An Approach to the Diagnosis of Craniofacial Fibrous Dysplasia from the 2500‐Year‐Old Remains of a Skull from Ancient China

A human skull, buried about 2500 years ago in a Bronze Age cemetery at Jinggouzi, a site of an important ethnic group in ancient China, appeared to have characteristics of fibrous dysplasia. The CT images indicated a reduction in bone density and relatively homogeneous lesions. More features were revealed using CT reconstruction techniques. Lesions seen in low‐magnification images using a 3D deep‐field microscope had an irregular honeycomb‐like structure. At higher magnification, the trabeculae morphology and the gaps between the trabeculae were irregular and varied in size and shape. Paraffin‐embedded specimens stained with HE showed trabeculae with tortuous irregular arrangements varying in shape and width. The irregular trabeculae of woven bone has been described as having fibrous dysplasia. Molecular analysis of the GNAS gene indicated no mutation. This provides a non‐invasive approach for us to make more comprehensive diagnoses and to assist research into ancient human diseases.     

陕西子洲出土商代青铜容器铸造工艺观察分析

2010年11月,陕西省子洲县裴家湾镇关王岔村出土了6件青铜容器,包括尊、瓿、盘、觚、鼎、提梁卣各1件。本文通过对铜器上遗留的工艺痕迹进行肉眼观察,对铜器的铸型设计、芯撑情况、浇注位置等铸造工艺环节以及铸后加工的细节进行了初步的判断和复原,指出该批铜器的铸造工艺与安阳出土的殷墟前期同类器物基本相同,这一结果对认识和揭示这批青铜器的学术价值具有重要的意义。     

What can pollen grains from the Terracotta Army tell us?

The provenance of more than 2200-year-old terracotta warriors and horses in the Qin Shihuang Mausoleum is still a mystery, even though some researchers have inferred that the terracotta figures were produced near the mausoleum. The sporomorphs (pollen and spores) extracted from terracotta fragments of a warrior and a horse and compared with those obtained from soil samples from the Qin Dynasty layer in Pit No. 2 of the Qin Shihuang Mausoleum indicate that the pollen spectrum from the terracotta horse is different from that of the warrior, but similar to the local soil samples. Herbaceous pollen was dominant in the warrior sample, while arboreal pollen predominates in the horse and soil samples. Palynological evidence suggests that the terracotta horses were produced at a locality near the mausoleum, while the warrior came from a site which was further afield.     

冀北地区东周时期北方文化青铜短剑研究

冀北地区是中国北方青铜文化的一个重要分布区,也是北方文化和中原文化的交错地带,其文化遗存非常丰富,尤其是东周时期的青铜短剑遗存最为集中,而且文化因素极其复杂。本文在对该地区发现的青铜短剑进行类型学分析的基础上,结合前人的研究成果,试图揭示这些复杂的文化面貌中所含的各种文化因素。     

地理资源造成史前南北陶器装饰风格的差异

新石器时代,南北陶器装饰已出现不同面貌,大体说来,黄河中上游为一种,表现为彩绘的样式：长江中游为一种,表现出素面刻划的特征。造成差异的原因,地理资源即无机质矿物颜料的多寡是第一位的,这一推论大体符合彩陶分布状况,和历史献记载以及现代探矿资料。     

大地湾地画新考

大地湾地画是我国迄今已知最早的建筑绘画作品,众多学者曾先后著文对地画含义及功用进行释读。本文通过对上部人物、下部动物及人物左手动作的分析,认为该地画是父系社会阶段体现“求丰育”观念,与巫术思想无关的装饰画。     

介绍几件馆藏清代纸币

咸丰年间,清政府为了解决财政上的困难,发行了大清官票和大清宝钞,但由于发行过滥,造成通货膨胀、纸币贬值,引起百姓的不满和抵制,不得不于同治年间停止了纸币的制造和发行。本文介绍了河北大学博物馆收藏的几件清代官票和宝钞。     

黄陵寨头河战国墓地相关问题探讨

本文探讨了寨头河墓地的布局及墓葬特征、年代、族属等相关问题。研究表明,寨头河墓地的年代集中在战国早中期,个别墓葬略有早晚,其文化面貌复杂、多元因素共存,既包括了西戎文化因素、三晋文化因素,又包括少量的北方系青铜文化的因素,个别遗物与寺洼文化或有渊源关系。但是无论如何,寨头河墓地的文化内涵主体是以"铲足鬲"及各式杂色陶罐为载体的戎人遗存,它是一处与魏国关系密切的戎人墓地。     

第二轮修志的五大优势述评

第二轮志书编纂与首轮相比,在客观上具有五大优势：1．以国务院颁布《地方志工作条例》为起点,省市县三级政府纷纷颁布相关法令,开创依法修志新局面;2．各地认真总结首轮修志经验教训,为第二轮修志营造一面成败得失的镜子;3．众多方志理论著作出版,为第二轮志书的高质量引领航向;4．一批批日记、月报、月志、月鉴、年鉴等地情书出版,为第二轮修志储备了大量基础资料。5．方志界运用多种措施着力培养修志人员,方志队伍整体素质日益提高。     

Full-Scale Experimental Verification of Soft-Story-Only Retrofits of Wood-Frame Buildings using Hybrid Testing

The FEMA P-807 Guidelines were developed for retrofitting soft-story wood-frame buildings based on existing data, and the method had not been verified through full-scale experimental testing. This article presents two different retrofit designs based directly on the FEMA P-807 Guidelines that were examined at several different seismic intensity levels. The effects of the retrofits on damage to the upper stories were investigated. The results from the hybrid testing verify that designs following the FEMA P-807 Guidelines meet specified performance levels and appear to successfully prevent collapse at significantly higher seismic intensity levels well beyond for which they were designed. Based on the test results presented in this article, it is recommended that the soft-story-only retrofit procedure can be followed when financial or other constraints limit the retrofit from bringing the soft-story building up to current code or applying performance-based procedures.
