On containers: A forum. Introduction

This forum, involving anthropologists, archaeologists and historians, lays out the theoretical groundwork for a deep history of the container. By isolating its contents from transaction, and by enabling the manipulation of time, the container serves as an engine of history.

Gas breakthrough pressure for hydrocarbon reservoir seal rocks: implications for the security of long-term CO2 storage in the Weyburn field

This paper reports a laboratory study of the gas breakthrough pressure for different gas/liquid systems in the Mississippian‐age Midale Evaporite. This low‐permeability rock formation is the seal rock for the Weyburn Field in southeastern Saskatchewan, Canada, where CO₂ is being injected into an oil reservoir for enhanced recovery and CO₂ storage. A technique for experimentally determining CO₂ breakthrough pressure at reservoir conditions is presented. Breakthrough pressures for N₂, CO₂ and CH₄ were measured with the selected seal‐rock samples. The maximum breakthrough pressure is over 30 MPa for N₂ and approximately 21 MPa for CO₂. The experimental results demonstrate that the Weyburn Midale Evaporite seal rock is of high sealing quality. Therefore, the Weyburn reservoir and Midale Beds can be used as a CO₂ storage site after abandonment. The measured results also show that the breakthrough pressure of a seal rock for a gas is nearly proportional to the interfacial tension of the gas/brine system. The breakthrough pressure of a CO₂/brine system is significantly reduced compared with that of a CH₄/brine system because of the much lower interfacial tension of the former. This implies that a seal rock that seals the original gas in a gas reservoir or an oil reservoir with a gas cap may not be tight enough to seal the injected CO₂ if the pressure during or after CO₂ injection is the same or higher than the original reservoir pressure. Therefore, reevaluation of the breakthrough pressure of seal rocks for a given reservoir is necessary and of highest priority once it is chosen as a CO₂ storage site.     

Storage adaptations among hunter–gatherers: A quantitative approach to the Jomon period

Food storage economies among hunter–gatherers have been fundamentally important in research within anthropological archeology. It is well recognized that food storage was a key element in the evolution of hunter–gatherer societies. This paper examines storage facilities utilizing a digital planimeter to evaluate the volume and morphology of storage pits in the Jomon period (ca. 13,750–500 cal. BC). Quantitative analysis of Jomon storage pits shows temporal and spatial variability in terms of size. This research demonstrates that the quantitative analysis of storage pits is an effective way to improve our understanding of storage and its role in the Jomon economy in particular and subsistence adaptations in general. Thus, this approach has potential applications to other storage economies worldwide.     

银纳米薄膜试片在博物馆藏展材料评估筛选中的应用

Oddy测试法是一种最为常用的评估材料是否适合博物馆文物储藏与展示的测试方法,其缺点在于采用活性低的块状金属试片,需要28天的测试周期,同时试片表面平整度以及人为主观因素会影响目测结果的准确性.本工作制备了银纳米薄膜试片替代Oddy测试法中块状金属试片,以半径10mm玻璃圆片为基质,银薄膜厚度约为200～220nm.实验结果表明,采用银纳米薄膜试片后,腐蚀现象在14d后可充分显现并分化,延长至28d时腐蚀现象基本无大变化,有效的缩短了测试周期.同时尝试结合数码图像采集技术,有利于进一步的腐蚀现象数据化分析研究工作,从而得到更加客观准确的测试结果.     

Caching your savings: The use of small-scale storage in European prehistory

Understanding of European prehistoric storage practices tends to focus on the long-term and large-scale storage of cereals from the Neolithic onwards. In addition, storage is often associated with the development of sedentism and social complexity. Through the use of anthropological and ethnographic data this paper demonstrates that storage by both hunter-gatherers and farmers is more complex. New storage categories, such as closed and open caches, and portable storage, are suggested as ways of understanding whether similar storage practices were used during European prehistory. We learn that although direct evidence for storage is difficult to find in the archaeological record, a combination of ethnographic data and indirect evidence demonstrates that storage, especially this use of small-scale storage, was practiced in prehistory. In the conclusion, this paper demonstrates that storage during the Mesolithic (11,300-6000 BP) would have played a vital role in the lifeways of hunter-gatherers and that for the Neolithic (6000-4500 BP) the use of small-scale storage of a variety of foods would have been equally important as the storage of grain.     

Dwelling(s) in a north‐west Arabian oasis: decoding residential architecture at Taymāʾ

The definition of an ancient, autochthonous north‐west Arabian residential architecture is still a major void in the archaeology of the region. This preliminary case study is intended to shed some light on this “blind spot” by presenting and analysing the architectural complex E‐b9 from Taymā? (c. fourth/third century BCE until the first/early second century CE). A meticulous study of the architecture identified a modular concept as a key to understanding the complex. Furthermore, underlying patterns of household organisation can be deduced from the architectural remains resulting in the definition of potential household units. Those are indicated by a set of activity areas which are congruent with patterns of accessibility and the use of specific wall types. These findings provide insights into the organisation of households and daily life in the oasis of Taymā?, and may help to define local or regional traditions in the future.     

The implications of water storage for human settlement in Mediterranean waterless islands: The example of Pantelleria

Abstract

Consistent water supply is a common issue in the history of Mediterranean civilizations, where hydraulic solutions, such as cisterns, wells, reservoirs and aqueducts, were adopted for private and public supply. In this context, the island of Pantelleria, where surface freshwater is virtually non-existent, represents a unique case for understanding human–environment interaction in waterless environments. Here, in historical times, year-round water supply was only possible through the storage of rainwater in underground cisterns. An intensive field survey carried out across the island led to the discovery of hundreds of cisterns dated from the Punic and Roman periods to the present day. The study of the spatial distribution of the cisterns was compared with archaeological data on the island to gain new insights on historical settlement and demographic patterns. The present work focusses on a semi-quantitative assessment of water storage on the island of Pantelleria based on the evaluation of potential volumes of stored water for different periods. Data available for cisterns in Pantelleria have been analysed and compared with those from coeval Mediterranean regions. Calculations on the seasonal fluctuation between water demand and supply have been estimated to evaluate the efficiency of such system for sustaining human population and subsistence activities through time.

Omstrede Land – Die Historiese Ontwikkeling van die Suid-Afrikaanse Grondvraagstuk, 1652-2011

Abstract

This article aims to analyse the water policy of the French Protectorate in Morocco (1912–1956). After the proclamation of the protectorate, actions on the part of the new rulers affected both the modern and traditional water sectors. The authorities aimed to regulate water resources to help economic growth and favour the settlers living in the occupied areas. On the management side, they tried to adapt traditional institutions and practices to those of metropolitan France, while respecting tradition to some extent. During the first half of the 20th century, these colonial interventions caused profound changes in the established order, which can still be seen at the heart of water management systems used today in this part of the Maghreb. For the purposes of this article, we have adopted evolutionary and institutional theories and applied a methodology based on historical and anthropological analysis, with contributions from the fields of law, economics and geography.
