Limitations of physical contacts to reduce exposure to SARS-CoV-2 infected individuals were handled strictly, particularly in medical centers dealing with airway diseases, like rhinology and pneumology clinics. Such measures and reluctance to visit out- and inpatient services resulted in a 82% decrease in consultations to the 12 German oto-rhino-laryngological (ORL) centres forming our database during the 50 days following March 09 in 2020 if compared to the same period in 2019. Our data on CRS care underline reports on undertreatment of non-COVID-19 individuals with several different diseases during the current pandemic. We should try to reduce the toll these patients have to pay as much as possible. We established telemedicine, e-Health and art...

Preliminary data from organ transplant recipients have shown reduced seroconversion rates after the administration of different SARS-CoV-2 vaccination platforms. However, it is unknown whether different vaccination platforms provide different levels of protection against SARS-CoV-2. To answer this question, we prospectively studied 431 kidney and liver transplant recipients (kidney: n=230; liver: n=201) who received either the ChAdOx1 vaccine (n=148) or the BNT-162b2 vaccine (n=283) and underwent an assessment of immunoglobulin M/immunoglobulin G spike antibody levels. The primary objective of the study is to directly compare the efficacy of two different vaccine platforms in solid organ transplant recipients by measuring of immunoglobulin G (IgG) antibodies against the RBD of the spike protein (anti-RBD) t...

Four lines, the strongest of which is due to the SO 3 − radical, are observed in the EPR spectrum of the low-irradiated samples. Another line seems to belong to SO 2 −. The strong line and weak lines with hyperfine structure and lines for pairs of closely spaced SO 3 − centers with a strong angular dependence are observed at high irradiation doses. The main values of the SO 3 − hyperfine coupling tensor and the dipole-dipole coupling constants of the SO 3 − pairs are determined. A quantum-chemical calculation of the electronic structure of isolated SO 3 − and SO 2 − radicals is performed. Values of the g tensors and hyperfine couplings are calculated.

Ai 90 apprendenti che compongono il campione è stato sottoposto un test linguistico. Il test e` stato concepito in modo tale da consentire di verificare la conoscenza dell'uso dei tempi del presente, passato e futuro indicativo e sopratutto la padronanza nell'uso dei tempi passati e in particolare del passato prossimo e dell'imperfetto indicativo. I risultati del test sono stati rappresentati graficamente ed analizzati dal punto di vista statistico per meglio evidenziare le aree dove gli studenti incontrano maggiore difficoltà. In linea dei risultati si e` cercato di segnalare in primo luogo le cause che si nascondono dietro queste difficoltà. Dalla ricerca si evince che il tempo passato indicativo italiano risulta il più difficile da apprendere e che la distanza tipologica tra l'italiano e l'arabo interferisce nel processo di apprendimento dell'italiano.

This congestion was due to the significant expansions in buildings andan increase in the number of colleges in addition to the extensive use of private transport modes by students and university employees. This research was an attempt to find a solution for transportation problems in the UBAC, through studying the current transportation system inside the campus, and then suggesting alternatives to enhance the situation in the Campus and its environs as well. The study solutions focused on replacing the current diesel buses with battery-electric buses and restricting some of the private cars toward the Campus. This study supposes this transformation will reduce the CO2

Our target is to describe a set of related linguistic and rhetoric functions in the field of social and discourse deixis across the two languages. The structure and function of both social and discourse deixis have been studied to highlight their influence on the acquisition of empathetic shift in both languages. In addition, this study shows that deictic forms in Arabic are more pragmatically conditioned than in Italian. As for the empathetic shift, it has been found that Arabic is abundant with the means through which the empathetic shift is carried out. Arabic seems to be very rich in the fields of rhetoric and empathetic shift.
