No full textUranium-mediated oxidative addition and reductive elimination
No full textOxidative addition, and its reverse reaction reductive elimination, constitute two key reactions that underpin organometallic chemistry and catalysis. Although these reactions have been known for decades in main group and transition metal systems, they are exceptionally rare or unknown for the f-block. However, in recent years much progress has been made. In this Perspective article, advances in uranium-mediated oxidative addition/reductive elimination, since the point that this research area was initiated in the early-1980s, are summarised. We principally divide the Perspective into two parts of oxidative addition and reductive elimination, along with a separate section concerning reactions where there is no change of uranium oxidation state in reactant and product but the reaction has the formal appearance of a ‘concerted’ reductive elimination/oxidative addition from the perspective of the net result. This body of work highlights that whilst uranium is capable of performing reactions that to some extent conform to traditional reactivity types, novel reactivity that has no counterpart anywhere else can be performed, thus adding to the rich palate of redox chemistry that uranium can mediate
Global modeling of the nitrate radical (NO3) for present and pre-industrial scenarios
No full textIncreasing the complexity of the chemistry scheme in the global chemistry transport model STOCHEM to STOCHEM-CRI (Utembe et al., 2010) leads to an increase in NOx as well as ozone resulting in higher NO3 production over forested regions and regions impacted by anthropogenic emission. Peak NO3 is located over the continents near NOx emission sources. NO3 is formed in the main by the reaction of NO2 with O-3, and the significant losses of NO3 are due to the photolysis and the reactions with NO and VOCs. Isoprene is an important biogenic VOC, and the possibility of HOx recycling via isoprene chemistry and other mechanisms such as the reaction of RO2 with HO2 has been investigated previously (Archibald et al., 2010a). The importance of including HOx recycling processes on the global budget of NO3 for present and pre-industrial scenarios has been studied using STOCHEM-CRI, and the results are compared. The large increase (up to 60\% for present and up to 80\% for pre-industrial) in NO3 is driven by the reduced lifetime of emitted VOCs because of the increase in the HOx concentration. The maximum concentration changes (up to 15 ppt) for NO3 from pre-industrial to present day are found at the surface between 30 degrees N and 60 degrees N because of the increase in NOx concentrations in the present day integrations.

Utilizing community and voluntary sector partnerships to survey and compare the health outcomes of hard-to- reach groups to the wider community-the EURO- URHIS 2 Hard-to-Reach Project
No full textBACKGROUND: This article describes the Hard-to-Reach (HtR) Project that was developed to capture health and lifestyle data from groups who are HtR by postal surveys within the larger EURO-URHIS 2 project. By collaborating with partner organizations, data were collected using standard survey tools, allowing for comparison with the wider population. METHODS: Following a scoping exercise to determine which groups were HtR in Greater Manchester, black and minority ethnic (BME) groups and students were selected. BME groups were surveyed through partnership with Community and Voluntary Sector Organizations (CVSOs). Language barriers were addressed through the recruitment of volunteer interpreters. Students were surveyed by accessing university premises. RESULTS: Fifteen survey visits took place at nine CVSOs and five visits to University facilities. In total, 144 eligible surveys were collected. There were significant differences for both HtR groups, compared with Greater Manchester and the EURO-URHIS 2 mean. Both HtR groups had worse outcomes than both Greater Manchester and EURO-URHIS 2 for psychological problems. In addition, students had worse outcomes for passive smoking, binge drinking, use of cannabis, lack of access to green spaces, less sense of belonging and social cohesion and damp or mildewed homes, and better outcomes for self-perceived health and overweight and obesity. BME had in addition worse outcomes than both Greater Manchester and EURO-URHIS 2 for long-standing restrictive illness. CONCLUSION: Despite the limitations of this study, the development of this methodology allowed for the collection of comparable data, showing up statistically significant differences between the HtR populations and the wider population which merits further investigation
The Computational Fluid Dynamics Rupture Challenge 2013—Phase II: variability of hemodynamic simulations in two intracranial aneurysms
