The response of phytoplankton to climate variability associated with the North Atlantic Oscillation

Inter-annual variability in the timing of phytoplankton spring bloom and phytoplankton community structure in the central North Atlantic Ocean was quantified using ocean color data and continuous plankton recorder (CPR) data. This variability was related to the North Atlantic Oscillation using correlation analysis and multivariate auto-regression models. The initiation of the spring bloom derived from CPR phytoplankton color index data is similar to that derived from satellite chlorophyll, and exhibits a nominal correlation with the sea surface temperature (SST) and the North Atlantic Oscillation (NAO). The extrapolated spring bloom timing suggested later initiation of blooms in the mid-1980s and earlier initiation of blooms in the 1990s. The climatological phytoplankton community structure in the central North Atlantic is dominated by diatoms, except for a shift in community composition favoring dinoflagellates in August. The ratio of diatoms to total phytoplankton abundance and the ratio of dinoflagellates to total phytoplankton abundance are both closely correlated with the NAO and SST. The extended time series of phytoplankton community structure between 1985 and 2009, deduced from the time series of SST and NAO over the same interval, showed a decadal shift away from diatoms towards dinoflagellates. The linkages between the NAO, and changes in stratification and phytoplankton processes occur over a larger scale than previously observed.

Isotopic assessment of sources and processes affecting sulfate and nitrate in surface water and groundwater of Luxembourg

Surface water and deep and shallow groundwater samples were taken from selected parts of the Grand-Duchy of Luxembourg to determine the isotopic composition of nitrate and sulfate, in order to identify sources and/or processes affecting these solutes. Deep groundwater had sulfate concentrations between 20 and 40 mg/L, d34Ssulfate values between -3.0 and -20.0‰, and d18Osulfate values between +1.5 and +5.0‰; nitrate was characterized by concentrations varying between

An overview of wireless networks in control and monitoring

This paper provides an overview of the current field in wireless networks for monitoring and control. Alternative wireless technologies are introduced, together with current typical industrial applications. The focus then shifts to wireless Ethernet and the specialised requirements for wireless networked control systems (WNCS) are discussed. This is followed by a brief look at some current WNCS research, including reduced communication control.

Co-design of Distributed Systems Using Skeleton and Autonomic Management Abstractions

We discuss how common problems arising with multi/many core distributed architectures can he effectively handled through co-design of parallel/distributed programming abstractions and of autonomic management of non-functional concerns. In particular, we demonstrate how restricted patterns (or skeletons) may be efficiently managed by rule-based autonomic managers. We discuss the basic principles underlying pattern+manager co-design, current implementations inspired by this approach and some result achieved with proof-or-concept, prototype.

Men, Women and an Integrated History of the Russian Revolutionary Movement

Since its emergence as a discipline in the 1960s, women’s history has had a profound effect on the study of the past. Scholarship on women’s experiences of and contributions to the Russian revolutionary movement has increased exponentially since the publication of a number of biographies of Aleksandra Kollontai in the 1970s and 1980s and a comprehensive picture has emerged of women’s involvement in all the major revolutionary parties, as leading figures as well as rank and file activists. Despite this wealth of historical discovery, remarkably little has found its way into so-called ‘general’ histories of the revolution. An integrated history, which is the ultimate aim of women’s history, has yet to be produced for the Russian revolutionary movement, even though recent prosopographical studies of revolutionary women have made clear the numerous ways in which men and women cooperated and interacted on a daily basis in the underground. This article explores the nature of and reasons for this failure, makes a case for why incorporating women’s experiences into the grand narrative of the Russian revolution is important and discusses how this might be achieved.

The WEU::A Europe of the Seven, 1954-1969

The history of the Western European Union after 1954–1955 is still a terra incognita. This article examines the function of the Western European Union in the Euro-Atlantic security architecture of the Cold War up to the 1960s. The paper studies the prime shifts of the tectonic plates forming the Western partial system of the bipolar Cold War system – and their systemic repercussions. The relationship between the Western umbrella organisation, NATO, and its European subsystem is analysed in four case studies: (1) the Arms Pool Negotiations of 1955; (2) Selwyn Lloyd's Grand Design of 1956–1957; (3) the wider Political European Union agenda of 1960–1962 and (4) the Western European Union nuclear force project of 1963.

