No full textAnalysis of the electromagnetic emission of a railway vehicle according to the en 50121-3-1 standard: A case study
No full textWe present a case study on the evaluation of the radiated emission from a railway vehicle according to the EN 50121 standard. Measurements were performed in an open-area test site in two conditions: stationary mode and slow-moving mode, according to the technical document EN 50121-3-1:2018. Magnetic and electric field strengths were measured and compared with limit curves. The considered frequency range is from 150 kHz to 1 GHz. We exploit a time-domain analysis implemented with an EMI receiver, instead of a conventional swept frequency analysis, in order to reduce ambient noise variation, according to CISPR 16-1-1. The usage of a hybrid antenna is proposed to reduce the time needed to cover the 30 MHz to 1 GHz frequency range. We discuss the difficulties resulting from the contribution of external sources, which could be suppressed by performing the measurements in a suitable semi-anechoic chamber, such as the one available at the Laboratories of the Italian Railway Infrastructure Manager (RFI) Osmannoro location. We provide evidence that emission measurements performed in such semi-anechoic chamber yield results in agreement with those obtained in an open-area site

Chronic rhinosinusitis with nasal polyps: how to identify eligible patients for biologics in clinical practice
No full textObjective. This study compared three severity measures for chronic rhinosinusitis with nasal polyps (CRSwNP). The outcome was to identify patients who are eligible for biological therapy. Methods. 330 adult patients with CRSwNP were examined. Nasal polyp score (NPS), sinonasal outcome test (SNOT-22) and clinical-cytological grading (CCG) were compared. Clinical history, past surgery and asthma control test were also considered. Results. Only 45 (13.6%) patients had a contextual positivity to the three severity measures. The concordance among tests was slight/fair. Patients with severe disease (all tests positive) had more impaired parameters. The mixed cytotype (OR = 4.07), nasal obstruction (OR = 10.06), post-nasal drip (OR = 1.98), embarrassment (OR = 2.53) and difficulty falling asleep (OR = 1.92) were significantly associated with severe CRSwNP. Conclusions. To identify candidates for biological therapy, the contextual use of NPS, SNOT-22 and CCG is preferable. In this way, global assessment of CRSwNP, including morphology, inflammation, comorbidity, symptoms and quality of life is possible
