Preliminary design of the top cap of DEMO Water-Cooled Lithium Lead breeding blanket segments
2020
Abstract Within the framework of EUROfusion R&D activity, a research campaign has been carried out at the University of Palermo, in close cooperation with ENEA labs, in order to preliminary design the top cap foreseen for the DEMO Water-Cooled Lithium Lead (WCLL) breeding blanket segments. Due to the high heat and pressure loads acting on such component, its design results particularly demanding and a specific multi-physics approach is needed, covering several aspects from thermal-hydraulics to structural assessments. Preliminary detailed CAD model of the cap integrated into the upper region of the WCLL breeding blanket outboard central segment has been set-up, equipped with proper cooling …
Determination of ochratoxin A in beer marketed in Spain by liquid chromatography with fluorescence detection using lead hydroxyacetate as a clean-up …
2005
Abstract A new sample treatment for liquid chromatographic analysis of ochratoxin A (OTA) in beer is proposed. Degassed beer is mixed with lead hydroxyacetate, which precipitates some bulk components but does not remove OTA. The precipitate is separated and the acidified liquid is extracted with chloroform. The solvent is evaporated and the residue is dissolved in mobile phase (acetonitrile–water, 40:60, v/v; acidified at pH 3.0 with phosphoric acid) and separated by liquid chromatography using fluorescence detection. The limit of detection was 0.005 ng/ml. The average recovery rate and the average RSD of recovery in the spiking level range 0.01–0.5 ng/ml were 95.5% and about 5%, respective…

A model for a national clinical final examination in the Swedish bachelor programme in nursing
2011
Aim To describe the development and evaluation of a model for a national clinical final examination in the bachelor nursing education.Background After the transfer of nursing education to the academy, concerns have been raised among nurses, nurse leaders, lecturers and researchers about the nursing students clinical competence at the entrance to professional life.Methods During 2003 to 2005, a collaborative project was carried out between four universities and adjunctive health-care areas supplying clinical placements in Sweden. A two-part examination was agreed upon comprising a written theoretical test and a bedside test. An assessment tool for the bedside test was created. Nursing studen…
Career opportunities and benefits for young oncologists in the European Society for Medical Oncology (ESMO)
2016
The European Society for Medical Oncology (ESMO) is one of the leading societies of oncology professionals in the world. Approximately 30% of the 13 000 ESMO members are below the age of 40 and thus meet the society's definition of young oncologists (YOs). ESMO has identified the training and development of YOs as a priority and has therefore established a comprehensive career development programme. This includes a leadership development programme to help identify and develop the future leaders in oncology. Well-trained and highly motivated future generations of multidisciplinary oncologists are essential to ensure the optimal evolution of the field of oncology with the ultimate goal of pro…
Estrategias basadas en análisis de redes sociales para optimizar el clima de aprendizaje en la universidad
2021
The aim of this study was to detect leaders among a group of university students based on their centrality scores and, from these scores, to distribute roles to help enhance learning climate. We understood that learning climate improved when the construction of networked knowledge was stimulated from the perspective of Computer-Supported Collaborative Learning. We conducted the educational experiment in a virtual environment. An online discussion forum was set up in a loo- sely structured format, and the students’ centrality scores were calculated from the social network they generated in the forum. Our findings show that student connectivity increased significantly and that several leaders…
Ambidextrous Leadership, Social Entrepreneurial Orientation, and Operational Performance
2019
In the knowledge era, new forms of organizing and managing firms emerge to adapt to new situations. One such new form of organizational management is ambidextrous leadership. Ambidextrous leadership combines opening leader behaviors, such as promoting creativity, and closing leader behaviors, such as accomplishing objectives and adhering to norms. Thus, the aim is to demonstrate that a social orientation is not at odds with measures of operational performance other than profitability. The purpose of this study is to examine how ambidextrous leadership is linked to social entrepreneurial orientation and how this in turn affects operational performance. This is done through a rigorous review …
