Damage Assessment of Unreinforced Stone Masonry Buildings After the 2010–2011 Canterbury Earthquakes

The sequence of earthquakes that has affected Christchurch and Canterbury since September 2010 has caused damage to a great number of buildings of all construction types. Following post-event damage surveys performed between April 2011 and June 2011, an inventory of the stone masonry buildings in Christchurch and surrounding areas was carried out in order to assemble a database containing the characteristic features of the building stock, as a basis for studying the vulnerability factors that might have influenced the seismic performance of the stone masonry building stock during the Canterbury earthquake sequence. The damage suffered by unreinforced stone masonry buildings is reported and different types of observed failures are described using a specific survey procedure currently in use in Italy. The observed performance of seismic retrofit interventions applied to stone masonry buildings is also described, as an understanding of the seismic response of these interventions is of fundamental importance for assessing the utility of such strengthening techniques when applied to unreinforced stone masonry structures.     

Isotopic Reconstruction of the Late Longshan Period (ca. 4200–3900 BP) Dietary Complexity before the Onset of State‐Level Societies at the Wadian Site in the Ying River Valley,Central Plains,China

During the late Longshan period (ca. 4200–3900 BP) settlements on the Central Plains of China underwent a diversification in food production technologies, which set the stage for rapid economic and social development. The introduction of novel domesticates such as rice, wheat, cattle, and sheep not only provided more food choices, but also changed ideas concerning land use, farming techniques, and the use and mobilization of large scale labor forces. To better understand the contribution that these new dietary items and practices made to shaping the late Longshan period societies, a stable isotope ratio study of humans (n = 12) and animals (n = 42) was conducted at the late Longshan period site of Wadian. The human δ¹³C and δ¹⁵N values are clustered into two distinct groups. One group of nine individuals (δ¹³C = −9.9 ± 0.7‰; δ¹⁵N = 7.5 ± 0.5‰) had a predominately C₄ diet based on millet grains with little protein input from the domestic animals. The other group of three individuals (δ¹³C = −14.3 ± 0.8‰; δ¹⁵N = 10.2 ± 0.3‰) had a mixed C₃/C₄ diet of millets and rice and were consuming sheep and cattle. The animals also displayed dietary diversity with the pigs (δ¹³C = −11.3 ± 2.5‰; δ¹⁵N = 6.9 ± 1.0‰, n = 10) and dogs (δ¹³C = −10.1 ± 1.0‰; δ¹⁵N = 7.2 ± 1.1‰, n = 7) having mostly a C₄ plant based diet (millets). In contrast, the cattle (δ¹³C = −12.8 ± 2.1‰; δ¹⁵N = 7.6 ± 0.7‰, n = 9), sheep (δ¹³C = −16.7 ± 0.9‰; δ¹⁵N = 7.6 ± 0.1‰, n = 2), and cervids (δ¹³C = −20.8 ± 0.9‰; δ¹⁵N = 5.0 ± 1.2‰, n = 10) had diets with a greater contribution from C₃ sources such as rice and wild plants. The discovery that humans and animals had different subsistence patterns indicates dietary complexity at Wadian and that rice agriculture, and cattle and sheep husbandry practices were already an important part of the local economy by the late Longshan period in the southern region of the Central Plains of China.

A NEW METHOD FOR EXTRACTION,ISOLATION AND TRANSESTERIFICATION OF FREE FATTY ACIDS FROM ARCHAEOLOGICAL POTTERY

This paper presents evidence for increased recovery of organic residues from archaeological pottery through use of a microwave‐assisted liquid chromatography protocol. C_16:0 and C_18:0 saturated fatty acids were obtained from archaeological potsherds recovered from nine Neolithic settlements in the Middle East dating between 4700 and 7300 cal bc , including materials that had not produced evidence for the survival of any lipid species through use of ‘conventional’ solvent extraction techniques. Compound‐specific isotopic analyses of C_16:0 and C_18:0 fatty acids in potsherd extracts subsequently revealed δ¹³C/δ¹²C compositions consistent with modern subcutaneous fats of wild boar and goats pastured on lands adjacent to the Jordan Valley, and residues from a modern pottery vessel used in the manufacturing of butter, cheese and yogurt in central Turkey. These results are presented as an illustration of capabilities of the microwave‐assisted recovery protocol. The reclamation of saturated and unsaturated fatty acids from archaeological pottery fragments recovered from a number of the earliest ceramic horizons in the Middle East is herewith reported, and the extraction methods and instrumental analytical techniques are described.

Several issues influencing the course of German history

The course of German history is very sinuous. German nationalism, the imbalance of the political and economic development generated by the influence of the historical and cultural traditions, the might of the Junker feudal aristocracy, the weakness of the bourgeoisie, the postwar reeducation of democratization imposed by the western allied powers on Germany, the developed education and technology, etc. are all important factors that influenced Germany’s history. __________ Translated from: Wuhan Daxue Xuebao, Renwen Kexue Ban 武汉大学学报: 人文科学版 (Wuhan University Journal, Humanity Science), No. 3, 2004     

First evidence of the production of Ginalski E5 button spurs from copper alloy in Central Europe

Ginalski-type E5 button spurs made from a Cu alloy are a characteristic attribute of the Middle Roman period in barbarian Europe. The find of part of a mould made of non-ferrous metal at the Luleč site in the district of Vyškov, Czech Republic, provided key evidence for explaining the issue of their production. The discovery of this unique artefact showed that based on current knowledge, the spurs made from a Cu alloy were also produced in the Middle Danube region and not only in Northeast Europe as had previously been thought.

Ground Penetrating Radar in the Northern Great Lakes: A Trial Survey of a Contact Period Occupation in Marquette County,Michigan

ABSTRACT

Timing, inclement weather, and limited budgets can obstruct archaeological survey efforts. Here, we ameliorate some of these with use of ground penetrating radar (GPR) at the Goose Lake Outlet #3 (GLO#3) site (20MQ140). GPR surveys to guide survey and excavation efforts in these well-drained sandy soils are limited. GPR imagery exhibited false positives; however, shovel probes, subsequent site excavation, and artifact analysis led to numerous discoveries at this protohistoric site—including glass trade beads dating to the 1630s. These discoveries solidify evidence for some of the earliest European-made trade items in the region and provide further confirmation for placement of an Indian trail and ancient travel corridor between Lake Superior and Lake Michigan. Two ¹⁴C samples obtained from moose-bone in features with trade goods fall within the expected occupation range of 1633–1668 and 1615–1647. Several anomolies, possible hearth clusters were seen on the GPR imagery; however, many features remained invisible.
