Faulting in prospective CO2 storage sites in the UK Southern North Sea

Post-depositional folding of Triassic strata, formed largely by the development of salt domes and pillows in the underlying Zechstein Group, led to the formation of numerous large anticlinal structures at the level of the Triassic aged Bunter Sandstone Formation (BSF). These structural closures, some of which have formed effective traps to natural gas, have been mapped across the UK Southern North Sea (SNS), and are currently of interest as potential prospects for the storage of anthropogenic CO2

Inserting Migrants into the Global Social Protection Floor

The social protection floor (SPF) is a global initiative led by the International Labour Organization (ILO) to provide social security to vulnerable groups. The SPF neglects the rapidly growing population of international migrants and focusses principally on citizens from lower-income countries. The SPF requires a method to evaluate the social protection gap that exists between citizens and non-citizens in countries that receive migrants in order to improve protections for all. The SPF Advisory Group must collaborate more closely with transit and receiving countries, middle- and high-income countries, and regional organizations to reduce the gaps in social protection between citizens and non-citizens

Overpartition M2M2-rank differences, class number relations, and vector-valued mock Eisenstein series

We prove that the generating function of overpartition $M2$-rank differences is, up to coefficient signs, a component of the vector-valued mock Eisenstein series attached to a certain quadratic form. We use this to compute analogs of the class number relations for $M2$-rank differences. As applications we split the Kronecker-Hurwitz relation into its "even" and "odd" parts and calculate sums over Hurwitz class numbers of the form $\sum_{r \in \mathbb{Z}} H(n - 2r^2)$.Comment: 13 pages. v2 includes a notation and background section and changes some notatio

Evaluating lifelong learning networks

The focus of this short article is on the interim evaluation of Lifelong Learning Networks (LLNs) that the Centre for Higher Education Research and Information of The Open University was commissioned to undertake by the Higher Education Funding Council for England (HEFCE) during 2007 (HEFCE, 2008). It is not the intention to go into the detail of that evaluation, but instead to do two main things: to discuss the main challenges that the project team experienced in undertaking the evaluation, and to explore some of the challenges that LLNs are likely to experience as they reach the end of their HEFCE funding periods

The Effect of Print Angulation on the Accuracy and Precision of 3D-Printed Orthodontic Retainers

Purpose: The aims of this study were: 1) to compare the accuracy and precision of 3- dimensional (3D) printed retainers at various angulations, 2) to evaluate the effect of angulation on printing time and the amount of resin consumed. Methods: Using a stereolithography (SLA) 3D printer, a total of 60 clear retainers were printed at five angulations (n=12, each): 15, 30, 45, 60, and 90 degrees. Six retainers were printed each cycle at a random order for all print angulations as print 1 and print 2. Digital images of the original and printed retainers were superimposed. Discrepancies on eight landmarks were measured by two independent examiners. 0.25 mm was set as the clinically acceptable threshold to determine the accuracy of the retainers. Results: Deviations ranged from 0.074 mm to 0.225 mm from the reference retainer at the cusp tips and incisal edges at all angulations, falling within the threshold of clinical acceptance. Smooth surfaces ranged from 0.263 mm to 0.480 mm, falling beyond the level of clinical acceptance. Printing at 15 degrees was estimated to be the most time-efficient, while printing at 45 degrees was estimated to be the most cost-effective. Conclusions: 3D-printed retainers, using an SLA printer, were found to be accurate within 0.25 mm at all print angulations at the cusp tips and incisal edges when compared to the reference digital file. Smooth facial surfaces fell beyond of the level of clinical acceptability. Printing at 15 degrees was estimated to be the most time-efficient, while printing at 45 degrees was estimated to be the most cost-effective

State of fear: Britain's "compensation culture" reviewed

Assertions that Britain is (or is in danger of becoming) a 'blame and sue' society are nowadays so frequently repeated in the media and elsewhere that they have all but become received wisdom. Whether they express a dangerous reality or a passing moral panic deserves serious consideration because of their potential to influence legislative and judicial agendas. This article examines what is meant by the phrase 'compensation culture', evaluates the recent evidence concerning it, and attempts to assess whether the concerns expressed are justified.</p
