    Delivering Sustainable Transport for the Grangegorman Urban Quarter

    Get PDF
    This paper looks at the challenges and opportunities posed in delivering sustainable transport for an education, health and mixed use campus development at Grangegorman, Dublin. It looks the transport strategy for the largely pedestrian development, which places emphasis on sustainable modes. The paper looks at how existing positive modal split of the Dublin Institute of Technology can be maintained and improved in the relocation of the Institute to a consolidated campus and how other users can be encouraged to adopt sustainable modes of transport. Work conducted to date on active mobility management for users of the Grangegorman campus is described

    Collateral and Debt Maturity Choice. A Signaling Model

    Get PDF
    This paper derives optimal loan policies under asymmetric information where banks offer loan contracts of long and short duration, backed or unbacked with collateral. The main novelty of the paper is that it analyzes a setting in which high quality firms use collateral as a complementary device along with debt maturity to signal their superiority. The least-cost signaling equilibrium depends on the relative costs of the signaling devices, the difference in firm quality and the proportion of good firms in the market. Model simulations suggest a non-monotonic relationship between firm quality and debt maturity, in which high quality firms have both long-term secured debt and short-term secured or non-secured debt.

    Fluorescent nanodiamonds: past, present, and future

    Get PDF
    Multi-color fluorescent nanodiamonds (FNDs) containing a variety of color centers are promising fluorescent markers for biomedical applications. Compared to colloidal quantum dots and organic dyes, FNDs have the advantage of lower toxicity, exceptional chemical stability, and better photostability. They can be surface functionalized by techniques similar to those used for other nanoparticles. They exhibit a variety of emission wavelengths from visible to near infrared, with narrow or broad bandwidths depending on their color centers. In addition, some color centers can detect changes in magnetic fields, electric fields, and temperature. In this article review, we will discuss the current trends in FND’s development, including comparison to the early development of quantum dots. We will also highlight some of the latest advances in fabrication, as well as demonstrations of their use in bioimaging and biosensing

    Lanthanide ions doped in vanadium oxide for sensitive optical glucose detection

    Blood glucose monitoring is essential to avoid the unwanted consequences of glucose level fluctuations. Optical monitors are of special interest because they can be non-invasive. Among optical glucose sensors, fluorescent upconversion nanoparticles (UCNPs) have the advantage of good photostability, low toxicity, and exceptional autofluorescence suppression. However, to sense glucose, UCNPs normally need surface functionalization, and this can be easily affected by other factors in biological systems, and may also affect their ability for real-time sensing of both increasing and decreasing glucose levels. Here, we report YVO4 : Yb3+, Er3+@Nd3+core/shell UCNPs with Nd and Yb shell and GdVO4 : Yb3+, Er3+@Nd3+ core/shell UCNPs with Nd and Yb shell that show sensitive, reversible, and selective optical glucose detection without the need for any surface functionalization or modifications

    Beyond the COVID-19 Pandemic: Tips for Players and Athletes COVID-RECOVER

    First paragraph: The aim of this guidance is to provide a framework for athletes to cope, thrive and engage in personal growth during the current pandemic. The COVID-19 pandemic has likely led to wide-scale disruption of your sporting trajectories for 2020. This has included the cancellation or postponement of sporting events, limits to group training due to social distancing, restrictions on use of sporting facilities and loss of face-to-face access to coaches and support personnel. In the context of a threat to public health, arguably sports competition sinks into lesser importance, but for athletes like you, for whom sport is a fulltime job or major life goal, or for those who identify sports competition as a key part of their identity, it is important to share recommendations based on evidence and theory on how to support athletes and players through this time. The unprecedented situation means that evidence from similar or related contexts and relevant theories needs to be used to extrapolate to COVID-19 and all its challenges. Each of the guidelines below should be viewed like a menu to choose from and try, test and review, and be seen as a road to discovery instead of passive prescription of activities. Our team of practitioners and researchers have collated the knowledge below based on four premises: 1. Psychological Strengths: As a performer on the sporting stage, you have, in all likelihood, developed many skills and habits to support your on-field performance. Pre-performance routines for penalty taking, for example, may include relaxation and focusing components which aid emotional regulation. This can be also applied to help you cope in world outside of sport (i.e. outside the bubble). Awareness of your repertoire of psychological skills and the ability to use them across different contexts is highly important. 2. Resilience: The capacity to mobilise resources both in advance and after a major challenge, is developed through our sporting challenges. In the face of a trauma, it is likely that resilience is the default rather than the exception. As an athlete, you have the ability to respond in an optimistic way to major stressors and engage in post-traumatic growth. Further, you have successful experiences from memory to call upon on which By doing this, you build a firm foundation on which to build your beliefs that you have sufficient resources to cope with COVID-19. 3. Individual Responses: It is important to acknowledge that athletes in different sports and at different levels of competition have developed diverse sets of abilities and competencies. Dual-career athletes (e.g. student-athletes) may have invested much of their effort in their sport despite study or work commitments, and injured athletes may be over-identifying with their sport as a predictable response to injury, in both cases making these athletes very vulnerable to major stressors. 4. Perception of Control: Loss of control is a major source of anxiety in a pandemic (see Mansell, 2020). Developing autonomy and a sense of control is a key part to feeling safe and secure. With COVID-19, the new habits that could help protect you such as physical isolation, hand hygiene, and avoiding touching your face can help you gain control in an uncertain world. And finding new ways to exercise, to work and to interact can open up a world of exciting possibilities. Athletes have shown an ability to develop positive habits and maintain self-control, skills transferable to meeting the present challenging circumstances
