IRIDE: Interdisciplinary research infrastructure based on dual electron linacs and lasers

This paper describes the scientific aims and potentials as well as the preliminary technical design of RUDE, an innovative tool for multi-disciplinary investigations in a wide field of scientific, technological and industrial applications. IRIDE will be a high intensity "particles factory", based on a combination of high duty cycle radio-frequency superconducting electron linacs and of high energy lasers. Conceived to provide unique research possibilities for particle physics, for condensed matter physics, chemistry and material science, for structural biology and industrial applications, IRIDE will open completely new research possibilities and advance our knowledge in many branches of sci…

An investigation of the compatibilization of blends of polyethylene and a semirigid liquid crystalline polymer

The mechanical properties of blends with liquid crystalline polymers are in general poor and lower than those expected on the basis of additivity rule because of the strong incompatibility between the flexible and rigid components. Compatibilization is then necessary to enhance the adhesion between the two phases and then to improve the final properties of these blends. The addition of maleic anhydride functionalized polymers could give rise to some compatibilization because of possible reactions between the maleic anhydride group and the end groups of the liquid crystalline polymers. These reactions do not seem to occur in blends of polyethylene and a semirigid liquid crystalline polymer. …

Surgeons' fear of getting infected by COVID19: A global survey

During the last three months, COVID- 19 pandemic had led to a serious backlog of operations globally, and plans for restarting operation are imperative. Recommendations for surgical activities were studied, aiming to protect the surgical staff from being infected. In the meantime, it is also important to give attention to the surgeon’s personal feeling during work. We conducted a survey to investigate global surgi- cal practices during the COVID-19 pandemic, and the surgeon’s personal feeling was also investigated in the sur- vey. In this special letter, we performed multivariate analysis to explore factors that associated with surgeon’s fear of getting infected by COVID-19.

Impact of asymptomatic COVID-19 patients in global surgical practice during the COVID-19 pandemic

The rapid spread of COVID-19 has changed the global surgical care. Patients infected with COVID-19 may present without typical symptoms, and such asymptomatic patients may potentially trigger in-hospital outbreaks by transmitting the disease to health care providers and other hospitalized patients. Further, asymptomatic COVID-19 patients have worse postop- erative outcomes with an unexpectedly high morbidity and mortality, reaching 20⋅5 per cent deaths. However, we do not have objective global data on this issue. In an attempt to clarify the current global surgical practice under the COVID-19 pandemic particularly focusing on the preoperative screening of asymptomatic COVID-19 patients, we …
