Abstract
Regional seismic reflection profiles and potential field data across the conjugate magma-poor Camamu/Almada–Gabon margins, complemented by crustal-scale gravity modelling and plate reconstructions, are used to reveal and illustrate the relationship of crustal structure to along-margin variation of potential field anomalies, to refine and constrain the continent–ocean boundary, as well as to study the structural architecture and nature of the continent–ocean transitional domain. The analysis reveals that the prominent conjugate Salvador–N'Komi transfer system appears to be a first-order structural element, governing the margin segmentation and evolution, and may have acted as an intraplate decoupling zone. The continent–ocean transitional domain, offshore northeastern Brazil, is characterized by rotated fault-blocks and wedge-shaped syn-rift sedimentary sequences overlying a prominent and undulated reflector (‘M-reflector’), which in turn characterizes the boundary between an extremely thinned, possibly magmatically intruded, continental crust and normal lithospheric mantle. The ‘M-reflector’ in the northeastern Brazilian margin shows remarkable similarities to the S-reflector at the West Iberia margin. In the same way, the ‘M-reflector’ is interpreted as a detachment surface that was active during rifting. Unlike the well studied central and northern segments of the West Iberia margin, however, the present study of the northeastern Brazilian margin does not clearly reveal evidence of an exhumation phase. The latter predicts exhumation of middle and lower crust followed by mantle exhumation. Increase in volcanic activity during the late stages of rifting may have ‘interrupted’ the extensional system, implying a failed exhumation phase. In this setting, the break-up and drift phase may have replaced the exhumation phase. Nevertheless, the available observations cannot discount the possibility that the ‘M-reflector’ is underlain by partially serpentinized mantle. Our study further leads to the development of a detailed conceptual model, accounting for the complex tectonomagmatic evolution of the conjugate northeastern Brazilian–Gabon margins. This model substantiates a polyphase rifting evolution mode, which is associated with a complex time-dependent thermal structure of the lithosphere. In the conjugate margin setting, asymmetrical lithospheric extension resulted in the formation of the thinned continental crust domain prior to the formation of the approximately symmetrical transitional domain.
Some emerging concepts in salt tectonics in the deepwater Gulf of Mexico: intrusive plumes, canopy-margin thrusts, minibasin triggers and allochthonous fragments

Abstract
We summarize four emerging concepts in salt tectonics in the deepwater Gulf of Mexico, selected from a longer list of concepts that have advanced significantly in the last decade. Squeezed salt stocks are common in orogenic forelands, in inverted basins and at the toe of salt-bearing passive margins. Modelling suggests that during early shortening, an inward salt plume from the source layer inflates the diapir and arches its roof. After further shortening, diapiric salt is expelled as an outward plume back into the source layer. Salt canopies are conventionally thought to advance by glacial extrusion. However, almost all modern salt canopies are now buried and can only advance by frontal thrusting. Thrusting allows the salt canopy and its protective roof to advance together, minimizing salt dissolution. Advance is by a roof-edge thrust rooted in the leading tip of salt or by thrust imbricates forming accretionary wedges. Minibasins can sink into salt if the average density of the overburden exceeds that of salt. This requires 2–3 km of burial of siliciclastic fill, yet most minibasins first sink when much thinner. Three alternative mechanisms to negative buoyancy in the deepwater Gulf of Mexico address this paradox of initiation. First, squeezed diapirs inflate, leaving the intervening minibasins as depressions. Second, when a diapir's salt supply wanes, the overlying dynamic salt bulge subsides, allowing a minibasin to form. Third, differential loading causes the thick end of a sedimentary wedge to sink faster into the salt, creating a sag. Spreading salt canopies can transport their dismembered roof fragments tens of kilometres basinward. These exotic fragments are up to 25 km in breadth and comprise anomalously old Mesozoic through Miocene sequences. Strata of the same age underlie the salt canopy or its welded equivalent, signalling lateral transport by thick salt.
Unconventional oil and gas resources and the geological storage of carbon dioxide: overview

