Salt crystallization is recognized as a major cause of damage to porous building materials, threatening the sustainable preservation of our valuable built heritage. Unfortunately, the crystallization behavior of the detected salt mixtures is complex and not fully understood. While the deliquescence points of single salts are well documented, this is not the case for salts in a mixture where one is confronted with the presence of different cations and anions. In this paper the salt content of the murals and the limestone tracery of the main entrance porch from the sixteenth century church of St. James in Liège, Belgium is investigated and related to the climatic conditions of its environment. Concerning the salt load, the research consists of hygroscopic moisture content measurements, quantitative ion analyses, and the prediction of phase equilibria using the thermodynamic model ECOS/RUNSALT. This model can predict the salt crystallization sequences of a particular ion mixture. The output is mathematically evaluated with collected temperature and relative humidity data, which enables the calculation of the number of salt crystallization–deliquescence cycles. The results show that even small amounts of salts can cause damage over a long period of time when the environment causes frequent cycles of crystallization–deliquescence over time. It is shown how a mixture of small amounts of (double) salts, including hygroscopic ones, can have a significant effect on the decay of historic building materials in the case of daily changing climatic conditions and periods of extreme drought. As a result, the crystallization of double salts and hygroscopic salts such as calcium nitrate cannot be ignored. The scientific method and the results are described. 相似文献

ABSTRACT This memoir is my personal story about how I created and came to curate on the International Counterculture Archive collection, which is held in the Global Resources Center of the George Washington University’s (GWU) Gelman library. The first person narrative relates my first encounters with Soviet rock culture and describes how I turned my initial interest into a Ph.D. dissertation on the subculture of Soviet hippies and traditions of Soviet rock music, which subsequently led to my later work as a librarian and curator. I tell the story of my initial encounters with the members of Soviet/Russian rock music subculture and other countercultural personalities and activists during my first trip to Moscow in 1993 to collect samples of Soviet rock music recordings and rock music zines for the European Division of the Library of Congress. During this formative trip I met with a number of counterculture producers and collectors who were instrumental in helping me build the International Counterculture Archive. Upon leaving the Library of Congress, I continued collecting Soviet/Russian countercultural materials on behalf of the Global Resources Center of GWU’s Gelman Library. I talk about the process of creating the Archive at Gelman library, about bureaucratic and financial aspects of this work, and about my many acquisition trips to Moscow, former Soviet republics, and East Central Europe. Much of the narrative centers on my work with Russian collectors and content producers and describes the type of materials that are included in the collection. I also describe how I built the collection of historical Soviet/Russian rock music recordings, focusing on the phenomenon of Soviet/Russian rock music zines and the history of the unique zine collection within the International Counterculture Archive. 相似文献

圣旨是研究当时社会政治、经济和文化等的珍贵资料。圣旨中的字迹在长期的储存过程中褪色淡化,导致历史信息消失而失去相应的价值。对圣旨褪色的成因进行分析,进而采用显现剂纳米二氧化硅/正丁醇分散液对字迹进行显现。采用红外光谱、扫描电镜和视频接触角考察显现剂对模拟样的影响;通过色差和力学性能评价显现剂对模拟样耐老化性能的影响。结果表明,显现剂能清晰地显现模糊不清的字迹而未明显改变圣旨的形貌和组成结构;提高了圣旨基材的力学性能和耐老化性能,对圣旨的长久保存具有重要意义。该方法对同类型的字迹显现具有一定的借鉴作用。 相似文献

馆员合作研究中馆员多样性的考察与分析——基于南京农业大学图书馆的案例分析 总被引：1，自引：0，他引：1
[目的/意义]馆员多样性和团队合作是美国ClimateQUALTM组织氛围测评中的两个重要指标,但二者的关系还没有被详尽研究。本文利用近10年南京农业大学图书馆科研合作数据,深度分析馆员合作中所体现的馆员多样性,为进一步了解图书馆组织氛围的相关特征提供依据。[方法/过程]利用馆员及其年龄、职称、学历、学科背景、岗位等馆员属性信息,将这些馆员划分成不同的类别,计算辛普森指数（simpson）和熵值（entropy）,并依此来测度科研合作中的馆员多样性,绘制合作结构图来显示科研合作的状态。[结果/结论]将馆员个体作为多样性计算中的类别,辛普森指数为0.994,熵值为0.6。按馆员年龄、职称、学历、学科背景、岗位等属性划分类别,辛普森指数处于0.82-0.997之间,熵值处于0.59-0.89之间,高辛普森指数和高熵值表明不同层次的馆员都参与了科学合作,但合作不是很集中。对一定合作强度所形成的网络结构的分析也发现,合作还处于相对比较松散的状态,没有形成固定的合作团队。高学历和高职称馆员是图书馆科研产出的重要力量,虽然馆员学科背景广泛,但图情学科背景仍是南京农业大学图书馆科研产出的重要因素。 相似文献

Several authors have proposed that a large number of unusual combinations of cited references in a paper point to its high creative potential (or novelty). However, it is still not clear whether the number of unusual combinations can really measure the creative potential of papers. The current study addresses this question on the basis of several case studies from the field of scientometrics. We identified some landmark papers in this field. Study subjects were the corresponding authors of these papers. We asked them where the ideas for the papers came from and which role the cited publications played. The results revealed that the creative ideas might not necessarily have been inspired by past publications. The literature seems to be important for the contextualization of the idea in the field of scientometrics. Instead, we found that creative ideas are the result of finding solutions to practical problems, result from discussions with colleagues, and profit from interdisciplinary exchange. The roots of the studied landmark papers are discussed in detail. 相似文献

[目的/意义]数字时代的图书馆一直在面对层出不穷的竞争者，也一直在流失用户。新一轮互联网浪潮中的知识付费成为图书馆最新的竞争者，但相关研究尚未注意到知识付费在社会知识交流中的角色与影响，也没有更进一步地再回到对图书馆事业影响的思考上去。[方法/过程]使用比较法和历史研究法，以知识付费的兴起与局限为参照展开分析。[结果/结论]知识付费兴起的原因是丰富的人才资源和扁平化的知识交流市场，当代图书馆地位受到挑战的背后是图书馆员职业主体性消解和中介性消解。图书馆应当放弃"中心"思维，重新认识现阶段的历史任务，通过图书馆和图书馆员的专业性输出来重申价值与回应挑战。知识付费尚存在不能解决信息失真和阻碍信息公平两大局限。与其他知识交流市场的竞争者相比，当代图书馆仍然具有不可替代的独特价值。 相似文献

[目的/意义] 对开放政府数据价值测量的既有实践进行梳理与比较，对未来开展的开放政府数据测量项目提供建议，并为国内学界提供参考。[方法/过程] 对国内外具有代表性的16个涉及开放政府数据价值测量的评估项目和研究报告进行梳理，比较其评估时间、主体、对象、梯度、范围和价值类型，归纳其价值测量方法，并对各类价值测量方法的特点和适用性进行说明。[结果/结论] 厘清了公共部门信息资源、开放数据和开放政府数据这三类评估对象之间的区别与联系，区分了开放政府数据价值测量的三个梯度，即产出、效果与影响，比较了不同价值测量方法的特点与适用性，并对现有开放政府数据价值测量实践存在的问题和难点进行了总结。从特征上看，评估实践总体经历了从评估公共部门信息资源利用和再利用到评估政府数据开放，从侧重单一经济价值到注重综合价值的发展历程。从方法上看，目前实践中采用的价值测量方法可从宏观上分为定量和定性两大类，定量的价值测量方法还可分为基于社会经济指标测算和基于多维度评估框架与指标体系构建两种类型。 相似文献
