A Spanish Man‐o‐War in New Zealand? The 1864 wreck of Grafton and its lessons for pre‐Cook shipwreck claims

This paper considers the 1864 wreck of Grafton in the Auckland Islands, and its implications for wreck analysis and pre‐Cook exploration claims. The captain of Grafton, Thomas Musgrave, stated that the schooner was built from the wreck of a Spanish man‐o‐war, and archaeological analysis of the wreck found that the timbers are a tropical South American species, and had possibly been reused. The implications of this are clear; it is possible that timbers that originated in pre‐Cook (1769) ships lie in New Zealand, but without a full understanding of the historical and archaeological context of any such timbers, including their reuse in later ships, it is not possible to claim proof of pre‐Cook European exploration of New Zealand.     

Controlled Rocking CLT Walls for Buildings in Regions of Moderate Seismicity: Design Procedure and Numerical Collapse Assessment

Controlled rocking heavy timber walls are designed to rock on their foundations in response to earthquakes. For regions of moderate seismicity, it is proposed that this rocking behaviour can be adequately controlled using only post-tensioning, even with a large force-reduction factor and no supplemental energy dissipation. This article presents a force-based design procedure for controlled rocking cross-laminated timber walls without supplemental energy dissipation, including a method for estimating higher mode effects. Fragility analyses of three prototype walls demonstrate that the procedure can limit the probability of collapse to <10% during a maximum considered earthquake in a region of moderate seismicity.

Persistence of the cultural landscape in Campania (Southern Italy) before the AD 472 Vesuvius eruption: archaeoenvironmental data

Cultural landscapes were prominent during the Early Roman period when agronomic knowledge allowed the spread of intensive land exploitation in most of the available land. The aim of this contribution is to explore whether for the Campania region (Southern Italy) archaeoenvironmental data would support continuity or change in the cultural landscape of Roman tradition in the 4th and 5th centuries. To do so, new data from two sites located on the northern slopes of the Vesuvius, both buried by the AD 472 eruption have been investigated. Charcoal analysis, ¹⁴C dating, and chemical analysis of organic residues were carried out in order to study the landscape and the food production at these sites. The results suggest the persistence of the Roman cultural landscape until the 4th and 5th centuries in this area. The landscape is in fact strongly marked both in agriculture and woodland exploitation and management, being characterized by managed chestnut forests as well as valuable cultivations of walnut, large vineyards, olive groves, and probably orchards and crops. The integrated approach with archaeobotanical and archaeometric analyses proves to be a powerful method for the study of the past landscapes, providing a good insight into the environment. Furthermore, this study provided the most ancient evidence of chestnut silviculture for wood.     

海昏侯墓部分木质文物材种鉴定及用材分析

为了解海昏侯墓椁室木材及随葬漆木器木材种类,进而分析其用材特点,分别对木材取样进行种属鉴定。鉴定结果表明:海昏侯墓椁木为樟科(Lauraceae)桢楠属(Phoebe)桢楠(Phoebe zhennan),椁室木门为柏科(Cupressaceae)柏木属(Cupressus)柏木(Cupressus funebris),比较文献资料,推测汉代椁室常用木材即为楠,反映了汉代椁木用材的专门化;受检的随葬漆木器材种均为樟科,包含檫木属(Sassafras)檫木(Sassafras tzumu)、黄肉楠属(Actinodaphne)、琼楠属(Beilschmiedia)等,反映出随葬漆木器用材具有地域性,可能均为本地生产。     

