Abstract

Descente des vaches (1836) by Théodore Rousseau in the Mesdag Collection in The Hague is barely readable and its paint layers are in poor condition. The surface of the painting is strongly deformed and cracked, the whole painting has darkened and especially the greens have lost all or most of their colour resulting in brown passages. Large passages of the painting that were painted with multiple thick and medium-rich layers have darkened dramatically. This paper proposes that the degradation of Emerald green (Cu(C2H3O2)2·3Cu(AsO2)2, copperacetoarsenite) – the main green pigment used in this painting – is a significant factor in the cause of the darkening. Electron backscatter images reveal that the Emerald green particles are shown different degrees of degradation: from partially to completely disintegrated. Elemental maps show that arsenic is distributed throughout the paint cross section, with relatively higher concentrations around iron- and aluminium-containing particles, and in the varnish layer. Imaging-Fourier-transform infrared microscopy detects copper soaps in the degraded Emerald green-containing layers. Analytical data from four paint cross sections strongly suggest that Emerald green reacts with free fatty acids derived from the binding medium forming copper soaps and mobile arsenic-based species. Chemical laboratory experiments fully support this hypothesis. Emerald green and palmitic acid in chloroform form copper palmitate and arsenic trioxide (arsenolite, cubic) under room temperature and normal light conditions. The degradation of Emerald green particles in Descente des vaches has resulted in a loss of light-reflecting surfaces and in newly formed compounds in the paint, both contribute to the colour change from green to brown.  相似文献

��[Purpose/significance] Reviewing and combing the development process and research status of library resource discovery system has important theoretical and practical significance for promoting deep integration and innovation of resource discovery system and library development.[Method/process] Based on China Knowledge Network (CNKI), Web of Science, Emerald Insight, Elsevier, Taylor & Francis SSH and other academic databases, the paper summarized the theoretical research, system selection, deployment implementation, service promotion, effectiveness evaluation and impact research of library resource discovery system by content analysis and case study.[Result/conclusion] The research results demonstrate that the resource discovery system is applied rapidly in the library. The research process of resource discovery system has obvious periodicity and stage. There are differences in the evolution of resource discovery systems at home and abroad. The research content is practical and the theoretical depth is insufficient. Research methods are mainly case studies and questionnaires, and quantitative research methods are few. Therefore, library resource discovery system should be deeply integrated with the library service, expand the scope of research and strengthen the research depth, and strengthen the research on the user profile of the resource discovery system.  相似文献

The purpose of this article is to reflect on the development of an Erasmus Mundus Digital Library Learning (DILL) program to understand the impact of the changes in technology on the role, skills and competencies of the digital librarian in contemporary society. This reflective article is based on the writer’s experience as a participant observer of the DILL program on its 10?years of development. A literature review was also employed to gather information from scholarly articles that were analyzed to help answer the research questions. Analysis of data followed a thematic approach where key ideas were identified and grouped together into themes that have been used to structure the discussions in the article. The discussions in this article have implications for further developments of education for information, particularly relating to the development of digital library learning programs in different contexts. Any effective digital library program should focus on content within a specific context, with required technology and a unique digital library education curriculum that is separate from LIS syllabi. The program may also be more effective if its curriculum content is designed to evenly assess the professional knowledge, generic skills and specific personal competencies of today’s digital librarians.  相似文献

Because the definition of content has expanded to include everything from text, graphics, audio, video, data, or any combination of these, determining the right mix of content to ensure relevance and profitability requires publishers to pay significantly more attention to the needs of their audience. This article guides publishers through the content strategy development process and shows how decisions made regarding content strategy influence the publisher??s content management and distribution functions as well. The article also includes a detailed list of the latest in content creation, management, production, and distribution trends, along with a clearly stated implication for each.  相似文献

This article describes the development of a faculty–librarian collaborative project that integrated discipline-specific information literacy into an upper-level psychology class. The instruction involved a case study technique in order to increase student engagement in a content area while helping students gain needed information literacy skills that meet professional guidelines. We found that employing this approach enhanced instructor ability to more fully and meaningfully engage with students within a more comfortable classroom atmosphere. This method may be easily adapted to other disciplines as it allows for much creativity and selection of course-relevant themes.  相似文献

This article traces the development of news as programming content in Philippine radio from the 1960s to the present. Two radio stations, DZRH and DZBB, were chosen for the study. Aside from their popularity among Metro Manila listeners, they are also similar in content (news and information-oriented programs) and have long histories. The case studies show the socio-political, regulatory, economic, and technological influences on the metamorphosis of DZRH and DZBB into news-oriented radio stations. Attention was given to the changes in news program format, news production, and the ratings and advertising of the two stations.  相似文献