Published: May 2011

Abstract

The ‘Unconventional oil and gas resources and the geological storage of carbon dioxide’ section of the
Proceedings
is designed to provide new insights from recent research and exploitation within these major growth areas in applied geology. Research and innovation on unconventional oil and gas have been driven by market needs – specifically concerns over oil and gas supply – as well as technological development. A cross-section of this work is highlighted in the current set of papers, covering ultra-heavy oil, shale oil, shale gas, basin-centred gas, tight gas and clathrates. Unsurprisingly, much of this research has been pioneered in North America. This work is complemented herein by some initial studies from Europe. Similarly, the geological storage of CO
2
is not simply a story of technological advance but also a response to an urgent societal imperative. Carbon dioxide sequestration is recognized as an important method for reducing greenhouse gas emissions in the near future, and is expected to have growing relevance to the oil and gas industry and the energy sector. Recent findings from current commercial carbon capture and storage projects in the North Sea and North Africa are presented and are complemented by an overview of major research programmes established in North America.
Tight gas exploration in the Pannonian Basin

Published: May 2011

Abstract
The Pannonian Basin is a mature exploration area where most of the obvious structural features have been tested and the largest conventional accumulations probably have been found. The history of hydrocarbon exploration and production in the central Pannonian Basin, Hungary, is more than 90 years old. The evaluation of unconventional hydrocarbon reserves offers an opportunity to rejuvenate exploration in this young and hot basin.
History-matching flow simulations and time-lapse seismic data from the Sleipner CO
2
plume
Authors: Chadwick R. A. , Noy D. J. 
Published: May 2011

Abstract

Since its inception in 1996, the CO
2
injection operation at Sleipner has been monitored by 3D time-lapse seismic surveys. Striking images of the CO
2
plume have been obtained showing a multi-tier feature of high reflectivity. In the medium to longer term, the topmost layer of CO
2
, accumulating and migrating directly beneath the topseal, is the main determinant of storage site performance. Fortunately it is this topmost layer that can be most accurately characterized, its rate of growth quantified, and CO
2
flux arriving at the reservoir top estimated. The latter is mostly controlled by pathway flow through thin intra-reservoir mudstones. This has increased steadily with time, suggesting either that pathway transmissivities are increasing with time and/or the pathways are becoming more numerous. Detailed 3D history-matching of the topmost layer cannot easily match the observed rate of spreading. Isotropic permeabilities result in a stronger radial component than observed and a degree of anisotropic permeability, higher in a north–south direction, is possible. The main contributor to the mismatch, however, is likely to be small but significant uncertainty in the depth conversion. Irrespective of uncertainty, the observed rate of lateral migration seems to require very high permeabilities, and is, moreover, suggestive of a topseal which behaves like a ‘hard’ impermeable flow barrier. Detailed studies such as this will provide important constraints on longer term predictive models of plume evolution and storage performance which are key regulatory requirements.
Les Leukosyriens : quelques notes d’ethnographie sinopéenne1
Authors: Dan Anca 
Published: May 2011

AbstractFollowing on from a critical ‘inventory’ of ancient evidence and modern interpretations regarding the presence of Syrians, Assyrians or Leukosyrians in the North-East of Asia Minor, I propose a geographical explanation for this strange homonymy in ancient ethnography: the presence of Syrians in Pontic and Eastern Mediterranean regions could be regarded, in Greek and Roman times, as the effect of a narrowed perception of the oekoumene. This could explain also the presence of Arabs, Chaldeans and Chalybes in the North as well as in the South of the Eastern extremity of the ancient world.
Sinopean Amphorae of the Roman Period
Authors: Vnukov Sergey Yu. 
Published: May 2011

