An Additive Model to Predict the Rheological and Mechanical Properties of Polypropylene Blends Made by Virgin and Reprocessed Components
2021
In this work, an additive model for the prediction of the rheological and mechanical properties of monopolymer blends made by virgin and reprocessed components is proposed. A polypropylene sample has been reprocessed more times in an extruder and monopolymer blends have been prepared by simulating an industrial process. The scraps are exposed to regrinding and are melt reprocessed before mixing with the virgin polymer. The reprocessed polymer is, then, subjected to some thermomechanical degradation. Rheological and mechanical experimental data have been compared with the theoretical predictions. The results obtained showed that the values of this simple additive model are a very good fit fo…
Two Treatments for Fear of Flying Compared: Cognitive Behavioral Therapy Combined with Systematic Desensitization or Eye Movement Desensitization and…
2011
This study aimed to test a combined treatment with eye movement desensitization and reprocessing (EMDR) and cognitive behavioral therapy (CBT), compared with CBT integrated with systematic desensitization, in reducing fear of flying. Participants were patients with aerophobia, who were randomly assigned to two experimental groups in a before- and after-treatment research design. The Flight Anxiety Situations Questionnaire (FAS) and the Flight Anxiety Modality Questionnaire (FAM) were used. The efficacy of each program was evaluated comparing the pre- and post-treatment levels of fear of flying within subjects. A comparison of the post-treatment scores between subjects was also conducted. R…

Disposable chlorine dioxide wipes for high-level disinfection in the ENT department: A systematic review
2020
Abstract Background Nasopharyngoscope reprocessing methods should be effective, rapid and reproducible with moderate cost. Tristel Trio Wipes system (TTWS) is a manual reprocessing method based on chlorine dioxide that has lately emerged in ENT department. This review aims to collect evidence on this system. Methods The PubMed, Web of Science and Cochrane Library databases were searched for all the studies on TTWS or one of its components. Data were grouped according to the study type. Results Ten articles were included in the review. TTWS ensured high-level disinfection in laboratory and clinical setting. Although the limitations of the manual systems, TTWS proved to be faster than automat…
