Late Preceramic Peru

This paper presents a synthesis of current knowledge of Late Preceramic Peru (ca. 4450–3800 B.P.), a field of study that is less than 50 years old. A brief history of investigations and discussion of chronological systems are presented. A review of Late Preceramic achievements concentrating on subsistence economies and technology is followed by discussion of the social world of Late Preceramic Peru and current consensus and disputes regarding culture processes. Extensive long-distance exchange, farming, and social complexity are first clearly seen in the archaeological record during this time period. Nevertheless, the significance of this evidence with regard to the nature and intensity of the culture practices and processes that they represent is currently under investigation and in contention.     

Study on the source of raw material and firing technique of glazed tiles bodies in the Ming Imperial palace site,Nanjing, China

This article considered glazed tiles excavated from the Ming Imperial Palace site in Nanjing as the research object. Glazed tiles were selected and analyzed via vacuum porosimeter, thermal dilation (TD), X-ray diffraction (XRD), and energy dispersive X-ray fluorescence (EDXRF) to determine their physical property, firing temperature, phase composition, and chemical composition, respectively. Results show that the firing temperature of body belongs to the temperature range (of 950–1,100°C), whereas the water absorption and apparent porosity are large. The phase composition of glazed tile bodies is the same (predominantly quartz and mullite). However, some samples contain trace amounts of rutile, hematite, sodalite, and orthoclase. The firing temperature combined with the phase composition indicates that the raw material and firing process of glazed tile body samples have similarities, which embody of the strict and unified management system of the official kiln. The raw materials of glazed tile body in the Ming Imperial Palace site may come from Dangtu glazed kiln, whereas the rest of the samples remains to be explored. This study provides a scientific basis for understanding the evolution of glazed tile-making technology in ancient China, and is important for the protection and repair of glazed buildings in the Ming Dynasty.     

市内激励源对古建筑振动的影响

为了分析在不同激励下振动对古建筑的影响,选择苏州市省级文物保护单位——玉涵堂古建筑进行振动测试。记录了环境振动、地下轨道交通激励、人群社会活动激励和音响激励四种工况时一座两层砖木阁楼的振动信号。发现经过严格振动控制的地下轨道交通激励对古建筑振动的贡献可以忽略;环境振动和音响激励时段古建筑横向振动速度达标,而人群社会活动激励时段横向振动速度超标。从古建筑的建筑结构和功能区域划分以及人的激励形式三个方面对通常被忽视的人的因素进行了探讨,并提出了相应的减振措施。研究成果为其它类似两层砖木阁楼古建筑防护提供依据。     

The View from the Verandah: Levuka Bungalows and the Transformation of Settler Identities in Later Colonialism

The residential architecture of Levuka, Fiji, contains a diverse and well-preserved sample of what architectural historians have called the British tropical bungalow. Dating to the late nineteenth and early twentieth centuries, these small frame structures bear witness to the in situ development of a descendant colonialist identity amongst the European settlers of the port town. Analysis of the degree to which these houses conform to, and diverge from, the normative traits of the global bungalow style provides insight into the material processes of later colonialist communities and their increasingly complex cultural and social identities.     

五四时期对新史料的接受与认识

19世纪末以来新史料的大发现 ,对史学发展产生了深远影响。五四前后是接受与认识新史料的重要时期 ,王国维等人积极利用新史料进行史学研究并大力介绍新史料 ,使五四时期的中国史坛很快认识到了新史料的价值 ,这对于五四时期史学乃至 2 0世纪史学都有着非常重要的意义。     

