The assessment of the shear strength of soil deposits after the occurrence of large strains is an important issue for geotechnical engineers. One method for doing so, the steady state approach, is based on the assumption that the steady state undrained shear strength is a unique function of the in situ void ratio and effective stress. This method, which has been applied to liquefaction and flow failures, has been criticized because it may overestimate the in situ shear strength. The key to the steady state approach is accurate determination of the relationship between void ratio and effective stress at steady state. This is typically accomplished using conventional isotropically consolidated undrained (ICU) triaxial tests. The triaxial test was developed for measuring peak strengths, which typically occur at small strains, but steady state conditions typically occur at much larger strains. At large strain levels, the suitability of conventional triaxial testing procedures and error corrections is uncertain. The measured response at large strains may be inaccurate due to the influence of various testing errors. Furthermore, the true material response in the test specimen at large strains may not accurately represent in situ material behavior at large strains. This research effort consisted of an experimental and analytical study to examine the validity of steady state undrained shear strength determination using conventional ICU triaxial tests. The analytical study addressed triaxial testing errors and conventional corrections that are applied to test data and their influence on the measured steady state parameters. Finite element analyses were conducted to investigate the influence of variations in restraint at the end platens on stress distributions in the sample and measured stress-strain response. The finite element analyses incorporated axisymmetric interface elements to model the friction characteristics between the end platens and the specimen ends. The experimental study focused on several sands that are susceptible to liquefaction. An interface direct shear test program was conducted in order to evaluate various schemes for reducing end platen friction. ICU triaxial tests were conducted on each material using both conventional and lubricated end platens. / Ph. D.

Care homes play a major role in supporting people with dementia at the end of their lives. Seeking to understand the views of staff on the care they provide, Nicola Wheeler and Jan R Oyebode held focus groups with a range of staff in nine care homes in the West Midlands. Here they discuss their findings and implications for practice.

Yes / To evaluate a 24/7, nurse led telephone and video-consultation support service for patients thought to be in the last year of life in Bradford, Airedale, Wharfedale and Craven. Method: Activity and other data recorded at the time of calls were analysed. Interviews with 13 participants captured patients and carers perspectives. Results: Between April 1st 2014 and March 31st 2015, 4648 patients were registered on the Gold Line. 42% had a non-cancer diagnosis and 46% were not known to specialist palliative care services. The median time on the caseload was 49 days (range 1-504 days). 4533 telephone calls and 573 video consultations were received from 1813 individuals. 39% of the 5106 calls were resolved by Gold Line team without referral to other services. 69% of calls were made outside normal working hours. Interviews with patients and carers reported experiences of support and reassurance and the importance of practical advice. Conclusion: A nurse led, 24/7 telephone and video consultation service can provide valuable support for patients identified to be in the last year of life and their cares. The line enabled them to feel supported and remain in their place of residence, reducing avoidable hospital admissions and use of other services. Providing this service may encourage health care professionals to identify patients approaching the last year of life, widening support offered to this group of patients beyond those known to specialist palliative care services. / Health Foundation adn Shared Purpose

No / People with dementia need increasingly specialised support as they approach the end of life, and so too do their families and the professionals working with them. This book describes not only what can be done to ensure maximum quality of life for those in the final stages of the illness, but also how best to support those involved in caring for them. Emphasising the importance of being attuned to the experiences and needs of the person with dementia, the authors explain why and how they should be included in decisions relating to their end of life care. Practical strategies for ensuring physical and emotional wellbeing are provided, drawing on useful examples from practice and providing solutions to potential challenges that carers and family members will face. Dilemmas surrounding end of life care are explored in detail, including the moral dilemma of medical intervention, and the authors suggest ways of supporting family members through the process in terms of providing information, helping them adjust to change and loss, and involving them in their relative's care, and at how care staff can be supported through appropriate education and training, team building and information-giving.

Yes / Approximately 700 000 people in the UK have dementia, rising to 1.2 million by 2050; one-third of people aged over 65 will die with dementia. Good end-of-life care is often neglected, and detailed UK-based research on symptom burden and needs is lacking. Our project examines these issues from multiple perspectives using a rigorous and innovative design, collecting data which will inform the development of pragmatic interventions to improve care. Methods and analysis: To define in detail symptom burden, service provision and factors affecting care pathways we shall use mixed methods: prospective cohort studies of people with advanced dementia and their carers; workshops and interactive interviews with health professionals and carers, and a workshop with people with early stage dementia. Interim analyses of cohort data will inform new scenarios for workshops and interviews. Final analysis will include cohort demographics, the symptom burden and health service use over the follow-up period. We shall explore the level and nature of unmet needs, describing how comfort and quality of life change over time and differences between those living in care homes and those remaining in their own homes. Data from workshops and interviews will be analysed for thematic content assisted by textual grouping software. Findings will inform the development of a complex intervention in the next phase of the research programme. Ethics and dissemination: Ethical approval was granted by National Health Service ethical committees for studies involving people with dementia and carers (REC refs. 12/EE/0003; 12/LO/0346), and by university ethics committee for work with healthcare professionals (REC ref. 3578/001). We shall present our findings at conferences, and in peer-reviewed journals, prepare detailed reports for organisations involved with end-of-life care and dementia, publicising results on the Marie Curie website. A summary of the research will be provided to participants if requested. / Marie Curie Cancer Care

An experimental investigation was conducted to study the inelastic rotation capability of flush end-plate moment connections. Seven specimens representing two-bolt and four-bolt flush end-plate configurations were tested under cyclic loading. "Quasi-static" or "slow-cyclic" loading histories suggested by SAC and the Applied Technology Council were used to load the specimens. Experimental results for maximum moment resisted by the connections were compared with analytical predictions. Moment strengths of the connections were calculated using yield-line theory to predict end-plate yielding and maximum bolt force calculations including prying action. Experimental results were also compared to previous research with regards to strength and stiffness. The inelastic rotation of connections was calculated and conclusions were drawn on the compliance of these connections with current AISC specifications. / Master of Science