AbstractThe main aims of this paper are to review briefly the various types of Sinopean amphorae of the Roman period, paying particular attention to newly-discovered and rare forms of these vessels, and to demonstrate their general evolution tendencies. Sinopean amphorae of the Roman period belong to two production traditions (local Hellenistic and pan-Roman), but are all made of the same fabric. The main problem when studying the Roman vessels is the lack of dated assemblages of the late 1st and 2nd centuries AD. As a result, there is a gap in the evidence between the evolution of the early Roman amphora and the vessels produced from the 3rd century onwards. Several new and rare varieties of Sinopean amphorae of this period, of both production traditions, are described in the article. They offer the opportunity to fill partly the gap between the early Roman Sinopean amphorae and the later vessels manufactured in Demirci, and to specify the typology and general evolution of the amphorae produced in Sinope.
Sinope as a Trading and Cultural Agent in Thrace during the Classical and Early Hellenistic Periods
Authors: Stoyanov Totko 
Published: May 2011

AbstractUsing a range of materials, this article aims to reveal Sinope ‐ the most developed Greek apoikia on the southern Black Sea coast from the Archaic to the early Hellenistic period ‐ as a contributor to the economic and cultural development of Thrace, especially the northeastern part. Mapping the find-spots of axe types with Thracian replicas allows us to outline the route used from the Early Bronze Age onwards from the Black Sea coast in the Sinope-Amisos area through central Anatolia toward Cilicia, Phoenicia and Palestine and confirm the opinion that the direct route across the Black Sea from Sinope to the northwest coast of the Pontus was familiar to local sea-farers before the period of Greek colonization. Sinope developed as a prosperous port of the caravan route between the Euphrates and the Black Sea from the 6th to the 4th century BC, when the polis adopted a leading role as a producer and exporter of olive oil and architectural terracottas to the markets of the northern and northwestern Pontic areas. In addition, Sinope realized the rich mineral resources of its area and was probably also an artistic centre. The economic penetration of Sinope deep into the hinterland of northern Thrace gives grounds to reassess the origins of some of the toreutic items discovered in recent decades, such as the bull-rhyton of the Borovo Treasure. Some iconographic and stylistic novelties in otherwise purely Thracian vases and other types of artefacts could be seen in the context of relations with eastern Anatolia and adjacent areas of the Near East.
Calvin and Saumur: The Case of Claude Pajon (1626–1685)
Authors: Gootjes Albert 
Published: May 2011

Given that Calvin served as an important source and authority for Amyraut during the controversies on universal grace which broke out ca. 1634, one might expect the same to be true for the polemics on (im)mediate grace surrounding the teachings of another (later) Saumur universalist, Claude Pajon. As this article demonstrates, however, the manuscript works written by, to, and about Pajon reveal that he did not shelter behind Calvin’s name—even if he believed that the latter had shared his view. The extant sources instead show that John Cameron and Paul Testard, two earlier promoters of la grâce universelle, were Pajon’s main sources of inspiration and served as his authorities. The article closes with a twofold conclusion, namely, that the marginal place of Calvin in the Pajon controversies may well be attributed to the greater acceptance la grâce universelle had gained by that time; and secondly, that one does well to recognize the existence of different currents within la grâce universelle of seventeenth-century French Protestantism.
The Lasting Echo of the Battle of Grunwald: the Uses of the Past in the Trials between the Armenian Community of Lemberg and the Catholic Patricians in 1578–1631
Authors: Osipian Alexandr 
Published: May 2011

