Dipole and Quadrupole electroexcitations of the isovector T=1 particle-hole states in C-12

Electroexcitations of the dominantly T=1 particle-hole states of C-12 are studied in the framework of the harmonic oscillator shell model. All possible T=1 single-particle-hole states of all allowed angular momenta are considered in a basis including single-particle states up to the 1f-2p shell. The Hamiltonian is diagnoalized in this space in the presence of the modified surface delta interaction. Correlation in the ground state wave functions by mixing more than one configuration is considered and shows a major contribution that leads to enhance the calculations of the form factors. A comparison with the experiment shows that this model is able to fit the location of states and a simple scaling of the results give a good fit to the experimental form factors.Comment: 5 pages, 4 figures, 5 tables, Late

Chemical reaction and heat transfer on boundary layer Maxwell Ferro-fluid flow under magnetic dipole with Soret and suction effects

AbstractIn this article, the influence of chemical reaction and heat transfer analysis of Maxwell saturated Ferro-fluid flow over a stretching sheet under the influence of magnetic dipole with Soret and suction effects are investigated. The sheet is assumed to be permeable in a semi-infinite domain. Firstly, partial differential equations of mass, momentum and concentration for the governing flow problem are modelled and converted into a system of differential equations by utilizing similarity approach. Then the solution of resulting non-linear differential equations is solved by efficient Runge-Kutta technique based on shooting algorithm with the help of MATLAB. Effect of all appropriate parameters like ferromagnetic interaction parameter, chemical reaction parameter, Maxwell parameter, Soret number, suction parameter, Maxwell parameter, Schmidt number, and suction parameter on velocity, temperature and concentration field are confirmed through graphs and table. From the present conclusions, it is examined that by increasing the Maxwell parameter there is a decrease in the fluid velocity and boundary layer thickness. On the other hand, the uprising behaviour is prominent for both temperature and concentration profiles. Also predicted that there is an enhancement in skin friction coefficient and rate of heat transfer by enlarging suction parameter, but opposite trend is noted for Sherwood number. Also noted that the values of Prandtl are taken ranges from 0.72 to 10. The Nusselt number increases from 1.09 to 4.80

Key priority areas for patient safety improvement strategy in Libya: a protocol for a modified Delphi study

Introduction Patient safety is a global public health problem. Estimates and size of the problem of patient safety in low-income and developing countries are scarce. A systems approach is needed for ensuring that patients are protected from harm while receiving care. The primary objective of this study will be to use a consensus-based approach to identify the key priority areas for patient safety improvement in Libya as a developing country. Design A modified Delphi study. Methods and analysis A three-phase modified Delphi study will be conducted using an anonymous web-based questionnaires. 15 international experts in the field of patient safety will be recruited to prioritise areas of patient safety that are vital to developing countries such as Libya. The participants will be given the opportunity to rank a list of elements on five criteria. The participants will also be asked to list five barriers that they believe hinder the implementation of patient safety systems. Descriptive statistics will be used to evaluate consensus agreement, including percentage agreement and coefficient of variation. Kendall’s coefficient of concordance will be used to evaluate consensus across all participants. Ethics and dissemination Ethical approval has been granted from Imperial College Research Ethics Committee (ICREC: 16IC3598). The findings of the study will be published in a PhD thesis. A manuscript will also be prepared for publication in a high-impact peer-reviewed journal describing the Delphi process and the findings of the study

The justice system is failing victims and survivors of sexual violence

Tammi Walker, Alison Foster, Rabiya Majeed-Ariss and Miranda Horvath on a role for psychologists in improving processes and protection around rape cases. The justice system in England and Wales continues to fail survivors of sexual violence. Official figures from the Crown Prosecution Service and Police highlight the ongoing problem of attrition of rape cases from the criminal justice system. Here, we outline the limitations of the endless cycle of reviews in response to the poor treatment of survivors. We argue that solutions which could lead to significant improvements for survivors of sexual violence are possible

Patients' views on improving sickle cell disease management in primary care: focus group discussion.

OBJECTIVES: To assess sickle cell disease (SCD) patient and carer perspectives on the primary care services related to SCD that they receive from their general practitioner (GP). DESIGN: A focus group discussion was used to elicit the views of patients about the quality of care they receive from their primary health-care providers and what they thought was the role of primary care in SCD management. The focus group discussion was video recorded. The recording was then examined by the project team and recurring themes were identified. A comparison was made with notes made by two scribes also present at the discussion. SETTING: Sickle Cell Society in Brent, UK. PARTICIPANTS: Ten participants with SCD or caring for someone with SCD from Northwest London, UK. MAIN OUTCOME MEASURES: Patients perceptions about the primary care services they received, and a list of key themes and suggestions. RESULTS: Patients and carers often bypassed GPs for acute problems but felt that GPs had an important role to play around repeat prescriptions and general health care. These service users believed SCD is often ignored and deemed unimportant by GPs. CONCLUSION: Participants wanted the health service to support primary health-care providers to improve their knowledge and understanding of SCD. Key themes and suggestions from this focus group have been used to help develop an educational intervention for general practice services that will be used to improve SCD management in primary care

Views of patients about sickle cell disease management in primary care: a questionnaire-based pilot study.

OBJECTIVES: To determine how patients with sickle cell disease (SCD) perceive the quality of care that they receive from their primary healthcare providers. DESIGN: A questionnaire-based pilot study was used to elicit the views of patients about the quality of care they have been receiving from their primary healthcare providers and what they thought was the role of primary care in SCD management. SETTING: Sickle Cell Society and Sickle Cell and Thalassaemia Centre, in the London Borough of Brent. PARTICIPANTS: One hundred questionnaires were distributed to potential participants with SCD between November 2010 and July 2011 of which 40 participants responded. MAIN OUTCOME MEASURES: Analysis of 40 patient questionnaires collected over a nine-month period. RESULTS: Most patients are generally not satisfied with the quality of care that they are receiving from their primary healthcare providers for SCD. Most do not make use of general practitioner (GP) services for management of their SCD. Collecting prescriptions was the reason most cited for visiting the GP. CONCLUSION: GPs could help improve the day-to-day management of patients with SCD. This could be facilitated by local quality improvement schemes in areas with high disease prevalence. The results of the survey have been used to help develop a GP education intervention and a local enhanced service to support primary healthcare clinicians with SCDs ongoing management

Regional variation in trajectories of long-term readmission rates among patients in England with heart failure

Background We aimed to compare the characteristics and types of heart failure (HF) patients termed “high-impact users”, with high long-term readmission rates, in different regions in England. This will allow clinical factors to be identified in areas with potentially poor quality of care. Methods Patients with a primary diagnosis of heart failure (HF) in the period 2008–2009 were identified using nationally representative primary care data linked to national hospital data and followed up for 5 years. Group-based trajectory models and sequence analysis were applied to their readmissions. Results In each of the 8 NHS England regions, multiple discrete groups were identified. All the regions had high-impact users. The group with an initially high readmission rate followed by a rapid decline in the rate ranged from 2.5 to 11.3% across the regions. The group with constantly high readmission rate compared with other groups ranged from 1.9 to 12.1%. Covariates that were commonly found to have an association with high-impact users among most of the regions were chronic respiratory disease, chronic renal disease, stroke, anaemia, mood disorder, and cardiac arrhythmia. Respiratory tract infection, urinary infection, cardiopulmonary signs and symptoms and exacerbation of heart failure were common causes in the sequences of readmissions among high-impact users in all regions. Conclusion There is regional variation in England in readmission and mortality rates and in the proportions of HF patients who are high-impact users