绿色建筑概念下历史文化名城保护综合评价研究

本文以青海省同仁历史文化名城保护规划为例,从绿色建筑概念出发,结合我国国情和时代特点,利用AHP模型构建了"历史文化名城保护综合评价指标体系"。要求历史文化名城保护规划、设计遵循绿色建筑的设计方法,着眼于对地方技术及建筑历史的尊重、资源与能源的有效利用、防止环境污染,确保从建筑单体到城市整体环境逐步实现自然生态、社会生态、经济生态和历史文化生态的平衡、协调发展。使得管理部门、规划师、建筑师、业主等能够更加明确评价项目的依据以及可采用的改进措施等,也可实现从多个规划、设计方案中进行优选。     

古代文物表面常见天然有机物的显微共聚焦拉曼光谱研究

为了鉴别文物表面常见的天然有机物,采用显微共聚焦拉曼光谱技术采集了古代常用的蛋白类、多糖类、脂肪酸类、树脂类4类6种有代表性的天然有机物的拉曼光谱。通过对皮胶、桃胶、蜂蜡、棕榈蜡、达玛树脂和琥珀标准样品的拉曼光谱分析,发现蛋白类的特征振动峰位于1657cm-1、1305~1252cm-1、1033cm-1及1003cm-1附近;多糖类的特征振动峰位于1463cm-1、1328cm-1、1258cm-1、1088cm-1、977cm-1等;蜡类的特征振动峰位于1470~1350cm-1区间,1659cm-1、1303cm-1、1636 cm-1及1610cm-1;树脂类的特征振动峰位于1660~1650cm-1区间和1460~1440cm-1区间。在对6种天然有机物光谱特征分析的基础上,得出了使用拉曼光谱法可实现古代文物表面常见天然有机物种类鉴别的结论。     

White But Not Quite: Normalizing Colonial Conquests Through Spatial Mimicry

The role of mimicry in the construction and deconstruction of social identities has enriched our understanding of power relations considerably. However, as a spatial practice, mimicry has received scant consideration. In what ways can space itself become an object of mimicry? What strategies and practices are involved in this process and with what political objectives? The current paper treats these questions by analyzing processes of mimetic spatial production aiming to transform the Israeli‐occupied territory of Mount Hermon into an “ordinary” western ski resort. Yet this concerted effort produces a variety of tensions and contradictions that ultimately undo the normalization of the colonial space, comprising a test case of the convoluted ways in which mimicry of space, not merely in space, generates various forms of slippage, excess and ambivalence.     

Paper 5: Historic Mortars from the Coudenberg Archaeological Site: Characterization and Source of Raw Materials

Abstract

The characterization of historic mortars by means of a concise methodology of material analyses can provide crucial information with regard to the origin of the raw materials and the ancient mortar technology. For the analysis of the historic mortars of the Coudenberg archaeological site, the methodology consists of optical and scanning electron microscopy, simultaneous thermal analysis, and an acidic treatment. These analyses were carried out on a total of seventeen samples lifted from various areas in the site, in function of the building chronology resulting from a historic built investigation. The type of binder and aggregate as well as their volumetric ratio were determined.

Both binder and aggregate present distinctive features, which made it possible to identify the probable geological provenance of the raw materials. The observations are verified with available historical records regarding the construction of the main banqueting hall — the Aula Magna — and the use of raw materials such as limestone and sand for the production of lime and construction purposes.     

文物岩石材料劣化两类结垢物质成分 及形成机制的分析与研究

为了探讨文物岩石材料劣化结垢病害的特征和形成机理,以洛阳龙门石窟和北京西黄寺清净化城塔塔基砂岩条石为研究对象,采用全岩化学全分析和X射线衍射测试技术对两类结垢物质的成分和形成过程进行了系统分析和研究。研究结果表明,龙门石窟的结垢物是在水长期渗漏过程中对碳酸盐岩溶蚀改造沉淀后而形成的;而西黄寺清净化城塔塔基砂岩条石上的结垢物来源于砌筑砂浆(其主要物质成分为方解石),白色结垢物的形成机理为,砌缝砂浆在水渗流作用下发生溶蚀,溶蚀形成的溶液流至其下砂岩条石上经沉淀及重结晶形成结垢物。
