An Inorganic Magnesium-based Consolidant for the Consolidation of Silica Sand (A Substitute for Weathered Sandstone): A Preliminary Exploration

ABSTRACT

Sandstone is a common sedimentary rock that is easily carved due to its weakly cemented fine grains and relatively low strength. Therefore, numerous large-scale grottoes in China are made of sandstone. However, these sandstone cultural heritage structures are often seriously damaged due to temperature and humidity changes, air pollution, biodeterioration, and repeated dissolution and crystallization of soluble salts. In general, it is imperative that a consolidant capable of providing cohesion by infilling pores between the stone grains is synthesized. In recent years, it has been reported that using organic consolidation materials for sandstone protection comes with various negative effects, such as a short lifetime, poor compatibility, and preservation damage. Using inorganic consolidation materials to protect sandstone seems to be one of the research trends for the future. Herein, this paper introduces a permeable, inorganic magnesium-based material (MMH solution) for silica sand consolidation. To assess this consolidant, the paper investigates the influence of varying molar ratios of MgO:MgCl₂·6H₂O:H₂O on properties such as penetration depth, consolidation weight, colour variation, and compressive strength. The results demonstrate that the molar ratios of MgO:MgCl₂·6H₂O:H₂O can significantly affect the consolidation performance. Additionally, it is believed that the MMH solution of MgO:MgCl₂·6H₂O:H₂O?=?5:1:16 can be successfully used for the consolidation of silica sand, as the cubic specimens’ surface micrographs show good compatibility between the consolidation product and sand grains. Experiments (i.e. weight loss rate and mineralogical compositions analysis) are performed to evaluate the cubic specimens’ water resistance properties after being immersed in water. Furthermore, the consolidation material’s failure mechanism as a self-sacrificing material is preliminarily analyzed. Results indicate that MMH solution is a promising conservation material that shows great potential for consolidating severely weathered sandstone.

教育科技用户对因特网使用情况的调查分析

文章是１９９８ 年国家科学技术部的项目《中国科技电子信息资源开发与利用研究》的一部分,通过分析国内几家教育科研单位网络用户的构成及使用因特网的基本情况,发现对于这部分教育和科技界用户来说,通过因特网查询资源已经占居重要地位,仅次于使用图书馆。文章认为图书馆在提供高质量的中文信息资源方面应该发挥更积极和更重要的作用。     

《醉翁谈录·舌耕叙引》发微

罗烨《新编醉翁谈录》甲集卷一《舌耕叙引》关系到宋代说话艺术的许多问题,是我们研究宋代说话的重要文献。本文对《舌耕叙引》的《小说引子》、《小说开辟》二篇作了比较细致的解读,并指出,宋代可能并不存在纯粹白话写作的所谓“话本”,而通俗文言传奇实为比较普遍的“话本”形态。

Effects of the New Public Management (NPM) and Austerity in European Public and Academic Libraries

The changing information landscape calls for a new leadership, new competences, and new approaches to library services. In today’s information age, information literate citizens must be able to assess the reliability of information, making information literacy instruction an important task for libraries. In this paper, five researchers present data from interviews they carried out with library leaders from Germany, Romania, Finland, UK, and Norway. The experiences of the library leaders were different, reflecting varying levels of economic austerity, and how closely each country adheres to New Public Management (NPM)-theory and practice. However, they also show how NPM and reduced budgets can lead to a greater and better cooperation.     

Virtual and Valued: A Review of the Successes (and a Few Failures) of the Creation,Implementation, and Evaluation of an Inaugural Virtual Conference and Monthly Webinars

Planning and implementing online professional development opportunities is challenging but attainable. This paper explains how a group of librarians from different institutions worked to plan, market, implement, and evaluate monthly webinars as well as an inaugural online conference, despite never meeting in person. The web conferences began in-state and grew to include presenters and attendees from across the nation. A review of available web-conferencing technologies will be provided, including free and open-source options. This paper includes details about the planning process, including subcommittee collaborations, social media marketing, and day-of logistics. Failures during event planning and execution—and tips to avoid them—will be discussed, as well as next steps looking forward.

Use of on-line databases by faculty members and research scholars of Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), New Delhi (India): A survey

The study is focused on finding out the level of use of on-line databases by faculty members and research scholars of the Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), Delhi (India). Both are Central Universities and are funded by the University Grants Commission (UGC). A well-structured questionnaire was administered to faculty members and research scholars of the JNU and JMI to collect data regarding the use of on-line database. The survey reveals that all of the faculty members and research scholars are aware of the availability of on-line databases and largely use them for reference purposes in their research work and studies. The degree of usefulness and utilization of on-line databases is high among the universities' faculty members and research scholars. The survey further reveals that the respondents from both universities are aware of the search options for accessing on-line databases. It is also found that a large number of respondents of JNU and JMI are using field searching and Boolean operators to access information from on-line databases.

学术期刊开放获取出版模式探析——由使用学术期刊数据库引起的思考

学术期刊的数据库出版模式不能完全满足科研人员的科学交流需求,数据库涨价对图书馆造成较大影响,"独家协议"给期刊社带来负面效应,而开放获取出版模式可在一定程度上弥补这种不足。影响学术期刊开放获取发展的除了科研人员、期刊社、政府部门等对学术期刊实行开放获取的态度外,开放获取平台在其发展过程中也扮演着重要角色。
