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

Este trabajo ha sido realizado en la Organización Europea para la Investigación Nuclear (CERN) y forma parte del proyecto de investigación Europeo para futuros aceleradores lineales (EUDET). En física de partículas existen diferentes categorías de detectores de partículas. El diseño presentado esta centrado en un tipo particular de detector de trayectoria de partículas denominado TPC (Time Projection Chamber) que proporciona una imagen en tres dimensiones de las partículas eléctricamente cargadas que atraviesan su volumen gaseoso. La tesis incluye un estudio de los objetivos para futuros detectores, resumiendo los parámetros que un sistema de adquisición de datos debe cumplir en esos casos. Además, estos requisitos son comparados con los actuales sistemas de lectura utilizados en diferentes detectores TPC. Se concluye que ninguno de los sistemas cumple las restrictivas condiciones. Algunos de los principales objetivos para futuros detectores TPC son un altísimo nivel de integración, incremento del número de canales, electrónica más rápida y muy baja potencia. El principal inconveniente del estado del arte de los sistemas anteriores es la utilización de varios circuitos integrados en la cadena de adquisición. Este hecho hace imposible alcanzar el altísimo nivel de integración requerido para futuros detectores. Además, un aumento del número de canales y frecuencia de muestreo haría incrementar hasta valores no permitidos la potencia utilizada. Y en consecuencia, incrementar la refrigeración necesaria (en caso de ser posible). Una de las novedades presentadas es la integración de toda la cadena de adquisición (filtros analógicos de entrada, conversor analógico-digital (ADC) y procesado de señal digital) en un único circuito integrado en tecnología de 130nm. Este chip es el primero que realiza esta altísima integración para detectores TPC. Por otro lado, se presenta un análisis detallado de los filtros de procesado de señal.

Yes / Background: Recruitment of patients with advanced cancer into studies is challenging. Objective: To evaluate recruitment methods in a study of pharmacist-led cancer pain medicines consultations and produce recommendations for future studies. Method: Two methods of recruitment were employed: 1) community-based (general practitioner computer search, identification by general practitioner, community pharmacist or district nurse and hospital outpatient list search), and 2) hospice-based (in and outpatient list search). Patients identified in method 1 were invited by post and in method 2 were invited face-to-face. Information was designed in collaboration with patients and carers. Results: 128 patients were identified (85 from the community and 43 from the hospice), 47 met the inclusion criteria. Twenty-three agreed to take part and 19 completed the study, 17 of whom were already under specialist palliative care. Recruitment rates were 7% for community-based methods and 40% for hospice. The recruitment methods differed in intensity of resource use. Recruitment via letter and a lack of engagement by healthcare professionals were found to be barriers. Facilitators included the researcher having personal involvement in recruitment. Conclusion: The overall recruitment rate was in line with other studies for this patient cohort. Attempts to identify and engage patients through community-based postal contact were less effective than where personal contact with patients was both possible and occurred. Methods were less successful at recruiting patients who were not already engaged with hospice services. / Programme Grants for Applied Research. Grant Number: RP-PG-0610-10114

No / 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.
