A New Energy Age in Pacific Russia: Lessons from the Sakhalin Oil and Gas Projects

A noted British specialist in Russia's economic geography and the Far East region presents a comprehensive account of the development of the onshore and offshore oil and gas deposits of Sakhalin. Following a review of early multinational activity in geological surveying and exploration during the 1970s, he charts subsequent changes in the entities formed to develop and exploit the deposits (Sakhalin-I and -II) later in the Soviet period and during the first two decades of Russian independence. These changes have responded to improved knowledge of the geology of the deposits and changing relations between the Russian central government and Sakhalin regional authorities. Also analyzed are efforts by the Russian side to overturn or otherwise modify terms of previous agreements deemed unfavorable, and maneuvering by China and Japan to secure increasing sources of supply for their markets. With Sakhalin's two core projects now entering the active production phase, the author distills a number of key issues that have shaped the development of the island's offshore hydrocarbon resources and will have a bearing on prospects for a future generation of less spectacular new projects (incremental development); he also outlines wider lessons that have been learned over the life of Sakhalin's projects.

The environment as a life support system: the case of Biosphere 2

This paper studies an attempt to replicate the Earth’s biosphere in the second half of the twentieth century with the aim of preserving and refashioning the environment as a self‐reproducing ecological system. Ecosystems dynamics framed the planet Earth as a closed system and directed scientific attention to questions of global environmental management. The image of the Earth as a spacecraft and operable in a similar way supported ideas of placing the environment in a laboratory setting. Using the case of Biosphere 2, launched in the Arizona desert in 1983, this paper studies the images of nature and environment contained in this quest to create an ecosystem and human habitat as good as, or superior to nature on Earth (known in this context as Biosphere 1). The second biosphere was designed as ‘a prototype for a space colony’ that would eventually enable its deteriorating predecessor, the Earthly biosphere, to reproduce and allow human settler societies to migrate to other planets. The paper draws on the cultural history of the ship in Western culture and on ships and spaceships as archetypes of autarkic enclosures set apart from nature. It argues that Biosphere 2 as an example of a technologically controlled endosphere advanced an understanding of the environment as a ‘life support system’ that emphasized not completeness but systems integrity, and was based on principles of functionality and replaceability. The paper will explore how notions of biospheric life support shaped demands on the natural and social environments in Biosphere 2 and Biosphere 1.     

TORSIONAL EFFECTS IN THE PUSHOVER-BASED SEISMIC ANALYSIS OF BUILDINGS

The general trends of the inelastic behaviour of plan-asymmetric structures have been studied. Systems with structural elements in both orthogonal directions and bi-axial eccentricity were subjected to bi-directional excitation. Test examples include idealised single-storey and multi-storey models, and a three-storey building, for which test results are available. The response in terms of displacements was determined by nonlinear dynamic analyses. The main findings, limited to fairly regular and simple investigated buildings, are: (a) The amplification of displacements determined by elastic dynamic analysis can be used as a rough, and in the majority of cases conservative estimate in the inelastic range, (b) Any favourable torsional effect on the stiff side, which may arise from elastic analysis, may disappear in the inelastic range. These findings can be utilised in the approximate pushover-based seismic analysis of asymmetric buildings, e.g. in the N2 method. It is proposed that the results obtained by pushover analysis of a 3D structural model be combined with the results of a linear dynamic (spectral) analysis. The former results control the target displacements and the distribution of deformations along the height of the building, whereas the latter results define the torsional amplifications. The proposed approach is partly illustrated and evaluated by test examples.     

Characterization of elemental and firing-dependent properties of Phlegrean ceramics by non-destructive ED-XRF and NMR techniques

A combination of energy dispersive X-ray fluorescence (ED-XRF) and 2D proton nuclear magnetic resonance (¹H NMR) relaxometry was employed for the characterization of two groups of similar ceramic fragments from the high-medieval production of the Phlegrean area (Miseno and Cuma, Southern Italy). Both methods are based on the use of non-destructive and portable instruments. This approach allows to correlate complementary microstructural features of ceramics, both dependent and independent of the firing technique.     

