warp and weft, with gold thread for certain decorative motifs. All three textiles were found in a fragmentary condition; they had been glued and sewn onto thin card. The fibres were in a fairly weak state and had lost much oftheir flexibility and resistance. Apart from the work of restoration, the dyestuffs and the metal thread were analyzed and the decorative motifs were reconstructed using scale drawings.  相似文献

ABSTRACT

A sharp decline in the number of reference queries prompted the library administration at Indiana State University to begin a project to combine the circulation, reference, and IT desks to reduce staffing at a new consolidated service point. All faculty and staff in the reference/instruction and circulation units participated in the project. The new arrangement and subsequent removal of librarians from routine desk duties have expanded instructional opportunities, consistent with the university's goals. Project participants plan further assessments to better determine the impacts of the new service arrangements.  相似文献

ABSTRACT

In this article, the authors present a case study on a teaching and learning initiative in digital humanities at Connecticut College. The article outlines a project in which students in a midlevel history course collaborated with library staff and faculty to develop a digital exhibition on a nineteenth-century journal in the College's collection. The cooperative approach and institutional support that the team received provided an effective and flexible means for achieving common goals. As students applied emergent technologies to college collections, they were able to conduct meaningful research and bring archival resources to new audiences.  相似文献

Abstract

A survey is given of the environment of the monument, including its geographical and geological setting and meteorological data collected near the monument. The construction of Borobudur and the origin and consequences of damaging factors such as uneven settlements are discussed. Preliminary research required e.g. drilling programmes, soil mechanical studies, stone deterioration studies and investigations into the manufacture of concrete for foundations from local sources. The technical solutions proposed for the safeguarding programme are described in detail. Cost estimates, the organisation of the restoration project and landscaping and site development are mentioned. The duration of the project is estimated at six years. The complex and multi-disciplinary nature of the project requiring systematic planning both in the research and preparatory phases and in the implementation is stressed. Disciplines involved include amongst others: airphoto analysis, archaeology, architecture, chemistry, conservation techniques, geology, geophysics, hydrology, impermeabilization technology, landscape planning, microbiology, petrography, physics, soil mechanics, surveying and terrestrial photogrammetry.  相似文献

ABSTRACT

JSTOR has been committed to two goals over the past decade: preserving scholarly journals in electronic form and providing access to them as widely as possible. Since 2001, for example, JSTOR has administered a program in Russia and Belarus in which 27 institutions have received access to JSTOR with the support of The John D. and Catherine T. MacArthur Foundation. This article describes the lessons learned so far during this project and provides an overview of how the archive hopes to move forward in the years to come in this region.  相似文献

ABSTRACT

A Center for Research Libraries working group on cooperative collection development in the sciences and technology identified the geosciences as a domain whose current and historical publications make ideal candidates for a digitization demonstration project, due to their utility and the diverse nature of their text, tables and images. State geological surveys engage in some of the most important and practical fieldwork undertaken by geologists. State geological surveys and maps have had a critical impact in the discovery, exploration, use and conservation of natural resources. As a consequence, close to 2,000 selected publications from the states of Illinois, Pennsylvania, Texas and Wyoming were chosen for the scope, quality and variety exhibited in them. The eighteen-month digitization pilot project will, upon conclusion, design a self-sustaining model for a continuation program.  相似文献

SUMMARY

Setting prices in fee-based information services presents many challenges. Each service and its parent institution have a different definition of “cost recovery” and a different set of local accounting rules and procedures. The manager assesses the organizational goals and strategies, and then reviews the standard pricing models to determine which one best matches local objectives. This paper explores cost accounting methodology to illustrate one method of costing services and determining prices to cover those costs.  相似文献

SUMMARY

This article will discuss three years of collaboration between the Freshman Engineering Program and the Engineering Library of the University Library System at the University of Pittsburgh. This collaboration has resulted in a library research project that is integrated into the freshman curriculum. The project ultimately provides the students with a research structure for presentations in an annual mock professional conference. The mission of the Freshman Engineering Program's academic and advising components is to create a first-year experience that promotes the student's continued pursuit of an engineering degree through commitment to clearly understood and self-declared goals. The goal for the Engineering Library is to introduce library research as a necessary skill-set for successful engineers. The successful outcome of all of these goals requires the collaboration between “teaching” faculty and “library” faculty and results in better prepared, more focused students. Developing and integrating a library research project into the freshman engineering academic curriculum is a significant opportunity for library instruction, and the approach demonstrated here may be transferable to other disciplines.  相似文献