Russian timber industry in the 1920s: on the short history of Russnorvegoles

After the Russian Revolution, with civil war and interventions, war communism (1918–1921) led to a period of great economic difficulties in Russia. The New Economic Policy was the solution, and concessions offered to Western business interests were a part of it. In the timber industry of the 1920s, the jointly Western and Soviet controlled company Russnorvegoles was an important concession. The majority of the Western interests were Norwegian, and the company was registered as a Norwegian limited liability company with seat in Oslo. The four-and-a-half-year history, involving Western interests in the operations of Russnorvegoles, is both interesting and dramatic. Profitability was undermined, and intricate currency arrangements played a significant role during the last eighteen months in which Western interests were involved. The prominent Norwegian fascist politicians Quisling and Prytz were both involved, and the latter emerged a wealthy man. Living on his means for some years following 1928, he contributed financially to the formation in 1933 of a Norwegian Nazi party (Nasjonal Samling/National Reunion). This dimension of Norwegian political history demonstrates the role that Russnorvegoles played beyond the timber industry.     

The use of predictive modelling to target Neolithic settlement and occupation activity in mainland Scotland

A central aim of Neolithic studies in Europe is to understand settlement or domestic activity of the first agriculturalists. In Scotland, the continued absence of unambiguous Neolithic settlement or domestic occupation activities on the mainland remains an unresolved issue. It is proposed that areas attractive for settlement and occupation activities may be identified by constructing GIS-based models of sites believed to be related to settlement or occupation activities, including chambered cairns, timber halls, and sites containing pit-digging episodes. Statistical analyses undertaken in this process suggest new insights into the locations of the chambered cairns, timber halls, and pits. Finalised models are constructed and desktop assessments are conducted to examine model performance. Research priorities for improving significant environmental variables driving the current models are identified.     

故宫太和殿木构件现状分析及加固方法研究

为加强对古建筑的维修保护,故宫博物院对太和殿进行了勘查,发现如下木构件问题:西山挑檐檩跨中挠度过大;三次间正身顺梁及山面扶柁木榫头位置下沉10cm;明间藻井下垂13cm,井口爬梁已经开裂.通过运用结构力学相关方法,对这些构件的结构现状进行理论分析,研究了问题产生的原因,讨论了相应的加固方案,解决了这些问题.结果表明:西山挑檐檩虽然挠度较大,但强度满足要求,不需要加固;山面扶柁木榫头下沉的原因是局部受弯强度不足,但已通过支顶解决该问题;正身顺梁榫头下沉的可能原因是材料老化,局部受拉、弯、剪强度不足,通过采用钢木组合结构进行了加固;藻井下沉的原因是木材老化,井口爬梁抗弯及抗压承载力不足,通过采用扁钢箍加固的方法进行了加固.研究结果可为古建筑保护及修缮提供参考.     

Vegetation history at the multi-period prehistoric complex at Ballynahatty,Co. Down,Northern Ireland

Palaeoecological methods can provide an environmental context for archaeological sites, enabling the nature of past human activity to be explored from an indirect but alternative perspective. Through a palynological study of a small fen peatland located within the catchment of a multi-period prehistoric complex at Ballynahatty, Co. Down, Northern Ireland, we reconstruct the vegetation history of the area during the early prehistoric period. The pollen record reveals tentative evidence for Mesolithic activity in the area at 6410–6220 cal BC, with woodland disturbance identified during the Mesolithic–Neolithic transitional period ca. 4430–3890 cal BC. A more significant impact on the landscape is observed in the Early Neolithic from 3950 to 3700 cal BC, with an opening up of the forest and the establishment of a mixed agricultural economy. This activity precedes and continues to be evident through the Mid-Neolithic during which megalithic tombs and related burial sites were constructed at Ballynahatty. Due to chronological uncertainties and a possible hiatus in peat accumulation in the fen, the contemporary environment of the Ballynahatty timber circle complex (constructed and used ca. 3080–2490 cal BC) and henge (dating to the third millennium cal BC) cannot certainly be established. Nevertheless, the pollen record suggests that the landscape remained open through to the Bronze Age, implying a long continuity of human activity in the area. These findings support the idea that the Ballynahatty prehistoric complex was the product of a gradual and repeated restructuring of the ritual and ceremonial landscape whose significance continued to be recognised throughout the early prehistoric period.
