    Abstract We provide evidence of a positive effect of major infrastructure development on international trade, using the opening of the fixed link between Denmark and Sweden in 2000 (The Oresund Bridge) as a quasi-natural experiment. Our Synthetic Control Method (SCM) constructs a counterfactual Danish-Swedish trade relationship, which represents bilateral trade in the absence of the bridge. Evaluating actual trade against its synthetic counterpart for the period 2001-2008 shows that Danish-Swedish trade was 24.6% larger than it would have been in the absence of the bridge using our preferred specification. The result is robust to standard sensitivity checks. We supplement our analysis with a standard Difference-in-differences (DiD) estimator, which uses fixed effects. The DiD estimator yields a slightly larger trade effect of 26.7%, and is robust to a number of sensitivity analyses, including estimation at the product level. Both our SCM and DiD point to the trade-boosting effects being gradual.

    Abstract With the rapid development of nanotechnology, there is urgent need of characterizing techniques; especially determining the particle size distribution directly from solution. Dynamic light scattering is often used but presence of a small number of aggregates can greatly influence the size distribution. Electrospray scanning mobility particle sizer (ES-SMPS) is rapidly emerging as an alternative method in colloidal science. However, a major limitation is the use of silica-coated capillaries, which are negatively charged at pH > 3, and therefore making its use difficult for positively charged nanoparticles. In this work, we have developed the polyether ether ketone (PEEK) capillary for ES-SMPS, which removes this limitation because it carries no charge. We have shown that the new capillary not only produced equally good particle size distributions for negatively charged particles (SiO

    Abstract A novel method for measuring particle multiplicity correlations is presented. The method takes reduced acceptance and detection efficiency into account, in a purely statistical manner. The method does therefore not require any information from simulations - only knowledge of the detectors capability. The method provides the ability to measure forward-backward particle multiplicity correlations with high accuracy and negligible bias. The validity of the method is provided through numerous simulations. The correlation values calculated from carefully selected detection acceptances and efficiencies are compared to the correlation values at the event-generator level. Further validity to the method is given by incorporating different event generators into the simulations. Although the emphasis is on fwd-bwd correlations, the method can be extended to other multiplicity correlation measurements.

    Abstract Why are trade agreements regional? I address this question in a model of oligopoly featuring product variety. Tariffs have the effect of manipulating a country's terms of trade and shifting profits towards the domestic market at the expense of foreign trade partners. Countries endogenously form into regional trade agreements or global free trade in a framework where any agreement must be sustained by repeated interaction. A crucial parameter determining the degree of regionalism is product variety. I demonstrate that for a given trade cost and discount factor, increases in product variety leads to greater scope for global free trade relative to regional trade agreements.

    Abstract Understanding the nature of specific interaction of ions with the charged silica nanoparticles is vital not only to produce gels for applications such as grouting but also for determining their long term stability. Interaction of silica nanoparticles in single salt solutions has been thoroughly investigated but in mixed salt solutions is rarely investigated. In this work we have investigated the gelling of silica nanoparticles in the mixtures of monovalent ions as well as in the mixtures of divalent and monovalent ions. To gain an understanding of the interaction of ions with the charged silica surface at molecular level we have performed molecular dynamics (MD) simulations. Our overall goal was to find out if in salt mixtures ions silica interactions follow the Hofmeister series or not and how ion specific interactions may change when chaotropic ions are successively replaced by kosmotropic or vice versa. The gelling results show that generally monvalent ions in salt mixtures follow the Hofmeister series, e.g., the gel times in the mixtures of lithium and sodium chlorides are much longer than in the mixtures of lithium and potassium chlorides. On the other hand, gel times in the salt mixtures containing divalent ions do not follow the expected Hofmeister series e.g. mixtures of magnesium and sodium chlorides show shorter gel times than that of calcium and sodium chlorides. However, pH dependent gelling revealed that at pH values less than 9 gelling in these mixtures follow the normal Hofmeister series i.e., longer gelling time in magnesium and sodium chlorides than in calcium and sodium chlorides. This reversal of Hofmeister series for divalent and monovalent salt mixtures at pH > 9 and normal Hofmeister series at pH < 9 is reported for the first time in literature. Such a revesal at pH> 9 is explained due to enhanced surface charge, ordring of surface water layer which leads to enhanced ion specificity of strongly hydrated ions such as Mg²⁺. Moreover, in mixtures having the same divalent salt but different monovalent salts such as magnesium chlorides mixtures with lithium, sodium and potassium chlorides a normal Hofmeister series prevails. MD simulations results revealed that Mg²⁺ ions retain their strong hydration shell while interacting with the oppositely charged silica surface which means that the shorter gelling times obtained in magnesium salts mixtures are not due to inner sphere complexation of magnesium with the silica surface. Instead magnesium interacts with the silica surface through its hydrating water molecules.

