    Physics of Neutron Star Crusts

    Get PDF
    The physics of neutron star crusts is vast, involving many different research fields, from nuclear and condensed matter physics to general relativity. This review summarizes the progress, which has been achieved over the last few years, in modeling neutron star crusts, both at the microscopic and macroscopic levels. The confrontation of these theoretical models with observations is also briefly discussed.Comment: 182 pages, published version available at <http://www.livingreviews.org/lrr-2008-10

    The radicalization of democracy: conflict, social movements and terrorism

    Get PDF
    The idea of democracy is being championed across the world, with some fifty new countries embracing this type of political system between 1974 and 2011 (Freedom House, 2016). Simultaneously, however, dissatisfaction has grown due to the perceived incapacity of democracy to deal with collective problems, hence the necessity to reconfigure it and redraw some of its principles. This paper links the analysis of the recent evolution of democratic systems with the trajectory of socio-political conflicts and the changing features of contemporary terrorism. It examines, therefore, two intertwined phenomena, namely the radicalization of democracy and the radicalization of the other. It concludes by stressing that encouraging dissent and heeding contentious claims made by social movements may be one way of mitigating both types of radicalization. Embedded in the tradition of critical criminology, this paper attempts to demonstrate that only by outflanking conventional categories of analysis can the criminological community aspire to grasp such thorny contemporary phenomena

    Not Quite Right: Representations of Eastern Europeans in ECJ Discourse

    Get PDF
    Although the increasing responsiveness of the Court of Justice of the European Union (the ‘ECJ’) jurisprudence to western Member States’ concerns regarding Central and Eastern European (‘CEE’) nationals’ mobility has garnered academic attention, ECJ discourse has not been scrutinised for how it approaches the CEE region or CEE movers. Applying postcolonial theory, this article seeks to fill this gap and to explore whether there are any indications that ECJ discourse is in line with the historical western-centric inferiorisation of the CEE region. A critical discourse analysis of a set of ECJ judgments and corresponding Advocate General opinions pertaining to CEE nationals illustrates not only how the ECJ adopts numerous discursive strategies to maintain its authority, but also how it tends to prioritise values of the western Member States, while overlooking interests of CEE movers. Its one-sided approach is further reinforced by referring to irrelevant facts and negative assumptions to create an image of CEE nationals as socially and economically inferior to westerners, as not belonging to the proper EU polity and as not quite deserving of EU law’s protections. By silencing CEE nationals’ voices, while disregarding the background of east/west socio-economic and political power differentials and precariousness experienced by many CEE workers in the west, such racialising discourse normalises ethnicity- and class-based stereotypes. These findings also help to contextualise both EU and western policies targeting CEE movers and evidence of their unequal outcomes in the west, and are in line with today’s nuanced expressions of racisms. By illustrating the ECJ’s role in addressing values pertinent to mobile CEE individuals, this study facilitates a fuller appreciation of the ECJ’s power in shaping and reflecting western-centric EU identity and policies. Engaging with such issues will not only allow us to better appreciate—and question—the ECJ’s legitimacy, but might also facilitate a better understanding of power dynamics within the EU. This study also makes significant theoretical and methodological contributions. It expands (and complicates) the application of postcolonial theory to contemporary intra-EU processes, while illustrating the usefulness of applying critical discourse analysis to exploring differentiation, exclusion, subordination and power within legal language

    Coenzyme A:to make it or uptake it?

    No full text
    The consensus has been that intracellular coenzyme A (CoA) is obtained exclusively by de novo biosynthesis via a universal, conserved five-step pathway in the cell cytosol. However, old and new evidence suggest that cells (and some microorganisms) have several strategies to obtain CoA, with 4'-phosphopantetheine (P-PantSH; the fourth intermediate in the canonical CoA biosynthetic pathway) serving as a 'nexus' metabolite

    In vitro reconstruction of tetronate RK-682 biosynthesis

    No full text
    The protein phosphatase inhibitor RK-682 is one of a number of potentially valuable tetronate polyketide natural products. Understanding how the tetronate ring is formed has been frustrated by the inaccessibility of the putative substrates. We report the heterologous expression of rk genes in Saccharopolyspora erythraea and reconstitution of the RK-682 pathway using recombinant enzymes, and we show that RkD is the enzyme required for RK-682 formation from acyl carrier protein–bound substrates
