Two neolithic cases of Hyperostosis frontalis interna

Bone nodules resulting from Hyperostosis frontalis interna (HFI) were observed on the endocranial surface of the frontal bone of two elderly females in excess of 50 years of age coming from the excavation of the Neolithic hypogeum of Boileau (Vaucluse, France). These observations constituted the first evidence for HFI in the Neolithic periods in Europe. Copyright © 2004 John Wiley & Sons, Ltd.     

Technological examination of Neolithic-Bronze Age pottery from central and southeast Europe and from the Near East

Scanning electron microscopy is used to examine sequences of pottery sherds from central and southeast Europe, Greece and the Near East spanning the period from the Neolithic to the Bronze Age, in order to obtain information on the ceramic technologies employed in antiquity. On the basis of the vitrification observed and the chemical composition, the types of clay and firing procedures (temperature and atmosphere) employed in the manufacture of the pottery are defined. Two under-lying trends in the associated ceramic technologies are thus identified. The first is based on the use of non-calcareous or “unstable” calcareous clays fired in a reducing atmosphere at temperatures below 800 °C and the second on the use of “stable” calcareous clays fired in an oxidizing atmosphere at temperatures in excess of 800 °C.     

Accurate identification of the pastry contained in a ceramic pot excavated from Jurou Li's grave from the Jin dynasty (1115–1234 ce) in Xi'an,Shaanxi, China

In order to identify accurately the circular object contained in the ceramic pot excavated from Jurou Li's grave of the Jin dynasty (1115–1234 ce ) in Xi'an, Shaanxi, China, mass spectrometry was applied to determine the amino acid sequences of the residual proteins extracted from the sample, after preliminary starch grain analysis. The sequences were searched against a standard protein sequence database. The proteins extracted were identified as originating from domesticated barley (Hordeum vulgare), soybean (Glycine max), and fermentative microorganisms (Kluyveromyces lactis, Lipomyces starkeyi, Wickerhamomyces ciferrii, Nadsonia fulvescens and Zygosaccharomyces rouxii). These findings indicate that the extremely degraded object in the ceramic pot was made from barley by fermentation with the addition of soy sauce, providing direct evidence of culinary culture in the Jin dynasty.     

The Burial Rite of the Early Scythian Nomads of Tuva (based on the Bai-Dag I Cemetery)*

Excavations at the Bai-Dag I cemetery, the Eerbek River valley, Tuva, have revealed a burial rite typical of the Aldy-Bel culture, Early Scythian period. Above-ground and underground structures, principal features of the burial rite, and burial goods are described with regard to sex and age. Basic trends in the evolution of early nomadic funerary ritualism in Tuva are reconstructed.     

Composite Bows from Uch-kurbu in Kyrgyzstan

The article addresses the topic of composite bows from nomadic sites in Tien Shan and Zhetysu. Horn plates from bows discovered in 2008–2009 at Uch-Kurbu on the Tosor River, the Issyk-Kul Depression (Kyrgyzstan), are described and analyzed. The original design of the wooden core of the bow and the location of horn plates thereon are reconstructed. Based on our earlier classification of weapons, these are composite bows of the Xiongnu-Xianbei period. Two subtypes are identified, based on the design of plates at the ends of the bow. Evidently, composite bows with end, medio-lateral, and medio-frontal plates were the most efficient range weapon of the period.     

An Experimental Technological Study of Upper Paleolithic Kostenki-type Figurines

Principal stages in the manufacture of zoomorphic, polyiconic, and anthropomorphic Upper Paleolithic figurines are reconstructed. General factors determining their characteristics include universal conventions of representation and the limited set of technological operations available, whereas local factors include specific ways of processing materials and combining artistic techniques, the manner of individual masters, technological faults and accidents, as well as taphonomic processes.     

Comparison of the Different Types of Qinghua Porcelain from Jingdezhen in the Yuan Dynasty of China (ad 1271–1368) by Micro X‐ray Fluorescence Spectroscopy (μ‐XRF) and Microscopy

The Yuan Qinghua porcelain produced in the city of Jingdezhen, in China, mainly includes the gaudy blue type, a blue–grey or grey‐coloured type and the type featuring a blue colour with a slight amount of grey. For a long time, only the gaudy blue type was focused on and discussed, while the other two types, which contain equally important information with regard to recovering the manufacturing technology of Yuan Qinghua, were always ignored by scientific researchers. In this paper, by using micro X‐ray fluorescence spectroscopy (μ‐XRF), spectrophotometry and optical microscopy, all three different types of Yuan Qinghua porcelain are analysed systemically and, based on the analyses of the body, the glaze and the blue decoration, the differences in the materials and the manufacturing technologies of the three different types are discussed. This not only provides a good basis for the reconstruction of the whole picture of the manufacturing process of Yuan Qinghua porcelains in Jingdezhen, but also contributes to database‐building for the identification of Qinghua porcelain.     

The salt chimney effect: delay of thermal evolution of deep hydrocarbon source rocks due to high thermal conductivity of evaporites

Half of the topseals to the world's largest oilfields are evaporites. Rock salt has a thermal conductivity two to four times greater than that of other sedimentary rocks found in oil‐ and gas‐bearing basins. Strong heat conduction through evaporites can increase the geothermal gradient above evaporite deposits, resulting in a positive thermal anomaly and above‐average temperature while simultaneously decreasing the geothermal gradient below evaporites, resulting in a negative thermal anomaly. Most Triassic–Jurassic hydrocarbon source rocks in the Kuqa Basin, western China, are overlain by ~1500‐m‐thick Tertiary evaporites with underlying Cretaceous sandstones and mudstones. Directly measured strata temperatures indicate an obvious break in the steepness of the geothermal gradient above and below Paleogene evaporites, with a significantly steeper geothermal gradient above the evaporites. Simulations of the thermal evolution of source rocks based on data collected from well Kela‐2 indicate that if the thickness of evaporites (mainly rock salt and anhydrite rock) in overlying rocks above source rocks increases compared with the thickness of siliciclastic rocks in the overlying rocks, then strata temperatures and vitrinite reflectance in Jurassic source rocks will decrease accordingly. Our thermal simulations based on the thickness and thermal conductivity of evaporites accurately coincide with previous studies based on homogenization temperatures, hydrocarbon–water contact retrospection, and carbon isotope results from natural gases. The gas generation center located in the Kalasu Tectonic Belt today is also sealed in an evaporite‐related structural trap that formed at this time. Therefore, the speculated natural gas generation times not only correlate with the evaporite‐related structural trap formation, but the calculated maturity of deep source rocks below the evaporites also coincides with current gas reserves. And our studies can help to find the deep oils and gases under thick evaporites.     

Land acquisition induced conflicts in suburban China: a procedural perspective

Protests and opposition to land acquisition from displaced peasants for fair compensation occur on a daily basis in China and have become the most prominent social problem in rural parts of the country. Employing a procedural perspective on conflict, this paper aims to uncover the complexities and tensions that are triggered in the process by drawing on a case of a land confiscation in Jining City, a medium‐size city in Shandong Province, China. Our research shows that conflicts exist at various scales: both between the local governments and rural households and between the village officials and villagers. The paper argues that ambiguity in de jure and de facto land acquisition procedures has resulted in both an escalation of conflict and increasing inequality in the outcomes and benefits of the process. We discuss and conclude that the differences between de jure and de facto procedures in the process of land acquisition are a significant institutional barrier in the resolution of conflict in this important issue for rural China.