AbstractThe article deals with the historical imagination in the burgher's milieu in the late Renaissance Polish kingdom. The main aim of the article is the investigation of the changes that occurred in the perception of the remote past. The article focuses on the mechanisms of a usable past construction. In 1578, in order to obtain equal economic rights with the dominant Catholic burghers – mostly of German origin – in Lemberg, local Armenians stated that their ancestors were invited by the Galician prince Daniel and were then settled by his son Lev/Leon (1264-1301) in Lviv at the time of the city's foundation. In 1597, in their complaint, Catholics allowed that the statement of the invitation of the Armenian ancestors was a real fact but accused "Armenian warriors" for participating in the hostile incursions led by Prince Daniel or Lev together with the Tatars in the 1250s-1280s against Poland. In this way, the magistrate won the trial in 1600. I argue that for their pseudo-historical argument Catholic patricians creatively reinterpreted some passages from Marcin Cromer's book "On the origins and deeds of the Poles" (1555, 1558, 1562, 1568, 1589). Then, Armenians changed their tactics and stated in 1631 that their noble ancestors took an active part in the wars between Poland and Teutonic Order in late fourteenth – early fifteenth centuries. Thus Armenians converted their ancestors into good patriots of Poland when the Germans were the main enemies. During the trials townspeople perceived changes in their past. It also reflects a level of historical reading in Polish history and the emergence of the Battle of Grunwald battle as part of a Polish national myth. Thus Renaissance book-printing and book-collecting directly influenced the burgher's historical imagination and their judicial argument. City elites "privatized" a book, which had been sacral property of Church, and made it their tool to use for their practical needs. They also privatized and instrumentalized the based-on-books past. The arguments used by both sides during their conflict correlated with the urban elites' aspirations to acquire noble status. It also reflects the process of transmission of high culture models – Sarmatian Renaissance – to the lower estates of the Kingdom.
1855–1911
Authors: Suslov Mikhail 
Published: May 2011

AbstractThis article explores one of the oldest controversies over Slavophile thought: the question of whether it is a form of liberalism or conservatism. The author reassesses understudied neo-Slavophile ideologists through the prism of the debates on the public sphere. The paper focuses on the popular journalist S. F. Sharapov (1855-1911) and his utopias. Sharapov and the plethora of the Slavophile intellectuals, such as N. P. Aksakov, A. A. Kireev, D. A. Khomiakov, I. F. Romanov, A. G. Shcherbatov, and A. V. Vasil'ev, worked out a project of autocracy based upon local self-government. Their project featured such elements of liberalism as humanism, freedom of conscience and the press, and toleration of the non-Russian and non-Orthodox subjects of the Empire. One of the central themes of the neo-Slavophile project was criticism of the bureaucratic imperial regime and offering proposals of comprehensive reforms. At the same time, neo-Slavophilism embraced anti-Semitism and a deep-rooted aversion to the West and Western political practices. The distinctiveness of the neo-Slavophiles consisted of the Messianic belief in Russia's uniqueness and ability to develop a 'truly liberal' political regime, in which rigorously observed Christian morality would be present alongside civil rights and freedoms. The paper argues that Slavophilism is not a repository of ready-made illiberal ideas, but a practice of social criticism, which comes up when attempts at political modernization in Russia are half-hearted or have failed.
Design, Generation, and Characterization of a 1,5-Hexadiene Bearing Two Lophyl Radicals as a Probe of the Stepwise Mechanism for the Cope Rearrangement

Abstract
The mechanism of the Cope rearrangement of 1,5-hexadienes remains controversial. Two pathways for the rearrangement of 2,5-diphenyl-1,5-hexadiene have been debated over the past several decades. The first is a concerted route that takes place via a pericyclic transition state and the other is a stepwise process via a biradical intermediate or biradicaloid transition structure. In this study, we explored a new intramolecular trapping approach to examine the possible existence of the putative biradical that might intervene in the stepwise Cope rearrangement. For this purpose, a study was carried out in which a 1,5-hexadiene, bearing two lophyl radicals at C2 and C5 positions, moieties capable of trapping a putative biradical intermediate intramolecularly, was designed, generated, and characterized both experimentally and with density functional theory.
Work and common psychiatric disorders
Authors: Henderson M , Harvey SB , Øverland S , Mykletun A , Hotopf M 
Published: May 2011