No full textWith the increased availability of computational resources, the past decade has seen a rise in the use of computational fluid dynamics (CFD) for medical applications. There has been an increase in the application of CFD to attempt to predict the rupture of intracranial aneurysms, however, while many hemodynamic parameters can be obtained from these computations, to date, no consistent methodology for the prediction of the rupture has been identified. One particular challenge to CFD is that many factors contribute to its accuracy; the mesh resolution and spatial/temporal discretization can alone contribute to a variation in accuracy. This failure to identify the importance of these factors and identify a methodology for the prediction of ruptures has limited the acceptance of CFD among physicians for rupture prediction. The International CFD Rupture Challenge 2013 seeks to comment on the sensitivity of these various CFD assumptions to predict the rupture by undertaking a comparison of the rupture and blood-flow predictions from a wide range of independent participants utilizing a range of CFD approaches. Twenty-six groups from 15 countries took part in the challenge. Participants were provided with surface models of two intracranial aneurysms and asked to carry out the corresponding hemodynamics simulations, free to choose their own mesh, solver, and temporal discretization. They were requested to submit velocity and pressure predictions along the centerline and on specified planes. The first phase of the challenge, described in a separate paper, was aimed at predicting which of the two aneurysms had previously ruptured and where the rupture site was located. The second phase, described in this paper, aims to assess the variability of the solutions and the sensitivity to the modeling assumptions. Participants were free to choose boundary conditions in the first phase, whereas they were prescribed in the second phase but all other CFD modeling parameters were not prescribed. In order to compare the computational results of one representative group with experimental results, steady-flow measurements using particle image velocimetry (PIV) were carried out in a silicone model of one of the provided aneurysms. Approximately 80% of the participating groups generated similar results. Both velocity and pressure computations were in good agreement with each other for cycle-averaged and peak-systolic predictions. Most apparent “outliers” (results that stand out of the collective) were observed to have underestimated velocity levels compared to the majority of solutions, but nevertheless identified comparable flow structures. In only two cases, the results deviate by over 35% from the mean solution of all the participants. Results of steady CFD simulations of the representative group and PIV experiments were in good agreement. The study demonstrated that while a range of numerical schemes, mesh resolution, and solvers was used, similar flow predictions were observed in the majority of cases. To further validate the computational results, it is suggested that time-dependent measurements should be conducted in the future. However, it is recognized that this study does not include the biological aspects of the aneurysm, which needs to be considered to be able to more precisely identify the specific rupture risk of an intracranial aneurysm
The Profile of Gender Equality Issue Attention in Western Europe
No full textThis article investigates the factors that drive governments to pay attention to gender equality issues and place them upon executive agendas. In line with studies of the dynamics of issue attention, which demonstrate the importance of investigating variability in the attention policy makers give to issue demands across policy domains, this article argues that policy issues related to gender equality are multidimensional and patterns in executive attention vary across the different types of gender issues. Multidimensionality of gender equality issues reflects different dynamics in agenda‐setting as different issues invoke contrasting constellations of political representation, institutional friction and veto points. To investigate this variation, this article proposes a twofold distinction between class‐based and status‐based gender equality issues and assesses the validity of three sets of explanations for when gender issues succeed in reaching executive agendas: women in politics, party ideology and economic performance. Drawing on governmental attention datasets from the Comparative Agendas Project, a systematic comparative quantitative analysis of the determinants of gender equality issue attention in five Western European countries is conducted. The main findings confirm that the mechanisms through which different types of gender equality issues gain executive attention differ according to the kind of the gender equality demand. Costly class‐based gender equality issues are more likely to receive executive attention when the economy is performing well, when there is a strong presence of Social Democrats and when there is a high proportion of female MPs. In contrast, economic performance, party politics and women's parliamentary presence do not seem to exert any impact on status‐based issues. Instead, critical actors in the government seem to be the strongest driver for attention over this second type of gender equality issue. This study contributes a gendered dimension to the policy agendas scholarship, adding theoretical and empirical depth to the understanding of how non‐core issues secure their place on full governmental agendas. By focusing on how to secure governmental attention for gender equality issues, the article makes a major contribution to understanding the initial genesis of gender equality policies
