A simple quasi-3D theory for static stability analysis of imperfect FG beam

This study introduces a simplified approach to assess the buckling and static bending of advanced composite beams, including those composed of functionally graded materials (FGMs) with various porosity models. The technique utilizes a straightforward integral quasi-3D approach based on the advanced shear deformation theory. This approach offers several advantages: it simplifies the analysis by reducing the number of unknowns and equations required, improves accuracy by considering the stretch effect across the entire depth of the beam, resulting in more reliable results, and accurately represents shear by satisfying the zero-traction boundary conditions on the beam’s surfaces without the need for a shear correction factor. Additionally, it captures the parabolic pattern of transverse shear strain and stress throughout the depth of the beam. The governing equations are obtained by applying the concept of virtual work, and the Navier solution is employed to calculate analytical solutions for the buckling and static bending of FGM porous beams under different boundary conditions. The approach is in line with and builds upon existing research on FGMs and other sophisticated composite beams, further enhancing its validity and reliability. Finally, computational analyses demonstrate how the distribution of materials, such as power-law functionally graded materials (FGMs), geometry, and porosity, affect the deflections, stresses, and critical buckling load of the beam

Implementing WHO-Quality Rights Project in Tunisia: Results of an Intervention at Razi Hospital

Background: The aims were: 1) to measure the attitudes of learners (and future trainers) before and after a course on WHO-Quality Rights (QR); 2) to evaluate a psychiatric ward, by previously trained staff on QR, comparing it with a previous evaluation and discussing an improvement plan. Methods: 1) Training sample: 19 subjects (8 males), 41.4±10.6 years, including jurists/lawyers, health professionals, and experts. The QR team developed the 26-item tool to assess the knowledge and attitudes of participants. 2) Evaluation of quality of care and respect for human rights in the ward was carried out on 20 staff representatives, 20 family members and 20 users with QRToolkit. Results: 1) Learning in QR has partially changed the knowledge and attitudes of trained people. 2) The evaluation shows significant delays in the implementation of the rights advocated by the United Nations Convention on the Human Rights of Persons with Disabilities (CRPD). In Themes 1, 3, 4 and 5, the evaluation shows no differences compared to 2014, but in Theme 2, the level was lower than four years before. Conclusion: The scarcity of resources due to the economic crisis that Tunisia is going through, cannot be considered the only cause of the delays highlighted. However, it is likely that in a context of uncertainty for the future, scarcity of resources and a decrease in staff (i.e., professionals dedicated to psychosocial intervention) may have demotivated the team towards recovery. The improvement in knowledge and attitudes of many staff members after the training may open future positive scenarios
