Evidence for Spanish influence on activity induced musculoskeletal stress markers at Pecos Pueblo

In the present study, hypotheses regarding the effect of Spanish contact on some habitual activities among the indigenous population of Pecos Pueblo, New Mexico, are tested using analyses of upper body musculoskeletal stress markers (MSM). Historical records demonstrate that the Spanish desired maize, animal hides, woven cotton mantas, and labour from the Puebloan Indians of this area. Therefore, it is hypothesized that a comparison of MSM data from pre- and post-Spanish contact groups at Pecos would display evidence of intensification of activities related to the procurement of these goods. The MSM data from this research do support the contention that Spanish contact had an effect on habitual activities performed by both sexes; however, the number of muscles demonstrating a statistically significant difference over time is limited. Yet trends in the mean MSM expression as well as rank order of these muscles and others uphold the hypothesized increase in maize production and processing as well as an increase in burden bearing. No evidence is found to support an increase in weaving activity. © 1997 John Wiley & Sons, Ltd.

Geophysical and Archaeological Investigation of the Survivor‐Camp of the Antelope (1783) in the Palau Islands,Western Pacific

Survivor‐camps were an unavoidable and particular category of terrestrial shore‐camp when European scientific, mercantile and imperial interests began to impinge significantly on the islands of the Pacific Ocean. In 1783 the packet Antelope was wrecked in the Palau Islands and the account of the ‘new’ archipelago, first published in 1788, was, after Cook's voyages, the most popular Pacific text in the late‐18th century. The results of archaeological and geophysical research at the camp reported here contribute to a nuanced account of early culture contact and of survivor‐camp behaviour, demonstrating the significance of shore‐camp remains for understanding maritime societies. © 2010 The Authors     

Wettability alteration of caprock minerals by carbon dioxide

One of the critical factors that control the efficiency of CO₂ geological storage process in aquifers and hydrocarbon reservoirs is the capillary‐sealing potential of the caprock. This potential can be expressed in terms of the maximum reservoir overpressure that the brine‐saturated caprock can sustain, i.e. of the CO₂ capillary entry pressure. It is controlled by the brine/CO₂ interfacial tension, the water‐wettability of caprock minerals, and the pore size distribution within the caprock. By means of contact angle measurements, experimental evidence was obtained showing that the water‐wettability of mica and quartz is altered in the presence of CO₂ under pressures typical of geological storage conditions. The alteration is more pronounced in the case of mica. Both minerals are representative of shaly caprocks and are strongly water‐wet in the presence of hydrocarbons. A careful analysis of the available literature data on breakthrough pressure measurements in caprock samples confirms the existence of a wettability alteration by dense CO₂, both in shaly and in evaporitic caprocks. The consequences of this effect on the maximum CO₂ storage pressure and on CO₂ storage capacity in the underground reservoir are discussed. For hydrocarbon reservoirs that were initially close to capillary leakage, the maximum allowable CO₂ storage pressure is only a fraction of the initial reservoir pressure.     

Paouté and Aiaouez: A New Perspective on Late Seventeenth-Century Chiwere-Siouan Identity

A fine-grained spatial and temporal analysis of relevant seventeenth-century French documents reveals that from circa 1650 to 1685 the two terms principally associated with the Ioway, Aiaouez and Paouté, were consistently applied to geographically distinct branches of that tribe. The conflation of these two terms after circa 1700 is the product of both changes in the contact-period cultural landscape and the manner in which it was defined. This conclusion has importance for the use of these accounts as analogues for reconstructing Oneota tradition social organization and highlights the value in applying contemporary theoretical perspectives and analytical techniques to ethnohistoric data.