    Abstract Objective: To understand perspectives on and acceptability of prehabilitation among patients undergoing complex abdominal cancer surgery (cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy).
    Methods: Seventy-nine patients admitted to a Danish colorectal or ovarian cancer centre participated in qualitative semi-structured interviews and/or registered their prehabilitation activities based on preoperative recommendations presented in a leaflet. Malterud's principles of systematic text condensation were used to analyse the interview data, and descriptive statistics were used to describe the activity registrations.
    Results: Five domains clarify central aspects of the patients' perspectives on and acceptability of prehabilitation: the preoperative period, attitudes towards prehabilitation, the actual prehabilitation performed, motivation to take action and the need for support.
    Conclusion: Patients undergoing major abdominal cancer surgery are interested in and positive towards prehabilitation, but it has to be on their terms. The patients need support and supervision, but it has to be provided in a setting and in a way that are in line with the patient's preferences, resources and values. Thus, patient involvement is necessary to create prehabilitation programmes that are feasible and fit into patients' everyday lives.

    Abstract At present there is a pressing need to find an environmentally friendly grouting material for the construction of tunnels. Silica nanoparticles hold great potential of replacing the organic molecule based grouting materials currently used for this purpose. Chemically, silica nanoparticles are similar to natural silicates which are essential components of rocks and soil. Moreover, suspensions of silica nanoparticles of different sizes and desired reactivity are commercially available. However, the use of silica nanoparticles as grouting material is at an early stage of its technological development. There are some critical parameters such as long term stability and functionality of grouted silica that need to be investigated in detail before silica nanoparticles can be considered as a reliable grouting material. In this review article we present the state of the art regarding the chemical properties of silica nanoparticles commercially available, as well as experience gained from the use of silica as grouting material. We give a detailed description of the mechanisms underlying the gelling of silica by different salt solutions such as NaCl and KCl and how factors such as particle size, pH, and temperature affect the gelling and gel strength development. Our focus in this review is on linking the chemical properties of silica nanoparticles to the mechanical properties to better understand their functionality and stability as grouting material. Along the way we point out areas which need further research.

    Abstract Background: Patients' perspectives on standardised, multimodal prehabilitation programmes showed barriers to adherence. Further investigation of patients' ability to prepare is needed.
    Aim: To investigate what patients with cancer who were due to undergo major abdominal surgery actually were able to do when provided with preoperative, home-based, multimodal recommendations presented in a leaflet.
    Methods: Patients from the colorectal- or ovarian cancer centre, who were scheduled for major abdominal surgery, received a leaflet with preoperative recommendations. On a daily basis, the patients filled in what they had completed in relation to these recommendations, so that adherence could be investigated. Additionally, face-to-face interviews were conducted to evaluate patients' experiences of using the leaflet. Malterud's principles of systematic text condensation were used to analyse the interviews. A convergent design was used to merge the quantitative and qualitative data into a combined interpretation presented in the discussion.
    Results: A total of 53 patients returned a completed leaflet, and five patients were interviewed. In the combined interpretation, patients' ability to prepare was presented through four major domains. The domains were adherence and the importance of support, manageable actions leading to change, preparation in a broader perspective and impediments to preparation and to symptom relief.
    Conclusions: Patients prepared themselves in various ways, which were not limited to recommendations inspired by multimodal prehabilitation. Patients from the ovarian cancer centre increased their weekly exercise during the preoperative period, which indicates that the leaflet not only functioned as a data collection tool, but also motivated and supported the patients in prehabilitation-related actions. Patients' perspectives on prehabilitation need to be taken into account, when aiming to enhance patient-centredness and adherence.
