Performance of TenCate Paving Interlayers in Asphalt Concrete Pavements

As a continued effort of a previously completed project entitled “Performance of TenCate Mirafi PGM-G4 Interlayer-Reinforced Asphalt Pavements in Alaska,” this project evaluated two newly modified paving interlayers (TruPave and Mirapave) through overlay, dynamic modulus tests and low-temperature performance tests. A field survey was conducted to further evaluate the performance of three paving interlayers (G4, G50/50, and G100/100) applied to field sections constructed in May 2013 at Milepost 148–156 Richardson Highway in Alaska. Overlay test results indicate that asphalt concrete (AC) with paving interlayers (TruPave and Mirapave) shows lower reduction in peak load, suggesting better cracking resistance. The dynamic modulus measurement of AC with paving interlayers reveals more rational results from the IDT mode test than the AMPT method due to similar stress conditions in the paving interlayer. With paving interlayers, the temperature sensitivity and cracking potential of AC material were reduced according to the results from the IDT creep test. Field survey results confirm that all sections reinforced with paving interlayers (G4, G50/50, and G100/100) had better cracking resistance than the control section.TenCate Geosynthetics North Americ

Design of teaching materials informed by consideration of learning-impaired students

The general aim of this project is to fundamentally re-think the design of teaching materials in view of what is now known about cognitive deficits and about what Howard Gardner has termed ‘multiple intelligences’. The applicant has implemented this strategy in two distinct areas, the first involving the writing of an English language programme for Chinese speakers, the second involving the construction of specialized equipment for teaching elementary logic to blind students. The next phase (for which funding is sought) is to test the effectiveness of the logic device, because in theory – the one to be tested – materials the design of which is informed by the above rationale will provide a richer learning experience for non-impaired users

The LIFE2 final project report

Executive summary: The first phase of LIFE (Lifecycle Information For E-Literature) made a major contribution to understanding the long-term costs of digital preservation; an essential step in helping institutions plan for the future. The LIFE work models the digital lifecycle and calculates the costs of preserving digital information for future years. Organisations can apply this process in order to understand costs and plan effectively for the preservation of their digital collections The second phase of the LIFE Project, LIFE2, has refined the LIFE Model adding three new exemplar Case Studies to further build upon LIFE1. LIFE2 is an 18-month JISC-funded project between UCL (University College London) and The British Library (BL), supported by the LIBER Access and Preservation Divisions. LIFE2 began in March 2007, and completed in August 2008. The LIFE approach has been validated by a full independent economic review and has successfully produced an updated lifecycle costing model (LIFE Model v2) and digital preservation costing model (GPM v1.1). The LIFE Model has been tested with three further Case Studies including institutional repositories (SHERPA-LEAP), digital preservation services (SHERPA DP) and a comparison of analogue and digital collections (British Library Newspapers). These Case Studies were useful for scenario building and have fed back into both the LIFE Model and the LIFE Methodology. The experiences of implementing the Case Studies indicated that enhancements made to the LIFE Methodology, Model and associated tools have simplified the costing process. Mapping a specific lifecycle to the LIFE Model isn’t always a straightforward process. The revised and more detailed Model has reduced ambiguity. The costing templates, which were refined throughout the process of developing the Case Studies, ensure clear articulation of both working and cost figures, and facilitate comparative analysis between different lifecycles. The LIFE work has been successfully disseminated throughout the digital preservation and HE communities. Early adopters of the work include the Royal Danish Library, State Archives and the State and University Library, Denmark as well as the LIFE2 Project partners. Furthermore, interest in the LIFE work has not been limited to these sectors, with interest in LIFE expressed by local government, records offices, and private industry. LIFE has also provided input into the LC-JISC Blue Ribbon Task Force on the Economic Sustainability of Digital Preservation. Moving forward our ability to cost the digital preservation lifecycle will require further investment in costing tools and models. Developments in estimative models will be needed to support planning activities, both at a collection management level and at a later preservation planning level once a collection has been acquired. In order to support these developments a greater volume of raw cost data will be required to inform and test new cost models. This volume of data cannot be supported via the Case Study approach, and the LIFE team would suggest that a software tool would provide the volume of costing data necessary to provide a truly accurate predictive model

ALPS ePortfolio Project Report

The ALPS ePortfolio project was funded by the Yorkshire and Humber Strategic Health Authority (SHA) to involve students in investigating the use, benefits and requirements of ePorfolios in health and social care education. It was undertaken by the ALPS CETL (www.alps-cetl.ac.uk), which involved 5 universities and 16 health and social-care professions. Sixteen students were employed to work on the project, reviewing ePortfolio use and designing an ideal ePortfolio for health and social care education. The main project objectives were achieved; the project team identified benefits that could be achieved through ePortfolio use, wrote guidelines for the effective introduction of ePortfolios and agreed on the specification (a list of desired functionalities) for an ideal ePortfolio. In addition, the use of ePortfolios and reflective diaries increased within the student group and various approaches to championing ePortfolios (to both students and staff) were explored. The students enjoyed working as part of a project team alongside the academic staff; feeling that their work was valued and that they gained important skills and experiences from their involvement. The skills reported as being enhanced were in the common competency areas (teamworking, communication and interprofessional working) that the wider ALPS programme has been supporting. The students identified two key pieces of further work they thought was needed in this area: • To build the improved ePortfolio based on their specification. • To integrate ePortfolios more effectively into the courses and the professions Suggestions for integrating ePortfolios more effectively into their courses included: • linking it to other key university systems (email and submissions) to encourage daily use • ensuring that it provided a place where students could save and manage their own material as well as course reflections • better support and use by staff so that the ePortfolio acted as an interface between students and staff and • better links between HE and the professions' use of ePortfolios to ease the transition from education to the workplace Improved linking between the HE and professional use of ePortfolios is an area that the ALPS CETL is in a good position to investigate further, as the CETL has involved collaboration between the universities and 16 health and social care professions. Work in this area could be taken forward by the ALPS ePortfolio network (ALPS 2010) which was set up in Autumn 2010

All-ages Movement Project - Project Report

The All-ages Movement Project (AMP) is aiming to find and better understand youth-run cultural organizations focused on music in the United States. For four months, AMP has been exploring these organizations' social and political significance and the idea of enhancing their impact through a national network. AMP has designed a database that now houses the names of over 300 organizations that embody a combination of the following things: youth empowerment componentpopular music focusparticipatory structureproduce music related cultural products The names in AMP's database are turning into profiles and starting to tell a story about how this youthful and eclectic army of organizations is making change in the US in three areas of interest: meaningful cultural products, political impact, and alternative leadership opportunities.AMP looked at metrics in each of these areas to decipher if in fact this group of organizations is playing a role in creating the next generation of leaders through providing the environment and experiences that promote a culture of social change

Methods for the Evaluation of Quench Temperature Profiles and their Application for LHC Superconducting Short Dipole Magnets

This paper presents a study of the thermal effects on quench performance for several Large Hadron Collider single aperture short dipole models. The analysis is based on the temperature profile in a superconducting magnet evaluated after a quench. Peak temperatures and temperature gradients in the magnet coil are estimated for different thicknesses of insulation layer between the quench heaters and the coil and different powering and protection parameters. The results show clear correlation between the thermo-mechanical response of the magnet and quench performance. They also display that the optimisation of the position of quench heaters can reduce the decrease of training performance caused by the coexistence of a mechanical weak region and of a local temperature rise