Abstract

Crystallization of sulphates in the form of gypsum and mirabilite/thenardite is one of the main causes of the accelerated disintegration of historic frescoes. The sulphur, which is necessary for these processes, may originate from a large number of different sources. Although the nature and velocity of the processes causing the damage, as well as the possible transport pathways of the saltforming ions, can be determined with reasonable accuracy, reliable information on the origin of the ions is seldom forthcoming. Sulphur isotope ratios were determined for various construction materials and salts from the church at Eilsum (Lower Saxony, Germany) where the romanesque frescoes have suffered serious damage. The studies showed clearly that sulphate on the walls inside the church, in contrast to that on the outside walls, originates mainly from the ground beneath the church from where capillary rise takes place within the walls. This information on sources and pathways of saltforming ions may contribute towards developing a programme of remedial measures.  相似文献

ABSTRACT

The Program for Cooperative Cataloging (PCC) has aroused controversy by promoting the value of cataloger judgement in its BIBCO program. Because this issue at times eclipses broader discussions about the PCC, it is useful to revisit some long-term values and issues in cooperative cataloging to gain a better understanding of the Program. The PCC is attempting to find realistic approaches to the issues of cost effectiveness and local flexibility while continuing to address the professional values that have historically motivated cooperative cataloging. Participating in the PCC can allow catalogers to reconcile their professional goals with the financial realities of their local institutions.  相似文献

ABSTRACT

This article explores the challenges faced and overcome by The College of New Jersey Library while digitizing a large amount of delicate material without any staff specially dedicated to the project and without any funds allocated specifically to support it. To achieve the project's goals without incurring additional cost, project management surveyed the utilization rates of existing library resources. This led to the discovery that underutilized resources and previously purchased equipment in the library could be assigned to the project, without negatively impacting other areas of the library. Allocating these resources to the project resulted in increased digitization progress without incurring additional staffing or equipment costs. Support from and collaboration with other departments on campus also assisted in staffing and promoting the project.  相似文献

Abstract

The restoration of the Cavaillé-Coll Romantic organ housed in La Merced Church of Burgos, Spain is described in this paper. The organ was affected by a fire that took place in the church. The effect of the fire on the pipes differed depending on their location within the instrument. A combination of analytical techniques (X-ray diffraction, scanning electron microscopy with energy-dispersive X-ray analysis, particle-induced X-ray emission, metallography, and specific density) allowed the accurate determination of the microstructures and compositions of the alloys used to make the different pipes of the organ, some of which had a high tin content and others which had a high lead content. The most damaged pipes were replaced by reconstructed pipes made out of metallic sheets of the same composition as the originals, to ensure a historically accurate sound.  相似文献

Abstract

The National Curriculum for England and Wales, implemented following the 1988 Education Reform Act, has had a profound impact on learning resource needs in schools. Whereas in many other countries the centralization of decision making over the content and delivery, of the curriculum is well established, the education system in the U.K. has, until recently, been characterized by fragmentation and a lack of central political direction. Teachers and librarians in the U.K. had previously worked within a culture which allowed considerable autonomy, with school library services provided by the local education authority as an additional resource for schools. School librarians are now being faced with the need to provide for a centrally directed curriculum, and to support specific information skills teaching in schools, increasingly without the support of a school library service, the service provided by public libraries as agents of the local education authority, to supplement libraries within schools. The use of information technology, has also become more significant.

A British Library funded project, undertaken at Loughborough University's Department of Information and Library, Studies, has investigated the ways in which English secondary, school libraries are meeting these new challenges as the U.K. education system undergoes profound cultural and organizational change. The management of change within school libraries was a major task, and it was here that strategies for planning mirrored those being undertaken in the schools as a whole. Applying the principles of school development planning to the library emerged as a major feature of effective school libraries.  相似文献

Abstract

Two iron swords from Luristan were examined by X-rays and using metallographic sections. The first sword was shown to have a hilt made of five pieces of metal joined by four rivets, while the pommel was secured by a dowel on the end of the tang. Hilt and blade were sectioned for metallographic study. This showed that while the core of each part was pearlite, decarburization had taken place at the surfaces to give ferritic structures. The second sword was shown to have been made of seven pieces. The pommel was secured as in the first sword, but all other pieces were joined by fitting into prepared slots, the edges of which were burred. A section was cut from the hilt at a point where a decorative band had been applied. This showed large-grained ferrite at the surface and fine-grained ferrite with cementite at the boundaries in the core. It is argued that work previously carried out by other metallographers was inconsistent due to inadequate sampling, and that swords of this type were essentially of wrought iron, the presence of pearlite being accidental rather than intentional.  相似文献
