Induced metal-ion exchange in excavated human bone

Excavated human bone was exposed to aqueous solutions containing high concentrations of a single added metal ion in order to examine the extent of introduction of contaminating materials during burial. Variables included pH, temperature, ion concentration, state of bone (whole or crushed), structure of buffer, and counterion. Calcium and sodium showed little increase, and even a decrease in some cases. Strontium, zinc, lead, and magnesium showed large increases probably through heteroionic replacement of calcium. Manganese, aluminum, and potassium showed increases, particularly under neutral conditions, probably through infiltration into voids and defects.     

中国古墨与现代墨元素成分研究

对中国古墨（汉墨、明墨与清墨）与不同产地的现代墨元素成分作了对比分析。用离子背散射测定墨中常量元素C、N、O的含量,用质子激发X荧光法测定微量元素K、Ca、Ti、Cu、Fe等10种元素的含量。实验结果表明,古墨中微量元素K、Ca的含量比现代徽墨、沪墨高10倍以上,而现代徽墨与沪墨中元素N和An的含量也有明显的差别。

Structural Assessment of Companhia Aurífícia,a 19th Century Industrial Building Located in Northern Portugal

Companhia Aurifícia is located in Porto, Portugal, and was founded in 1864. It was a pioneer factory in the industrial production, casting, rolling, and stamping of metallic objects and laboured for about 150 years, in areas as jewelry, manufacture of parts in silver and gold or the production, and casting of various metals. In 1866, it began laboring in Rua dos Bragas, its present location, and in 2003 ceased all activities.Companhia Aurifícia is an industrial complex including several buildings, all located in the same block. It is a precious example of the industrial architecture in Porto, where the still existent retaining walls, structures, machinery, and decorative elements make it one of the last examples of 19^th century industrial life of the city.This article aims to evaluate the safety condition of one of the buildings included in this industrial complex, in order to propose the necessary strengthening interventions.

吴江梅堰龙南新石器时代村落遗址第三、四次发掘简报

吴江梅堰龙南遗址第三、四次发掘所出土的器物表现出明显的良渚文化晚期特征,极大地丰富了该遗址的分期资料。第三、四次发掘所发现的以木桩为基础的干阑式房址与该遗址以往发现的浅穴或半地穴式的建筑风格迥异,反映了水网地区原始先民为适应环境在居住形式上的多样性。     

Age profiles of rhino fauna from the Middle Pleistocene Nanjing man site,south China—explained by the rhino specimens of living species

A total of 60 pieces of rhino materials have been identified from the Nanjing Man site. Morphologically, they belong to the species Dicerorhinus mercki. Among the materials, 40 pieces are broken bones, and 20 are isolated teeth or jaw bones (totally comprising 41 tooth units). Among the teeth, 74% are deciduous, most of them attached to jaws. Other isolated teeth are not greatly worn, meaning they were not naturally replaced, so they represent juvenile animals. Because the skeletons are completely isolated and most of them are broken, their death can not be attributed to a natural trap. Therefore, it is very probable that hominid activities were associated with rhinos at this site. Copyright © 2001 John Wiley & Sons, Ltd.     

Morphological study of the ancient dogs from three neolithic sites in China

Ancient Chinese dogs excavated at three archaeological sites and stored in the Institute of Vertebrate Paleontology and Paleoanthropology, Academia Sinica, were the object of this study (Xiawanggang site, 5000–6000 years BP; Keshengzhuang site, 3000–4000 years BP; Shangsunjia site, Bronze age). During these periods, there were large morphological variations in Chinese dogs beyond a single dog class, as with Jomon dogs. Dogs with a large ‘stop’ were already present in China but not in Japan. At the Keshengzhuang site, middle to large class dogs were also excavated. At least three types were confirmed within these dogs. In the aged dog in Xiawanggang, antemortem loss of many teeth was observed suggesting active use of the teeth and it is possible that this dog was used for hunting as were the Japanese Jomon dogs. © 1998 John Wiley & Sons, Ltd.     

杭州出土白瓷制作年代与产地的研究

近年来,杭州出土了一批白釉瓷器残片,特别是一些具有定窑风格的白瓷样品引发了众多考古工作者和古陶瓷爱好者的关注与浓厚兴趣。为探究其制作年代和产地,采用热释光技术和X射线荧光无损分析技术相结合的方法对一批杭州出土具有定窑风格的白瓷样品进行了检测分析。测试结果表明,这批白釉瓷片样品制作年代约处在北宋末年到南宋早期,胎的化学组成中Al₂O₃含量较高,最低24.78%,最高达33.06%,具备北方瓷器特点;胎中微量元素Rb、Sr、Zr含量的比例以及钙镁碱釉的特征与河北曲阳定窑极为相似。综合文献及其它人文考证,这批杭州出土的白瓷应该为北宋晚期至南宋早期产自于河北的定窑瓷器。此分析结果也将为研究宋金贸易及文化提供科学依据。