Children of the revolution: parents, children and the revolutionary struggle in late imperial Russia

While there has been a considerable growth in scholarly interest in Russian child- hood and youth, the presence of children in the revolutionary movement has largely been overlooked. Studies of female revolutionaries have acknowledged that family concerns often had an impact on women’s party careers, but few have explored fully the relationship between mothers and their children. Similarly, “general” historical works on the Russian revolution have rarely engaged with questions about the family lives of the predominantly male party members. This article will assess how becoming a parent affected the careers of both male and female revolutionaries, as well as the ways in which familial concerns and the presence of children had an impact on the movement itself. It will highlight that children could have both positive and negative effects on the operations of the underground, at times disrupting activities, but at others proving to be useful decoys and helpers. Children’s attitudes to their parents’ revolutionary careers will also be examined, highlighting that while some children wished they had less politically active parents, others enthusiastically helped the movement. Though expanding the scholarly gaze on the Russian underground to take in the presence of children does not change the grand narrative of the revolution, it enriches our understanding considerably and offers a new insight into the daily struggles of the revolutionary movement.

Thermophysical properties of ionic liquids

Ionic liquids have received significant interest from research groups and industry for a range of novel applications. Many of these require a thorough knowledge of the thermophysical properties of the pure fluids and their mixtures. Despite this need, the necessary experimental data for many properties are scarce and often inconsistent between the various sources. However, by using accurate data, predictive physical models can be developed which are highly useful, and some would consider essential, if ionic liquids are to realise their full potential. This is particularly true if one can use them to design new ionic liquids which maximise key desired attributes. This paper will review some of the recent advances in our understanding, prediction and correlation of selected ionic liquid physical properties.

Inhuman and Degrading Punishment, Dignity, and the Limits of Retribution

The recent judgment of the Grand Chamber of the European Court of Human Rights (ECtHR) in Vinter and others v United Kingdom provides a much needed clarification of the parameters of the prohibition on inhuman and degrading punishment under Article 3 of the European Convention on Human Rights (ECHR) as it applies to whole life orders of imprisonment under mandatory life sentences – essentially, life imprisonment without parole. The Grand Chamber’s judgment refines Strasbourg doctrine on life imprisonment and the prospect of release and illuminates key principles concerning inhuman and degrading punishment under Article 3 of the ECHR. This article considers the judgment’s profound significance in relation to both human rights and penology.

The Kremlin's Scholar. A Memoir of Soviet Politics under Stalin and Khrushchev

The memoirs are dominated by two grand figures of Soviet history, Stalin and Khrushchev. The account of Stalin is riddled with ambiguities. There is an undoubted personal admiration for Stalin, his intellectual and political capacity (Stalin allegedly read 300 pages per day), his simplicity in daily life seen in "an old tunic, patched-up socks, almost constant isolation" (p. 190). At the same time, Shepilov acknowledged the paranoid aspects of Stalin's personality, especially towards the end of his life. Stalin's mechanisms of power are illustrated by Shepilov's account of work on a new book on political economy. Stalin personally chose key people for important tasks and controlled them at key junctures to ensure the desired outcome. In this light, Shepilov's claims that the Great Purges of the late 1930s could have been outside of Stalin's immediate control seem implausible, to say the least (p. 41).

All Stalin's deficiencies, however, pale in comparison with those of Khrushchev, the bête noire of Shepilov's memoirs. There is plenty of criticism of Khrushchev's policies, particularly in agriculture and foreign affairs. What comes across most pungently is, however, Shepilov's disdain of Khrushchev's personality and leadership style. In this respect, the book is unashamedly biased and remarkable for its omissions as much as for its revelations.