Psychiatric disorders are now the most common reason for long-term sickness absence. The associated loss in productivity and the payment of disability benefits places a substantial burden on the economies of many developed countries. The occupational dysfunction associated with psychiatric disorders can also lead to poverty and social isolation. As a result the area of work and psychiatric disorders is a high priority for policymakers. There are two main agendas: for many researchers and clinicians the focus is on the need to overcome stigma and ensure people with severe psychiatric disorders have meaningful work; however the public health agenda predominantly relates to the more common disorders such as depression and anxiety, which contribute a greater burden of disability benefits and pensions. In this review we attempt to address this second agenda. The relatively sparse evidence available reveals a complex field with significant interplay between medical, psychological social and cultural factors. Sick leave can be a ‘process’ as well as an ‘event’. In this review we propose a staged model where different risk and protective factors contribute to the onset of psychiatric disorders in the working population, the onset of short-term sickness absence, and the transition from short- to long-term absence. We also examine strategies to manage psychiatric disorder in the workforce with a view towards returning the employee to work. Our aim in this review is to highlight the complexity of the area, to stimulate debate and to identify important gaps in knowledge where further research might benefit both patients and wider society.

Published: May 2011

INTRODUCTION Primary hyperparathyroidism (PHPT) is a common condition (250 per million population per year) with significant associated morbidity and mortality. 1 Surgery is the only curative option for PHPT; results from medical treatment remain disappointing. 2 The aim of this study was to evaluate the referral patterns of patients with PHPT and identify the number of missed cases with a biochemical diagnosis of PHPT. MATERIALS AND METHODS All chemistries for Worcestershire were performed and analysed at the Worcestershire Royal Hospital. Patients with chronic renal failure were identified and excluded. Routes of patient referral were identified and missed cases documented. General practitioners (GPs) were contacted by letter for all patients not referred or treated. Outcomes of diagnosis and specialist assessment were recorded. RESULTS A total of 102 cases of PHPT were identified: 64 (62.7%) remained untreated and without a specialist referral in place, 36 (35.3%) had undergone parathyroidectomy and 2 (2.0%) were being monitored. The GP response rate was 90% (46/51). Of these, 30 (65%) were subsequently referred, 9 (20%) underwent repeat tests with a view to referral and 7 (15%) were lost to follow up. CONCLUSIONS A significant proportion of patients with PHPT remain in the community untreated and having not seen a specialist. All patients should be referred to a specialist for assessment and consideration of surgical treatment and follow-up. Improvements in GP education and referral systems are required if patients are to benefit.
Hip resurfacing revision rates: radiological audit of risk factors
Authors: Ramisetty N , Krishnan KM , Partington PF 
Published: May 2011

INTRODUCTION We performed a retrospective radiological audit of the hip resurfacings carried out in our trust over a five-year period. Abnormal cup inclination angle (CIA) and stem shaft angle (SSA) are recognised risk factors for revision in hip resurfacing. Our aims were to identify the CIA and SSA for hip resurfacings in our trust, to determine the revision rate in a CIA of ≥60° and an SSA of >0° varus, thereby identifying a high risk group for close, long-term follow up. METHODS A total of 247 patients underwent hip resurfacing in our trust between April 2003 and March 2008. The CIA and SSA were recorded. Of the 247 patients, 26 were excluded as there were no appropriate radiographs and so results were analysed for 221 patients. RESULTS The mean CIA was 47.6°. Over a third of the patients (34%) had a CIA of >50° and 13% had >60°. The mean SSA was 1.4° varus. Over two-thirds of the patients (67%) had a varus SSA. There were six revisions but one was excluded as it was secondary to infection. The revision rate was 10% in patients with a CIA of ≥60° and 1% in those with a CIA of <60° (p=0.017), and 1% in a varus and 4% in a valgus SSA (p>0.05) respectively. CONCLUSIONS The measurement of the CIA and SSA in hip resurfacings has identified a high risk group for close long-term follow up. There is already a 10% revision rate in those patients with a CIA of >60°. Hip resurfacing may generate a large revision burden in the ‘average’ surgeon's hands and all hospitals/surgeons should review their radiological outcomes critically and identify those at risk of revision.
