Improving Clinical Governance of Kidney Transplantation: Review of a Ruling and of the Clinical Governance Process in the United Kingdom
No full textThe presentation of adverse events and negative outcomes is uncommon in scientific publications, particularly in a highly regulated and scrutinized practice such as solid organ transplantation. A ruling of a regulatory body of the pharmaceutical industry in the United Kingdom generates several considerations, in particular, regarding the governance process of kidney transplantation, as the events reported in the ruling are linked with high rejection rates and negative patient outcomes. This analysis offered a review of the current governance processes, while recognizing the relevant limitations of the system regulating kidney transplantation outcomes in the United Kingdom. The article identified some of the potential interventions that may contribute to delivering an improved governance, harmonizing contemporary practice, modern health care system, and establishing scientific knowledge
High-resolution periodic mode shapes identification for wind turbines
No full textThe stability analysis of in-operation wind turbines is a very important topic, that has received considerable attention in the last years. Many identification algorithms have been developed to estimate frequencies and damping ratios, but very few papers have been dedicated to the mode shapes. The knowledge of high-resolution mode shapes could be exploited for several applications including model validation, accurate description of the vibratory content of a machine and spatially-accurate damage detection. In this work, we will present a procedure to compute the high-resolution periodic mode shapes of a wind turbine, and apply it to a high-fidelity wind turbine model. The results show that this methodology is able to identify the first low-damped modes of the system with good accuracy
Root and crown tot of olive caused dy Phytophthora spp.
No full textPhytophthora root and crown rot has been traditionally considered a minor disease of olive. However, in recent years it has
been recognized as an emerging problem in several olive-growing countries such as Australia, Italy and Spain probably as a
consequence of the expansion of plantings in new areas with heavy soils and the more intensive use of irrigation in both olive nurseries and commercial groves. The disease has been reported from most olive-growing countries and is caused by several soil -borne species of Phytophthora, including P. cinnamomi, P. citricola, P. cryptogea,
P. drechsleri, P. gonapodyides, P. inundata, P. megasperma,P. nicotianae and P.palmivora. Diagnosis is currently based on the
isolation and identification of isolates by both traditional and molecular methods. New molecular techniques are currently available that could be applied for both the identification of isolates and Phytophthora infections directly in host-tissues as well as insoil and water samples. A number of dedicated databases could improve the efficiency of these techniques. Moreover, DNA analysis has greatly contributed to phylogenetic studies of Phytophthora. Control of Phytophthora root and crown rot of olive is mainly based on preventive measures