Who were the Meroites? A biological investigation into the Nubian post‐hiatus group

Scholars have identified a hiatus in the archaeological record of Lower Nubia that spans approximately 1000 years. This interval may represent a desertion of Lower Nubia by its inhabitants. Evidence of occupation did not reappear in the area until the Meroitic time period. However, the identity of the returning people has been the subject of speculation. In order to determine who the Meroites of Lower Nubia were, 20 cranial non‐metric traits were observed on six Nubian groups, representing five time periods. Two groups date to time periods immediately before (Kerma) and immediately after (X‐Group) the Meroitic period. Three additional Nubian groups (two Christian samples from different sites and Sesebi, a contemporary sample) were utilised as outgroups to elucidate a clearer picture of the relationship among the six samples. Mahalanobis D² with a tetrachoric matrix was employed for calculating biological distances among the groups. Principal coordinates analysis produced two clusters of Nubians, where the Meroitics clustered with other Nubian groups. Specific distance scores indicate the Meroites were biologically similar to individuals from the time periods prior to and after their arrival in Lower Nubia. The Meroites therefore appear to be a Nubian group returning to Lower Nubia after its desertion. Copyright © 2009 John Wiley & Sons, Ltd.     

Food Rituals and Their Social Significance in the Mid‐Second Millennium BC in the Southern Levant: A View From Megiddo

Ceremonies involving intentional burial of animals with humans are acknowledged to bear religious, social and political connotations, and we explored both the ritual activity and the social trajectory of these activities. To date, these ceremonies have rarely been examined within the context of nearby daily activities. We studied faunal remains associated with intramural burials in comparison with contemporaneous daily life in the midsecond millennium bc at Tel Megiddo, as well as comparison with concomitant extramural burials and locations of public feasts. Our study highlights the human interaction with animals that are not often treated as bearing social meaning or having interrelationships with human, the livestock animals. We demonstrate that livestock animals in the second millennium bc had a significant social role as well as economic value. The choice of animals consumed and sacrificed in these rituals is strongly related to the animal's symbolic potency and is based on the desired social message that the population aims to convey. Finally, the form of luxury food that is found in the Megiddo funerary rituals supports the hypothesis regarding the intramural burials' role in creating and enhancing social family bonds.

Migration of metamorphic CO2 into a coal seam: a natural analog study to assess the long‐term fate of CO2 in Coal Bed Carbon Capture,Utilization, and Storage Projects

This study assesses the displacement of coalbed methane by CO₂ migration along a fault into the coal seam in the Yaojie coalfield. Coal and gas samples were collected continuously at various distances in NO.2 coal seam from F19 fault. Vitrinite reflectance, maceral, and pore distributions and proximate analysis of fourteen coal samples were performed. Gas components, concentrations, carbon isotopes of 28 gas samples were determined. We examined the coal–gas trace characteristics of coalbed methane displaced away from the fault by CO₂ injection after geological ages. From east to west, away from the F19 fault, the CO₂ concentration decreased, whereas the CH₄ concentration increased gradually. The δ¹³C values for CO₂ varied between ?9.94‰ and 1.12‰, suggesting a metamorphic origin. A wider range of values (from ?9.94‰ to 20‰) was associated with the mixing of microbial carbon dioxide, isotopic fractionation during CO₂ migration through the microporous structures of coals, and/or carbon isotope fractionation during gas–water exchange and dissolution of CO₂. Away from the F19 fault, the volumes of micropores, mesopores and macropores decrease gradually. The Dubinin–Radushkevich (DR) micropore volume decreased from 0.0059 to 0.0037 cm³ g^‐1, and the mesopore and macropore volumes decreased from 0.066 to 0.026 cm³ g^‐1. The CO₂ injection can mobilize aromatic hydrocarbons and mineral matter from coal matrix, resulting in the decrease in the absorption peak intensity for coal samples after supercritical CO₂ treatment, which indicates that chemical reactions occur between coal and CO₂, not only physical adsorption.
